Recently, I tried virtualising a jenkins instance in my company, meaning jenkins should go into some KVM domain. Well, jenkins itself ran just fine under these conditions, but virtual box did not perform very well. We made sure all nested virtualisation options were set correctly. The jenkins guest is able to use processor-flags vmx, ept and vpid. /sys/module/kvm_intel/parameters/nested states nested paging is enabled with an 'Y'.
I asked at the virtual box forums for experiences running virtual box inside a KVM domain, but they could not really give me a hint. Anyway, I meanwhile accept answers like "nested virtualisation does not perform very well". We just gave it a try. Unless anybody here tells me he has managed to run VB inside KVM with good performance results, that is fine, we accept that. The only thing I am still wondering about is, how do people run a setup of vagrant + virtual box + jenkins in the cloud? Cloud servers are always virtualised, so we have nested virtualisation there, too. Can anybody confirm vagrant + virtual box + jenkins is running fine in the cloud? Let's say with an Amazon EC2 instance? The guys from the virtual box forum sent me here, as they actually do not use virtual box in CI environments. So they cannot say. Any experiences?
