64bit Guest Os On 32bit Host
Sep 9, 2007I 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.

32bit Vs. 64bit
Mar 3, 2008I have been trying to research this but I cant seem to find an answer.
The big question I am trying to figure out is the comparison in clock speed for different processor bits.
For example, a 32 bit Pentium 4 at 3.2ghz versus a 64 bit AMD Athlon 2.0 Ghz?

Choosing 32bit Versus 64bit OS
Jun 13, 2008I'm in the process of preparing to install CentOS 5 on my server, and was wondering whether most people recommend going with the 64bit version or sticking with 32bit. My server's CPU is 64-bit capable (Xeon 3060 at SoftLayer), and I have previously run CentOS 4.4 64bit on it, though I did have some struggles from time to time getting things to work (following setup guides that tend to assume 32bit more often than not).
I'll be running just a standard setup of PHP 5, MySQL 5, and Apache 2, powering several moderate-traffic sites that run on the Drupal CMS (e.g. about 7000-10000 visitors per day total, though hopefully more in the future of course). I don't plan on running a control panel other than Webmin, though I might get DirectAdmin or similar in the future to make hosting some friends/clients a bit simpler.
Will going with 64bit offer any worthwhile advantage with this setup?
RHEL 5 - 32bit V 64bit Running Cpanel 11 For Hosting
Jul 8, 2008As cPanel is an integral part of server hosting and has the ability of compiling Apache 1.3.x with PHP4 (cgi) and PHP5 (dso) on your server OS.
Does anyone know or have baselines/benchmarks for which performs better generally for hosting: 32bit or 64bit RedHat 5 when cPanel 11 has compiled for the Apache and php mentioned above on either of these OS editions? (assume latest versions of apache/php4/5)
I was wondering if 32bit performed better or 64bit on a quad core Xeon. Don't forget PHP is compiled for prefork and not multi-threading for Apache 1.3.41 (which are considered legacy 32bit forked apps compiled against 64bit OS).
Or rephrased, could i be hampering performance by running it on a 64bit OS on a Xeon (X3210) or improving performance? I'd assume 64bit would offer better all round processing power, or is this a misconception.
I recently decided to get a server on RedHat Enterprise 5 X86_64 (64bit), when i wondered if 32bit version would have provided better performance and been the better options for compatibility.

How Do I Host Windows 2008 Server As A Guest OS On My Linux Dedi
Apr 26, 2009How 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.
KVM Hypervisor And Guest OS Setup
Mar 15, 2009I 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.
32 Bit Xen Guest On X86_64 EL5 Node
Oct 18, 2009Let'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?

VMWare - WinXP As Guest On CENTOS - Networking
Sep 8, 2007OKay 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?
Xen Update, On Bringing Guest Networks Back Up
Jul 16, 2008After 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.
MS Virtual PC - How To Access My Localhost (Apache) Subdomains On Guest OS?
Mar 23, 2007I'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 -
