Central storage (e.g. Ceph) would allow for improved migrations and failover scenario's.39 votes
Having done some experiments and seeing that NVMe is becoming the storage platform of the future I would like to request that you allow none LVM based storage for KVM.
RAW seems to perform some 30 - 40% better than logical volumes on raid NVMe, this may be due to some bottle neck or limitation with logical volume based block devices but the results are fairly consistent and from reboot to all guests booted RAW out performs LVM by closer to 60%
In simple terms this just means updating the config file the point at the raw or qcow2 image.15 votes
