Yep, this is a known issue: http://www.redhat.com/archives/libvir-list/2008-October/msg00168.html Moving to upstream bugtracker
Comment 2 Mark McLoughlin 2009-05-11 06:02:12 EDT
Ryan Harper posted a patch to add the qemu side of this: http://lists.gnu.org/archive/html/qemu-devel/2009-05/msg00450.html
Comment 3 Mark McLoughlin 2009-06-03 12:45:01 EDT
Okay, moving back to Fedora/rawhide and putting on F12VirtTarget

Comment 5 Mark McLoughlin 2009-08-07 07:36:28 EDT
AFAICT, the conclusion from upstream was that libvirt should do system_powerdown followed by polling via info status followed by system_reset

Any update on the status of this bug? The discussion on the Ubuntu dupe  of this bug has been lively, lately. We're curious if libvirt might simply implement "reboot" by sending "ctrl-alt-delete" to the guest. It seems that most Linux and Windows operating systems will handle ctrl-alt-delete as a warm reboot fairly consistently.

Comment 9 Daniel Berrange 2010-04-28 09:13:01 EDT
I most/many Windows, Ctrl-Alt-Delete is a shortcut to bring up the login dialog, not reboot, so its not really viable.
Comment 10 Dustin Kirkland 2010-04-28 10:20:47 EDT
Bummer. I guess it's really been that long since I used Windows. I swear ctrl-alt-delete used to reboot Windows...
Comment 11 Daniel Berrange 2010-04-28 10:27:20 EDT
Win 3.1 & Win 95/98/XP derivatives treat it as a reboot. Win NT and 2k, 2k3, 2k8, Vista, 7, derivatives treat it as a logon signal. http://en.wikipedia.org/wiki/Control-Alt-Delete#Windows

commit 42f43592be3045bed5dabdaea65718f6d2c706e4 Author: Daniel P. Berrange <firstname.lastname@example.org> Date: Wed Jun 15 17:49:58 2011 +0100 Support reboots with the QEMU driver For controlled shutdown we issue a 'system_powerdown' command to the QEMU monitor. This triggers an ACPI event which (most) guest OS wire up to a controlled shutdown. There is no equiv ACPI event to trigger a controlled reboot. This patch attempts to fake a reboot.
