These sometimes result in data corruption on the receiving end. It only happens if the VM is actually doing I/O (doesn't have to be all that much to trigger the issue). + +We use logical volumes and each VM has two disks. We use cache=none for all VM disks. + +All guests use virtio (a mix of various Linux distro's and Windows 2008R2). + +We currently have two stacks in use and have seen the issue on both of them: + +Fedora - qemu-kvm 0.13 +Scientific Linux 6.2 (RHEL derived) - qemu-kvm package 0.12.1.2 + +Even though we don't run the most recent versions of KVM I highly suspect this issue is still unreported and that filing a bug is therefore appropriate.
