CV0-004 Troubleshooting Practice Question
Network Topology
A cloud administrator sees the output above when troubleshooting a virtual machine that is unresponsive. The VM is critical and must be restored quickly. What should the administrator do first?
⚠ Common exam trap
A common mix-up: candidates assume a paused VM requires a full restart or host-level intervention, but the CV0-004 exam expects you to recognize that `virsh resume` is the immediate, low-risk recovery action for a paused domain.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Resume the VM using the virsh resume command.
The output from `virsh list --all` shows the VM is in a 'paused' state, which means it is still resident in memory but not executing. The fastest way to restore a paused VM is to resume it with `virsh resume <vm-name>`, which immediately continues CPU execution without requiring a reboot or migration. This directly addresses the unresponsive behavior while preserving the VM's current memory state.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Resume the VM using the virsh resume command.
Why this is correct
This directly addresses the paused state and will restore the VM to a running state.
- ✗
Restart the libvirtd service on the host.
Why it's wrong here
Restarting libvirtd might affect other VMs and is not the direct fix for a paused VM; the VM state persists in libvirt's configuration.
- ✗
Increase the memory allocation for the host to free resources.
Why it's wrong here
There is no evidence that the VM paused due to memory pressure; increasing host memory is not a targeted solution and may require a reboot.
- ✗
Migrate the VM to another host in the cluster.
Why it's wrong here
Migration requires the VM to be running; a paused VM cannot be migrated without first resuming it.
