Xen users - Jul 2008 - QCOW - good choice?

Hi,

I want to ask if anyone of you is familiar with QCOW and has used this 
with xen?

I''ve googled a bit about and could''nt really find out if
it''s a good
choice or not.
Has anyone experience with usage in xen and can say something about 
performance
and snapshot usability?

Thanks in advance,
Alex

If you have the money to buy an extra machine, install OpenSolaris on it 
and set up a nice ZFS with iSCSI setup... your performance would 
probably be 10x better :)

If you don''t have the money, it is the poor mans solution to use 
propriatary xen-qcow and achieve 3.0MB/s with a if=/dev/zero of=/swap :)
