Occasionally I need to change the screen resolution of the console of a Windows virtual machine using XenCenter. When you attempt this change, Windows will revert if you don't accept the changed resolution within 15 seconds of clicking 'apply.' (Normally, this is a good thing.)

The problem is that if I have a slow connection between XenCenter and the Xen hypervisor, the virtual console display may not refresh quickly enough to allow me to respond within 15 seconds. As a result, I can't change the resolution, even though the new resolution is valid.

Is there a way to increase the timeout before reverting to the original display resolution?
