It doesn't work on my test. I tried start linux-0.2.img stored in sheepdog
cluster and then
1. did some buffered writes
2. restart sheep that this QEMU VM connected to.
3. $ sync
I got following error:
$ ../qemu/x86_64-softmmu/qemu-system-x86_64 --enable-kvm -m 1024 -hda sheepdog:test
qemu-system-x86_64: failed to get the header, Resource temporarily unavailable
qemu-system-x86_64: Failed to connect to socket: Connection refused
qemu-system-x86_64: Failed to connect to socket: Connection refused

qemu-system-x86_64: Failed to connect to socket: Connection refused
qemu-system-x86_64: Failed to connect to socket: Connection refused
...repeat...
QEMU version is master tip
Thanks
