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 Laszlo Ersek 2022-04-13 06:34:57 UTC 
+++ This bug was initially created as a clone of Bug #1685081 +++

Refer to <https://bugzilla.redhat.com/show_bug.cgi?id=1685081#c9> for details.

The openstack output module currently passes the "--non-bootable --read-write" options to the "openstack volume create" command. There is a bug in the "openstack" utility however itself (in the "python-openstackclient" package) where it assumes that the image creation API blocks, and as soon as it completes, the readonly and bootable flags can be tweaked with the APIs that exist for those purposes. The image creation API does not block however, and when the "openstack" command line utility tries to set the readonly & bootable flags, those APIs fail because image creation is still in progress. This results in an obscure error message on the virt-v2v standard error.

Given that "--non-bootable" and "--read-write" are both defaults for VM image creation, per <https://docs.openstack.org/python-openstackclient/yoga/cli/command-objects/volume.html>, work the symptom around by simply not passing these options.

Steps:
Scenairo1:
1.1 Prepare a v2v-appliance on OSP16 env and convert a linux guest from VMware to openstack by v2v on v2v-appliance

# virt-v2v -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 -it vddk -io vddk-libdir=/home/vddk7.0.3 -io  vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21  -ip /home/passwd esx7.0-rhel9.1-x86_64 -o openstack -oo server-id=v2v-appliance

[   3.9] Opening the source
[  15.7] Inspecting the source
[  26.1] Checking for sufficient free disk space in the guest
[  26.1] Converting Red Hat Enterprise Linux 9.1 Beta (Plow) to run on KVM
virt-v2v: This guest has virtio drivers installed.
[ 203.6] Mapping filesystem data to avoid copying unused and blank areas
[ 204.9] Closing the overlay
[ 205.2] Assigning disks to buses
[ 205.2] Checking if the guest needs BIOS or UEFI to boot
[ 205.2] Setting up the destination: -o openstack -oo server-id=v2v-appliance
[ 226.2] Copying disk 1/1
█ 100% [****************************************]
[ 524.2] Creating output metadata
[ 530.5] Finishing off

1.2 Launch the volume as instance after v2v conversion on OSP16 env, check guest and checkpoints of guest are passed


Scenario2:

2.1 Convert a windows guest from VMware to openstack by v2v on v2v-appliance
# virt-v2v -ic vpx://root.227.27/data/10.73.199.217/?no_verify=1 -it vddk -io vddk-libdir=/home/vddk7.0.3 -io  vddk-thumbprint=76:75:59:0E:32:F5:1E:58:69:93:75:5A:7B:51:32:C5:D1:6D:F1:21  -ip /home/passwd esx7.0-win2022-x86_64-uefi -o openstack -oo server-id=v2v-appliance

[   4.3] Opening the source
[  12.3] Inspecting the source
[  23.8] Checking for sufficient free disk space in the guest
[  23.8] Converting Windows Server 2022 Standard to run on KVM
virt-v2v: This guest has virtio drivers installed.
[  47.9] Mapping filesystem data to avoid copying unused and blank areas
[  50.1] Closing the overlay
[  50.4] Assigning disks to buses
[  50.4] Checking if the guest needs BIOS or UEFI to boot
virt-v2v: This guest requires UEFI on the target to boot.
