Libvirt Hosts

What are the Libvirt Hosts?​

Libvirt Hosts inform the VM scheduler about available resources on the host.

note
  • Static address translation allows you to input NAT settings such as an IPv4 address and a NAT port base.
  • You can only edit the name of your host.
  • States provide a flexible architecture for managing Libvirt hosts and their Virtual Machines.
  • You can check the resource utilization used by the host.

What is the Difference Between Disabled, NoSchedule, and Enabled Host State?​

  • NoSchedule: The VM Controller has contact with the Libvirt host. The Libvirt host is probably already running some VMs, but the VM Controller instructs the VM Scheduler not to run any new VMs on it and to keep things as they are.
  • Disabled: The Libvirt host is completely off and is not running anything at the moment.
  • Enabled: The Libvirt host is running normally.
note

The NoSchedule state is used when you want to limit the VM resources on a Libvirt host to a certain extent.

What is the Difference Between True vs. False Connected Libvirt Hosts?​

  • True Connected means you are connected to the Libvirt host and can communicate with it.
  • False Connected means you are not connected to the Libvirt host. This indicates a communication issue with the VM host, and you need to fix the connection.
