xenstore should not be restarted. If it is restarted watches are lost,
and several key components like kernel backend drivers will cease to
work.

Qemu when launched with -nographic and -monitor screws the console
badly. Use nohup to prevent that.

Next version (4.2) is scheduled to be released very soon
if everything goes ok. This is a very close rc,
which we can start testing until 4.2 comes out.

Otherwise screen -x will not work without manually setting screen dir
|
|
|
|
|
|
|
| |
We need wait til the detatched screen has created the connection
sockets before trying to set the opts to it.
