[Impact]
Our Bionic 4.15 kernel lacks of movups/movupd emulation support.
With the following commit added into the emulator test in ubuntu_kvm_unit_tests:
8726f9771911d6749dbd36ab2fc70f0f25e2b1a9 is the first bad commit
commit 8726f9771911d6749dbd36ab2fc70f0f25e2b1a9
Author: Jacob Xu <jacobhxu@google.com>
Date: Wed Apr 21 16:12:57 2021 -0700
x86: add movups/movupd sse testcases to emulator.c
Here we add movups/movupd tests corresponding to functionality
introduced in commit 29916968c486 ("kvm: Add emulation for movups/movupd").

[Fix]
* 29916968c48691 kvm: Add emulation for movups/movupd
This patch can be cherry-picked into Bionic.
It can fix our test failure plus, mentioned in the commit message, emulation failures with openbsd as guest and with Windows 10 with intel HD graphics pass through.
I didn't see any other patch claim to be a fix of this patch in upstream tree.

It's just adding new capabilities, the problem I think of for the moment is that we might see other failures when using this in the future.

[Fix]
* 29916968c48691 kvm: Add emulation for movups/movupd
This patch can be cherry-picked into Bionic.
It can fix our test failure plus, mentioned in the commit message, emulation failures with openbsd as guest and with Windows 10 with intel HD graphics pass through.
I didn't see any other patch claim to be a fix of this patch in upstream tree.
[Test]
Test kernel can be found here:

[Fix]
* 29916968c48691 kvm: Add emulation for movups/movupd
This patch can be cherry-picked into Bionic.
It can fix our test failure plus, as mentioned in the commit message,
emulation failures with openbsd as guest and with Windows 10 with
intel HD graphics pass through.
[Test]
Test kernel can be found here:
https://people.canonical.com/~phlin/kernel/lp-1932966-kvm-emulator/
Run the emulator test from ubuntu_kvm_unit_tests, with this patch
applied it will pass without any issue:

[Where problems could occur]
I didn't see any other patch that claims to be a fix of this one in
the upstream tree. The problem I think of for the moment is that we
might see other failures when using this in the future.
