Re: Bad Disk Performance of domU

 Thanks all of you. Just with the nonsparse option works all right. 

 Then an LVM+nonsparse+phy will be the better setup?

Dom0.  After you pvcreate, vgcreate, and lvcreate (or whatever you need to do), use something like this in your VM's config:

disk = [ "phy:/dev/XenVolGroup123/foovm456,xvda,w" ]

If you decide that you prefer the LV setup, you can migrate from your sparse file to a new LV with fdisk, kpartx, and dd.
