Is it possible to run Proxmox up on an online hoster like Vultr or similar so I can have a look at it. Any suggestions??
You'd need to use a bare metal server. Vultr offers these, but only at $120/month currently.
Yeah, I started looking at these last night, too expensive. I remembered I have an i7 laptop. Otherwise I might have bought a 2nd hand something online.

There are a few issues that haven't been really vetted.
You mention that these servers run a custom software that allows access to the the data. This is fine, so long as you can virtualize the existing physical servers and run them as virtual machines.
- The big if being that there isn't some custom hardware that doesn't support virtualization
The next question to be raised is if they were hit with a virus, how would virtualizing these systems fix this issue? Virtualizing offers many features, including the easing recovery from such events, but that doesn't make the system more secure from viruses.
- Are these systems going to be air-gapped from the rest of the world?
Last you've asked what hypervisor should be used, there are a plethora of them.
- ProxMox is a full management stack and hypervisor in one.
- XCP-Ng is another, that you'd then optionally install XenOrchestra (likely by "building it yourself" or using my github script).
- You could of course install Hyper-V and use Hyper-V manager as well (another totally free Hypervisor and management solution, albeit backups aren't included)
I believe ProxMox is locally managed only (meaning you'd need to be on the LAN). If you're performing any maintenance for the client in the end, this may be an issue.
XCP-Ng can be managed from XenOrchestra which can* hosted in a cloud environment easily and securely.
Hyper-V has no such option as far as I'm aware.
You also mentioned TB's of storage, virtualizing a physical server does nothing to reduce the amount of storage the system is using or has allocated. You're just changing where and how the storage is presented.
I'm assuming these servers likely have hardware or software RAID, converting these VMs for this may be a bit more tricky due to this.
Thanks for all the info Dustin, much appreciated.

You don't have any extra desktops or laptops not being used so can install Proxmox on it?
Last night I remembered I have an i7 16GB laptop lying around, so I'll fire that up. Thanks for the help.
Now if you planning using the laptop, you will want to disable the laptop from going in to standby mode when or if you close the lid.

https://thedaneshproject.com/posts/disable-laptop-lid-action-for-proxmox/Thanks black3dynamite, i'll bookmark that.
Also found out that Proxmox doesn't have an easy way to get onto wifi, so i'm sorting that out atm. -
Gave up on wifi, found it's not worth the effort, can be a bit finnicky.
Anyway, got Proxmox installed with a test Windows server, a relatively painless process.
Next on the look into list, is see if I can create VMs from vhdx files in Proxmox?

just had a quick look at xcp-ng, it looks very good as well.
I'm wondering which one I should concentrate on, Proxmox or xcp-ng?
I don't know either. Possibly the biggest thing I'd like to be able to do is be able to migrate VMs off Hyper-V and onto one of these 2.
Does one have a better support community than other?
Does one have a more mature product than the other?
Does one have better tools than the other?
Is it easier to migrate from Hyper-V to one, more than the other?Thanks for any help.

@siringo said in Windows Servers Archived onto Linux, suggestions/help pls:

My straight up answer is to try them both out.
-
There are tools to help with migrating VMs. I know we have guides here for KVM (Proxmox). I believe we have some here for XCP-ng or XenServer.
Personally, I would create a new VM on Proxmox or XCP-ng and then sync the data over.
They both have pretty good community forum.

@siringo said in Windows Servers Archived onto Linux, suggestions/help pls:
I have a client that wants to repurpose 3 Windows Servers that are no longer used but contain data that needs to be kept.
The data can be read by specialised software that is installed on the servers.
I'm thinking of running up a Linux box and having these servers run as VMs on the Linux box so the data can still be accessed.
Remember licensing. MS Server is licensed after physical cores on the hypervisor, not the VMs. So moving from a physical server to a virtual might require higher licensing costs.
Same goes for the software that's on these servers. You have to know what it is and how it's licensed.

@siringo said in Windows Servers Archived onto Linux, suggestions/help pls:
I'm not a Linuxer
I think you are better of with vmware essentials. It's low cost and don't have all the bells and whistles but there is a lot of people in the "windows world" that can manage it and you don't need any linux knowledge at all.
We use xcp-ng & xenserver and while it has a windows client for managing that is really good, you still need to be able to do things in linux to get by. Same thing with proxmox.
So for a windows shop with people that has windows knowledge, vmware makes more sense. Even if there are options that gives you more value for money.
But I suggest starting to play with some linux virtualization in your home lab.
-
thanks for the help @Pete-S I appreciate it.
I'm not worried about any MS licensing, the old servers will just be used for reference should any need ever arise for the data on the servers to be looked at in the future, they won't be in production and will likely stay shut down.
That's why I was looking at an open source virtualisation platform, I was wanting to come up with a solution that wouldn't cost much, if anything, and have no licensing issues.
Again, thanks for the help.

@black3dynamite thanks for your help black3dynamite, I really appreciate it.
What's the relationship between xcp-ng and Xen Orchestra? Doesn't XCP-NG have adequate management functionality on its own, or does it, but it's hard to use?
Just wondering what advantage Xen Orchestra offers???

Xen Orchestra was their original product. It's a web based management platform for XenServer.
XCP-NG, being the open source compilation of XenServer, has the same management tools as XenServer. A windows based installed program and a local tui.
So Xen Orchestra to either system is a big plus in that you are no longer tied to a single OS for managing the system remotely. In addition to all the other features it brings, like patch management and backups. @DustinB3403 install instructions and script still work great https://mangolassi.it/topic/12809/xen-orchestra-community-edition-installing-with-yarn

@travisdh1
++ XO also exposes and simplifies a lot of functionality that would otherwise require mucking around in the xen CLIUnfortunately XO also lack some of the features that the native windows clients has. Like custom fields for the VMs. Something we use all the time.
XO is also much slower than the native client for certain use cases. And it lacks the powerful tree structures that the native window client has. They're working on a new UI I think. XO is also resource intensive, much more so than many other web interfaces, but that's a minor thing.
For us the management tools matter. If xcp-ng drops the powerful windows client, we will migrate to something else, probably KVM. KVM has more mature tools for automation as well but we use our own scripts for xen so we get by.

Just installed Proxmox on a Dell T620 with 4 x 600GB physical disks.
Proxmox tells me this:
When I installed I didn't install any RAID option, I just chose the default.
I know this is elementary for you linux guys, but is that telling me that it has used 3 of the disks to create a volume of size 557.87GB?
If not and it's only using 1 physical disk, how can I add more disks for Proxmox to use?
Thanks for any help.

You must be looking at LVM under Disks because that’s normal. Take a look at LVM-Thin under Disks.
