Listing all virtual machines | LinuC Level 1 101 Exam original practice question

1.01.2Basic

List all libvirt domains, including inactive ones.

Which command is appropriate?

Hint 1: Focus on the requirement

Find the listing option that broadens the default active-only view to include inactive definitions.

Hint 2: Key terms

Review the short definitions before comparing the virtualization or lifecycle choices.

--all: A virsh list option that includes active and inactive domains.
Inactive domain: A defined virtual-machine object that is not currently running.
Persistent definition: A domain configuration retained by libvirt across a stop and later start.

Correctvirsh list --all

Correct. virsh list --all includes inactive domains.

Incorrectvirsh net-list --all

Foundation review

An inactive domain can still have a persistent definition even though it has no running process or active ID.

Confirm the domain state and name with a full listing before starting, undefining, or deleting anything.
