Re: [Xen-users] DomU pygrub issue - OSS Xen to XCP
George
Thanks for quick response, have you successfully installed grub on such kind of my domU and bootup into OS?
Seems it doesn't' work for me to install pygrub according to this wiki
http://wiki.xen.org/wiki/PyGrub
Any ideas?

You have no bootloader and what how you expect virtual machine to
boot?
Chroot to domU filesystem, install grub. Or use
PV-kernel/PV-ramdisk/PV-args variables to boot kernel from 'outside'
domU (they must resides in /boot/guest of XCP dom0).

Thanks for your response , since this domU copied from dom0 and
has no a grub on it, although I give other try to installed
kernel-xen and grub manually on OSS Xen Host, which still being
stuck to start up.Do I need fix the grub installation first on OSS
Xen Host and then start migration ?
With many thanks

Also
if you can please post your menu.lst or grub.cfg from
the domU.
Post all PV fields of VM (xe
vm-list params and copypaste all fields with PV in
name). Looks like you having bad settings for
PV-bootloader(-args).

Hi, All
I'm just new to this list, I'm
started to dealing with OSS Xen to XCP migration
earlier this week, seem the domUs installed via
virt-install are function well,
but domUs copied via dom0 are
failed during bootup process, finally I realize
if I could fix this on my OSS Xen will resolve
all.
Can
I have any suggestion from you please ?
