So can we please get the detailed setup where this happens, that is: filesystem used in the guest any volume manager / software raid used in the guest kernel version in the guest image format used qemu command line including caching mode, using ide/scsi/virtio, etc qemu/kvm version filesystem used in the host any volume manager / software raid used in the host kernel version in the host > Avi's patch is a performance optimization, not a correctness issue? It could actually minimally degrade performace. For the existing filesystems as upper layer it doesn not improve correctness either. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
