Interesting ideas Jakob. Where can I post this as a feature request so
it gets more attention?
N.B. My second solution suggestion is not the way to go. High precision
timers in virtualizers have bad security implications but there is no
way around them. They enable side-channel attacks on crypto operations
running on other VMs as well as aid in biometric fingerprinting. A multi
hypervisor study on timer accuracy shows most have high accuracy by
necessity. Increasing coarseness in the hypervisor's code can lead to
guest slow downs or instability.[1] The amount of coarseness they can
take varies by hypervisor. CPU load does NOT affect timer accuracy [in
KVM] however IO does.
