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 vivian zhang 2014-12-17 07:10:15 UTC 
Description:
migration failed with error when configure guest with OVMF bios + machine type=rhel6.5.0
when machine type is set lower than rhel6.5.0, such as rhel6.4.0, migration failed with the same error.

Product version
libvirt-1.2.8-10.el7.x86_64
qemu-kvm-rhev-2.1.2-15.el7.x86_64
OVMF-20140822-7.git9ece15a.el7.x86_64

How producible
100%

Steps:
1. Prepare a migration env with nfs img between source and target host

2. make sure source and target host has been installed OVMF
# rpm -q OVMF
OVMF-20140822-7.git9ece15a.el7.x86_64

3. install a UEFI guest with virt-manger, make sure the guest with below configuration, set machine type='rhel6.5.0', and OVMF bios in guest xml

# virsh dumpxml rhel7new
...
<os>
    <type arch='x86_64' machine='rhel6.5.0'>hvm</type>
    <loader readonly='yes' type='pflash'>/usr/share/OVMF/OVMF_CODE.fd</loader>
    <nvram template='/usr/share/OVMF/OVMF_VARS.fd'>/var/lib/libvirt/qemu/nvram/rhel7new_VARS.fd</nvram>
    <boot dev='hd'/>
  </os>
...

4. start guest, it works well
# # virsh list --all
 Id    Name                           State
----------------------------------------------------
 27    rhel7new                       running

5. do migration for this guest, met qemu-kvm error
# virsh migrate rhel7new --live qemu+ssh://10.66.6.205/system --verbose
root.6.205's password:
Migration: [100 %]error: internal error: early end of file from monitor: possible problem:
RHEL-6 compat: ich9-usb-uhci1: irq_pin = 3
RHEL-6 compat: ich9-usb-uhci2: irq_pin = 3
RHEL-6 compat: ich9-usb-uhci3: irq_pin = 3
qemu-kvm: /builddir/build/BUILD/qemu-2.1.2/savevm.c:906: shadow_bios: Assertion `bios != ((void *)0)' failed.

6. when modify machine type to pc-i440fx-rhel7.1.0 or pc-i440fx-rhel7.0.0, migration could success

7. when delete OVMF bios configuration <nvram template='/usr/share/OVMF/OVMF_VARS.fd'></nvram>, migration could also success

Actual result:
migration failed with error

Expected result:
migration should success when configure guest with OVMF bios + machine type=rhel6.5.0

Additional info:
similar issue refer bug 1170093, but that patch not fix this bug, so filed a new to track this issue
Comment 2 Laszlo Ersek 2014-12-17 08:31:00 UTC 
OVMF is completely unsupported on the rhel6.5.0 machine type.
Comment 11 Miroslav Rezanina 2015-03-19 09:08:22 UTC 
Fix included in qemu-kvm-rhev-2.2.0-8.el7
Comment 12 Xiaoqing Wei 2015-03-19 10:11:48 UTC 
with qemu-kvm-rhev-2.2.0-8.el7

machine types from 6.0.0 - 6.6.0 all fail to start VM w/ pflash.

pc and pc-i440fx-rhel7.0.0, and pc-i440fx-rhel7.1.0 success
