Hi Jaime,

Thank you for the patch.

It all went good and I launched the second VM. Error I mentioned was due to
VNC configuration on VM template. I have used the same VNC port for second
VM.

TM_LVM works fine now and it creates the LV with VMID.

I have another doubt, how can I force to create  on the fly SWAP and other
disks to be  on LVM.

Once again thanks for the help.

Thanks,
Anoop
