VirtualBox 4.2 Virtualization Benchmarks
Phoronix: VirtualBox 4.2 Virtualization Benchmarks
For those curious whether the forthcoming Oracle VirtualBox 4.2 virtualization platform delivers on any performance enhancements, at least as it pertains to Linux virtualization, here are some quick benchmarks.
Very cool, thanks!
Is there a chance we'll get to see qemu/kvm vs. vmware vs. virtualbox throwdown?
Seconded, in particular Graphic performance is interesting to me...

The interesting thing is that graphics benchmarks make it look like it actually has decent performance, but somehow the screen isn't updated at the same frame rate so, even if glxgears says it's outputting 500fps it still looks like 5-10fps. I don't get it.
I haven't ever seen Devius' problem that I can recall.. but I do wish VirtualBox would step up their performance somehow. These numbers compared against bare metal were just depressing.. and can we get GPU passthrough support? I don't care if the host has to switch to purely software rendering to do it..
GPU passthrough means giving complete access to the GPU to the VM, so the host must use another GPU (if available) or become headless, not even software rendering. So unless you do have a second GPU I don't think this is what you really want.
Phoronix test suite keeps crashing on me in VirtualBox 4.1.20. VBoxDD.dll is blamed as the fault module when it goes down.
