Question 1

What is the main purpose of VM operations?

Answer 1

To understand VM runtime states, manage virtual disk image files, and ensure safe administration and efficient storage handling.

Question 2

Answer 2

They reflect the current activity of a virtual machine and determine which administrative actions are allowed.

Question 3

The VM is active and using system resources.

Question 5

What does the ‘paused’ state mean?

The VM is temporarily halted without shutting down.

Question 6

What does the ‘shut off’ state mean?

Answer 6

The VM is powered down but retains configuration and disk data.

Question 7

What does the ‘suspended’ state mean?

Answer 7

Memory contents are saved to disk for later resumption.

Question 8

What does the ‘crashed’ state indicate?

Answer 8

System failure due to error or misconfiguration.

Question 9

Which tool is commonly used to monitor and manage VM states?

Answer 9

Tools like virsh are used to monitor and manage VM states.

Question 10

Which administrative actions often require a shut off or paused state?

Answer 10

Disk resizing or hardware modification.

Question 11

What is a disk image in virtualization?

Answer 11

A disk image is a file acting as the VM’s virtual hard drive, storing OS, applications, and user data.

Question 12

Name common disk image operations.

Answer 12

Format conversion, resizing, inspecting properties.

Question 13

Give an example of format conversion.

Answer 13

Convert QCOW2 to RAW for compatibility or performance.

Question 14

What does resizing a disk image do?

Answer 14

It increases storage capacity for the VM; VM must be shut off before resizing and guest OS may require partition and filesystem adjustment.

Question 15

What does inspecting disk image properties display?

Answer 15

Format type, virtual size, actual usage, and backing files.

Question 16

What does disk image management support?

Answer 16

VM migration, environment consolidation, storage planning, disaster recovery.

Question 17
