'xm sysrq s' is not giving you a consistent disk image, because between the time you issue that command, and the time you save the disk/vm more I/O could have been issued. Ultimately if you want consistent disk images, you either need to stop the VM, and clne the disk. Or save the VM state to a file, and then clone the disk. Or use a 'vm snapshot' capability which does those two operations in one (which potentially allows for live snapshotting, which a 2-step process would not). We don't yet support the latter, but you can do save/restore of the VM state to a file, and snapshot the disk at that time.
