Waydroid: Failed session start

LXC

I am using LXC container to start waydroid, but when starting it says it has failed:

waydroid log:

I’m not familiar with waydroid so can’t comment on what it’s doing or why.

But the error here is that it’s asking LXC to set up some CPU limits and your kernel doesn’t support those particular limits. It could be that the limits are specified for cgroup1 when you’re running cgroup2 or that your system just doesn’t have the correct cgroup support built in.

For this issue with Waydroid you would likely need to contact their support group. It’s on Telegram.

Mention which version of Waydroid you are using. This one, or Waydroid-Linux beta.

$ waydroid --version
1.4.2
$

I use Waydroid and it works fine, however when I run lxc-ls I do not see the Waydroid container in the list. Most likely it’s a separate setup from the system’s LXC.
