1. Cluster Setup: Ensure that your Proxmox hosts are part of the same cluster. A Proxmox cluster consists of multiple Proxmox VE servers (nodes) combined to offer high availability and load balancing to virtual machines. Nodes in a cluster share resources such as storage and can migrate VMs between each other.
2. Shared Storage: Live migration requires shared storage accessible by both the source and target hosts. This shared storage can be implemented using technologies like NFS, iSCSI, or Ceph. Shared storage allows the VM’s disk images and configuration files to be accessed by any node in the cluster.
3. Migration Prerequisites: Before initiating a live migration, ensure that the target host has enough resources (CPU, memory, storage) to accommodate the migrating VM. Proxmox will check these prerequisites before allowing the migration to proceed.
4. Initiating Migration: In the Proxmox web interface (or using the Proxmox command-line interface), select the VM you want to migrate and choose the “Migrate” option. Proxmox will guide you through the migration process.
5. Migration Process:
   • Pre-Copy Phase: Proxmox starts by copying the memory pages of the VM from the source host to the target host. This is done iteratively, with the majority of memory pages copied in the initial phase.
   • Stopping Point: At a certain point during the migration, Proxmox determines a stopping point. This is the point at which the VM will be paused briefly to perform a final synchronization of memory pages and state information.
   • Pause and Synchronization: The VM is paused on the source host, and any remaining memory pages and state information are transferred to the target host. This pause is usually very brief, minimizing downtime.
   • Completion: Once the final synchronization is complete, the VM is resumed on the target host. From the perspective of the VM and its users, the migration is seamless, and the VM continues to run without interruption on the target host.
6. Post-Migration: After the migration is complete, the VM is running on the target host. You can verify this in the Proxmox web interface or using the command-line tools. The source host frees up resources previously used by the migrated VM.
7. High Availability (HA): In a Proxmox cluster with HA enabled, if a host fails, VMs running on that host can be automatically migrated to other hosts in the cluster, ensuring minimal downtime.

Overall, Proxmox VM live migration is a powerful feature that enables you to move virtual machines between hosts in a Proxmox cluster with minimal downtime, providing flexibility and high availability for your virtualized environment.

1. Cluster Configuration:
   • Nodes: A Proxmox cluster consists of multiple nodes, which are physical servers running Proxmox VE.
   • Networking: Nodes in a Proxmox cluster should be connected to a common network. A private network for internal communication and a public network for client access are typically configured.
   • Shared Storage: Shared storage is crucial for a Proxmox cluster to enable features like live migration and high availability. This can be achieved through technologies like NFS, iSCSI, or Ceph.
2. High Availability (HA):
   • Proxmox VE includes a feature called HA, which ensures that critical VMs are automatically restarted on another node in the event of a node failure.
   • HA relies on fencing mechanisms to isolate a failed node from the cluster and prevent split-brain scenarios. This can be achieved through power fencing (e.g., IPMI, iLO, iDRAC) or network fencing (e.g., switch port blocking).
   • When a node fails, the HA manager on the remaining nodes detects the failure and initiates the restart of the affected VMs on healthy nodes.
3. Corosync and Pacemaker:
   • Proxmox VE uses Corosync as the messaging layer and Pacemaker as the cluster resource manager. These components ensure that cluster nodes can communicate effectively and coordinate resource management.
   • Corosync provides a reliable communication channel between nodes, while Pacemaker manages the resources (VMs, containers, services) in the cluster and ensures they are highly available.
4. Resource Management:
   • Proxmox clusters allow for dynamic resource allocation, allowing VMs and containers to use resources based on demand.
   • Memory and CPU resources can be allocated and adjusted for each VM or container, and live migration allows these resources to be moved between nodes without downtime.
5. Backup and Restore:
   • Proxmox includes backup and restore functionality, allowing administrators to create scheduled backups of VMs and containers.
   • Backups can be stored locally or on remote storage, providing flexibility in backup storage options.
6. Monitoring and Logging:
   • Proxmox provides monitoring and logging capabilities to help administrators track the performance and health of the cluster.
   • The web interface includes dashboards and graphs for monitoring resource usage, as well as logs for tracking cluster events.
7. Updates and Maintenance:
   • Proxmox clusters can be updated and maintained using the web interface or command-line tools. Updates can be applied to individual nodes or the entire cluster.

1. Using cron:

The cron method is convenient for running commands or scripts at startup. The @reboot directive in the crontab allows you to specify tasks to be run when the system starts.

Open the crontab file

crontab -e

Add the following line:

@reboot /path/to/your/script.sh

Save and exit the editor. This ensures that your script will run each time the system reboots.

2. Using rc.local:

The /etc/rc.local file is traditionally used to run commands at the end of the system boot process.

Open the rc.local file

sudo nano /etc/rc.local

Add your command or script just before the exit 0 line:

/path/to/your/script.sh

Save and exit. Make sure the file is executable:

sudo chmod +x /etc/rc.local

This method may not be available on all distributions, as some are moving away from using rc.local in favor of systemd.

3. Using systemd:

Systemd is a modern init system used by many Linux distributions. You can create a systemd service to execute your script at startup.

Create a new service file, for example, /etc/systemd/system/myscript.service:

[Unit]
Description=My Startup Script

[Service]
ExecStart=/path/to/your/script.sh

[Install]
WantedBy=default.target

Reload systemd and enable/start the service:

sudo systemctl daemon-reload
sudo systemctl enable myscript.service
sudo systemctl start myscript.service

This method provides more control and flexibility and is widely used in modern Linux distributions.

4. Using ~/.bashrc or ~/.bash_profile (for user-specific commands):

If you want a command or script to run when a specific user logs in, you can add it to the ~/.bashrc or ~/.bash_profile file.

Open the .bashrc file

nano ~/.bashrc

Add your command or script at the end of the file:

/path/to/your/script.sh

Save and exit the editor. This method is user-specific and will run the script when the user logs in.

Remember to replace /path/to/your/script.sh with the actual path to your script or command in each case. The appropriate method may vary depending on your distribution and system configuration.
