[libvirt-users] virsh reboot problem

I am trying to reboot my virtual machines, running virsh reboot. Then I get the following error: error: this function is not supported by the connection driver: virDomainReboot Searching around I get the impression this should be fixed by now, since the bugs I find are old and resolved. These are the versions I'm running. Linux 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue May 10 15:42:40 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux libvirt-0.8.7-18.el6.x86_64 qemu-kvm-0.12.1.2-2.160.el6.x86_64 I also have acpid in both the host and the guest. Am I missing something? Thanks. /andreas
