1308769 – virt-v2v does not copy additional disks to Glance

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.

Doc Type:	Bug Fix
Doc Text:	With this update, virt-v2v is capable of exporting guests with more than one disk to the OpenStack Glance service, while previously, only guests with a single disk could be exported. This makes it possible for larger virtual deployments to be converted to OpenStack Glance using virt-v2v.

Comment 5 Richard W.M. Jones 2016-02-16 16:03:41 UTC

For QA, I tested this by creating a CentOS guest:

$ virt-builder centos-6.img

Then I created a second empty disk:

$ truncate -s 1G centos-6-2.img

Then I created some libvirt XML to describe the guest.  See
http://libguestfs.org/virt-v2v.1.html#minimal-xml-for--i-libvirtxml-option

Then I imported the guest to Glance by doing:

$ virt-v2v -i libvirtxml centos-6.xml -o glance -of qcow2 -on test1

You should see 2 disks being created in Glance.  They will be called
"test1" and "test1-disk2".

I can reproduce it with builds:
libguestfs-1.28.1-1.55.el7.x86_64
virt-v2v-1.28.1-1.55.el7.x86_64
kernel:kernel-3.10.0-327.el7.x86_64    
virtio-win-1.8.0-4.el7.noarch

Verify it with builds:
libguestfs-1.32.4-1.el7.x86_64

[1107.5] Finishing off

Scenario2:Convert multidisks guest which has windows os from esx6.0 to openstack 
Scenario3:Convert multidisks guest which has linux os from XEN to openstack
Scenario4:Convert multidisks guest which has windows os from XEN to openstack
Scenario5:Convert multidisks guest which has linux os from KVM to openstack 
Scenario6:Convert multidisks guest which has windows os from KVM to openstack

7.After conversion, check the result on openstack dashboard
 Login the openstack dashboard
7.1 Check all disk which belong to the guest has list the image interface  
7.2 Make sure the guest can be boot successfully on openstack 
7.3 Create the other additional disks as volume 
7.4 Add volumes which created by step2.4 to instance which is you just converted 
7.5 Make sure the instance is normal and the new added volumes could be used in OS
7.6 Check the guest whether or not meet checkpoint 

Result now:
As above all scenarios can be converted successfully and checking conversion result at openstack is passed,virt-v2v can copy additional disks to Glance
So move the bug from ON_QA to VERIFIED
