You give very little information about your setup and the problem. - What kind of storage do you use? ( software or hardware raid? how many spindles? what kind of disks?) - Does it have battery backed cache? Is the battery on this cache OK? - How much IO, with how much latency, is generated on the hosts? ( run some diagnostics e.g. "iostat -mx 10" for a couple of minutes on a host ) - How much IO, with how much latency, is generated on the VMs? - Is IO on the host better than on the guest? How much? (test!) - What is the storage type of the storage domain? ( local FS? iSCSI? Fibre Channel? GlusterFS? ) - What type of IO controller do you use in the guest? ( IDE? virtio? virtio-scsi? ) - Do you use thin- or thick provisioned disks? - Do you use snapshots?
