grub looks for vmlinuz and the kernel in /boot in the same partition.
your grub is configured to boot to (0,4) which is sda5
(0,0) would be the first partition of the first disk, or sda1.
So some wild guesses :
- check that /boot is on sda5
- check that there is a formatted partition on sda1
- assuming that you are using a typical MBR- partitioned disk, sda5
would be in an extended partition. It may be that xfs has problems
booting to extended partitions.
- maybe the dom0 means that it expects to put a file on the first
Is this partition big enough ? Or is 512k big enough ? Does it have
the right partition type ?
These are all wild guesses, as I'm not at familiar with Xen.
As Al13n says, we'd really appreciate you joining QA to test Xen for QA.
Or the packaging team to package Xen.
