[Bug 2022892] [NEW] emulator in ubuntu_kvm_unit_test timeout with "jump to non-canonical address" test with J-realtime on openstack AMD64
Public bug reported:
emulator test in ubuntu_kvm_unit_test will timeout with J-realtime on
openstack amd64 instance. This issue can be seen after we start testing
on openstack with 5.15.0-1036.39 in sru-20230320.

Bump the timeout to 180 seconds does not help. This issue still exist
with the latest upstream kvm-unit-tests code (02d8befe99f8)
It's the test_jmp_noncanonical() test in test_emulator_64() that cause
this hang. Comment it out can make this test finish properly.
It's worthy to note that this test has passed with j/ibm on openstack
amd64.

qemu-system-x86_64: terminating on signal 15 from pid 9798 (timeout)
FAIL emulator (timeout; duration=90s)
Bump the timeout to 180 seconds does not help. This issue still exist
with the latest upstream kvm-unit-tests code (02d8befe99f8)
It's the test_jmp_noncanonical() test in test_emulator_64() that cause
this hang. Comment it out can make this test finish properly.
It's worthy to note that this test has passed with j/ibm on openstack
amd64.
