Now the init script is called xencommons and, as the name suggests, it is a common script between xl and xend because it is used to start xenconsoled, xenstored and xenbackendd and the initialization of these three daemons has been removed from xend. The global xen_toolstack=xl/xend variable has been removed. Regarding the network setup, I made the vif scripts follow the same pattern as the other scripts in xen-backend: a new script called vif-setup is executed unconditionally. vif-setup is going to do the right thing depending on the value of the environmental variable "script" (same technique used before), defaulting to vif-bridge. In the common scenario the toolstack doesn't need to set the variable "script" because vif-bridge is going to be called anyway. There is no global network script to setup the network bridges with xl, so if you are using xl without xend, you need to manually configure the bridges using your distro network setup, or, if you are lazy, you can just add something like: /etc/xen/scripts/network-bridge start to your rc.local.

"""Xen management daemon.
|
|
Provides console server and HTTP management api.
|
|
|
|
Run:
|
|
xend start
|
|
|
|
Restart:
|
|
xend restart
|
|
|
|
The daemon is stopped with:
|
|
xend stop
|
|
|
|
The daemon should reconnect to device control interfaces
|
|
and recover its state when restarted.
|
|
|
|
On Solaris, the daemons are SMF managed, and you should not attempt
|
|
to start xend by hand.
