These are some questions that are frequently asked about LXD and related technologies.
- Can I use storage backend other then directory, that doesn't support some features?
This could be circumvented by using a image file and formatting it with btrfs and using that as storage pool.
- I can see all 80 cores with lscpu, are they all available?
No, unfortunately you can use only the number of cores that you have paid with your subscription.
