Hello allz,
I'm using Xen 3.0.1 on an x86_64 and tried to export 2 logical volumes
from Dom0 to DomU as sda1 and sdb1, but DomU can't mount it.
If I change it to hda1/hdb1, it works very well. Does someone have an
idea what I could be missing?
Here's my DomU Xen Startup file:
--- snip ---
kernel = "/etc/xen/kernel/linux-2.6.12.6-xenU"
memory = 512
cpus = "" # leave to Xen to pick
name = "test1"
disk = [ 'phy:xen-volumes/test1-swap,sda1,w',
'phy:xen-volumes/test1,sdb1,w' ]
vif = [ 'bridge=xenbr0' ]
root = "/dev/sdb1 ro"
--- snap ---
Here are the kernel messages shown when trying to start my DomU:
--- snip ---

My DomU kernel has SCSI and SCSI disk support compiled in, so this
should not be the problem.
Cheers,
