Problems creating vm alpine, with cloud-init password

LXD
1

Hello!! to all
I am trying to create an alpinelinux virtual machine with LXD VM, but I have not been successful
with the configuration of the user and the password (Cloud-init) sentenced in the created profile.
The debian-based machines with the steps indicated here https://cloudinit.readthedocs.io/en/latest/topics/examples.html that are the same as the one used in my alpine profile run without problems, but in alpine and others distro not based on debian there are problems.
I think it could be the kind of algorithm that alpine uses.
any suggestion.
I have also used this configuration, only successfully on debian-based distro.

Which image did you use to launch the VM?

3

alpine edge for vm

4

Can you give me the specific launch/init command you used please

5

lxc init images:alpine/edge vm-edge -p vm-edge -s local --vm

6

That wont have cloud init in it, you need to use images:alpine/edge/cloud I think.

Although I don’t know if that image exists yet. @monstermunchkin do we have an alpine cloud image?

7

Use this image from alpine vm, and no more images

Alpine traditionally did not have the cloud-init package.
When LXD got /cloud container/VM images, there was such an image for Alpine but obviously could not work due to the absence of that package. And that container image/vm image for Alpine was removed.

However, in Alpine 3.13, Alpine got support for cloud-init.
Therefore, use version 3.13. There are /cloud packages for that.

We have a cloud-init VM for Alpine Linux 3.13. However, I don’t see why we shouldn’t have one for edge as well.

I tested the image in cloud 13 which leaving the following errors

I’ll look into that.

@darmon77 what LXD version are you using? I cannot reproduce your error on the master branch.

This is what I get:

4.9

14

What distribution are you using?

15

voidlinux

16

OK, thanks. It looks like your system is unable to use virtiofs which is fine. In that case it’ll try to use 9p as a fallback which doesn’t seem to work for some odd reason. That might be a problem with our images though. I’m currently looking into that.

17

virtiofs is present in the kenerl of voidlinux

18

When starting the VM, is virtiofsd running as well? That’s needed for virtiofs to work. It should be part of qemu.

19

@monstermunchkin with the alpine vm image it does not start virtiofs, with other images such as debian ubuntu it starts without problems.

20

I tried with LXD 4.9 using virtiofs and 9p. Both work fine.

Looking at the provided log again, you seem to be missing /run/lxd_config/drive/lxd-agent inside of the VM. I don’t know why though. If you’re running the snap, lxd-agent should be in /var/snap/lxd/common/lxd/virtual-machines/<vm-name>/config/.
