RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Shaolong Hu 2014-03-21 10:10:08 UTC 
Description of problem:
--------------------------
kvm unit test "emulator" fails, current we plan to add kvm unit test to qemu-kvm test plan, we are aware this may be qemu, kvm or kvm unit test suite problem, put in qemu-kvm component first, this bug is to track the issue, for future tester reference.


Version-Release number of selected component (if applicable):
---------------------------------------------------------------
3.10.0-101.el7.x86_64
qemu-kvm-rhev-1.5.3-55.el7.x86_64

I think for RHEL7, qemu has no longer much difference from upstream, which in any chance affects kvm unit test, so i use our qemu-kvm "QEMU=/usr/libexec/qemu-kvm ./run_tests.sh" to run the test, but if i am wrong, please correct me.


How reproducible:
-----------------
100%

Steps to Reproduce:
----------------------
use "QEMU=/usr/libexec/qemu-kvm ./run_tests.sh" to run the test, will run into:

KVM internal error. Suberror: 1

Comment 2 Paolo Bonzini 2014-03-21 13:42:41 UTC 
The tests were added to cover instructions MOVAPS/MOVAPD.  These instruction have been backported to RHEL7 for bug 1052090.
