Sorry to reply to my own post, but still not making any progress with
this. Here's my domU config file which is working with pyGrub.
# -*- mode: python; -*-
name = "testvm"
vcpus = 1
memory = 1024
maxmem = 1024
# pygrub
bootloader = "/usr/bin/pygrub"
# end pygrub
# pvgrub
#kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz"
#extra = "(hd0,0)/boot/grub/menu.lst"
#end pvgrub
dhcp = "dhcp"
disk = [ "phy:/dev/VolGroupVM/testvm,xvda,w",
"phy:/dev/VolGroupVM/testvm-swap,xvdb,w" ]
vif = [
"mac=00:16:3e:00:00:12,ip=192.168.1.12,bridge=xenbr0,vifname=viftestvm" ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
If I remove the pygrub bootloader line and un-comment the pvgrub entries I
always end up at the 'grubdom>' prompt. If I then enter 'configfile =
(hd0,0)/boot/grub/mennu.lst' pvgrub works and I can boot the domU
successfully.
I'd be really grateful if anyone can offer any advice?
Thanks in advance,
Matt.
