Manage CPU and Memory Resources for LXD Linux VMs

In this video, we explore how you can allocate CPU and memory resources to virtual machines running with LXD under Linux. Since LXD version 5.8 (November 2022), you can hot-plug CPUs from virtual machines, both adding and removing. As of today, memory cannot be hot-added to LXD virtual machines; you must shutdown the VM before adding memory, otherwise you'll receive an error. The "lxc config" command gives you direct control over the number of CPU cores and RAM allocated to each LXD virtual machine.

As a bonus, we also take a look at LXD nested virtualization in action. You can run LXD virtual machines on top of other LXD virtual machines, providing flexibility over how you deploy infrastructure.

Quick Summary
--------------------------

➡️ LXD supports hot-plugging CPUs
➡️ LXD does NOT support hot-plugging memory
➡️ LXD supports nested virtualization
➡️ The "lxc config" command can change VM or LXD daemon settings
