Description of problem: I'm trying to install a RHEL 6.0 guest from the DVD, on a RHEL 6.0 host (installed from the same ISO burned to DVD). However the guest kernel panics very early on: it cannot mount the ISO root filesystem. Version-Release number of selected component (if applicable): On host: qemu-kvm-0.12.1.2-2.113.el6.x86_64 seabios-0.5.1-3.el6.x86_64 kernel-2.6.32-71.el6.x86_64 libvirt-0.8.1-27.el6.x86_64 python-virtinst-0.500.3-7.el6.noarch Linux kempei-rhel6.home.annexia.org 2.6.32-71.el6.x86_64 #1 SMP Wed Sep 1 01:33:01 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux Guest: RHEL6.0-20100922.1-Server-x86_64-DVD1.iso How reproducible: 100% Steps to Reproduce: 1. Download RHEL6.0-20100922.1-Server-x86_64-DVD1.iso 2. Create 10G LV for disk. 3. virt-install --accelerate -r 1300 -f /dev/vg_kempei/RHEL60x64 -n RHEL60x64 --cdrom /var/tmp/RHEL6.0-20100922.1-Server-x86_64-DVD1.iso Actual results: Guest kernel panics because it cannot mount root. See screenshot and transcription in comment 1. Expected results: Should not panic, should install. Additional info:

Additionally I have checked the MD5 of the ISO and it all appears to be correct.
As an additional data point, a Fedora guest is being installed from Fedora-14-x86_64-DVD.iso just fine on the same host.
Created attachment 475214 [details] Working RHEL 6.0 guest config generated by virt-manager As a point of comparison, this attachment is from a working RHEL 6.0 guest (on a RHEL 6.0 host), created and installed just now. It was generated using virt-manager rather than virt-install, so there might be some XML differences that could be the cause. (unsure)

The command line from the failed install doesn't correspond with the virt-install command line args shown. Can you run virt-install with --debug set and attach the output, along with the full QEMU log file libvirt creates.

Reassigning to kvm, probably isn't virtinst related. Rich, can you reproduce with just the qemu command line, or at least a pared down XML definition?
Can QE reproduce that? I wonder why it passes their tests.

As stated in comment 2, I checked the MD5 hash of the downloaded ISO and it appeared fine.
