I have been messing with QCOW on Xen and I''ve come to the conclusion
that
nobody actually uses it otherwise it would work. Has anyone gotten QCOW2 and
Xen to work reliably?
I have 40 PV VMs that are identical (initially) and would like to move from
separate disk images to one base image sitting in a ramdisk and the COW
images hosted on an iSCSI storage device. The VMs would boot off the base
image from ramdisk which should be very fast. Only when they would write to
disk would things slow down and go to the iSCSI RAID. This would allow boot
times to shrink and remove a lot of disk speed problems.
Has anyone done this or have any other ideas.
Grant
