Re: [Xen-users] mount: unknown filesystem type 'devfs'

Eernesto,

I'm using lvm2 volumes , on debian sarge, in all domU's. No problem with 
that. You might want to check out your xen-dom1.cf again.
Your root entry points to /dev/sda2 but you are exporting sda1 to your 
domU. Also make sure your /etc/fstab in the domU is correct.
I think yous should have something like this in xen-dom1.cf

kernel = "/boot/vmlinuz-2.6.12-xenU"
ramdisk = "/boot/initrd.img-2.6.12-xenU"
disk = [ 'phy:data/Dom1-root,sda1,w' ]
root = "/dev/sda1 ro"
extra = "4"

and  in /etc/fstab in the domU something like

/dev/sda1     /     ext3     errors=remount-ro   0     1

Regards,
Jan-Petter ::-Q
