[libvirt] virsh reboot not working with QEMU driver?
I've noticed when using the QEMU driver that virsh reboot is not supported. Can this be supported, or is there some functionality that the underlying QEMU is missing?

Which version of libvirt and qemu? There has been some progress made on this front lately, and the most likely answer is that you are using older versions where it was not yet supported. Also, it may depend on whether your guest OS is responsive to ACPI commands. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

I'm particularly concerned with RHEL5, which uses an ancient version of both (I know that libvirt is 0.6.3, not sure about QEMU off the top of my head). But the same thing is happening on my Fedora 13 machine, which is using: # qemu-kvm --version QEMU PC emulator version 0.12.3 (qemu-kvm-0.12.3), Copyright (c) 2003-2008 Fabrice Bellard # rpm -q libvirt libvirt-0.8.2-1.fc13.x86_64 The guests respond to ACPI, since 'virsh shutdown' works as intended in them.

Just tested on Fedora 14, and it's still not directly supported in # rpm -q libvirt qemu qemu-kvm libvirt-0.8.3-2.fc14.x86_64 qemu-0.13.0-1.fc14.x86_64 qemu-kvm-0.13.0-1.fc14.x86_64 And virt-manager is still faking it with a shutdown, wait for event, and fresh boot. -- Eric Blake eblake@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org

IMHO, it's still in the TOBO list. :-) - Osier
