[libvirt-users] VMware ESX 4.0 won't reboot guests.

Hi, I just compiled libvirt with ESX support. I can login just fine, list all the guests/domains but when I try to reboot or shutdown one of my guests/domains I get this error: virsh # reboot dbcluster1 error: Failed to reboot domain dbcluster1 error: internal error HTTP response code 500 for call to 'RebootGuest'. Fault: ServerFaultCode - fault.RestrictedVersion.summary And nothing happens. I'm logged in as root so it shouldn't be any permission-related problems right!? because I can reboot it just fine with the vSpehere Client on one of my Windows boxes. In vSpehere I see this in Recent Tasks after I execute the reboot command: Find entity by UUID I can't find anything about this on Google either. Does anyone know what's wrong here? Thanks, -Patric
