Subject KVM qcow2 perfomance
Date Sat, 05 Aug 2017 15:22:28 GMT
Hi everyone,

I'm having trouble to archive a good I/O rate using cloudstack qcow2 with any type of caching
(or even disabled).

We have some RAID-5e SSD arrays which give us a very good rates directly on the node/host,
but on the guest the speed is terrible.

Does anyone knows a solution/workaround for this? I never used qcow (only raw+lvm) so I don't
know much to do to solve this.

Thanks!
