Comment 4 Juan Quintela 2010-12-01 02:34:10 UTC 
what type of disk is that?
iSCSI/Fiber channel?

file=/dev/mike/install08,media=disk,if=virtio,cache=none,boot=on,format=raw,werror=stop

?

We have a problem with flushing the read cache for this, there is the start of a patch, but I haven't finished it.
