Re: [Xen-users] DomU pygrub issue - OSS Xen to XCP
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 ?
