I'm not liking Hyper-V very much.  I was using Hyper-V on 2012 r2 but the OS is EOL  I was able to upgrade all of my machines to 2022 DC and tried running that for a few weeks but every so often the server would crash and take my VMs offline, so I down graded to 2019 DC and while the servers aren't crashing as often they still do.  I have run Vmware in the past but I cant upgrade past 6.7, so I am looking for a Linux hypervisor solution that can run various os's ranging from windows to Linux that has low overhead but will also have a gui (not a desktop, but a page that will allow visuals)  so what is everyone using?  My basic of requirements is to be able to config VMs with a gui, be able to move VMs between hosts either manually or automatically and to have a single place to manage all of the hosts and VMs and to be able to migrate VMs off of Hyper-v to a format that the new Linux hypervisor can use .  Does such a creature exist?  I'm not looking for step by step on how to configure this up, just to point me in the right direction.

I wouldn't say I love it, but from a similarity and ease of use standpoint I do have a number of Linux hosts running VirtualBox

It's not totally great, but free and at least moderately able to be run vis CLI in lieu of the GUI

I'm wanting to get away from windows as the base of the hypervisor and from what I remember about virtual box I can do live migrations from one host to another under virtual box

I've become a huge fan of Proxmox and have a 2-node HA Cluster running at home (last ~2 years) as well as at work now.

ETA: You can import the disks from Hyper-V into Proxmox.

I was going to suggest Proxmox as well.  It is what my data center is recommending now that VMware is going subscription only and killing licensing on the free ESXi.

Look into KVM/QEMU. It runs on most Linux distros but I recommend something Red Hat-based (such as Rocky Linux) for anything server-ish.

As a note here, QEMU/KVM are paravirtualization. They run a container/chroot inside of an existing operating system. This is different compared to ESX, Hyper-V, or Virtualbox.

Not saying it's a bad thing, just a thing to be aware of when considering your migrations.

I utilize ProxMox and it has proven to be reliable and I believe does what you need it to do.

Proxmox is definitely the most capable of all the free options, but there is a bit more of a leaning curve.  If you're OK with that, you can do some crazy stuff.

Salvation lies here.  Take the XCP-ng path and never look back.

Vbox if I'm feeling lazy. Openstack when I need to lab things out.

VirtualBox for a desktop system. Proxmox for a small lab. Openstack if you need big leagues.

I'd say Proxmox or XCP-NG.

I have about 100ish VM's running on XCP at work.  Some of the other Sysadmins use Proxmox, and are happy with it.

8.2.1.  8.3 is still in beta I believe.

It is, I was just looking for some real-world impressions of the differences.

I got curious, and tossed 8.3 on one of my non production servers.  It definitely seems a bit faster, especially when importing templates and VM's.

The XO lite isn't really usable at this point, I'm having to use a beta version of XenCenter to manage it.

I appreciate the info. I'm getting a little sick of the limitations and overhead of Hyper-V and I may just go back to ESXi, even being EOL.  

The other options seem good but each a little half-baked in their own ways.. management UI/UX seems to be the Achilles heel of most.

IMHO, VMware is dead.  Broadcom killed it with massive price hikes.  I'm willing to bet in 5 years you'll only see it in really huge well funded shops.  

If I was starting from scratch, I'd give proxmox a hard look.  Its free, highly functional, and the interface is baked right into the Hypervisor (unlike XCP).  Our web dev guys at work use it and have been quite happy.

For sure. I've worked with Prox, XCP, Nutanix, and some docker-based systems.. If this was for work, I'd probably go with whoever has the best support/feature set intersect, but this is for my home lab and I just prefer ESXi. I don't care about support or lifecycle.

Openstack doesnt need to be a big thing. I've got a beefy single AIO in Vbox to test against customer setups. If doing multi node, keep the AIO for the control plane and just add bare metal for more compute.

I'm biased though. My job has me supporting countless customers private clouds ranging from a handful of servers to thousands. I can openstack in my sleep.

Oh, I didn't mean to insinuate you needed heavy iron to run openstack. Just that if you need a system to run alot of VMs then openstack does it well.
