Hi,
I've a question on whether it's 'safe' to change the socket type
used in virNetxxx calls from AF_PACKET to AF_LOCAL ?
The reason I ask is that we're using libvirt-lxc with a couple of
bridge interfaces, and we've found that the socket close call on
AF_PACKET type sockets takes between 40ms and 60ms. For our container
config there is roughly 12 close calls on AF_PACKET sockets, delaying
the start-up of the LXC container by around 450ms.
So a simple fix to speed up our container start-up is to just
switch from AF_PACKET to AF_LOCAL sockets. Hence my question on whether
we can safely do this, or is there some reason why AF_PACKET was chosen ?
Thanks in advance,
Ben.
FWIW - I believe that AF_PACKET sockets take so long to close is because
the kernel packet driver calls synchronize_net() when closing.
