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the product is no longer active in Red Hat Bugzilla.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.
The command:
virsh save winsrv testsavefile
get an error like: QEMU «migrate»: An undefined error has ocurred
if the config file to remove the block containing:
<hostdev mode='subsystem' type='usb' managed='yes'>
<source>
<address bus='2' device='3'/>
</ source>
</ hostdev>
and then:
virsh save winsrv testsavefile
saves the file without errors.
libvirt-python-0.9.4-23.el6_2.7.x86_64
libvirt-client-0.9.4-23.el6_2.7.x86_64
libvirt-0.9.4-23.el6_2.7.x86_64
qemu-kvm-0.12.1.2-2.209.el6_2.4.x86_64
The unhelpful error message is coming from qemu. I'm not sure it makes any sense to save/restore a domain with host devices assigned (I'm afraid they the devices will be in different internal state when the domain is resumed) but I will reassign this to qemu-kvm for now to check what's going on...
Could you attach /var/log/libvirt/qemu/winsrv.log file, which contains the command line qemu-kvm was started with and hopefully also some more messages from qemu.
save/restore of domains with assigned devices is not supported. The error message is not friendly, but this is not critical and has been improved on upstream (so RHEL7 will have it right).
Closing bug as deferred because the "undefined error" will be fixed in RHEL7 (although the use case will still be invalid).
