[Pkg-libvirt-maintainers] Bug#557744: libvirt-bin: Starting domain fails with "qemudOpenMonitorUnix: monitor socket did not show up.: Connection refused"

[Vadim Zeitlin]

Package: libvirt-bin
Version: 0.7.2-3
Severity: important


Running "virsh -c qemu:///system create vm.xml" fails with

	error: Failed to create domain from vm.xml
	error: monitor socket did not show up.: Connection refused

and

	kernel: [ 2863.481686] device vnet0 entered promiscuous mode
	kernel: [ 2863.483550] virbr0: topology change detected, propagating
	kernel: [ 2863.483555] virbr0: port 1(vnet0) entering forwarding state
	kernel: [ 2863.599974] virbr0: port 1(vnet0) entering disabled state
	kernel: [ 2863.630507] device vnet0 left promiscuous mode
	kernel: [ 2863.630513] virbr0: port 1(vnet0) entering disabled state
	libvirtd: 14:08:22.683: error : qemudOpenMonitorUnix:1007 : monitor socket did not show up.: Connection refused

in syslog. The symptoms are identical when running this command as a normal
user (member of libvirt group) or root.

Unfortunately I was unable to find out which socket it wants to connect to,
all I can say is that it is _not_ /var/run/libvirt/libvirt-sock as it does
connect to it successfully.

Looking at qemudOpenMonitorUnix() in libvirt Git it seems like the error is
indeed given from there but, mysteriously, I don't see these socket() and
connect() calls neither with strace nor gdb so I just don't understand
what's going on here at all. Any pointers in the right direction would be
appreciated.

Thanks in advance!
