5 Things to Know About Running Three 2GB Linux VMs on 16GB RAM

16GB is enough for three 2GB Linux VMs Your host needs about 2GB, leaving 14GB for VMware. Three VMs at 2GB each is 6GB, plus roughly 1-2GB of VMware overhead, totaling 7-8GB. You still have 6-7GB headroom for host apps or bursts.

With 8GB, you were running two VMs at 4GB allocation plus the host That setup was tight. Any extra load would hit swap. Moving to 16GB gives you plenty of breathing room.

VMware adds about half a gig of overhead per VM So three VMs actually use around 7-8GB total, not just the 6GB you allocate.

You still have 6-7GB of headroom for host applications or burst usage No swapping needed. That extra space handles spikes without performance hits.

This assumes your Linux VMs are not memory-hungry If those VMs run heavy workloads, you may need more RAM. For typical use, 16GB works fine.
