Bug Description

Series: Disco
Arch: i386
Kernel: 5.0.0-38.41-generic

All of the tests appear to fail with an Unhandled cpu exception. This appears to break all of the vmexit tests in kvm_unit_tests

Found on T-3.13.0-189.240 i386 node pepe (didn't not fail on i386 node fozzie, probably caused by HW difference)
