Summary: Unable to boot dom0 - Kernel panic - not syncing: VFS:
Unable to mount root fs on unknown-block(2,0)
Product: Xen
Version: unstable
Platform: All
OS/Version: All
Status: NEW
Severity: blocker
Priority: P2
Component: Hypervisor
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: dbarrera@xxxxxxxxxx
CC: hohnbaum@xxxxxxxxxx,pl@xxxxxxxxxx
I am unable to boot dom0 on any on my machines today, using changeset 8729. This
is happening in both x86 and x86_64, SLES 9 and FC4 based platforms. I will pull
latest source and rebuild just in case it has already been fixed.
