Hi all,
Sorry if this is not really a Xen problem, but it is something which you
wouldn''t want to do if you were not playing with virtual machines...
I had one small VM set up to use as a base for other (paravirtualized)
VM''s.
(both dom0 and the domU''s in question are Fedora Core 6 installs).
I gave it a LV, say /dev/VG_domU/base, as its (only) disk /dev/xvda, and
partitioned it during install as follows:
/dev/xvda1 /boot filesystem
/dev/xvda2 PV for VG VG_base, with LV''s
swap for swap
root as / filesystem
which is the way I usually partition my Linux installs (except that I
usually create LV''s for /usr, /var, /tmp, /home etc.)
Then in dom0, I created another LV /dev/VG_domU/derived, did a dd from
/dev/VG_domU/base to /dev/VG_domU/derived, et voila, I have another VM.
But this other VM has on its disk a VG with the same name, so I wanted to
rename the VG: you never know if you want to access both VG''s at the
same
time.
So I used kpartx to make it visible:
# kpartx -a /dev/VG_domU/derived
# vgscan
# vgrename /dev/VG_base /VG_derived
Then, of course, the name of the VG are mentioned a number of times:
- in /boot/grub/grub.conf the name of the root partition
- in /etc/fstab
- and in /init on /boot/initrd...img
But after that, the cloned VM with the renamed VG wouldn''t boot -
kernel
panic.
Does someone has an idea what I''m missing here?
Greetings,
Daniel
