3 years ago LXD does not configure your system's DNS to hit LXD's dnsmasq so this can't really be a LXD bug.
I'd recommend asking at https://discuss.linuxcontainers.org instead for such support and integration questions.
I suspect you'll want to at least show your resolved config.

search lxd@stgraber this issue was reported back is 2018, shame LXD/XLC hasn't resolved it completely: https://github.com/lxc/lxd/issues/4337

3 years ago @krzysztofp that won't work as you want, because the first IP may give an answer (even a negative one) which will stop the resolver trying the LXD bridge resolver.
