What is the key difference between live migration and offline migration of a VM?

Live migration requires the VM to be shut down, while offline migration does not

Live migration moves a running VM without downtime, while offline migration requires the VM to be shut down

Offline migration is faster than live migration

Live migration is only possible within the same host, while offline migration can cross hosts

What is the primary goal of high availability (HA) in a virtualization environment?

To automatically restart VMs on another host if the original host fails

To migrate VMs between hosts without downtime

To provide backup and restore capabilities for VMs

To increase the performance of individual VMs

An admin needs to attach an existing disk image to a running VM as a secondary disk. The disk image is in qcow2 format. Which command should the admin use?

virsh attach-disk /path/to/disk.qcow2 vdb --live

virsh attach-device /path/to/disk.qcow2 --live

qemu-img attach /path/to/disk.qcow2 vdb

virsh add-disk /path/to/disk.qcow2 vdb
