Hi!
You have some typos that do not help in understanding the issue.
- What is
VMS? What do the letters stand for? - This is an LXD question, you can tag it as LXD. In one case you mention by mistake
lxcbr0, though you probably meantlxdbr0.
Your LXD configuration uses a private bridge, which means that the containers by default will use LXD’s internal dnsmasq DHCP/DNS server.
If you want your containers to use the network’s DHCP/DNS server, you need to either setup a bridge or macvlan. macvlan would be easier, see The LXD tutorials of Simos on how to set either.
