Thanks Jaime.

I have edited the  tm_lvmrc and now I get this error on launching a second
VM:

Tue Feb 22 08:51:33 2011 [LCM][I]: New VM state is BOOT
Tue Feb 22 08:51:33 2011 [VMM][I]: Generating deployment file:
/opt/cloud/one/var/87/deployment.0
Tue Feb 22 08:53:21 2011 [VMM][I]: Command execution fail: 'if [ -x
"/var/tmp/one/vmm/xen/deploy" ]; then /var/tmp/one/vmm/xen/deploy
/opt/cloud/one/var//87/images/deployment.0;
else                              exit 42; fi'
Tue Feb 22 08:53:21 2011 [VMM][I]: STDERR follows.
Tue Feb 22 08:53:21 2011 [VMM][I]: Error: Device 0 (vkbd) could not be
connected. Hotplug scripts not working.
Tue Feb 22 08:53:21 2011 [VMM][I]: ExitCode: 1
Tue Feb 22 08:53:21 2011 [VMM][E]: Error deploying virtual machine: Error:
Device 0 (vkbd) could not be connected. Hotplug scripts not working.


To test everything from scratch I have deleted the first VM and trying it
again.

Thanks,
Anoop
