Performace Of Windows Inside Xen & VMWare VM
Sep 16, 2008
I need several Windows VMs to test out some softwares and I plan on using virtualization technology to cut some costs.
I have a Linux(Debian Etch) dedicated server sitting to accomplish this.
Specs are Quad Core Xeon 2.13Ghz with 4GB Ram/500GB HDD.
Now if I were to choose between Xen 3.1 and VMWare Server for the virtualization technology which would provide better performance?
I tried Windows on Xen 3.1 with PV Drivers and it seemed some what slow, but I'm not sure what the case was there so I can't say which would provide better performance overall.

I have been reading quite a bit lately about the Internap FCP. I am wondering how much it actually improves network performance and how it compares to BGP4. We currently use BGP4, but are considering using a data center with the Internap FCP for a project for a client.
I am looking for reviews from others who have experience with the Internap FCP and it's performance. How does it compare to a network using BGP4? I know that FCP uses more intelligent routing than BGP, but how big of an improvement does it make?

I have Windows Server storage server. However I need to run some Linux scripts. Is it possible to run possibly VMWARE to have Linux so I can install the scripts use the Windows which has content to be used.
Kinda tricky I know but worth a shot.
Windows - Has all the content , but can't run scripts such as file hosting , streaming server (WMV wont do) , HTML/PHP server scripts.

I installed VMWare Server 1.0.4 on my dedicated server, and set-up a new Windows XP Professional VM.
I have 3 more IP's that are not used.
When installing the VM, I used NAT networking to share my main OS network with my private VPS, but basically no one can access the VM from the outside world. I can surf the net while being on NAT status in the VM, but if I try to run any service like Apache, no one can enter to the service besides the localhost.
My VPS is running Windows XP Professional SP2 with a legal retail license and my main OS on the server is CentOS 4.5 (detailed hardware is mentioned below)
Do you have any idea how can I configure my network so anyone can enter the VPS?
And please, if you can explain me step by step because I'm a real newbie hehe

I yesterday installed VMware Server under Windows Server 2003 x64, Enterprise Edition, and have this morning noticed the message 'Service unavailable' when browsing to a website hosted on the server under IIS. I have briefly looked into the problem and found the DefaultAppPool stopped, but after restarting it, it resets back to the stopped state when I once again browse to a hosted website.
Does anyone have any experience of this problem and a workaround?

I have this nice vps, but its on linux, and I always wanted to run windows apps on the vps, because of the nice configuration. I already tried wine, but most of my windows apps don't work, cuz they require .net framework to run.
I tried to instal vmware server and virtualbox, but both of them complain about a kernel problem, they are unable to locate my kernel source, so they can't run.
I am linux newbie, and i am running on a centos 5 operating system.
Some people say its impossible to run virtualization 'inside' virtualization, but i already read some people that say its possible.

I've been using Clearancerack for about 4 or 5 months now and feel I should write an honest review about them considering there really doesn't seem to be too many.
Ever since the start several months ago, I've had nothing but a pleasant experience working with Chris and clearancerack.
So, here we go they get a :
Setup: 10/10
The setup is stellar. The first server I ordered was up the night that I ordered it (only a few hours) all ready to go. The servers even come with a free apc remote reboot port!
Pricing: 10/10
You could not ask for more affordable pricing than that of ClearanceRack, considering the extraordinary support, network, and all around company. Their prices are cheaper than those of the highest quality competitors, yet provide even higher quality service!
Even collocation pricing is very affordable! I will probably be sending up a few nodes in the next several months.
Network: 10/10
There has not been one second of downtime in the month's that I've been there. There was an issue with the network routing once, using bandwidth suppliers that the DC has connections to, yet Clearancerack does not use. This was fixed within several hours as well.
The network consists of a BGP mix of Peer1, All Stream, Shaw Big Pipe, MCI and peering to TorIX.
Almost all of my users experience faster downloads around the globe on the ClearanceRack network, than several of the other networks we've used throughout the US.
Support: 11/10 - Yes 11...
The support is stellar. They provide 24/7 E-mail (it really is 24/7) and REAL HUMAN Phone support (you won't get the usual leave a message, unless they really are busy and cannot take your call).
At any time of day you email them, you'll have a response within minutes, even sales!
We've had one issue with one of our nodes in which Chris had to go into the datacenter to take a quick look. The issue was resolved in 30 minutes at the most.
Any requests we've made, whether it be licensing, IP allocations have all been handled extremely quickly, no matter what time of day it is.
Company:
Many times you'll hear people say, "They're great for a small scale company." Meaning, they're decent, but do have their downs that the higher scale competitors don't. Its not like that at Clearancerack. Every single thing about them is stellar, and the service is MUCH better than service I've received at various considered "higher scale and known" datacenters around the globe.
Clearancerack, ran by Chris - is ran by REAL people, wanting to make a REAL difference in the hosting market, and he/they are doing an amazing job at that.
You don't experience any poor customer service that you'll experience elsewhere. They are 100% honest with any sort of question, issue, or comment you may have. You WON'T get any of the lies, or uninformative information you receive elsewhere when an issue arises.
Personal:
Chris, I will continue to be working with you for many years to come, as I hope many of the current subscribers, and the future do to. Someone like you deserves the very best, and should GREATLY succeed in their business career. - Thank you for everything Chris! - You really know what hosting is all about.
Thats It!
Thanks for taking the time to read this review.
Generally you won't find a honest review with the ratings that I've given these guys, but THEY do deserve it, at the very least. I do not have one complaint about them as I do many other providers, and I've tried many throughout the globe.
I hope you will go ahead and try ClearanceRack for your dedicated solutions needs. They have no contracts, so you can sign up for one month, test out the service and make a final decision (although I can pretty much guarantee you will stay!)
Hostingcon:
If your going to hostingcon, check em' out! They have their own booth there!

I connect to my email on my dedicated cpanel/whm server by TLS/SSL (similar to instructions here: [url]..same ports, etc.)
Today I login & get a "This server's certificate expired"
But it didn't. I purchased a NEW one June 1st. Why is thunderbird grabbing my old ssl cert? The website's https:// works perfectly.
I also checked the server ssl self-signed certs and all are up to date.

I have a PIX501 firewall with a wireless network attached to the outside interface and our local network attached to the inside interface.
I've setup access lists to permit the wireless clients attached to the outside interface to be able to access services on our inside interfaces.
The wireless clients are on a totally seperate /24 subnet.
Now everything seems to work fine with nat statements for our local wired subnets for example wirelessClients accessing the email server etc however the wireless clients cannot access the internet.
For the wireless clients to get out onto our internet connection they have to take the following path
wirelessLaptop - CiscoAccessPoint - OutsideIntPIX501 - InsideIntPIX501 - CiscoSwitch - InsideCorporatePIX515E - OutsideCorporatePIX515E - Internet
Below is a cut of some of the PIX501 config that the wireless clients are connected to.
name 10.1.1.2 accessPoint
name 10.1.1.0 WirelessLan
name 100.100.100.1 pix515fw
object-group network WirelessLan
network-object WirelessLan 255.255.255.0
object-group network WebAccessNetwork
network-object pix515fw 255.255.255.255
object-group network InternalAccessNetwork
network-object ..All our local servers here...
object-group service WebAccessUDP udp
port-object eq domain
object-group service WebAccessTCP tcp
port-object eq www
port-object eq ftp-data
port-object eq domain
port-object eq ftp
object-group service InternalAccessUDP udp
port-object eq all our local server ports
object-group service InternalAccessTCP tcp
port-object eq all our local server ports
access-list outside_access_in permit udp object-group WirelessLan object-group InternalAccessNetwork object-group InternalAccessUDP
access-list outside_access_in permit tcp object-group WirelessLan object-group InternalAccessNetwork object-group InternalAccessTCP
access-list outside_access_in permit udp object-group WirelessLan object-group WebAccessNetwork object-group WebAccessUDP
access-list outside_access_in permit tcp object-group WirelessLan object-group WebAccessNetwork object-group WebAccessTCP
ip address outside 10.1.1.1 255.255.255.0
ip address inside 100.100.100.2 255.255.255.0
nat (outside) 0 WirelessLan 255.255.255.0 outside 0 0
static (outside,inside) accessPoint accessPoint netmask 255.255.255.255 0 0
static (inside,outside) InternalSubnet1 InternalSubnet1 netmask 255.255.255.0 0 0
access-group outside_access_in in interface outside
route inside 0.0.0.0 0.0.0.0 pix515fw 1
route inside InternalSubnet1 255.255.255.0 OurLocalRouter 1
So my question is how should I go about giving the access for the WirelessClients to be able to open web pages on the internet? For that to happen
the traffic has to pass through the outside interface on the 501 firewall out of the inside interface onto the local switch and then back out of our
main PIX515E to reach the destionation.
I'm fairly sure I'd need to modify the WebAccessNetwork access-list to permit WirelessLan to any against the port listings so thats not a problem I can change that
how I'm not entirely sure I to go about it with the NAT statements.

I'm trying to establish a VPN server inside a Fedora 10 VPS under OpenVZ. Openswan or Poptop is preferred over OpenVPN because Windows has built-in support for these protocols.
It looks like the host node (it's actually the vps from myprohost.com) doesn't have the required kernel modules enabled(installed?). Take Poptop for example, if I run pppd after rpm installation, the output is like this:
[root@v ~]# /usr/sbin/pppd
/usr/sbin/pppd: This system lacks kernel support for PPP. This could be because
the PPP kernel module could not be loaded, or because PPP was not
included in the kernel configuration. If PPP was included as a
module, try `/sbin/modprobe -v ppp'. If that fails, check that
ppp.o exists in /lib/modules/`uname -r`/net.
See README.linux file in the ppp distribution for more details.
[root@v ~]# modprobe -v ppp
FATAL: Could not load /lib/modules/2.6.18-92.1.18.el5.028stab060.2/modules.dep: No such file or directory
And when I check for the availability of the encryption module "MPPE", I got the same result:
[root@v ~]# modprobe mppe
FATAL: Could not load /lib/modules/2.6.18-92.1.18.el5.028stab060.2/modules.dep: No such file or directory
Openswan complains about some missing kernel modules too. So what do I do? Do I tell the provider to enable these modules? Do they normally do that? Will the host node require a reboot after having done that?
What modules are required for Poptop and Openswan? And, do I need to tell them to re-enable these modules every time I rebuild my OS?

I've got a dedicated server running my portal. Now we plan to soon launch broadcasting, where we via a webcam + microphone will broadcast (streaming WMV media) to all our members. Our members will then be able to interact with the speakers via chatting.
Now we are currently undergoing loadtesting, with our current setup, which is:
1. dedicated server+ultrafast connection=>chatting
2. home PC with static IP and 1 MBit upload=>Video+Audio Streaming
So the member requests a page from the dedicated server, which has a chat window and a windows media player. The player will retrieve the video/audio content from the home PC. This is done by the client.
Now is pretty logical to see that there will be limitations in how many connections the home pc will be able to handle.
The question is: How do i make the dedicated server get the content from the home pc (so it only serves one connection) and then get all the clients to get their video content from the dedicated server ?
I've looked into the proxy modules for the apache server, however they (forward/reverse proxy) both passes the connection on to the remote machine and thereby not doing what I want to do.

We are running the latest Plesk 12 under CentOS 7.
While I can see the App Owncloud as Admin in the Application Vault my users cannot see that particular app in their Application pool. They can see all other apps though. Just not Owncloud.
All resellers and customers are allowed to install everything from the pool and i selected Owncloud in the Vault already and "made it available" .. Though it is not shown.

I have following Warning when creating a new Domain inside a Subscriptions:
I found this Article: [URL] .....
But in my case this does not solve the Problem.
1> All permissions are right.
2> When I type command '/usr/local/psa/bin/repair --restore-vhosts-permissions' i get the answer 'Directory permissions were successfully updated.'
3> The Order of Webuser and FTPUser (as described in the article) could also not be the problem, because in my case there is only one user (There is only Webuser and no FTP-User.)
4> When typing '/usr/local/psa/bin/repair --update-vhosts-structure' I get the following error 6 times each:
Code:

To get the error 6 times seems to mean, that i have this problem with 6 Domain.

I am going to be sending a 2U server in for colocation. It will be running CentOS 5 64bit at the core and be utilizing VMware for virtual machines.
If I get say 8 ( 5 usable ) IPs as apart of my colocation plan, how can I delegate which IPs goto which virtual machine?

Does anyone here use VMware server on a dedicated server to run Windows or other OS? And in terms of IP address how would this work? Do you need to set the VM as being NATed, or does it have it's own external IP? In terms of performance on a typical 100$-200$/mo dedicated server, how good is it? All these factors depend on a lot of things and I realize that, though. (what apps run, etc)
And do server providers even allow to install something like this? I've never leased a dedicated server before but I'm thinking of getting a linux one, but also running a windows VM for a RunUO server, and unfortunately that only runs in windows. I want a linux server as I prefer LAMP for hosting, and I'd try to get a few clients on the server just so I can pay it off monthly. Also Linux servers are generally cheaper monthly and I like the idea of using SSH tunnels rather then straight RDP, which gives me chills just thinking of, from a security perspective.

Not to start a flamewar, but I was curious about real world scenarios, and peoples experience with and recommendations for either.
I have been asked to plan out a smallish virtualization environment (10-12 Dell hosts, iSCSI Equalogic backend), and when reviewing the cost of going with VMWare over Citrix, I can't seem to justify the costs. I figure since Amazon runs on Xen, it must be pretty decent, but am I missing something?
