It will likely be e= ither HPET or ACPI which means there is an VM exit whenever the guest reads from the emulated timecounter hardware. That's why I have some WIP to add support for KVMCLOCK [1]. I hope to merge those changes to HEAD in a week and STABLE shortly after. In the meanwhile, not completely foolproof workaround is to use the TSC-low timecounter source.
