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).

Description of problem:
libvirt restore guest fail with low probability and report qemu-kvm smbios error.
virsh restore $guest fail. but if you try again , it will be successed .
libvirt-0.9.8-1.el6.x86_64 can not reproduce this bug so it is a regression
Version-Release number of selected component (if applicable):
libvirt-0.9.9-2.el6.x86_64
qemu-kvm-0.12.1.2-2.222.el6.x86_64
How reproducible:
about 5%
Steps to Reproduce:
1. define a guest with xml like (RHEV's guest has smbios setting ) :
...
<sysinfo type='smbios'>
<system>
<entry name='manufacturer'>Red Hat</entry>
<entry name='product'>RHEV Hypervisor</entry>
<entry name='version'>6Server-6.2.0.3.el6</entry>
<entry name='serial'>44454C4C-4A00-1047-804A-C2C04F4D3258_00:23:19:2D:52:90</entry>
<entry name='uuid'>b075feff-dfb5-6b29-3734-e0aa0d8ed56a</entry>
</system>
</sysinfo>
<os>
<type arch='x86_64' machine='rhel6.2.0'>hvm</type>
<boot dev='hd'/>
<boot dev='network'/>
<bootmenu enable='yes'/>
<smbios mode='sysinfo'/>
</os>
...
2. create this guest
# virsh create ruth.xml
3. let guest save and restore in the loop
#while true ;do virsh save rr62 /tmp/save && virsh restore /tmp/save ;done
note: when virsh restore fail error is :
error: Failed to restore domain from /tmp/save
error: unsupported configuration: the QEMU binary /usr/libexec/qemu-kvm does not support smbios settings
4.in the same time watch the libvirt log , then restore fail the error show up
#tail -f /var/log/libvirt/libvirtd.log
...
2012-02-08 05:55:46.241+0000: 29371: error : qemuBuildCommandLine:3681 : unsupported configuration: the QEMU binary /usr/libexec/qemu-kvm does not support kvm
2012-02-08 05:55:46.241+0000: 29371: error : qemuBuildCommandLine:3815 : unsupported configuration: the QEMU binary /usr/libexec/qemu-kvm does not support smbios settings
....
RUTH test can reproduce this issue 100%
#ruth -ld -vvv ../config/vmTests-new.conf -f vmTests.HibernateVmTests.repeatedHibernationCycle
result is fail the log is the same with pure libvirt .
Actual results:
virsh restore fail
Expected results:
no fail
Additional info:
this issue is hard to reproduce with pure libvirt ,but it can reproduce easily with RUTH
I test it using libvirt-0.9.10-0rc2.el6.x86_64 in pure libvirt environment 300 tims save and restore and can not reproduce this issue ,
so I close it with currentrelease .
