+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.
+
+---
+
+Here's a guide to help you manage your VMs using the qm command-line tool in Proxmox VE:
+
+1. Creating a VM:
+   Use the `qm create` command to create a new VM. Specify the VM ID, OS type, disk size, and other parameters.
+   Example:
+   ```
+   qm create 100 --memory 1024 --net0 virtio,bridge=vmbr0 --bootdisk sata0 --ostype l26 --sockets 1 --cores 2 --sata0 local-lvm:32,format=qcow2
+   ```
+
+2. Configuring VM Hardware:
+   Use the `qm set` command to modify VM hardware settings such as CPU, memory, network, and disk.
+   Examples:
+   - Set CPU cores: `qm set 100 --cores 4`
+   - Set memory: `qm set 100 --memory 2048`
+   - Add a network device: `qm set 100 --net1 virtio,bridge=vmbr1`
+   - Add a disk: `qm set 100 --sata1 local-lvm:64,format=qcow2`
+
+3. Starting and Stopping VMs:
+   - Start a VM: `qm start 100`
+   - Stop a VM: `qm stop 100`
+   - Shutdown a VM gracefully: `qm shutdown 100`
+   - Reset a VM: `qm reset 100`
+
+4. Cloning and Templating:
+   - Clone a VM: `qm clone 100 101`
+   - Create a template from a VM: `qm template 100`
+   - Create a new VM from a template: `qm clone 100 102 --name "New VM"`
+
+5. Managing Snapshots:
+   - Create a snapshot: `qm snapshot 100 snap1`
+   - List snapshots: `qm listsnapshot 100`
+   - Restore a snapshot: `qm rollback 100 snap1`
+   - Delete a snapshot: `qm delsnapshot 100 snap1`
+
+6. Migrating VMs:
+   - Offline migration: `qm migrate 100 pve2 --online 0`
+   - Online migration: `qm migrate 100 pve2 --online 1`
+
+7. Backup and Restore:
+   - Backup a VM: `vzdump 100 --storage local --compress lzo`
+   - Restore a VM: `qmrestore 100 vzdump-qemu-100-2023_05_20-14_30_00.vma.lzo --storage local-lvm`
+
+8. Monitoring VM Performance:
+   - Show VM status: `qm status 100`
+   - Show VM configuration: `qm config 100`
+   - Show VM usage statistics: `qm monitor 100`
+
+9. Accessing VM Console:
+   - Access VM console: `qm terminal 100`
+
+10. Managing VM Disks:
+    - Move a VM disk to a different storage: `qm move-disk 100 scsi0 local-lvm`
+    - Resize a VM disk: `qm resize 100 scsi0 +10G`
+
+Remember to replace `100` with the actual VM ID you want to manage.
+
+These are just a few examples of what you can do with the `qm` command. For a complete list of available options and commands, refer to the qm manual page by running `man qm`.
+
+Always make sure to have proper backups of your VMs before performing any major operations. Regularly monitor your VMs' resource usage and performance to ensure optimal operation.
