Yes, the problem is that the current code is passing an explicit
qemu:///system in to virConnectOpen, so libvirt's default logic
is being bypassed. If the SNMP agent just passed 'NULL' then libvirt
would auto-pick the hypervisor, and LIBVIRT_DEFAULT_URI would also
'just work'. So NACK to this patch, ust replace qemu:///system with
NULL.
