I have several xen domu's running in LVM partitions on the local hard
drive. I have added a USB drive and tried to boot a domu from it but
it failed. I assumed it was a SCSI device name conflict so I created
a LVM on the USB drive but there is still a kernel panic:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)
My config:
 1 name = "samba"
 2 kernel = "/boot/xen-linux-2.6.12.6-xen"
 3 root = "/dev/sda1 ro"
 4 memory = 128
 5 disk = 
[ 
'phy:/dev/mapper/vgusb-guest.samba,sda1,w','phy:/dev/mapper/vgusb-guest.samba.swap,sda2,w'
 ]
 6 vif = [ 'bridge=xenbr0', 'bridge=xenbr1' ]
 7 extra = "3"
What can I do to get a domu running from a USB drive?
I can indeed mount /dev/mapper/vgusb-guest.samba manually.
The internal hard drives are two SCSI software mirrored RAID1.
David
