New subject: [libvirt] [PATCH 1/2] rpc: Actually increase reference count on @srv in virNetDaemonAddServer
VIR_APPEND_ELEMENT would clear @srv to NULL after it successfully
inserted it thus the reference count could not be increased afterwards.
Switch to VIR_APPEND_ELEMENT_COPY. This fixes crash after terminating
the daemon.

New subject: [libvirt] [PATCH 2/2] daemon: Add the admin service to the admin server only if it was allocated
If the admin service is disabled it would not be allocated, but the NULL
pointer still would be added to the admin server. Since
virNetServerAddService would dereference it, the daemon would crash.
Move the service registration into the block that allocates it.

ACK series. Funny, I was just about to send the 1/2 patch too.
