qcow2 performance
...W2003-VM within KVM.
Right now it's a qcow2-image-file w/ default settings within libvirt
(configured by vmm ...)
My question:
what caching to use?
writeback/writethrough/etc ... what to use for data integrity while not
getting ultraslow performance?
Found

Is there any other list/doc what to use and why?
Thanks, Stefan
