1076213 – (v2v_openstack_target) OpenStack as a v2v target.

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.

Description Stephen Gordon 2014-03-13 19:13:24 UTC

Description of problem:

Customers with an existing investment in alternate hypervisors have expressed an interest in being able to extract an instance with OpenStack as the target, with the intent to then run on KVM hosts.

This type of migration is theoretically possible today via v2v to a KVM host and then manually injecting the image into glance or possibly more likely as a volume in cinder but it would be useful to streamline this procedure.

Comment 1 Stephen Gordon 2014-06-20 14:23:26 UTC

Comment 4 Stephen Gordon 2014-08-30 02:45:26 UTC

After some further discussion via email it's clear we have two use cases to facilitate ideally:

- Migration of a VMware image to Glance to run on OpenStack-managed ESXi hypervisors (via the Nova vCenter driver).
- Migration of a VMware image to Glance to run on OpenStack-managed KVM hypervisors (via the Nova Libvirt driver).

In the case of the former additional image properties need to be set:

For this case, just use tar + qemu-img convert + glance image-create.
virt-v2v is not involved.

For the second case, virt-v2v sets the properties.

For the first case, you could use image inspection, using the tool
virt-inspector + some xpath scripting.

Comment 6 Richard W.M. Jones 2014-09-30 14:48:30 UTC

virt-v2v in RHEL 7.1 and Fedora >= 21 support the -o glance
option which writes the converted guest to glance.

http://libguestfs.org/virt-v2v.1.html#convert-disk-image-to-openstack-glance

Note this is only suitable when the guest will be booted
on KVM (because virt-v2v converts to KVM).  If the guest is
to be booted on ESXi hypervisors managed by OpenStack then
you would not want to involve virt-v2v.

Comment 7 Scott Radvan 2014-12-11 23:37:31 UTC

See the following article which covers this topic:

https://access.redhat.com/articles/1247463

"Converting VMware guests to Red Hat Enterprise Linux OpenStack Platform"

Comment 8 Richard W.M. Jones 2014-12-16 15:00:30 UTC

This bug is assigned to me, but I don't know what there is to do.

The customer can already try the preview packages we've been
distributing since May 2014 by following the instructions here:

https://www.redhat.com/archives/libguestfs/2014-May/msg00090.html

The -o glance option exists and is tested by QA, so we have a high
confidence it should just work for them.

The virt-v2v package will be Tech Preview in RHEL 7.1, and supported
at some point in RHEL 7 after that.

Comment 9 Stephen Gordon 2014-12-18 22:06:21 UTC

> This bug is assigned to me, but I don't know what there is to do.

Ship it, primarily. This RFE was raised because at the time this functionality did not exist in the tool (preview or otherwise). Normally we would track this through to completion and attachment to the errata (including QE verification of this RFE) - as the reporter I'm not sure how to answer the question as I don't see that I have done anything outside of normal RHEL process?

Comment 10 Richard W.M. Jones 2014-12-18 23:27:25 UTC

Tingting, could you please QA ACK this bug so I can add it
to the erratum.  The RFE is already fixed because we support
'-o glance' in libguestfs-1.28.1-1.18.el7 so no extra QA
is required.

Comment 11 Richard W.M. Jones 2014-12-18 23:28:48 UTC

For cinder import specifically, refer to bug 1155229.

Comment 16 zhoujunqin 2015-01-27 10:41:45 UTC

Test with ova file exported from esx server since esx server license expired.

Packages:
libguestfs-1.28.1-1.18.el7.x86_64

1. Export guest ova image from esx server.

Scenario 1:Test with rhel guest's ova file:

1.2 Use virt-v2v convert guest with "-i ova" option.
