Fair enough. Any idea if the 'system_reboot' command is also wired up in KVM yet ? We should probably just add code to call it anyway since it'll be near identical code to that which you used for shutdown, and its better than leaving domainReboot driver method as a no-op. There's no system_reboot in either kvm nor qemu. I see two solutions for wireing up domainReboot(). Either qemu/kvm accepts a parameter to system_powerdown to signal that we should restart the vm instead of simply shutting down or we simply send "sendkey ctrl-alt-delete" to the monitor which might be very fragile though. Both solutions depend on the os in the vm doing the right thing (acpi event handling in the first case).
Well there's a 'system_reset' monitor command, but its unclear if its actually working - when i run it, it stops the guest from responding to any keyboard input and makes it take 100% CPU, but doesn't reboot :-( If that's not suitable i think the ctrl-alt-delete thing is probably the best we can do.
You are quicker than me... With an up-to-date kvm, system_reset seems to be working fine (it was buggy in previous kvms). Dan.
