Dear Virtualbox Developers, Are there plans to support performance counter virtualization (aka PMU virtualization) in VirtualBox ?
This already supported by VMWare for some time now. See https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2030221 for instance. This has been discussed in the past with some tentative discussions ( https://forums.virtualbox.org/viewtopic.php?f=1&t=59168 ) but no definitive view on whether Virtualbox is interested in this / already working on this / has decided not to support this... Allowing PMU virtualization allows some really powerful software (e.g. http://rr-project.org . Also see https://github.com/mozilla/rr) to be run in the VM. Thanks, Sidharth
