if 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 was surprised when hypervm brought in a 64bit guest os. Maybe it's me..but...is this a good idea? Maybe it works fine.. it just does not *seem* like it would.
View 9 Replies View RelatedHow 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.
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 3 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?
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.
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 -

I'm configuring a website for a client who has moved their web hosting to downtownhost, but is keeping their email hosting with their current provider. They do not want to configure an MX entry on DTH to autoforward email back to their current provider because they don't want their email to pass through DTH.
In order to do this, do I keep the nameserver entries on the current provider the same, and configure an http redirect to point to DTH? Or is there something else I should configure on the current provider?
I'm wondering if you can tell me something about your experience with a host/server in a different country or overseas.
My webpage will be mostly frequented by Australians.
What do you think is the advantage and the disadvantage of having a host in your own country and having one overseas?
I'm thinking about stability, traffic speed, peak hours in different time zones, customer service, ....
What are your experiences?
I was with Blue Host and their support and service was pretty bad. Servers going down all the time, and chat support was terrible. Then I moved to Host Monster and received the same kind of service/support. I later then figured out that Blue Host and Host Monster is runned by the same people. For example, I opened up a tech support ticket with Host Monster and then they replied signing their signature with Blue Host. So I got the same service: terrible tech support and servers kept going down. Now I'm looking for a new web hosting. I a few people here gave Host Gator some good reviews. I hope Host Gator is not run be the same people that runs Blue Host and Host Monster.

This is for just a couple of simple domains and sites to be hosted.
with this being my first website goddady's website tonight or there blog site plan seem pretty good as I do not know how to build a professional looking website nor do I have a knowledge of HTML. Are there other hosts that offer better services such as these?
Also I would want to register with 1&1 as to register privately is free but with godaddy it costs around $15 and I've heard of godaddy stealing persons domains when they haven't even expired yet i.e. familyAlbum.com?
Is it allowed for instance to register my domain name with 1&1 and host my site with godaddy?
If you had to chose either Host Gator or Hawk Host which would you go with and why? Don't bring any other hosts into consideration just compare these two. This would be for a standard website, forum, and a few downloads if it makes a difference...nothing too fancy.
View 14 Replies View RelatedI have just made a personal website using photoshop, html, css and php. My site contains an index page, a gallery page with 8 photos, a contact page with a form and an extra page with some quotes. I am planning to use a paid host for the first time. Based on feedbacks from some of my sitepoint friends, I decided to go in for shared hosting. I thought of using Hostdogs.com as they have the option of a monthly billing cycle. I thought that I have the option of changing my host after a month if I am not happy with them. I have also read a lot about Hostgator.com. A lot of sitepoint members seem hooked to it.
1. Can anyone give an opinion as to which host I should go in for? Hostdogs also give a free domain. Is there any reason I should go in for Hostgator instead of Hostdogs?
2. One more question, I have heard that once I have a site running, I can earn money through the advertisements placed on it? How do I place advertisements on my site?
3. One last and very important question is whether it is right to go in for shared hosting at this point of time. I just read this
Quote:
When you look for a suitable host, be sure to check out the amount of bandwidth that will be available to your site. Even a site that doesn't require a great deal of data transfer per month could run slowly if you're hosted on a shared server; particularly if you are on the same server as a more popular or bandwidth-intensive site.
The more sites hosted on a server, the more likely they are to compete with each other for available resources, including bandwidth. This is why you may notice a reduction in server response times during busy periods, or during a sudden peak in traffic at a busier site on a server that you share.
This made me wonder whether I should go in for shared hosting. But then mine is a personal home page which may not have so much of traffic.
4. What does the paragraph below mean? How does one handle ones registration manually?
Self-Management (no cost)
Select this option if you prefer to handle your registration manually.Your web host can establish service with any Top-Level Domain (TLD), international or domestic.
I will be setting up a site which uses ASP.NET 1.1. I know versions 3.0/3.5 are available, but they are not yet V2.0 compliant. Anyway thst is not the issue - just context.
Would like your advice as to whether it would be better to host this site with a company who looks as though they are specialising in ASP; such as DiscountASP, or Softsyhosting, or go with a general Windows hoster such as Steadfast, Fluidhosting, or 3Essentials?
I know nothing about ASP, so I don't know whether it is not at all neccessary to have a host specifically knowledgable about it, as I am unlikely to ever have problems with it, OR; I will most certainly have to address ASP issues sometime, so it would be essential to have support who really knows ASP.
I got the beta of vis studio 2005 about a month ago and happily started coding away. I recently told my host to convert to asp.net 2.0 so I could upload the stuff and have it work and he said he couldnt until the non beta comes out.
Is there anyone out there at the moment who will host asp.net 2.0?

I just want to ask the community of WHT a series of questions about shared and reseller hosting and what you would like out of a shared/reseller host.
What do you look for in a web host (in terms of shared and reseller hosting).
Do you prefer cheap "unlimited" and "unmetered" plans?
Would you like support through live chat, phone, or helpdesk?
What kind of price range would you consider reasonable for a shared hosting plan? a reseller plan?
Would a community forum with support staff and other clients be a plus to you?
Does the site's design and the software it utilizes be a concern to you?
In your opinion, what would make you choose a specific web hosting company over any other?
Anyone have a recent bad experience with 247-host.com?
