What is the purpose of VM management?
Supports efficient deployment and maintenance of virtual machines. Key techniques include image templates, cloning, snapshots, and migrations. Ensures consistency, scalability, high availability, and operational flexibility.
What are baseline image templates?
Pre-configured VM images with OS, common software, and settings. Used as a master copy for new VM deployments.
Why are baseline image templates important?
They save time and ensure consistency in large-scale environments.
Name common formats for baseline image templates.
QCOW2, VMDK, VDI.
What metadata do baseline templates include?
System configurations and compliance details.
What is cloning in VM management?
Cloning duplicates an existing VM including disk image and settings.
Why is cloning used?
Creates identical VMs quickly for web servers or test systems. Also used for disaster recovery, training, and production replication.
What is often the source for cloning?
A baseline template.
Can cloned VMs be customized?
Yes, post-cloning customization for hostname or role is possible.
What is a snapshot in VM management?
A snapshot captures the full VM state including disk, memory, and configuration.
When are snapshots typically used?
Before major changes or testing to enable rollback if updates fail.
What does a snapshot include?
CPU, RAM, and network settings for full restoration.
Are snapshots a replacement for backups?
No, they are a short-term recovery method.
Why should snapshots be cleaned up regularly?
To reduce disk usage and prevent slowdowns.
What is migration in VM management?
Migration moves VMs between physical hosts.
Name the two types of migration.
Cold migration and live migration.
What is cold migration?
Performed while VM is powered off. Safe method for moving inactive systems.
What is live migration?
Moves running VMs with minimal downtime. Transfers memory, CPU, and I/O in real time.
What does live migration require?
Shared storage and compatible host systems.
Why is live migration used?
For load balancing, maintenance, and hardware failure resolution.
