[libvirt] [tck PATCH] network tests: change network address to avoid commonly-used subnet
by Laine Stump
My own machine has a virtual network on 192.168.123.0/24, and I've
been told that it's a common selection for people who create a second
network after libvirt's default (and in the past was used as a manual
alternative for the default network itself when 192.168.122.0/24
casued a conflict). Changing to 192.168.97.0/24 also isn't foolproof,
but it's much less likely to encounter a conflict leading to a failed
test.

[libvirt] [tck PATCH] scripts: shorten netdev/domain name to prevent overflow
by Laine Stump
When new pids are more than 9 digits long
The nwfilter tests use tck-test${pid} as the auto-generated name for
their test domains (and therefore the tap devices created for those
test domains). When the pid is > 9 digits long, the total length of
the name is > 16, which is the maximum length for any network device
name (IFNAMSIZ), and this causes failure to create the tap device,
thus failure of the test:
/home/laine/devel/libvirt-tck/scripts/nwfilter/050-apply-verify-host.t ..
error: Failed to start domain tck-test10513851
error: Network interface name 'tck-test10513851' is too long:
Numerical result out of range
The solution is to just remove "test" from the name template, so pid
can be up to 12 digits long before the test fails.

[libvirt] [PATCH] qemu: Fix segmentation fault on reconnect
by Marc Hartmayer
On start up of libvirtd the worker pool of the QEMU driver must be
initialized before trying to reconnect to all the running QEMU
instances. Otherwise segmentation faults can occur if there are QEMU
monitor events emitted.
