• Format: QCOW2 is the industry standard for KVM environments. It supports sparse files (allocating space on demand) and snapshots.
• Performance: QCOW2 offers good performance and flexibility, though raw images sometimes offer slightly better I/O performance. However, QCOW2 is preferred for "new" deployments due to its snapshot capabilities.
• Portability: High. This image is portable across different storage backends supported by QEMU.

Instruction Counting:

Each vCPU now maintains its own instruction counter, allowing for more accurate "instruction-time" precision across parallel cores. Key Advantages PAVM-KVM-8

One of the most common maintenance tasks is expanding a disk. If your VM named pavmkvm801 is running out of space, you can expand the image file. Format: QCOW2 is the industry standard for KVM environments
