Re: [Xen-devel] pygrub: further improve grub2 support
I've tried to PV domU with ready HVM domU via profile:-
memory = 2048
name = "UbuntuLynx"
bootloader="/usr/local/bin/pygrub"
vcpus = 2
vif = [ 'bridge=eth0' ]
disk = [ 'phy:/dev/sda8,xvda,w']
vfb= ['type=vnc,vncunused=1']

In meantime i don't know. I will take a look at device.map a bit latter.
But , it doesn't look to myself as "beta" issue

So grub in Ubuntu 10.04 uses _Linux_ device naming in the bootloader
configuration? That seems like an awfully big break with tradition.
Do you know how grub2 tries to interpret this, perhaps using a
device.map type file in /boot/grub? Or perhaps it is simply a bug in
10.04 beta?
sda isn't really a valid name for a modern PV domU kernel anyway. It
should be xvda. Looks like you need to do some additional tailoring to
convert your HVM Ubuntu domain into a PV
one.
Ian.
