Oh, you're using the old lxcbr0 bridge and yeah, it's got a 250 IPs limitation due to it being a /24.
So run: sudo dpkg-reconfigure -p medium lxd And answer the questions, giving it something bigger than a /24, probably a /16 and entering a matching number of max dhcp hosts, that should fix things for you. ** Changed in: lxd (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571862 Title: No IP is issued for more than 251 containers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1571862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
