How do you get that high consumption? What combination of clocks/hz on
host/guest are you using?
I am cursious, since my idle KVM process is at less than 1%.

What about tsc unstable hosts? If your patch convinces the guest its

Hi everyone,
So far KVM swapping has been a limited feature. Depending on the
workloads huge chunks of the anonymous memory simulating the guest
physical memory could get pinned and unswappable for extended periods
of time. Whenever a spte mapps a host physical page, KVM has to pin
the page to

Hello,
This patch is last version of a basic implementation of the mmu
notifiers.
In short when the linux VM decides to free a page, it will unmap it
from the linux pagetables. However when a page is mapped not just by
the regular linux ptes, but also from the shadow pagetables, it's

FWIW it seems things are broken even without -kernel in -59 too. If I try

Qemu is responsible for handling MMIO emulation, Qemus always assume it
