Apparently newer versions of QEMU refuse to live migrate if you're using caching, unless you force it with the unsafe command-line flag. We need to:
1) look into whether that really is unsafe for us (ie, does it do a cache flush or a sync).
2) Find out if we can make it work without making the user provide the unsafe option.

This is a libvirt problem, it's not related to qemu at all. I already looked into and tested whether qemu was doing flushes correctly (see #2467).
