Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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.

Actual results:
error occurs when doing the unittests

Expected results:
unitttest should return successfully.

Additional info:

Comment 1 xhan 2013-12-31 06:14:37 UTC

the unittest is from the link: 
git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests

Comment 3 Marcelo Tosatti 2014-01-02 12:48:22 UTC

Can you please execute the test as described by line 18 of the README file?

https://git.kernel.org/cgit/virt/kvm/kvm-unit-tests.git/tree/README

Comment 4 xhan 2014-01-09 05:04:15 UTC

Using qemu (supported since qemu 1.3):
qemu-system-x86_64 -enable-kvm -device pc-testdev -serial stdio -device isa-debug-exit,iobase=0xf4,iosize=0x4 -kernel ./x86/msr.flat

Do you mean test this with upstream qemu?

No, i mean use that qemu-kvm parameter list instead of the parameter list 
of section "Steps to Reproduce" of comment #1.

But still use the qemu-kvm binary from RHEL7.

Comment 6 xhan 2014-01-13 07:56:45 UTC

sieve.flat and rmap_chain.flat cases passed.
pmu test failed:

qemu-kvm -enable-kvm -device pc-testdev -serial stdio -kernel x86/pmu.flat 

error returned: unhandled excecption 13

packages version:
qemu-kvm-rhev-1.5.3-34.el7.x86_64

Comment 7 Marcelo Tosatti 2014-01-14 19:44:06 UTC

Should use -cpu host.

Comment 8 xhan 2014-02-14 07:06:02 UTC

Test with -cpu host for pmu case still failed.

qemu-kvm -enable-kvm -device pc-testdev -serial stdio -kernel pmu.flat -cpu host 
VNC server running on `::1:5900'

Works for me with the following command line:

qemu-system-x86_64 -enable-kvm -device pc-testdev -serial stdio -device isa-debug-exit,iobase=0xf4,iosize=0x4 -kernel ./x86/pmu.flat -cpu host
