Minimal VM

Asked by john novak on 2021-04-21


I wonder what was the most minimalist VM that you were able to run SikuliX, incl. java and desktop screen?
In my case i got it working on win7 (not sp1) on KVM/centos7, >10y old thinkpad.
Failed with Lubuntu, didn't work well, Sikuli window was all yellow, not starting, looked like malfunctioning.

Now I'm looking for something that would be same size or more lightweight (cpu&ram) than mentioned win7.

I would like to get all your opinions on this.

Have a nice day,

You did not mentioned any CPU & RAM...

HW, host:
- cpu has two cores, it is Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz
- ram: 4 GB
- Vt-x available, no vt-d/iommu
- os: centos7, KVM installed

- 2GB of ram
- one vcpu
- os: win7, not sp1, added virtio drivers for storage, network
- java: jdk-16
- sikulixide-2.0.5.jar

When running SikuliX in above VM, htop in centos says:
- around 35% cpu usage (two cores, 2x100%, max would be 200%) while idle and waiting for commands
- 80-100% when running 10 step "click(Lcation(...))" macro

My goal is to minimize VM requirements, still having sikuli working. Then I could duplicate VMs to run them in parallel.

Can you help with this problem?
