With Broadcom’s acquisition of VMware leading to price increases, many are considering Proxmox as an alternative. A key feature to replicate from VMware is live migration, which allows moving VMs between hosts without downtime. Proxmox achieves this using NFS storage, offering a simpler setup compared to VMware’s VMFS or hyper-converged solutions like Ceph.
Why NFS for Proxmox?
- Live Migration Support: Enables seamless VM transfers between Proxmox nodes.
- Hardware Reuse: Works with existing SAN storage that supports NFS.
- Simpler Than Ceph: No need for deep expertise in distributed storage systems.
You Should Know:
Setting Up NFS for Proxmox
1. Install NFS Server (Debian/Ubuntu Example):
sudo apt update && sudo apt install nfs-kernel-server -y
2. Configure NFS Exports:
Edit `/etc/exports` to share a directory:
/mnt/proxmox_storage (rw,sync,no_subtree_check,no_root_squash)
3. Restart NFS Server:
sudo systemctl restart nfs-kernel-server
4. Mount NFS in Proxmox:
On each Proxmox node, add the NFS storage via CLI or GUI:
pvesm add nfs <storage_name> --server <NFS_Server_IP> --export /mnt/proxmox_storage --options vers=4
Live Migration Command
To migrate a VM from one node to another:
qm migrate <VM_ID> <Target_Node> --online --with-local-disks
Verify NFS Mounts
Check active NFS mounts on a Proxmox node:
showmount -e <NFS_Server_IP>

What Undercode Say
Proxmox with NFS provides a cost-effective, high-availability solution for those migrating from VMware. While Ceph offers scalability, NFS simplifies storage management without sacrificing critical features like live migration. For Windows-centric environments, Hyper-V remains complex, making Proxmox a compelling alternative.
Expected Output:
Live migration complete. VM <VM_ID> successfully moved to <Target_Node>.
