Thanks for testing!


- live migration

A is the source host, B is the destination host, 'test' is the vdi name of Sheepdog:

1. Start the VM on A

 $ qemu sheepdog:test

2. Start the VM on B with '-incoming' option

 $ qemu sheepdog:test -incoming tcp:0:4444

3. Do migration in the qemu monitor on A

 (qemu) migrate -d tcp:B:4444

- run VMs outside the cluster

A is one of the Sheepdog nodes, 'test' is the vdi name of Sheepdog.
Then run:

 $ qemu sheepdog:A:7000:test

'7000' is a port number the sheep daemon uses.

This syntax would be changed in future, because the host A can be a
single point of failure.  I think of passing multiple hosts through
environment variables like RDB.


Thanks,
