After upgrading from Debian Stretch to Buster, I notice DHCP no longer offers leases for containers. After struggling for a couple days, I’ve finally decided to give up => Downgrade to Stretch.

I’ve read some of you manage to run LXD on Buster host.
Did you get also some issues about DNSMASQ dhcp ?

I don’t know if it’s related but my server is running on OVH (might be a kernel issue), and vanilla kernel does not seem to be supported so far.
Meanwhile, I try running from VirtualBox and it was OK. So it could be related to OVH.

Any help would be appreciated.

Definitely, this is an issue due to OVH => no relationship with lxd/lxc.
Sorry for disturbing.

I’ve dist-upgraded from stretch to Buster, then rebooted.
No more ICMP packets, no more DNSMASQ DHCPOFFER.
I guess the latest kernel (Buster) does not work properly onto OVH machine yet.
