After a yum update on a centos 5.2 box (including an update to the latest version of xen) my guests don't have a network connection anymore (nor windows, nor linux VMs).
The windows VM does see an unknown PCI device (great, no drivers and no internet), of which I guess is the network card seeing there are no other network cards listed in the VM.
Can you put two of these supermicro mini servers back to back in a standard rack? I am looking at the [url]
View 14 Replies View Relatedif its actually possible to properly run a 32bit guest under a 64 bit xen host.
I'm using hypervm.
64 bit guests work perfectly, no problems.
32bit guests boot, but when i try for example, yum update, it will try and install 64 bit packages and fail.
I have been using Linux for the past 3 or so years, either running it for workstations or servers, and now I want to set up a server for Virtualization. I have been doing a fair bit of research about the different ways of doing this, and I have decided to go with KVM. I usually use CentOS, but will have to use Debian to use KVM. I just have a few questions about the best way of setting it up.
We have a pretty powerful server* which we are planning on collocating to a data centre and running web servers from the VMs. Virtualization seems like the best way to allow for simpler administration, and also allow us get the most out of our server's resources.
*Intel Xeon X3230 Quad Core, 8GB Ram, 4x 15k 147gb SAS (RAID 6)
What is the best way to set this up then? I was thinking we could install Debian as the Host/Hypervisor over the whole drive, and give it a 16GB swap partition. Then I guess when the VMs are installed they live on the Debian drive as a file, or do they need their own partitions?
Are the guest OS's capable of using the Host's swap space? Its bad enough losing 16GB as a swap partition to the host OS, but please don't tell me I need to supply the VMs with their own swap partition aswell - im curious as to if the server will ever need to use swap space as it has alot of ram, let alone require extra swap for each VM too?
KVM is still very new, but does anyone know any good books/resources out there? The virtualization books I have seen don't seem to cover KVM, just Xen and others.
Let's make this straight,
I have this vps,which is pending cancellation in a few days.
Hardware Node = EL 5 x86_64,
Vz = Xen
I asked my provider for 32 bit centos, I even rebuilt it, but my "uname --all" still
Quote:
Linux xxx.xxx.com 2.6.18-128.1.10.el5xen #1 SMP Thu May 7 11:07:18 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
so I opened a ticket asking about the vps arch.
The provider have told me that to run a vps 32 bit guest, what you have to do is (?)
+++++++++++++++++++++++++
yum clean all
echo i686-redhat-linux > /etc/rpm/platform
+++++++++++++++++++++++++
so yum will exclude any x86_64 packages.
The provider has told me also that my "uname" display x86_64 because the hardware node is 64 bit. Is this true ?
I'm no linux or vps guru, but that's doesnt feel right at all.
This has cause me some issues especially with kernel-headers and some program failed to compile.
So, is it possible to run a 32 bit OS as xen guest inside 64 bit node?
For all of you who are ordering / have ordered VPS systems, what do you think about having Windows vs Linux available from your provider?

View 9 Replies View RelatedOKay here is the set up:
I have a CENTOS 64bit running, with 1 guest OS (WinXP) in a VMWare Server. I have tried the following: I have 6 public IP's attached to my 1 Ethernet card in the CENTOS host.
Try 1:
The Guest OS is set to use "Bridged" Networking. This allows full use of the internet, in both directions. Not exactly optimal, but it does work. I can reach the Guest via RD, which is a requirement for this client. The guest OS is mainly assigned one of the 6 public IP's (x.x.x.118). The problem with this setup is the Guest OS can not reach the host. For example the host has a mail server on it, and when the Guest tries to reach the host, it times out.
Try 2:
The Guest OS is set up to use "NAT" and gets 192.168.100.128 as its IP via DHCP inside of VMWare. The nat config file for VMWare is set to open port 3389 (RD port). Guest OS can reach the host with out any problem, and can reach the internet with out any problem, however I can not RD in to the Guest OS.
I prefer setup number 2 for all the obvious reasons, but I just can not get my IPTables rules to work. This is what I thought should work, but does not:
iptables -t nat -I PREROUTING -d x.x.x.118 -j DNAT --to-destination=192.168.100.128
iptables -t nat -I POSTROUTING -s 192.168.100.128 -j SNAT --to-source=x.x.x.118
I realize that would have done all traffic, and defeated the benefits of NAT,but since forwarding only 3389 was not working I tried forwarding everything.
Any suggestions?
I've just downloaded Microsoft Virtual PC and the Internet Explorer 6 Application Compatibility VPC Image containing an XP installation for testing sites with IE6 [url].
Everything works fine, I chose VPC Shared Networking (NAT) and I can access the internet from the VPC as well as my Apache development server which runs on the host OS (Win XP) by going to the host's IP address which is [url] in my case. And here I have 2 problems:
1. I want to access [url]on VPC just by typing [url]. I added the following line to the hosts file:
192.168.52.141 localhost
But this doesn't work. Interestingly, any name other than localhost works fine, for example:
192.168.52.141 localhost.localhost
or
192.168.52.141 local
This is not a major problem but I'd prefer localhost. Any ideas how to do that?
2. And the more important issue: on my host OS I have some development sites which I have set up to be accessed by subdomains, for example [url], in httpd.conf:
Code:
<VirtualHost 127.0.0.3>
ServerName perfekt.localhost
DocumentRoot C:wwwperfekt
DirectoryIndex index.php index.html
</VirtualHost>
and in hosts file:
Code:
127.0.0.3 perfekt perfekt.localhost
And now I want to access this site from my VPC too by using subdomains like this! How can I do that? The address 127.0.0.3 seems to be local to the OS and VPC can't see it. I have tried setting other IP addesses in httpd.conf but nothing outside the 127.x.x.x range works on either OS. I suppose I need to make each of my sites to be seen under a different IP from the outside network so that VPC (which is "outside" the host OS) can access them - then I just set up the appropriate subdomain names in VPC hosts file -
How do I run a virtual instance of Windows server 2008 on my Linux dedi? Do I need to partition the server and create a VPS for this or can I run it on something like VMware? (Please look at my other thread here [url]t=857377 to learn more about my server, its resources and current config.)
Why would I want to do this? Because my primary desktop OS is still Vista Ultimate 64 and I've invested a lot in Windows-based software and hardware--too much to make a total switch to Linux. But, I don't want to invest more than I have to in order to run a Windows server that allows my business partner to access documents remotely or for us to share various files securely and privately and still serve my mostly Windows-based clients and colleagues. I'm one of, well, two people I know who even use Linux (at least at the OS level and know it).
Since my research shows I **can** do this on Centos 5, the responses that would be most useful to me would be those that focus on how I can do this successfully (even if it seems complicate; I can figure it out with help and/or direction) and what to consider or avoid when creating this virtual guest OS on my Linux dedi.
how to install Ubuntu (either 7.10 or 8.04) as a XEN domU guest on a CentOS 5 / Fedora Core 8 XEN dom0 server?
I have tried installing Ubuntu as a fully virtualized guest, but the Ubuntu CD doesn't even bootup. I get the Linux bootloader, and that's it,it doesn't continue to boot. Odd.
When trying to install a Paravirtualized guest, I had to use the debootstrap method, but can't get it to boot up.

Many of the VPS providers I've looked at don't back up the servers that house the VPSs and as such don't back up the VPSs either - have you considered what would happen should the VPS itself be erased (such as what happened to vaserv/fsckvps not too long ago)?
View 14 Replies View RelatedAny active/current comments on OC3 Network?
Mainly looking at their un-managed server but I would like to know some responses concerning their support. What level of support do they provide? Is it efficient and time effective? Will they charge me for the little-ist of a request (Let's say I get an internal server error in WHM caused by a software update -- will they roll me to a backup for free or will I be charged?).
So, just looking for opinions on their support quality and availability, and their server uptime and happiness of current and past clientèle.
I see Enotch Networks offer in vps offer forum and i think to take from them.
But i want to check before about them , did anyone here host with them?
Did they have any problems with there servers and support?
Did they suspended the account if it use half of that bandwidth which is it offered , like as i see in there offer the bandwidth can be 6600GB monthly , so if i use more than 4000GB, did they will suspend my account?
And if there are anything about them i hope to post here to have a clear image about them.
My server has recently been attacked by members of the following website, using DDoS tools stolen form other script kiddies and rebranded (oh the irony). Having enough, I decided to go on a mission to get these brats shut down:
troyrulz007.com
The site is also filled with links to illegal downloads, porn, etc.
The first thing I did was report them to their webhost. I figured this was the best first step. I opened a ticket and reported what was on the site, and pointed out which parts of their AUP the site was violating. After a few days, I provided them contact information for someone at Rockstar Games, as this site was providing downloads for one of their most recently released titles. I also went ahead and contacted some of the publishers of the software being provided illegaly.
14 days later, the ticket is silently closed with no action taken. Site is still up and still providing illegal downloads of software that people spent a lot of time and money developing.
I know they are a VERY small fish in a large pond, but I had had enough of having my servers crippled (at least know I've learned how to defend against it) and decided I would strike back legally and without stooping to the script-kiddies level.
At this point, I'm convinced Virpus Networks (virpus.com) doesn't give a flying monkey turd about anything other than collecting their pathetic $10/mo.
Was I wrong in assuming they would do anything? Should I have just ignored it and moved on? If not...how do I find out who provides network service to Virpus. I'm sure THEY don't allow this sort of thing.
Maybe I was just being a cry-baby and should've left it alone. I don't know.
But hey...I guess if you want to host a site that breaks pretty much every rule in the book, you know where to go. Looking at their pricing however...yeah I'll not go there on that one.
Anyways...this is a part rant, part notification, part "am I being a whiny jerk" post. Sorry if it breaks any rules.
Thanks for listening. I'd give you that portion of your life back if I could but I've decided to keep it for myself.

I recently migrated a dedicated srv to InterWorx running Lite Speed (as apache) on CentOS 5. (srv was running PSA 9 on CentOS)
Being the NEWB that I am.....I needed a little "hand holding" with this setup (especially the Lite Speed config). SFN support went way out of their way to assist. What is enjoyable about their support is the tech's have never responding to many of my "NEWB" questions in a demeanoring way. They explain things in detail. Tickets are always answered promptly.

they provide me a KVM and after some days when my time over so there is another server in my KVM account and i am able to access that server also can't believe ? well i am ready to show proofs...
and the 2nd funny thing is i told them about this but still they dont change the passwords etc i have full power on some other person server
THIS IS ONLY MY REVIEW ABOUT THIS COMPANY BECAUSE IF ANOTEHR SERVER IN MY KVM SO MAY BE MY SERVER IN ANOTHER...
Well it's been one month since I purchased my dedicated server from Limestone Networks, and i'd like to post my experiences with them, so here it goes.
About a month ago I stumbled upon Limestone networks, read a few reviews, and thought i'd go for it. The the next thing I did was start a live chat, a friendly chap by the name of Felipe responds. I have a nice long chat with Felipe, what a delight it was! Not only did he answer all of my questions promptly, but he certainly knew what he was talking about. Unlike my previous experiences with other companies.
After a nice long chat with Felipe, I was ready to get my server. So I went straight ahead and ordered.
Specifications:
Dual CPU Quad Core XEON 5504 (2.0ghz)
8GB DDR2 ECC registered RAM
2x500GB HDD in RAID1 (WD RE3, AWESOME HDD'S!)
4TB bandwith
100mbps up/down speeds
IPKVM included
All up cost me around $280 + ~$30 setup fee
Within about 2 hours I receive an email stating that there were some minor problems during setup because of the RAID configuration, and they will fix it as soon as possible. I must admit, it got me slightly worried, but a few minutes later, I receive another email saying that it's all setup and done! Boy was I excited!
I Instantly SSH'd into my server to check on things, all good. I install the XEN kernel and reboot to make sure it's working all fine, boots without any errors. So far so good.
A few days later I realised I was running out of IP Addresses, so I open a support ticket to ask for more, the invoice is created, I pay it then respond saying that I have done so. 6 minutes later they respond saying that it is being set up, and another 3 minutes later they respond with the IP addresses, sweet.
Later on I opened another support ticket asking a question referring to upgrades. Out of pure boredom I clicked the send receive button on my email, and sure enough, I already had a response! all within about 2 minutes after sending it.
Limestone's service has been great, I love their support and prompt response to tickets! One minor problem is that their accounting department isn't available during all hours, no biggie though. Their technical support department is open 24/7.
One great bonus with Limestone is that they keep you informed every step of the way, rather than leaving it to the last minute to say "sorry about the wait".
When i'm ready for my next server, i'll definitely be going for Limestone.
I ordered my server on March 6th, and asked for the server to be provisioned the 10th. I wanted to test some things out, and so I wanted the server earlier. I called up LSN and got to Carl. He was great and totally understood everything and provisioned our server in a matter of 1 hour 59 minutes!
Sadly, because I had told them we were going to need the server on the 10th, they thought they would have the RAM we needed. They compensated us by adding a better CPU(Q9400).
Then the RAM came in, I think 5 days later because of a shipping mistake where it didn't get on the truck I think(Not LSN's fault). The server went down, and they installed the RAM. The server wouldn't boot, so we had a few problems there. In the end it was just an oversight of the max amount of RAM that the MoBo could support. The downtime was a bit excessive in my opinion, and LSN compensated me.
I have had zero problems with them since that incident.
Right now, I am purchasing a 2nd server with LSN.
Support 9/10
Sales Staff 10/10
Accounting 10/10
I tried to search as i have seen there plans are cheap.
View 0 Replies View RelatedI have been using R-fx software since somewhere in 2002 if I remember correctly.
I have been a happy using of APF, SYSBK and BFD for a long time. I have also installed other software of them, but I choose to keep my server as clean as possible. So LES, LSM, NSIV, SPRI were never installed. I had temporarily installed PRM and SIM, but I choose to uninstall them for various reasons.
I am wondering if you people still use APF and BFD. I will keep on using sysbk as it's a very simple program that can do no harm to my server, but I'm not sure about APF as primary firewall.
I have never been impressed by the role of firewalls in server security. I think they are mostly excaggarated, especially hardware firewalls, and iptables can do anything that is required.
How do you feel about using CSF on new servers rather then APF? Do you recommend any r-fx software for good server security and performance? Rf-x is about security, stability and speed (performance). I like that.
6 months ago I signed up for their services, moving away from 1&1 shared hosting. So I spoke with Andrew about getting a server for the things I do. We worked a deal, which is probably too good to be true.
Im running on one of their Dell 1425s. I have servers here at the work (designing agency), so I know my way with servers etc etc. The performance of their network and support 10/10 I had no problems and although unmanaged, I was always able to get help and support.
They look like a new emerging host, but I recommend to give them a try. I've just picked up another server with them ($15 for my first month is quite a steal imo)
just noticed my server is EXTREMELY slow... as well as the limestone network control panel. I had a friend of mine test it too, slow for him. My load is nice and low.. Maybe they are getting DDOS'd? I moved from Burst to limestone and paying alot more, I expected more.
if anyone else is having a SUPER slow connection to the limestone network? I'm about to call their support
After stumbling upon limestone networks amazing offers, I decided to take advantage of their cheapest special for it was more than what I needed. For 135 dollars a month, I got this special:
[url]
With an 100mbps uplink connection. With this dedicated server, I planned on running game servers, and so far it has far exceeded my expectations.
Let's begin with the set up time:
Before leaving my old host, I found out that the location was doing no good for me. Players were not able to query my game server in the game's server list, so I decided to switch hosts. After finding limestone networks, as listed above I went straight ahead and bought the server at 4:00 AM EST time. After two hours of waiting, my dedicated server was set up with HPET enabled like I asked. I was amazed at how limestone was able to set up the dedicated server so fast and at such an early time!
The support:
The support is absolutely hands down AMAZING. Every support ticket I have made was answered (not over exaggerating here) within 4 minutes.
The control panel:
The control panel limestone has to offer that comes free with your dedicated server is so simple to use. (I believe they call it rockware.) There is an option to manage each one of your purchased servers, an option to restart your server, add new ips, change your uplink speed from 10mbps - 1000mbps (depending on what you have), the ticketing system, and much more.
Now the only problem I have came across which isn't all that huge, was that after redirecting all the traffic from my previous game servers to my new game servers hosted with lime stone, I had a problem installing the game files off Steam via hldsupdatetool.exe for Team Fortress 2. The install just froze. So I decided to contact limestone support. They decided to give it a shot, and it seemed that it froze for them too. However they did not give up, they kept trying and trying keeping me updated. (let me also remind most of you that team fortress 2 is a 3.2gb game so it takes atleast 20 mins+ to install all the necessary game files.) Finally after 2 hours, it worked. I was happy. The point here is that the support is probably their best feature aside from their prices and amazing specials. They just never give up and work to their potential in helping every customer. I would recommend limestone to anyone who is willing to try a new host.
Although I have been with them for about a week, they have so far never ceased to amaze me with their support, and quality they have to offer. I will keep everyone here updated on what limestone has to offer me and how well or bad they have been doing at the end of the month when I have to pay my next invoice.
