Hi there. I'm experiencing bad performance on every I/O intensive action, such as clone a VM or when the guest updates packages via apt. I'm using a Directory pool [1] with qcow2 files since I like the ability to perform snapshots. Reading some literature looks like a Filesystem pool [2] plus raw disk images is the best combination in terms of disk performance. Can somebody please confirm or contradict? Thanks Javier [1] http://libvirt.org/storage.html#StorageBackendDir [2] http://libvirt.org/storage.html#StorageBackendFS -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
