Hi,
Multiple monitor instances would be very useful anyway.
Right now there is no way to use the monitor for libvirt-managed qemu
instances because libvirt uses the monitor. Being able to both use
libvirt *and* have a monitor prompt to type commands would be great.
I disagree - that means you'll no longer be able to trust what libvirt
tells you about the VM, and libvirt won't have a guarenteed consistent
view of the VM's state because things will be changed behind its back.
A nice side effect of having multiple monitors is that you can implement
a proper 'select' command. This command would block and tell you about
asynchronous events (like guest CD-ROM ejecting). You could use this
mechanism to notify libvirt when things changed because of other
monitors too.
It's more work though from a libvirt perspective and you probably don't
want users screwing around in the monitor anyway.
