VMs - Can't Run More Than One

[CuChulainn]

I'm a newb. Please be patient with me.

 

I'm trying to develop my home lab in order to build my resume. Hoping to get a helpdesk job, soon.

 

As I'm trying to follow along with some really helpful guys explaining what the skills necessary to start, one has to do with Server Manager. With or even without that being the case, I'd still like to be able to run more than one VM at once, but I currently can't. It always says when I boot up the second one that the error is HostMemoryLow.

 

I'm working with 4 GB of RAM, nearly 600+ GB disk drive, Intel Core i3 CPU. Yes, it's a laptop, but that's all I have available at the moment.

 

I've messed around with the base memory of both VMs, to no success.

 

Any pointers, tips, tricks?

upgrade your ram.

Ooh 4GB way too low.

 

Storage and i3 should be fine (so long as you're running literally 1 core each.

 

8GB AT LEAST is what's needed, especially if you're using Windows 10 with all the latest updates.

 

I have a client that is trying to do a similar thing on their machine, we're going with 16GB for breathing room

 

100% recommend getting at least 8GB, if not more, gives your PC and the guest virtual machines breathing room

4GB is definitely way to low, upgrading to at least 8GB should allow the VM to run but that laptop in general is still pretty low spec for running multiple VMs depending on what you are trying to use them for. If it's a 4 core i3 you can run two VMs with 1 core each but if it's a dual core i3 which most i3 laptops are you'll run into major performance issues trying to run more than one. I'd recommend piecing together a  6 to 8 core CPU desktop with at least 16GB of Ram and a 1TB SSD for a VM/ server setup especially if you plan on using it for work.

What OS are you trying to run in your VMs? Host OS? You can run multiple VMs on a system with only 4GB of RAM, but it's tight, and you'll have to be extremely conservative in your RAM allocation to each VM.
