[Bug 503138] Re: after kernel message hrtimer: interrupt too slow.... the kvm guest becomes slow [possible solution found!]

[Mark Deneen]

See: https://patchwork.kernel.org/patch/89734/

According to Michael Tokarev, the guest is swapped out and needs to
handle a timer interrupt.  It gets swapped in by the host, but this
takes some time.  The next timer fires BEFORE the previous timer, so the
guest thinks that the interrupt is too slow and things go downhill from
there.

This does not resolve the problem, but it allows the guest to handle it
gracefully.
