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.

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". Upstream commits: https://github.com/libguestfs/libguestfs/commit/bae3d92e88b7e74af11a5d0905710cf00f2504e3 https://github.com/libguestfs/libguestfs/commit/6200ae7204f4db3b93707acf7356083e121f854f I can reproduce it with builds:

[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
