I’ve been reading / following your problems and solution attempts.
I myself have been using VMWare since 1999 til about 2015, when I moved to Proxmox…
I’ve just finished updating all my 25-30 clients, all using NethServer as AD and more. All my clients run NethServer virtualized in Proxmox, for a few very good reasons…
I never had any such or similiar issues with Proxmox as Hypervisor.
Please have a serious look at running Linux on Linux, instead of running Linux on Windows - with headaches!
Advantages of Proxmox:
- Completly free, you can license the support and “tested” update repos, but the cost is - compared to the competitors (MS Hyper-V, VMWare ESX, or Citrix XEN) very simple and cheap: It’s licensed per CPU socket (only). Cores are ignored where licensing is concerned! Only 4 price options for support, and I only use community support, it’s enough! You CAN run Proxmox without any support or license costs!
- Live Backups of any running OS, including Windows (With Exchange or eg SQL-Server).
- Live, fast Migration cluster, up to full High Availibility Cluster (Full-HA).
- Only Hypervisor which can handle Full Virtualization (like the other three) but also Linux Containers LXC.
- Can use ZFS or CEPH out of the Box.
- Very solid and stable, needs maybe one reboot a year! Plenty of updates, but no reboot needed unless a new Kernel is introduced…
- Easy migration / converting for VMs already running in another virtualization, eg Hyper-V -> Proxmox or VirtualBox -> Proxmox.
With Proxmox, it’s possible to backup a running VM (Live Backup) and restore that Backup on another hardware (completly different, eg AMD instead of Intel) - and no Microsoft licensing or reactivation issues! Proxmox virtualizes even the CPU (KVM Standard CPU), so a Windows system doesn’t detect any changes underneath. This is NOT possible with the others (Hyper-V, VMWare ESXi, XEN)!
I’ve restored a complete Hotel-IT (MS Server 2008R2 with SQL-Server) from a HP Proliant to a Mac-Mini, really different hardware, and no licensing issues or activation issues! This just as “proof of concept” to my client (and my business partner!).
There are good and valid reasons why Hyper-V isn’t used by many members on this Forum. We also have a few Xen fans here, and quite a few VMWare ESXi users.
But by far the most are happy Proxmox users! (Devs, Power Users, etc!).
A small test environment could be an older PC with at least 8 GB RAM - Proxmox is installed in 20 minutes…
