would Vms run better on a light gui host?

Recommended Posts

Posted · Original PosterOP

I was gonna install ubuntu as my main os, but since id need Remix, mac, and occasionally windows for when ubuntu has a game that will juat not run. I'd have 3 vms. Make that 4 if i have a ubuntu as my main in a vm, so would it be better to install something light as possible like puppy if it has a version of virtual box and have 4 vms  or keep ubuntu as a main and go 3? id run only one at a time, have 16gb ram, and 6 cores of 4.0 or close to it with no oc. Sorry if this is in wrong place. was here or os page.

Since you'll be interacting with the VM instead of the host-OS GUI, it doesn't really make any difference -- Ubuntu, by default, uses GNOME3 and it isn't constantly doing something in the background, drawing on the desktop or such. The only thing a less lightweight solution does is use RAM, but you have 16GB of it, so that shouldn't be an issue.

thing is, i'd be interacting with the host if ubuntu wasn't in a vm. But if using puppy i'd not use puppy at all, just it'd be a host for whatever vm i'd use with only the game open. if using ubuntu as a host id have music, discord which uses an oddly high ammount of resources, and usually some other app in ubuntu and the game in the vm. @WereCatf

okay nevermind. reread that, going ubuntu see your point. 1ram gb won't make a diffrence. whats a safe thread/ram amount to give the vm while running.

 

i know on my laptop (1.1ghz quadcore 8gb ram) that has ubuntu i can give 3 cores 6000mb ram and be fine unless its windows 10 in a vm. that will freeze my pc during vm boot for a bit then be fine. yet this was faster than native win10 when i had duelboot. kinda funny.

Going with a reputable distribution of GNU/Linux you're already off to a better start than using Windows as the hypervisor.

I admit I have not tried Oracle VM VirtualBox on Linux but if you want high performance virtualization look into QEMU. I have a tutorial or two on how to set it up. It can be configured to give your VMs very near native performance even under high computational loads.

If you don't need GPU pass-though or Audio you can skip all of those steps and just setup QEMU and follow the Performance Optimization section.

VirtualBox does have a PCI Passthrough extension so theoretically it *should* work doing VFIO passthrough but in practice I think its a very tricky thing to get going. 

You of course need to have a system that supports IOMMU (VT-d/AMD-Vi) and directed pages (VT-x/AMD-V), you need to enable IOMMU, you then need your kernel to support IOMMU (I believe the latest Ubuntu's do this OOTB), You then need to install VirtualBox and the extension package for VFIO PCI Passthrough. Then you should be able to attach the GPU by its IOMMU group number to the VM. It would have to be a secondary card also since your card would be in use by Ubuntu.
