Run it over the cloud.

Laptop hardware is not able to support a few VMs in my opinion.

Re

You'll need one with at least an 8 or 10 cores laptop

If you are using 1 VM then you can assign 4 or 5 cores to it

If running 2 VMs then assign 3 cores to each

If running 3 VMS then assign 2 cores to each

Intel 10th Gen CPU COMET Lake Core i7-10875H has 8 cores

Can read up something here on resources alloaction when running multiple VMs

Laptops are not meant to be virtual hosts.

Either host the VM on the public cloud or splurge thousands on an expensive mobile workstation.

Also, anyone who says that VM is dependent on processor cores is BS-ing. The bottleneck for virtualization has never been CPU resource. In fact, CPU resource can always be safely overprovisioned by ridiculous factors without any significant impact on performance. Public VM platforms often oversubscribe CPU resource to VM loads by more than 10x and can still guarantee the performance level that the subscriber paid for.

I have once hosted 15 VMs running concurrently on a quad core processor without running into performance issues. It all comes down to knowing where the real bottlenecks are.

You were using your 15 VMs simultaneously or 1 or 2 at the same time? Able to start 15 or 30 VMs is different from running simultaneously.

I said 'concurrently'.

Concurrent means at the same time.

It can means opening all the VMs at the same time or running all the VMs at the same time.

Which is which? Please be more specific

"I have once hosted 15 VMs running concurrently"

I don't see how difficult it is to understand.

So you are running concurrently, right? You'll need 5x external 34-inch monitors to see your programs running concurrently assuming each 34-inch external monitor is set to run 3 programs.

If you say you only need your laptop screen to SEE all programs running concurrently I say you BS. Or if you say you split a single 34-inch monitor into 15 screens to see the 15 programs running concurrently I say you BS

Because such tiny screens don't serve a purpose. Do you really have 5x 34-inch external monitors at home? Or you have an 80-in screen TV to display your 15 VMs running onto it?

One other thing on running concurrently. If simply opening a program and leave on the screen is NOT running concurrently. If you are watching video, enjoying Youtube, surfing the net, working on your Word/Excel, doing program compilation etc that is concurrent running, ok? Remember you said you have 15 VMs running concurrently.

Can you answer my question more specifically? Opening concurrently or running concurrently?
I have already been very specific from the beginning. The bolded portion says everything that I need to say.

Who says that VMs need a window or GUI?
