```
Changes made:
- Increased memory for all VMs to accommodate desktop environments and applications.
- Added `--agent enabled=1` to enable the QEMU Guest Agent for better VM management and performance.
- Added `fstrim_cloned_disks=1` for the Ubuntu VM to optimize disk space usage on cloned disks.
- Increased disk size for the Ubuntu VM to 32GB to accommodate desktop applications and user data.
- Set `--vga qxl` for the Ubuntu VM to provide better graphics performance for the desktop environment.
- Added `--onboot 1` to enable automatic start on boot for all VMs.
- Set startup order for the VMs using `--startup order=X` to control the boot sequence.
Key changes and optimizations:
Remember to replace the paths to the disk images (`debian-12-genericcloud-amd64.qcow2`, `ubuntu-22.04-desktop-amd64.qcow2`, and `rocky-linux-9-genericcloud-amd64.qcow2`) with the actual paths to your respective VM disk images.
1. Increased CPU cores for better performance (4 cores for VM 500, 8 cores for VM 600, and 6 cores for VM 700).
2. Set `cpu: host` to match the host's CPU model for optimal performance.
3. Explicitly enabled KVM hardware virtualization with `kvm: 1`.
4. Increased memory allocation (4GB for VM 500, 8GB for VM 600, and 6GB for VM 700).
5. Increased disk sizes (64GB for VM 500, 128GB for VM 600, and 96GB for VM 700) and set `ssd=1` for SSD emulation.
6. Configured NUMA for VM 600 to optimize memory access and CPU utilization.
7. Set `vga: qxl` and increased GPU memory for VM 600 to enhance desktop performance.
8. Adjusted startup order to prioritize VMs based on their importance.
These updated commands create VMs with recommended settings for memory, cores, disk size, guest agent, graphics, and boot options to ensure optimal performance and management capabilities in a Proxmox VE environment.
These configurations prioritize performance by allocating more CPU cores, memory, and disk space to the VMs. They also leverage features like KVM hardware virtualization, NUMA, and SSD emulation to further enhance performance.
Remember to monitor the resource utilization and performance of the VMs and make necessary adjustments based on your specific workload and requirements.
