PXE boot failing on LXD VM's

Using the LXD Server installed by MaaS (and upgrade lxd to version 5.21), the VM’s are not able to find the DHCP server.

A part of vm console log from lxd:

lxc console worthy-marmot  --project maas 
To detach from the console, press: <ctrl>+a q
: Server response timeout.

So, any idea?

Hi @vasartori
What version of MAAS are you using?
Is DHCP service is up and running?

Also could be a network issue?

hi @troyanov
We are using the latest version of MaaS, 3.4.1.

Yeah, the DHCP Server is OK, because we can deploy physical machines using maas.
BTW, the LXD server was deployed by maas.
The only thing I made on server, was update the LXD snap, due a bug with a version 5.20. I have updated to version 5.21/candidate.

Hi @vasartori ,

Verify that the networking is functional and that the container DHCP request can reach the network where the DHCPd is located (tcpdump is your friend).

Anyway, my experience is that using an LXD deployed and configured via MAAS never worked. But doing a manual LXD installation and hooking it to MaaS worked. Not sure where/why the automatic failed. My gut instinct is that the networking was messed up somehow.

In my case, I also use MaaS to deploy the host (22.04), but then a manual installation of LXD is needed.

Hi @pal-arlos

Good to known this (never worked on an automatic install).
I’ll try to do a manual installation of LXD and see what happens :slight_smile:

When I have some spare time, I’ll test it out.

@pal-arlos To save time on research and avoid unreliable installation guides.

Do you have any installation guide for the LXD server that you can share?

Hej,

Think it was dead simple;
snap install lxd

Then follow the instructions in the MaaS UI, “Add LXD”.
