Proxmox Live Migration Without Shared Storage
Proxmox is a popular open-source virtualization platform which allows users to easily manage virtual machines and containers. One of the key features of Proxmox is its ability to perform live migrations, allowing you to move running virtual machines from one host to another without any downtime. In this article, we will explore how to configure Proxmox live migration without the need for shared storage.
Live migration without shared storage is a useful feature for small to medium-sized environments that do not have a dedicated shared storage system. By using Proxmox’s built-in features and a few additional configurations, you can easily set up live migration between hosts without the need for expensive storage solutions.
Prerequisites
- Two Proxmox hosts running the same version
- Network connectivity between the hosts
Configuring Proxmox Live Migration
Follow these steps to set up live migration without shared storage on your Proxmox hosts:
Step 1: Enable Live Migration
Log in to the Proxmox web interface and navigate to the Datacenter section. Select the Datacenter node and click on the “Edit” button. Check the box next to “Enable support for migration.” This will enable live migration on your Proxmox hosts.
Step 2: Configure Encryption (Optional)
If you want to secure your live migration traffic, you can enable encryption by adding the following line to the /etc/pve/pve.conf file on each host:
migrate encryption
Step 3: Configure Network Interfaces
Make sure that each Proxmox host has at least two network interfaces – one for management and one for migration. You can configure the migration network by editing the /etc/network/interfaces file on each host:
auto vmbr1iface vmbr1 inet staticaddress 192.168.10.1netmask 255.255.255.0bridge_ports eth1
Step 4: Test Live Migration
Once you have completed the above steps, you can test live migration by moving a running virtual machine from one host to another. Simply right-click on the virtual machine, select “Migrate,” and choose the destination host. The virtual machine will be migrated without any downtime.
Conclusion
Setting up Proxmox live migration without shared storage is a simple and cost-effective way to improve the flexibility and reliability of your virtualization environment. By following the steps outlined in this article, you can easily configure live migration between Proxmox hosts without the need for expensive shared storage solutions.
