I'm having quite an interesting time getting up to speed with KVM/QEMU and the various ways of creating virtual Guest VMs. But disk I/O performance remains a bit of a question mark for me. I'm looking for suggestions and opinions ....
It's possible to set up guests to use a block device that will get you the same disk I/O as the underlying storage.
Is that what you're seeing? What speed does the host see when benchmarking the RAID volumes, and what speeds do the guests see?
