Hey Vu,
What is the kernel you are using?
I had a kernel panic for xen - doing a yum update kernel-xen allowed to the
system to come online.
Regards, Joe

Message-ID: <4efa0f6e.20...@sivell.com>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
I have had this Dell server running Xen for a couple of years and
decided to move to KVM. After moving all the guests to another server, I
reboot this server using the non-Xen kernel and install KVM.
Duing the process of installing the first guest, the host server panics.
This happens three times in the same manner: after selecting the
installation media, which is a local ISO file of RHEL5.5, the gurst's
RHEL boot screen starts and loads files. Then boom, the console shows
the panic screen and the server hangs.
The server is RHEL5.7 and already yum updated.
Any advices is greatly appreciated.
Thanks,
Vu

bios settings? processor type? you're likely going from para to full
virtualization right?

All the scripts in /etc/cron.daily get run at 4:00. My question again
is, why, then, if *both* scripts run *every* day at 4:00, I suddenly get
a massive report from tripwire that virtually every executable file on
the system has a different checksum?
(Actually, I also run chkrootkit daily, also out of /etc/cron.daily; it,
too, suddenly gave me a batch of checksum errors on executables.)

This is a Dell server R710 with one Xeon E5620 processor. The
virtualization is set to on in the BIOS. This is the first guest on this
server and it is a full virtualization system.

chkrootkit doesn't calculate any checksums for executables.
Probably you refer to rkhunter instead.

Right, rkhunter is what I meant.

I don't have any suggestions as to the cause of the problem, but a
backtrace would likely be helpful. Easiest way is probably to configure
kdump:

The vmcore and sosreport have been sent to RH support. The panic screen
shows the functions related to the (kvm)bridge and bnx2 so we tested
installing a guest without using the bridge. It works !!! So the culprit
is either the br driver or the bnx2 driver. I am waiting for RH Support
to look at the vmcore. Also checked with Dell for the latest bnx2
driver, and Dell said RH has the latest one.
Anyone experiences this problem with the driver bnx2 or br?
Thanks,
Vu
