Hello
I'm running yesterday's unstable installation tarball on top of FC4 and
I'm running into a problem when I reboot a guest. When the guest tries
to come back up it's unable to find sda1. Here's the configuration file
kernel="/boot/vmlinuz-2.6-xenU"
memory="128"
name="web"
nics=1
disk=['phy:mapper/XenVolume-lvol3,sda1,w',
'phy:mapper/XenVolume-lvol4,sda2,w']
root="/dev/sda1 ro"
And here's the output from the console.
