It's exactly the other way round. Virtualbox is a painless out of the box solution satisfying a lot of needs. Only if you have a very special need, consider to migrate to something less comfortable such as KVM.
What part of using libvirt with virt-manager isn't "out of the box"?
Hi, maybe the OP has got a reason to chose Virtualbox in the first place, but the OP might be willing to migrate to virt-manager with KVM, where everything is or is not hassle-free. There's no need for an off-topic discussion, I'm not affected anyway.
And if virtualbox performs adequate you gain absolutely nothing from those performance gains, but you'll lose all the out of the box features virtualbox provides, such as file sharing without any effort.
Virtualbox performance is not even comparable with qemu-kvm. They are on different leagues.
I never question it, it's just that if somebody should run Virtualbox to e.g. get a single Windows program running, that doesn't work with wine and there should be no performance issues when running that program in a Virtualbox guest, better performance doesn't matter, since it's not needed at all. I'm well aware that a lot of other use cases are possible, that make KVM a better choice, but I don't remember that the OP asked for a VM with better performance. As long as 4.19 is longterm supported and I shouldn't change my hardware and/or Linux computer usage, I stay with 4.19 rt patched kernels I build myself. For users with different needs and/or different hardware this doesn't make sense. Btw. those using kernels from the repositories would be wise to use "IgnorePkg list, and upgrade them only in a strictly controlled way", e.g. as long as linux 5.11 is in testing and linux and linux-lts are both 5.10 ;). I suspect Jens John won't encourage users to hold back kernel updates, he probably just wanted to point out that even a rolling release might be used for a production environment and holding back a kernel update when being busy, is different to partial upgrades of other packages.
