Today we have a product which is currently one of the most dynamic lately and it allows you to manage your Proxmox virtual environment (VE) via single dashboard. The product’s name is PegaProx and it is completely Open Source.
If you’ve been following the virtualization space lately, especially since the Broadcom acquisition of VMware shook things up back in late 2023, you’ve probably heard the buzz about alternatives like Proxmox VE. Many home labbers, small businesses, and even larger businesses are actively testing open-source options. Proxmox VE has emerged as a solid contender – a powerful, and based on Debian with KVM/QEMU under the hood.
But managing it, especially if you’re coming from vSphere’s polished interface, can feel a bit clunky at first. That’s where tools like PegaProx come in. In this detailed write-up, I’ll walk you through how to use PegaProx to migrate your VMs from ESXi (or other sources, but we’ll focus on ESXi here) to Proxmox VE. We’ll talk about prerequisites, tips, and some troubleshooting notes based on real-world testing. I’ll also explain why PegaProx is a game-changer for Proxmox users. This is based on the latest beta release (v0.9.0 as of March 2026), so things might evolve, but the core process should hold up.
Note: The tool is in BETA right now so be patient before using it in production.
What is PegaProx?
First off, a quick primer. PegaProx is an open-source, completely free management platform designed specifically for Proxmox VE, but with the latest update also XCP-NG. It’s a unified dashboard and automation layer that sits on top of your Proxmox clusters. Think of it as a modern vCenter alternative for the Proxmox world – it handles multi-cluster management, load balancing, high availability, and now, built-in migration tools.
Developed by the PegaProx project (check out their GitHub for the source code), it’s built with Python (Flask backend) and offers a sleek web UI that’s miles ahead of Proxmox’s default web interface.
Note that there are other alternatives, such as Proxcenter or a tool directly from Proxmox called Proxmox Datacenter Manager.
Key features
Unified Multi-Cluster Control
Manage multiple Proxmox VE clusters from one pane of glass, with aggregate views of CPU, RAM, storage, and network resources.
Intelligent Load Balancing (ProxLB)
Automatic workload distribution using algorithms that consider node health, resource utilization, and even predictive analytics for anomalies. The LB support has been developed with gyptazy and ProxLB
Cross-Cluster Live Migrations
Move VMs between clusters with zero downtime, complete with resource verification and failover support.
User Management and Security
RBAC (role-based access control), LDAP/Active Directory integration, OIDC for SSO, 2FA, and audit logging – enterprise-grade stuff without the enterprise price tag.
Monitoring and Automation
Real-time metrics via SSE (Server-Sent Events), scheduled tasks, alerts, and integration with Proxmox Backup Server (PBS) for backup monitoring.
VM Lifecycle Tools
Create, clone, snapshot, backup, restore, and now migrate VMs seamlessly.
Then, clicking the three dots gives you other options (Delete, force stop, clone, Performance, Migrate or Cross-Cluster Migrate).
It’s compatible with Proxmox VE 8.x and 9.x, and you can run it in a VM, LXC container, or even Docker. No paywalls, no lock-in – just pure open-source goodness. If you’re tired of juggling multiple browser tabs for multiple clusters, then PegaProx modernizes the experience. If you just running single cluster, than you’ll be probably just fine.
Why PegaProx might be a Good Tool for Proxmox Users?
In my opinion and I’ve been blogging about virtualization since 2008 – Proxmox VE is fantastic for its flexibility and cost (zero), but it lacks some polish for larger or multi-site deployments.
PegaProx fills that gap. For starters, it’s the only fully free, open-source tool that brings vSphere-like features to Proxmox without forcing you into proprietary ecosystems. If you’re migrating from VMware, the intelligent placement (similar to DRS) makes deciding where to put VMs a breeze – no more manual calculations of node resources.
Cross-cluster migrations are a great (if you need it): Seamless, live transfers between clusters mean you can scale horizontally without headaches.
Add in PBS integration for monitoring backups, datastores, and jobs from one dashboard, and you’ve got centralized visibility that saves hours. Security-wise, the RBAC and SSO options make it production-ready for teams, while the live metrics and anomaly detection help prevent outages.
For home labbers or small IT shops, it’s overkill in the best way – free features that rival paid tools like vRealize for VMware.
Plus, with the ongoing vSphere exodus (I’ve written about alternatives like XCP-NG and other alternatives before), PegaProx’s new ESXi migration wizard is timely.
It automates what used to be a manual slog: Exporting OVFs, converting disks, injecting drivers, reconfiguring networks. Question really is – is it all working, actually?
Near-zero downtime options mean minimal disruption for production VMs, but is the solution capable to do what it promises it will?
Prerequisites for Migrations
Before starting the migration, it is worth checking a few basics. You will need a working Proxmox VE cluster running version 8.x or 9.x, with at least one node that has enough free storage for the incoming VM. That storage can be local-lvm, ZFS, Ceph, or another supported backend, as long as it has enough capacity for the migrated disks.
On the source side, you need an ESXi host running version 6.x or later, with the virtual machines you plan to move. SSH should be enabled on the ESXi host, since the migration process depends on it. In the ESXi web interface, you can do this under Manage > Services by starting the SSH service.
You will also need network connectivity between the ESXi host and the Proxmox environment. They do not have to be on the same subnet, but the systems must be able to reach each other reliably during data transfer. On top of that, make sure you have root-level credentials for both ESXi and Proxmox, plus a modern web browser to access the PegaProx interface.
For low-downtime migration modes, it is a good idea to check the source VM in advance. Locked disks, active snapshots, or mounted ISOs can interfere with the process and are worth cleaning up before you begin.
It is still best to test everything in a lab before touching production workloads. Proxmox works well for nested virtualization, so building a small test setup with ESXi inside Proxmox is a practical way to validate the workflow before using it on real systems.
Installing PegaProx
PegaProx is easy. The project provides pre-built backup images for quick import into your Proxmox environment, or you can use the automated script/Docker.
The automated script (curl -O https://ift.tt/yma5bwE && sudo ./deploy.sh) handles deps like Python 3.8+.
Example of deployment in my ubuntu VM below.
Follow the instructions and you should end up with the screen like this.
Once up, PegaProx uses AES-256 encrypted SQLite for config – secure out of the box.
Connect to the web UI via https://your_ip:5000
Step-by-Step: Adding an ESXi Server and Migrating a VM
1. Add the ESXi Server: In PegaProx’s left menu, click “Add ESXi Server.” Fill in: Name, Host/IP, Port (default 443), Username (root), Password. Test connection, then add. Your ESXi VMs should populate in the dashboard.
2. Select your VM > Then click the large button “Start Migration Wizard”.
3. Select and Initiate Migration: Click a VM name (e.g., a Ubuntu test VM). At the bottom, hit the green “Migrate to Proxmox” button.
4. Configure Options: In the dialog:
- Target Cluster: Pick from your added Proxmox clusters.
- Target Storage: e.g., local-lvm (avoid Ceph if testing – it can glitch).
- ESXi Root Password: Re-enter for auth.
- Network Bridge: Select vmbr0 or your bridge.
- Check “Start VM after migration” and “Remove source VM” if desired.
- Transfer Mode: Choose “Auto (Pre-Sync + Delta)” for incremental, “QEMU SSH Boot + Live Copy” for near-zero downtime, or “Offline Copy” for full downtime (safest for first tries).
5. Run the Migration: Confirm and watch the progress. PegaProx handles disk copy (via SSH/QEMU), driver injection (VirtIO for Proxmox), network remapping, boot config tweaks, and hardware cleanup.
If fails (my case) then check logs/forums/reddit. In my case I was running only nested environments (for both hypervisors platforms).
6. Post-Migration: VM appears in Proxmox. Boot it, check console for driver issues (e.g., install virtio drivers in guest if Windows). Test apps.
The process automates what manual methods (like ovftool + qm importovf) require: No more dd conversions or manual qemu-img.Tips and Troubleshooting
- Downtime Modes: Near-zero works best for idle VMs; max one at a time. If “VMDK locked” errors hit, manually power off the VM before starting – the wizard’s auto-stop can fail.
- Errors: Check PegaProx logs for “Operation not permitted” – often SSH or lock issues. Enable verbose logging in settings.
- Storage: Local-lvm is reliable; Ceph may need extra perms.
- Windows Guests: Pre-install VirtIO drivers on ESXi side to avoid blue screens.
- Scale: For 500+ VMs, script it via PegaProx’s REST API.
- Caveats: Beta features like live copy are WIP – offline is most stable.
If stuck, hit the PegaProx GitHub issues or Reddit threads (r/Proxmox loves this tool).
Latest Updates
During the time of writing, a new update has been released with tech preview for XCP-NG hypervisor. It would mean that you can manage XCP-NG VMs through PegaProx, which would be kind of cool indeed.
And then when you look at the Add Cluster menu, you have a new XCP-NG (Tech Preview).
So hey, while we are here, let’s add our XCP-NG cluster to the party. Here is the overview of my 3-node XCP-NG cluster. The nodes details, possibilities to enter maintenance node, connect to the shell,
Final Words
If you are looking for a new multi-cluster dashboard for your Proxmox environment, (and soon for XCP-NG environment) PegarProx is definitely a tool to try. As for the migrations, the built-in tool might work, or might not. Don’t worry, there are other V2V conversion utilities in the market if needed. As we could see, during the lab test there was an update from the developers so we could add our XCP-NG cluster.
In 2026, with VMware’s changes still stinging, tools like this make open-source viable for production. PegaProx is a full management suite that elevates Proxmox. Give it a spin.
