Hi there,
I'm having a problem with 9p virtfs mounts going away when I savevm,
quit, then restart with -loadvm. The mount seems to cause the guest
kernel to hang if I interact with it in any way that causes a stat(2).
I'm also unable to mount a 9p filesystem after a snapshot restart.
Is this expected, or should they work? I'm using qemu version 0.14.50,
and this happens at least with kernel versions 2.6.32 and 2.6.38 in a
Debian Squeeze guest.
Thanks,

virtio-9p doesn't currently support savevm which means it doesn't work
with migration or savevm/loadvm.

Ah, thanks. Is that a "can never work with the current implementation,"
or "can work but nobody's got round to it yet"?
