KVM Desktop Setup Ideas

@IRJ said in KVM Desktop Setup Ideas:
Virtual box is terrible. I really don't know anyone who I would take seriously that uses it. If you want something that has great GUI and more than the basics available via GUI. Use VMware workstation. Yeah you have to buy it, but virtual box is so lame, slow, and has issues.
Virt manager has the same options as virtual box, so when is there ever a reason to use virtual box?
No one has implied that the quality of any Type 2 hypervisor is worthwhile. We're still attempting (I think) to discuss how this hardware is intended to be used.

KVM is also nice because you can continue using that machine as a regular desktop as well, if you need to do so. (Can't do that with VMware, Hyper-V or XenServer).
No one expects to use their Type 1 hypervisor as a desktop.
I use Hyper-V on my laptop all the time. Nothing that is actually a productive server, but lots of demos.

What combo is best to "get started" with KVM?
It's just for a standalone machine to host 5-6 VM's.
If they are all linux based, you could run 15 on that.

When you set out with the need to run VMs was the original intent to do so on your laptop, or later on was the question raised "can my laptop be used to act like a Type 1 hypervisor?"
The order of the questions matter, as they lead you to the result.

If they are servers, not desktops. Most desktops will crap out at that low.

Wow this has become a long thread. Missed a load of stuff. Had a quick look over and need to clarify a few things.
I have a Desktop machine (Dell optiplex 9050, i7, 16gb Ram, 240ssd and 500sata)
This is going to be used as a lab only. Managed remotely like a server would. I've used ESXi before, XenServer, Hyper-V.Even Windows 10 Pro with Virtual Box, VMware player and workstation. Windows 10 with Hyper-V enabled.
The only Hypervisor I haven't tried yet is KVM.
Hence the question where to Start.It'll run a VM as a firewall
One Linux VM
Three Win10pro
(Because the Win10 VM's hence the need to upgrade the RAM) -
When I say combo I mean what Distro as a base os (fedora seems to be popular) and what to use to manage it remotely.

Fedora Server works great.

I really like just using Cockpit. So I start with the latest Fedora which is 29. Install KVM. That's about it.
There are some things you will want that it lacks, but they are mostly around creating the VMs, not day to day. So while they suck and need to be done at the CLI, I still prefer it most of the time. At least for stand alones.

I have VMs on my local desktop with Hyper-V. Not production but they are good for a lab.
Is it your expectation to use XenServer as a desktop?
FFS did I say something that was confusing.
This is not an expectation generally made that a Type 1 Hypervisor can also be used as a daily driver. Persons who do this are making a case in which they need a daily driver and a Type 1 Hypervisor.
It is not the normal expectation.
I'm late to this - but I absolutely want this - hell I want this for normal users so they can be more protected.

I think you could with VDI. Just gets expensive.

.....
The only Hypervisor I haven't tried yet is KVM.So wait, it's desktop hardware, but being treated as a server? That's totally different.
KVM, yes, obviously since that is part of your goal. But definitely not with a local screen. This goes back to ... "I like Cockpit."
If you are just trying to learn, take a look at oVirt, too.

These three posts seemed to lead to all the problems
@hobbit666 mentions that he's using desktop hardware
which leads @dafyre to assume "regular desktop"
Which leads Scott to assume daily driver (though not said in this post)Now we find out 10 mins ago that this machine while being consumer hardware will in fact be used as a typical, likely headless server.

Yeah - normals would love VDI if there was a super easy/cheap way to do it.
It's not THAT bad these days.
Normal users would have a hard time paying $100/yr for it - hell I can't get normals to pay $50/yr for offsite/online backups.
Is it that much now? I don't think so.
You can get Windows VDI for less than $100/yr? I thought the VDI license was that much alone, let alone someone's platform upon which to run it.
Also is VDI in someone else's DC now legal? I thought it wasn't for a while there because you didn't know what hardware it was on? - though I might be misremembering that.

To be fair, you are correct, I did assume "regular desktop". However, that still doesn't change my recommendation of KVM + Virt-Viewer (I use Virt-Viewer to manage a couple of KVM servers).

AMD Ryzen and disable SMT, get something with NVMe M2 storage, buy cheapest m2 storage, install OS there, make RAID on the SATA disks, or something else, and use those as VM storage

Why? Your OS gets loaded to memory having it on an SSD when your actual workloads aren't doesn't make a lot of sense.

Exactly - this is the same reasoning that you don't install ESX-I or Hyper-V on it's own drives - it's a waste of IOPs. Instead give those IOPs to the workload - i.e. just make OBR10, not a smaller RAID 1 for hypervisor and OBR10

So to continue this conversation.
If you have the space and available hardware, install Fedora Server 29, the KVM role (headless virtualization) and use Cockpit to manage the machine from a remote system.
You could, and is the recommended approach would use Virt-Manager (from a Fedora Workstation) to connect to this KVM hypervisor remotely and manage your VMs and Hypervisor with that. Rather than just using Cockpit.
While Cockpit is a great tool it isn't at all like what many of the other tools you may be familiar with are like.
Virt-Manager would be like XenCenter, where Cockpit would be like XO.

Going down the rabbit hole of how and where to install Fedora (to SSD, winchester, SD card, an array) all comes back to best practice and what you have at your disposal.
If you have a hardware raid card that would be a good solution to use, as most commodity servers will come with this type of functionality and setup function.
I create my array and then I install my OS (or hypervisor)
If you don't have hardware raid and are wanting to not spend any additional money on this unit, just install Fedora Server with the KVM role directly with how the system assigns the storage. No changes need to be changed. Especially since it appears you're just wanting to learn how to use and manage KVM
