VM doesn't boot when --raw = LVM volume

[Mikko Ohtamaa]

If you use --raw and LVM volume the virtual machine is created fine, but it doesn't boot.

Bochs BIOS screen says no harddisk is found.

More detailed info:

[moo@bison][21:43][~]% sudo lvcreate -L20G -n myvirtmachine vg01
  Incorrect metadata area header checksum
  Logical volume "myvirtmachine" created

sudo vmbuilder kvm ubuntu -v --hostname=harvinaiset --mem 512 --ip=xx.20.128.35 \
--mask 255.255.255.224 --net xx.20.128.32 --bcast xx.20.128.63 --gw xx.20.128.64
--user admin --pass adminpw --firstlogin=login.sh --raw=/dev/vg01/harvinaiset --addpkg acpid -o --flavour virtual --tmpfs - --libvirt qemu:///system

[18:27:43] <moo---> soren: http://pastebin.com/m3402df61
[18:27:52] <moo---> works fine if I remove --raw
[18:28:54] <soren> I don't see the error?
[18:30:51] <moo---> sorry, I need to rebuild vm
[18:31:00] -*- moo--- does not have the fastest horse on the market
[18:31:03] <soren> Oh, is this the UUID thing?
[18:31:44] <moo---> umm?
[18:31:50] <soren> Never mind.
[18:33:52] <zul> nijaba: that libc6-xen stuff can be fixed in the kernel
[18:34:14] <moo---> ok this time I get this error
[18:34:15] <moo---> http://pastebin.com/m450eb61c
[18:34:30] <moo---> but I assume there is just some existing files I need to purg
[18:36:36] <nijaba> moo---: are you doing a --user admin in the command line?
[18:37:12] <moo---> let me check
[18:37:19] <moo---> yes
[18:37:40] <nijaba> moo---: could you try changing it name to something else?
[18:37:59] <moo---> rerunning...
[18:38:04] -*- moo--- gets excited
[18:38:11] <moo---> if I get this working i am a happy camper
[18:38:40] -*- nijaba think we should check that. would really appreciate if moo could open a bug about the admin thing
[18:39:03] <nijaba> once it has been confirmed, obviously
[18:39:03] <moo---> I assumed it's a logical volume -> it will get formatted in any case -> there can't be existing data
[18:39:28] <nijaba> moo---: you assume right
