changing guest CD
Does KVM support changing the CD in a running guest's disc drive? I've tried to do it using the qemu monitor, but so far haven't been able to. I've seen rumor and innuendo that KVM can't change the disc in a running system, but no official confirmation yet.
If KVM doesn't support changing the disc in a running system, what would be required to support it?

It does via the change command. What did you try and how did it fail?

I've been using both libvirt and raw qemu monitor with Fedora 11 KVM RPMs. After further testing, while F11 doesn't work, F10 does. Guess it's time to see if Fedora bugzilla already has a report.
