I have a CentOS 5.7 domU I''m trying to convert from an hvm to pv.
I''ve
installed the xen kernel in the domU and setup menu.lst and fstab for
xvda devices.
When I try to xm create the domU I get "Error: Boot loader didn''t
return
any data!"
If I do:
pygrub /dev/mapper/360030d90f890d704c735eff06069f0df
I get:
Traceback (most recent call last):
File "/usr/bin/pygrub", line 713, in <module>
chosencfg = run_grub(file, entry, fs, incfg["args"])
File "/usr/bin/pygrub", line 548, in run_grub
g = Grub(file, fs)
File "/usr/bin/pygrub", line 204, in __init__
self.read_config(file, fs)
File "/usr/bin/pygrub", line 408, in read_config
raise RuntimeError, "couldn''t find bootloader config file in
the
image provided."
RuntimeError: couldn''t find bootloader config file in the image
provided.
If I do:
pygrub /dev/mapper/360030d90f890d704c735eff06069f0df_part1
This one I see the grub menu.
The disk structure is:
part1 = /boot
part2 = swap
part3 = /
Any suggestions or thoughts on where the problem lies?
Thanks,
James

the default debian squeeze fs is ext4. If your /boot is ext4, back it up, and reformat as ext3. The pygrub in Centos won''t support ext4. -- Mark ________________________________ From: James Pifer <jep@obrien-pifer.com> To: Xen list <xen-users@lists.xensource.com> Cc: Alexandre Kouznetsov <alk@ondore.com> Sent: Thursday, April 12, 2012 10:49 AM Subject: Re: [Xen-users] pygrub question On Thu, 2012-04-12 at 12:34 -0500, Alexandre Kouznetsov wrote:> Hello. > > El 12/04/12 09:35, James Pifer escribió: > > When I try to xm create the domU I get "Error: Boot loader didn''t return > > any data!" > > In what order are the vitrual disks mentioned in your DomU .cfg file? > > Make sure your VM''s /boot goes first. >It''s one partitioned disk. /dev/mapper/360030d90f890d704c735eff06069f0df so: disk=[''phy:/dev/mapper/360030d90f890d704c735eff06069f0df,xvda,w''] Thanks, James _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
