Title:
[A] KVM module in 4.13 no longer supports old Intel CPUs
Status in linux package in Ubuntu:
Triaged
Bug description:
== SRU Justification ==
Impact: systems with CPUs lacking virtual NMI support are no longer
able to load the kvm_intel module, and thus not able to use KVM
functionality
Fix: cherry-pick re-introducing support for software NMI support
Regression Potential: applied upstream in 4.15 and 4.14.3, tested and
verified by multiple people
--
the original dropping of support was (functionally) reverted after
upstream got notified of how many CPUs were actually affected
see
https://lkml.kernel.org/r/<[email protected]>
for upstream patch re-introducing support
see
https://lkml.kernel.org/r/<[email protected]>
for the original upstream patch dropping support and following discusison
I'll send an SRU patch.
