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.

2.Check machine type in guest.
#wmic csproduct get Version

3.Downgrade qemu-kvm version to RHEL.7.1 GA version
qemu-img-rhev-2.1.2-23.el7.x86_64

4.Boot up guest with the same CLI.

5.Check machine type in guest.
#wmic csproduct get Version

Actual results:
after step2.
Version
pc-i440fx-rhel7.0.0

after step 5.
Version
RHEL 7.0.0 PC (i440FX + PIIX, 1996)

Expected results:

after step2 ,the result should be:
Version
RHEL 7.0.0 PC (i440FX + PIIX, 1996)

Comment 4 Miroslav Rezanina 2015-07-09 10:59:35 UTC 
There's no change in machine type setup. However, description value is used for 2.1.2 version, name value is used fo 2.3.0 version.
Comment 5 xiagao 2015-07-10 09:04:31 UTC 
sorry, update qemu CLI:

     -machine pc-i440fx-rhel7.0.0 

instead of: 

     -machine pc

2.Check machine type in guest.
#wmic csproduct get Version

3.Downgrade qemu-kvm version to RHEL.7.1.z version
qemu-kvm-rhev-2.1.2-23.el7_1.4.x86_64

4.Boot up guest with the same CLI.

5.Check machine type in guest.
#wmic csproduct get Version

Actual results:
after step2.
Version
pc-i440fx-rhel7.0.0

after step 5.
Version
RHEL 7.0.0 PC (i440FX + PIIX, 1996)
Comment 9 huiqingding 2015-07-21 03:41:44 UTC 
Verify this bug using the following version:
qemu-kvm-rhev-2.3.0-12.el7.x86_64
kernel-3.10.0-292.el7.x86_64

Use the same test steps of comment #8,  after step 2, the output is same as step 5:
Version
RHEL 7.0.0 PC (i440FX + PIIX, 1996)
