I have in mind some high database load, like 5000iops or more, so it need a fast backup storage in this case. Such tests would be very useful - maybe you can run a few tests with that workload? Yes, sure, I'll do tests. Also another question, what happen is the backup storage goes down

How can i test? Command line qm command? # git clone git://git.qemu-project.org/qemu.git then apply the patches. # cd qemu # ./configure --target-list=x86_64-softmmu # make You can then start qemu with something like that: # ./x86_64-softmmu/qemu-system-x86_64 -monitor stdio
