Hello list.

I just tried pvgrub with a single-partition host:
kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz"
extra = "(hd0,0)/boot/grub/menu.lst"
root = "/dev/sda1 ro"
extra = "xencons=tty console=tty"
memory = 512
maxmem = 1024
name = "cendrillon"
uuid = "46b9ff12-7ceb-4139-bbff-47117e650f25"
disk = [ 'phy:/dev/iscsi/sn.101200926/lun9/part1,sda1,w' ]
vif = [ 'mac=00:16:3e:00:00:1a, bridge=hebergement' ]

However, it can't read menu.lst file. And any attempt to load itinteractively fails:

grubdom> configfile (hd0,0)/boot/grub/menu.lst


Error 5: Partition table invalid or corrupt

The messages seems to imply pvgrub expect to read a partition table,meaning a whole disk has to be exported to the virtual host, and not asingle partition ?
