1. Connect to the hypervisor:

   • virsh -c <URI>: Connect to the specified Hypervisor, such as  virsh -c qemu:///system connecting to the local QEMU/KVM Hypervisor.

2. Virtual machine management:

   • list: List all virtual machines.
   • start <domain>: Start the virtual machine.
   • shutdown <domain>: Shut down the virtual machine gracefully.
   • destroy <domain>: Forcibly shut down the virtual machine.
   • autostart <domain>: Set the virtual machine to start automatically.
   • undefine <domain>: Deletes the definition of the virtual machine (does not delete the disk).
   • define <XML file>: Define and create a virtual machine.
   • edit <domain>: Edit the virtual machine configuration.

3. Virtual machine information:

   • dominfo <domain>: Display the basic information of the virtual machine.
   • domstate <domain>: Displays the status of the virtual machine.
   • vcpuinfo <domain>: Displays the CPU information of the virtual machine.
   • domblklist <domain>: Display the disk information of the virtual machine.
   • domiflist <domain>: Displays the network interface information of the virtual machine.

4. Snapshot management:

   • snapshot-create <domain> <snapshot name>: Create a snapshot of the virtual machine.
   • snapshot-list <domain>: List the snapshots of the virtual machine.
   • snapshot-revert <domain> <snapshot name>: Restore the virtual machine to the specified snapshot state.
