[one-users] Live migrate failed and VM is lost

[Himanshu Khona]

All -I tried to run livemigrate and the VM itself disappeared.
I know the issue but it seems something like this should be immediately
fixed as a bug or stated as pre-requisite.
The target system on which I was moving the VM had its root mounted on a
logical volume whereas the one on which VM was running it was mounted on
/dev/sda3

Here is the xend.log from the target system -
[2008-12-01 13:49:59 xend 2759] DEBUG (blkif:24) exception looking up device
number for sda3: [Errno 2] No such file or directory: '/dev/sda3'

Here is the snippet of the vm.log -
tail -f vm.log
