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 2 Suzanne Logcher 2011-03-28 20:30:05 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains 
unresolved, it has been rejected as it is not proposed as an 
exception or blocker.  It has been moved to RHEL 6.2 since 
it is a FutureFeature request.
Comment 3 Tim Jackson 2011-04-14 13:11:36 UTC 
I haven't tested it yet, but according to http://libvirt.org/news.html , support for "qemu: live migration with non-shared storage for kvm" was added in libvirt 0.8.2, and it appears that the RHEL6.1 beta includes libvirt 0.8.7.
Comment 4 Bhavna Sarathy 2011-05-25 20:53:08 UTC 
Can the customer test RHEL6.1 and report if this feature is available in current release?

    virsh: Better document --copy-storage migrate options
    
    Both --copy-storage-{all,inc} options require disk images to be present
    on destination host.

and sent for internal review:

Comment 17 weizhang 2011-09-29 08:58:44 UTC 
Verify pass on
kernel-2.6.32-202.el6.x86_64
libvirt-0.9.4-14.el6.x86_64
qemu-kvm-0.12.1.2-2.192.el6.x86_64

check the man virsh, we can see
...
 In both cases the disk images have to exist on destination host, the --copy-storage-...options only tell libvirt to transfer data from the images on source host to the images found at the same place on the destination host.
...

Steps:
1. do #iptables -F  on both hosts
2. start a guest on source host with no shared image
# virsh start guest
3. create a empty image on target host with the same size, directory and name as in source host
# qemu-img create /IMAGE_DIR/guest.img IMAGE_SIZE
4. do migration on source host 
# virsh migrate --live rhel6-1 qemu+ssh://10.66.85.202/system --copy-storage-all
5. after migration, the domain is running on target host.
