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.

Comment 12 Yang Yang 2014-05-20 04:01:57 UTC 
Verified this bug on libvirt-0.10.2-36.el6.x86_64
qemu-kvm-rhev-0.12.1.2-2.426.el6.x86_64
libvirt-0.10.2-36.el6.x86_64

Steps:
1. restore the guest from the non-exist file
# virsh restore /tmp/test
error: Failed to restore domain from /tmp/test
error: Failed to open file '/tmp/test': No such file or directory

2. save the guest to the non-exist file
# virsh save qcow3 /tmp/test/qcow3.save
error: Failed to save domain qcow3 to /tmp/test/qcow3.save
error: Failed to create file '/tmp/test/qcow3.save': No such file or directory

3. save the guest to the right file and the guest can be restored successfully
# virsh save qcow3 /tmp/qcow3.save
Domain qcow3 saved to /tmp/qcow3.save

# virsh restore /tmp/qcow3.save 
Domain restored from /tmp/qcow3.save

Since the reported error messages are clear, so I'd like to change the status to verified.
