Red Hat Bugzilla – Bug 182722
Create VMX domain will crash and reboot Service OS.
Last modified: 2007-11-30 17:11:25 EST
Description of problem:
I have installed FC5-test3 IA32 system in my Presler (It has Intel 845
mainboard.) I can create XenU successfully.
But when I try to create VMX (HVM) guests, whole system (Domain0) will crash and
reboot. I also try the latest RPMs from development tree. It also failed.
With following config in grub.conf, I can capture serial output when crashing.
title Fedora Core 5 Test3
kernel /boot/xen.gz-2.6.15-1.1975_FC5 dom0_mem=262144 com0=115200,8n1
module /boot/vmlinuz-2.6.15-1.1975_FC5hypervisor ro root=/dev/sda1
console=ttyS0 console=tty0 pci=noapci
I will paste the serial output to attachment.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install FC5-Test3 with Xen.
2. Xend start.
3. Modify HVM config file and prepare VMX disk image.
4. Create VMX domain. Whole system rebooted.
Reboot OS when create VMX.
VMX domain can be created.
Need special serial port config to get serial output like the grub.conf

The serial out put of create VMX failure
This is the same instabilities that were in upstream Xen for HVM when we pulled
our snapshot. It should be fixed in the newer snapshot we're trying to pull in
Okay. Could you please let me know, when you integrate the new version? Then I
can check it.
This bug likely was fixed before FC5. Closing
