VirtualBox is ridiculously simple to set up and get virtual machines going. Shared folders, shared clipboard and much more are no issue.
But.
It eats resources. The installed virtual machines (VM) run relatively slow. What have you found to be feature comparable - and most importantly more resource-efficient - alternatives for running VMs under Linux?
I haven’t used it nearly as much as VirtualBox but Boxes (flatpak) is definitely a breeze to use. It uses KVM under the hood I think. If your use cases are complicated it might abstract away too much though.
Surprised no one is saying Xen
This “Beginners Guide” they have there is a serious turnoff. They might want to consider a more lightweight and friendly intro to their software. 😄
Still, if I find the time to go through this massive wall of text, I will.
To be clear, I don’t recommend it. But it was once favored over KVM for a variety of applications and it works in a fundamentally different way. I’m just surprised how quickly it’s lost favor among techies.
