Description Paul Batkowski 2010-05-07 19:06:00 UTC

serial console output showing the kernel boot and panic.

Description of problem:

When doing an initial boot of anaconda to start a RHEL 6 beta 1 install inside of KVM, the guest encounters a kernel panic early on which prevents installation of RHEL 6 beta 1.

Version-Release number of selected component (if applicable):

  Host (x86_64):
  - RHEL 5.5 + errata
  - kernel-2.6.18-194.3.1.el5
  - libvirt-0.6.3-33.el5
  - kvm-83-164.el5

  Guest (x86_64):
  - RHEL 6.0 beta 1
  - kernel-2.6.32-21.el6

How reproducible:

Every single boot attempt.

Steps to Reproduce:
1. Boot guest with 512MB of RAM (tried up to 2GB) using local iso file (RHEL6.0-20100420.n.0-Server-x86_64-DVD1.iso)
2. Select the first option in the bootloader: "Install or Upgrade an Existing System"
3. Watch the kernel boot up and fail.
Actual results:

Kernel boots and shortly after encounters an oops and a kernel panic, preventing the install.

Kernel panic - not syncing: Fatal exception

serial console of boot output from rhel 6 beta snap 1

Just tried with snap 1, which includes kernel-2.6.32-22.el6 and encountered the same issue which is preventing the install of RHEL 6 beta as a KVM guest running on a RHEL 5.5 host. Attaching capture of boot from serial console.

Comment 6 Amit Shah 2010-05-13 15:41:26 UTC
Can you test with 1G of guest RAM?

Comment 7 Paul Batkowski 2010-05-13 15:58:06 UTC
As originally posted, I already tried with up to 2GB for guest memory set and still this issue reproduces 100% of the time.

Comment 8 Marcelo Tosatti 2010-05-17 02:21:18 UTC
The patch on bz #574621 should fix this, marking as a duplicate.

I don't know whether that patch is already part of an official update, apparently not.
