That makes sense, particularly since I didn't understand that the vmware-
tools was something that runs on the guest-os.

So far I have gotten as far as getting the basics configured
including the network interface and have it automatically booting
when the Linux box comes up (although it's currently hanging
waiting for date entry which may require a bit of hackery).

The only way I have found to reliably get mouse and keyboard
focus out of the virtual window is to use ctrl-alt-F1 to switch
to a character mode, then ctrl-alt-F7 to get back to X11.

Tony Lawrence has some useful information for those of use who
are afflicted with maintaining SCO OpenServer systems:

VMware is pretty simple: download the server rpm, install it, run the

access the console where you can create and start the virtual machines.

As I mentioned in the post above, I prefer to connect directly to the

For me I like the features that Xen provides like hot-add
memory/processor/storage, live migration, etc. Though if you are not
using the commercial version you are kind of limited to the command
line for management, if that bother's you then maybe VMware more
suites your taste.

Oh, both products can host multiple Windows and Linux VMs side-by-side
no problem.

I haven't used xen so I can't compare them, but it is easy with vmware 
server and doesn't require any changes on the host other than installing 
the vmware package and configuring it.  People running xen tend to say 
that you shouldn't run anything else directly on the host, but this 
isn't a problem with vmware.

Yes, 32-bit PVM on 64-bit host has been supported since 3.1 I believe,
32-bit HVM on 64-bit host has been supported even longer.

On the 64-bit development system, get the base development system
installed with,

# yum groupinstall development-tools

Get the kernel-devel includes and configs installed and rpmbuild
installed along with the redhat standard rpm config,

# yum install kernel-devel rpm-build redhat-rpm-config

Install xen.org's SRPM,

# rpm -ivh xen-3.2.0-0xs.centos5.src.rpm

'cd' into /usr/src/redhat/SPECS and do a,

# rpmbuild -ba xen.spec

'rpmbuild' will tell you what else you need to install to get it to
build fully. Tex/LaTex/Texi are the largest requirements to build, and
only for the documentation part, so if you comment out the documentation
and remove those build requirements you could get by with less.

Yes, we do PXE installs with kickstart here for bare metal and virtual
servers and have our own in-house repository for things like this and
some other third party software that isn't part of CentOS and it has
cut time to deploy new servers down to about 5 minutes.

Subject: [CentOS] Xen or VMWARE on CentOS 5

Does anyone out there have a comprehensive tutorial on installing 
VMware and successfully managing virtual machines with either xen or 
vmware?






Hi Ross

I'm looking for the same thing, but you have "stirred" somethings up in me.

If I want to setup CentOS 5.1 64bit, and make it a XEN host, then 
install CentOS 5.0 / FreeBSD 6.0 / Fedora Core 7 32bit guests on it, 
would it work well?


And if you say it needs to be pre-compiled, can you please tell me howto 
do this? What / which files do I need, and how do I get them to work on 
a 64bit CentOS 5.1?
Currently I'm busy creating a custom installation CD for CentOS 5.1 
64bit, and would like to then include the re-compiled XEN components in 
my kickstart. The installation CD installs the bare minimum for CentOS 
to run as an OS, since we're using cPanel - which installs the rest

Re: [CentOS] Xen or VMWARE on CentOS 5

I'm not a big fan of Redhat's version of Xen and use the Xen 3.2 packages from 
xen.org as it has better management features through 'xm'. You will need to 
compile your own for 64-bit though as they only provide 32-bit binaries by 
default and if you want to run Xen as a hosting server you really must use 
64-bit, but thankfully they provide the SRPM for it which makes that trivial.

As far as VMware goes. It works exactly as it does on Redhat Enterprise Linux, 
so if you go over to the VMware forums and search RHEL, those comments should 
apply equally well to CentOS.
