4:51 p.m.
I have many boxes running rh-7.2
(these are stripped down, minimal installs, for appliances on a private
network that isn't routable) I want to run VIRTUAL images of the
same setup for testing purposes.
I read the Fedora 6 XEN getting started guide and skimmed through the
FAQ. I browsed through this mailing list to see if I could find my
problem here as well. No luck.
I have a Dell-2950 with Quad Core XEON processors, PAE, VMX, and it is
enabled in BIOS. 8GB RAM, 2GB assigned to Dom0
Booted into RHEL-5 Xen kernel, installed all the latest patches as of
6/11/2007, and rebooted.
Then Started Virtual Machine Manager GUI
Selected "New..." from File menu and followed the wizard.
then installed FULLY VIRTUALIZED
RH-72 from original Red Hat 7.2 CD's
this went fine with the
Virtual Machine Manager GUI "New Machine" wizard.
The only non-usual thing I did for an RH72 install was
to give it the kernel boot option mem=500M
After the install completed, the DomU guest said it was now going to
reboot and I should remove any CD's.
Then the DomU disappeared.
It took me forever to figure out that I couldn't use the virt-manager
GUI to restore a DomU configuration file. There really should be
a more intuitive way for this to work. I am not a dummy, and it took
me forever to figure out how to start the DomU again.
Now that I figured out that I have to go to a command line prompt and
type "xm create -c /etc/xen/rh72-test",
I find out that the new guest gets a kernel panic on bootup
after the bootup menu
Unfortunately the messages scroll by really fast, and I can't catch
them all, but at the end, the last page visible in the VNC console
says:

Any ideas?
I would have thought that a fully virtualized host would be pretty
foolproof?

I read the Fedora 6 XEN getting started guide and skimmed through the
FAQ. I browsed through this mailing list to see if I could find my
problem here as well. No luck.
I have a Dell-2950 with Quad Core XEON processors, PAE, VMX, and it is
enabled in BIOS. 8GB RAM, 2GB assigned to Dom0
Booted into RHEL-5 Xen kernel, installed all the latest patches as of
6/11/2007, and rebooted.
Then Started Virtual Machine Manager GUI
Selected "New..." from File menu and followed the wizard.
then installed FULLY VIRTUALIZED
RH-72 from original Red Hat 7.2 CD's
this went fine with the
Virtual Machine Manager GUI "New Machine" wizard.
The only non-usual thing I did for an RH72 install was
to give it the kernel boot option mem=500M
After the install completed, the DomU guest said it was now going to
reboot and I should remove any CD's.
Then the DomU disappeared.
It took me forever to figure out that I couldn't use the virt-manager
GUI to restore a DomU configuration file. There really should be
a more intuitive way for this to work. I am not a dummy, and it took
me forever to figure out how to start the DomU again.
The virt-manager release in Fedora 7 can now start existing inactive
guests. We recently pushed an update to Fedora 6 updates-testing
which can do the same.
Now that I figured out that I have to go to a command line prompt
and
type "xm create -c /etc/xen/rh72-test",
That is no longer neccessary. Virt-manager can do that. You can also
do it with 'virsh' which is the preferred tool for command line usage
virsh start rh72-test

Thanks Dan, that helps. I'm glad the Virt-Manager GUI is being updated.

The virtual machine kernel is the one panicking.
Do you think anybody is going to care about a RH7.2 kernel panic?
Nobody will care, right?
They would close the BZ report just saying it is old, unsupported
in this configuration (running that old 7.2 kernel in a Xen environment).
Isn't "fully-virtualized" Xen supposed to be able to run any
i386 system that can utilize the virtual hardware presented?

I find out that the new guest gets a kernel panic on bootup
after the bootup menu
I found out that if I add the kernel option "nomxt" to the
grub.conf kernel command for the DomU it gets much farther
in the boot process.
Now I get this on the console:

Now I get this on the console:

Then it hangs right there.
I give up. Looks like running fully virtualized old versions
of Linux just isn't going to work smoothly.
I'm going to use VMware ESX server instead.
