Wow. That's been the exact opposite of my experience in RHEL. Xen is
lightning fast, especially if you install the guest OS to a raw
partition (i.e. /dev/sdb1) or to an LVM slice (i.e.
/dev/mapper/XenVol-Node01). It's silly fast, quick to install guests,
and easy as all get-out to spin up guests as needed.
