Hi everyone
According to http://wiki.qemu.org/Migration/Storage section "Image
Formats" qemu can't do live migration without data corruption when using
qcow2 or qed due to the metadata caches.
Wasn't that fixed by commit 06d9260 ?
Also, "Clustered File Systems" does not seem to be up-to-date since
libvirt considers only OCFS and GFS2 to be safe for migration with
cache!=none. Since FUSE supports O_DIRECT officially, adding GlusterFS
to this list may be appropriate as well?
Thanks in advance,
Tiziano
