My 100 series skylake / i5 6600k doesn't support apicv and used to have
x2apic off by default. A recent bios update however switched x2apic on
whilst also (finally) providing the cpu firmware bug fix. Consistent
with the claims in this thread however I found I have to add nox2apic on
my kernel

LGA 2011-3 Processors like your Ci7 5930K are Haswell-E, NOT standard Haswell,
they are not the same. There may be Core
With Ivy Bridge-E, Intel introduced their APIC Virtualization extension, APICv
(Rather contradictory, on other sources its called vAPIC). APICv seems to be
built on top of x2APIC, so it requires it to be working on the host to be used.
You can check that in the host by using:
dmesg | grep x2apic
