RE: [Xen-users] Xen 3.0 domain creation issues on fc4

["James" <seven@xxxxxxxx>]

Thanks, /dev/mapper/vg-lvm1 is the LVM device, if the device is mounted the
create fails with the local device error. I ran the create command with out
the lvm info in fstab.  Same problem.

run this commands

1- umount  /dev/mapper/vg-lvm1
2- xm create -c vm01.cfg
3- and remove the parameter in fstab for lvm
