Regression: KVM no longer supports Intel CPUs without Virtual NMI
Status in linux package in Ubuntu:
Fix Released

Fix Released
Bug description:
== SRU Justification ==
The following mainline commit introduced a regression in v4.12-rc1:
2c82878b0cb3 ("KVM: VMX: require virtual NMI support")
This regression caused the kvm-intel module fail to load with the following
error:
"modprobe: ERROR: could not insert 'kvm_intel': Input/output error"
This error would happen because suppor for CPUs without virtual NMI was
removed
by commit 2c82878b0cb3.
Mainline commit 8a1b43922d0d fixes this regression and was added to
mainline in v4.15-rc1.

kvm: vmx: Reinstate support for CPUs without virtual NMI
== Regression Potential ==
Low. This patch fixes a current regression. It was cc'd to upstream stable
so had additional upstream review.
## Original Bug Description ##
Since upgrading from zesty to artful, I'm not longer able to use KVM on my
server:
# modprobe kvm-intel
modprobe: ERROR: could not insert 'kvm_intel': Input/output error
Searching tells me this is caused by requiring Virtual NMI support[1]
Running the script provided on the mailing list[1] to check virtualization
features confirms my CPU (Xeon E5345) doesn't support Virtual NMIs:
# python features.py | grep NMI
NMI exiting yes
Virtual NMIs no
NMI-window exiting no
Virtual NMI support was required in v4.12[1] and later reverted in
v4.14.3[2] as some models (including Xeons) don't support it, even if
others with the same core do.

This has been fixed for some time, so when can we expect this to be in
an updated Bionic kernel?

Yes proposed works like it should.
There's one thing I'd like to know, though. If the fix was in upstream such
little time after the regression was introduced, why are we still having the
regression in ubuntu after so long?

[Kernel-packages] [Bug 1741655] Re: Regression: KVM no longer supports Intel CPUs without Virtual NMI
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
artful' to 'verification-done-artful'. If the problem still exists,
change the tag 'verification-needed-artful' to 'verification-failed-
artful'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
== SRU Justification ==
The following mainline commit introduced a regression in v4.12-rc1:
2c82878b0cb3 ("KVM: VMX: require virtual NMI support")
This regression caused the kvm-intel module fail to load with the following
error:
"modprobe: ERROR: could not insert 'kvm_intel': Input/output error"
This error would happen because suppor for CPUs without virtual NMI was
removed
by commit 2c82878b0cb3.
Mainline commit 8a1b43922d0d fixes this regression and was added to
mainline in v4.15-rc1.

kvm: vmx: Reinstate support for CPUs without virtual NMI
== Regression Potential ==
Low. This patch fixes a current regression. It was cc'd to upstream stable
so had additional upstream review.
## Original Bug Description ##
Since upgrading from zesty to artful, I'm not longer able to use KVM on my
server:
# modprobe kvm-intel
modprobe: ERROR: could not insert 'kvm_intel': Input/output error
Searching tells me this is caused by requiring Virtual NMI support[1]
Running the script provided on the mailing list[1] to check virtualization
features confirms my CPU (Xeon E5345) doesn't support Virtual NMIs:
# python features.py | grep NMI
NMI exiting yes
Virtual NMIs no
NMI-window exiting no
Virtual NMI support was required in v4.12[1] and later reverted in
v4.14.3[2] as some models (including Xeons) don't support it, even if
others with the same core do.
