Default incusbr0 seems to be capped at 8 leases?

IncusOS
1

Hi, second post here. I’m trying to add an 8th container to my IncusOS system. So far, they’ve all been on incusbr0, and it assigns each of them an IPv4 through DHCP.

incusbr0 currently has 8 leases on it: 7 containers and the gateway lease (incusbr0.gw). I just added an 8th container, and for some reason, no matter how hard I try, I can’t get it to lease an IP from incusbr0??

I’ve tried re-creating the container, using a different name, making sure the settings are correct, and it still won’t work.

Any help would be greatly appreciated. With my luck, it’s something stupidly simple that I’m totally missing.

Hey :slight_smile:

Please give the output of incus network show incusbr0 as well as incus network list.

Hmm nothing obvious, try something like

incus network set ipv4.dhcp.ranges=10.242.58.2-10.242.58.254

Please also give incus version

Not running into this problem here. I just used a clean IncusOS system from our demo (try-it) service and ran 50 Debian 13 containers on it using the default incusbr0:

bash-5.2# for i in $(seq -w 50); do incus launch images:debian/13 c$i; done
bash-5.2# incus list -fcsv -cn4

Is macvlan use an issue?

I thought about that as well I don’t think incusbr0 is bridged to enp42s0

EDIT: No “parent enp42s0” that means it is bridged @perfectkirkle ?
