I have been facing problem with my host machine having 4GB RAM and Intel Core i3 (2GHz) processor. I am trying to make a cluster with few virtual machines (VMs). Anyway, It is just fine with 2 VMs having 1GB RAM. The system is just out of control when the number of VMs is more than 2 and hence it is required to force reboot so that it is operable again.
- Is the any general rules for running the maximum number of VMs at the same time (depending on the RAM, CPU etc)?
- Can a virtual memory or a swap memory (at the host machine) is helpful to overcome this problem?
I re-create same VMs on my lab where the RAM were 32GB (8GB usable) with intel core i5. This is not also very much helpful and I am facing same problem.
Again, I tried to make these VMs on some other computer with 63GB (8GB usable) RAM. This time it is also happening somethings.
From these setup, I got my 2nd question that I asked here.
