+ * Set the cpu_shares (priority) of the running VM. This is necessary
because the priority is only calculated when deploying the VM.
+ * When the number of cores and/or speed of the CPU is changed the
cpu_shares is only updated if the VM is restarted or manually, using the
command schedinfo.
Review comment:
It can be manually updated through the command mentioned in the PR
description: `virsh schedinfo --domain <vm_internal_name> --live
cpu_shares=<cpu_shares_value>` or restarting the VM. But I understand it is a
bit confusing the way it is written, I will rewrite it.
