Hi,
 One of the OST suite (hc-basic-suite-4.3) is failing with error:   libvirtError: COMMAND_FAILED: INVALID_IPV: 'ipv6' is not a valid backend or is unavailable


Something like
echo 2 | sudo tee /proc/sys/net/ipv6/conf/enp0s31f6/accept_ra
on the server should fix the issue.
 
Full log:

Any one has idea what could be the issue?
