That would be the easiest way.

and the image.

disk = ['phy:/dev/VolGroup01/vmsname,hda1,w',
'phy:/dev/VolGroup01/vmsname,hda2,w' ]

So in your original setup, the file is mapped as hda while in LVM
setup each LV is mapped as partition (hda1, hda2)?


When i try to create the vms it hangs until I control+c it. Anyone have
any insight? Thanks in advance.

Does "pygrub /dev/VolGroup01/vmsname" work? It should give the similar
output as when you run "pygrub /path/to/your/original/image/file.img".
Also please check whether udev is running (ps -ef | grep udev).

After sending the original thread off to the ML I had tried the 'dd' method and it worked flawlessly. My only concern is being able to resize the filesystem inside of the images after i've dd'd them over. it should be just like resizing any other logical volume with a resizable file system...all ext3 centos vms' so i would imagine this will be fine? Any caveats from anyone?
