How reproducible:

Steps to Reproduce:
1.Install xen on tyan 2462, 2 scsi, 2 ide scsi and 2 ide cd's
2.Try to start vm

Actual Results:  VFS: Cannot open root device

Expected Results:  The vm should have found one of the drives.

Additional info:


I have had simillar issues in the past with anaconda on this box as well, I need to get a new drive soon anyway, when I get it I will try to test with only 1 scsi drive.

I rebuilt the xend package using the spec file and patch from the rpm and the
tar ball at xen-source it plays nicer now.
I had to make a few changes in the %files section of the spec file some chnages.

Any explanation for the non dev crowd for this?

Upstream xen-unstable is very aptly named.  It looks like there's always
something broken, and always something else ;(

Any time I resync to a different upstream Xen snapshot I'm essentially playing
russian roulette ;)

I will hit the xen-devel list for now, their is way too many things going on for
one bug report in bugzilla. If I get a build that plays nice on my SMP FC4 will

More recent xen changeset's are behaving much better.
