As a matter of fact, our servers are either Dell PowerEdge 1950/2950
and IBM xSeries.
I am just testing it out on our lab PC first.

Dear Boris,
My next step will be a 64-bit Xen Dom 0 host.

Teo, it is
up to you how to manage, if you just having fun.
Otherwise, downloading 64-bit OpenSuse 11.1 ISO image
takes just 12-14 hr even at slow ADSL speed ( like 100
KB/sec).
Install takes 30 minutes and brings you to the trusted
results, instead
of wasting a lot of time in case of business environment
assignment.
Pasi has 32-bit experience due to hardware limitations, which
you don't
have.
Boris.

Dear Boris,
My colleague installed OpenSUSE 11.1 32-bit on the Core 2
Duo machine in our labs. Please see my earlier replies in the same topic.
I was too lazy to reformat and install 64-bit OpenSUSE, so
I proceeded with Xen Dom 0 pvops kernel compilation on 32-bit Linux host.
I admit I am getting a lot of headache. Haha.

Once again, i don't see any reason to to run 32-bit OS on
Core2Duo,
unless you like Xen head ache. Core development
(PVOPS) is obviously
running in 64-bit environment.

Why it wouldn't ? If your image stays
the same.

That is not supposed to happen. I would
suggest clean OS (without any built in xen presence) install , followed
by Xen 3.4.1+pvops kernel clean install.
Boris.

Dear All,
I am very puzzled. In investigating the
cause of the sudden success of the CentOS 4.7 32-bit PV guest being able to
run, I have uninstalled virt-manager and all of its dependencies:
docbook
python-gtk-vnc
xen-libs 3.3.1
scrollkeeper
xen-tools 3.3.1
libvirt 0.4.6
libvirt-python
vm-install 0.3.24
Then I proceeded to "make uninstall" in
xen-3.4-testing source tree, which also removed my self compiled Xen Dom 0
pvops enabled kernel, initrd and kernel modules.
After doing the above, I re-installed
back the Xen hypervisor, libraries and tools, and also the kernel, initrd,
and modules. Then I proceeded to reboot my machine. After rebooting, my
CentOS 4.7 32-bit PV guest is still able to start and run!
I am still very puzzled! What causes the
PV guest initially cannot start? Then what subsequently causes the PV guest
to suddenly be able to start and run???
***scratches head***
Anyway my CentOS 4.7 guest domain is now
running. I shall now proceed to virtualize OpenSolaris 2009.06.
Thank you.
Also see screenshots of my CentOS 4.7 PV
guest here:

Unable to Configure Xen Dom 0 in Jeremy's PVOPS Kernel
Hi Pasi,
It's very strange. Suddenly my CentOS
4.7 32-bit PV guest is able to start!!! Previously it refuses to start at
all.
I think I must have changed something
in Dom 0 when I attempted "yast --install virt-manager". This action might
have solved the problem. When I tried to install virt-manager, it also tries
to install xen-libs-3.3.1 and xen-tools-3.3.1 as dependencies. However, I
started off my Xen Dom 0 pvops kernel install with Xen 3.4.1 rc8 branch.
I need to investigate more why suddenly
my CentOS 4.7 32-bit PV guest is able to start.

Unable to Configure Xen Dom 0 in Jeremy's PVOPS Kernel
Hi Pasi,
I realized that Fedora 10 32-bit
anaconda installer does not install PAE kernel after mounting the guest disk
image file. I mounted the guest disk image file using losetup and kpartx
which adds device nodes to /dev/mapper. I examined the /boot directory after
mounting the guest disk image file and found no PAE vmlinuz and initrd.
Still using the mounted Fedora 10
32-bit guest disk image file, I changed root to the guest disk filesystems
and attempted to install the PAE kernel. Then I modified menu.lst to boot
the PAE kernel. After modifying the grub configuration of the guest domain,
I un-mounted the guest filesystem.
I proceeded to boot the F10 32-bit
guest, since I changed to PAE kernel. It is able to boot now (since the PAE
kernel is xen-aware) but then it complains cannot mount /dev/root. Probably
something to do with the PAE initrd file.

Fedora 10 installer has a bug,
as a default it installs non-PAE kernel for
xen domU. You need to use a
kickstart script (like this) to fix it:
http://pasik.reaktio.net/fedora/f10-xen-domu-ks.cfg
The important lines being:
-kernel
kernel-PAE
(Fedora 10 and Fedora 11
default kernels are compiled with pv_ops Xen domU
support enabled, so there's no
need for separate kernel-xen with these distros).
Fedora 11 doesn't have that
installer bug, so it installs right
out-of-the-box as Xen domU.
What's the error you get when
you start the guest after installation?
Please paste the "xm log" as
text.
I don't have any problems with
CentOS 5.3 dom0.
