Support for a network such as -N dhcp,source=default was not working
in that dhclient was not being started. Although I am not sure what
the real problem is, the solution is to use g_spawn_sync() instead of
g_spawn_async() to start /sbin/dhclient.
The second patch addes "-v" to the dhclient arguments to improve debugging
info. The dhclient into will be in /var/log/messages the Secure Contrainer
host system and not in the container itself.

for dhclient use g_spawn_sync instead of g_spawn_async
add -v to dhclient parameter arguments

New subject: [libvirt] [PATCH 1/2] for dhclient use g_spawn_sync instead of g_spawn_async
For some (unknown) reason, g_spawn_async() is not starting dhclient
so that a dhcp NIC can be configured. However, simply using
g_spawn_sync() works. This was the only use of g_spawn_async().
Note: There is no problem using sync instead of async since dhclient will
disconnect and put itself in the background once the network is started.

Given the file you are patching, it might help to do:
git config format.subjectprefix 'sandbox PATCH'
so that it is obvious this is a different repo than the normal libvirt.git.
