I am using two different IPv6 addresses for the two different machines.
I am unable to ping outside from the VM or connect otherwise via IPv6
from the VM. I am also unable to ping the link-local addresses of the
eth1 interface on the VM (via `ping6 fe80::5054:aaff:fe00:f057/64`).
ip -6 nei on the VM gives me:
`fe80::5054:ff:fe1d:a4bb dev eth1 lladdr 52:54:00:1d:a4:bb router STALE`
Hi,
Your setup shows
virbr2 and br0 both on the same network 2607:5300:60:1156::2/64 which
will cause issues with routing. This however must not affect the pinging
of link-local addresses
ON the virtual machine:
ping -I <eth0> <link-local of server>
must work.
If not
check both side link-local addresses if they are set.
A quick way to check with "any-body on the segment please reply" is to
on virtual machine
ping6 -I <eth0> ff02::1
You must see 2 addresses (one is your own link-local and the other is
the address on the server)
Example in my case is pasted (there are 4 machines):
$ ping6 -I n1 ff02::1
PING ff02::1(ff02::1) from fe80::2c3b:53ff:fea0:9d26 n1: 56 data bytes

If link-local address cannot be ping-ed then try pinging ::1.
