Hello,

I have a multinode set up with 1 compute and a controller node.

The issue i face is the internet from inside the VM does not work unless i manually add this rule to the IPTABLES -

iptables -t nat -A POSTROUTING -o br0 -j MASQUERADE

Although, one thing i did observe is that the net worked with ipv6 and not with ipv4!! Its strange coz i have actually disabled ipv6 on host and also added use_ipv6=False in nova.conf on compute node. adding the above rule enables ipv4 traffic too!

Its quite strange why this is happening!
