I've used proxmox . It got me up and running with a gui quick. But I've also use virtual box ( oracle : yuck ) and that also got me up and running quick. "professionally" I sit in front of a lot of vmware, but that's closed / for pay / proprietary / expensive. ( but feature rich ) (I've not used libvrt / rhev / kvm so my perspective is limited) David On Fri, Aug 26, 2016 at 11:34 AM, Lennart Sorensen via talk <talk@gtalug.org

If I wanted to set up a host for a bunch of headless VMs, what's the OS/Hypervisor to run these days? I'm doing this out of curiosity and for testing purposes. I don't exactly have appropriate hardware - an i5 with 16GB of memory - but it should be sufficient to run 5-10 VMs for my very limited purposes (private network, none of the VMs will be public-facing). QEMU/KVM looks like the best choice for a FOSS advocate? Other recommendations? I could particularly use a good HOWTO or tutorial if anyone knows of one. Thanks.
I certainly like kvm. Works well. Finding examples for how to start if isn't hard. I am personally NOT a fan of libvirt and the associated crap it provides and much prefers just making a shell script to pass the right arguments to qemu myself.
As long as you have VT support (Most if not all i5s do, as long as it is on in the BIOS/UEFI), I would think that should be fine. 16GB would certainly allow you 10 1GB or 5 2GB VMs without any issue. Creative people would try and use KMS (kernel memory sharing I think it is), to merge identical pages between VMs to save some resources. It's a neat feature.
Depending on what you intend to do with them and put in them, some people might use containers instead (like lxc and such). It has its own limitations but uses less resources. If you are looking to run different OSs though, then containers are not what you want.
