[libvirt] [PATCH] Handle kernels with no ipv6 support
If the ipv6 kernel module is not loaded, then we get this when starting
a virtual network:
libvir: Network Config error :
cannot enable /proc/sys/net/ipv6/conf/virbr0/disable_ipv6:
No such file or directory
If disable_ipv6 is not present, we should just merrily continue on our
way.
* src/network_driver.c: make networkDisableIPV6() not fail if the kernel
has no ipv6 support
