Subject: [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
