Re: [CentOS-virt] 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?

Regards.

LVM on dom0 or domu?

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.
