I want to give my clients access to their Xen domU consoles using VNC. This works great using vfb device configured as type=vnc.

However I have 2 problems:

• I can't figure out how I can add a vfb device to a running domain without restarting it (I have 100+ domU's I want to enable this on, and want to avoid restarting them all if possible)

I've never heard about vfb hotplug..

• Related, I can't figure out how I can change the VNC password without restarting the domU, as the password is specified in the vfb config.

Is what I am trying to do possible? How?

I wonder if the password is stored inside the qemu-dm process (vnc server), or in xenstore..

If it's in xenstore then it's easy to change it.
