When I try to install Virtulizor on the server, ipv6 becomes unavailable.
Just like This:
PING google.com(dfw28s23-in-x0e.1e100.net (2607:f8b0:4000:817::200e)) 56 data bytes
From server (2610:150:8000:db::44:55) icmp_seq=1 Destination unreachable: Address unreachable
However, it is available before installation, and I had checked the ifcfg-eth0 didnt have any change at all...
I have tried many times but still the same problem, wish you can help me, thank you a lot.
Virtualizor creates a bridge(viifbr0) using virtnetwork service.
What you can do is create a permanent bridge, as per this guide, with ipv4 and ipv6 in it and avoid virtnetwork service and then check :
