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.

Can't set '-of qcow2 -oa preallocated' in v2v rhv-upload conversion on rhel8

Version-Release number of selected component (if applicable):
virt-v2v-1.42.0-9.module+el8.4.0+9561+069bb9c1.x86_64

Steps to Reproduce:
1.Use v2v to convert guest from VMware to rhv via rhv-upload and set '-of qcow2 and -oa preallocated' in command line

Actual results:
As above description

Expected results:
Can set '-of qcow2 -oa preallocated' in v2v rhv-upload conversion on rhel8

Additional info:
1. Can set '-of qcow2 -oa sparse' in v2v rhv-upload conversion on rhel8

Comment 1 Richard W.M. Jones 2021-03-16 13:56:03 UTC 
In RHEL 7 and RHEL 8 we carried the following patch:

https://github.com/libguestfs/virt-v2v/commit/c8800b9c8a7c7d95fca0329bcce35e60b14effbd

This never went upstream, so it need to either be copied to RHEL 9,
or better still let's sort out the upstream status.

Adding this to the pile of things to fix in virt-v2v.
Comment 3 Eric Hadley 2021-09-08 16:49:18 UTC 
Bulk update: Move RHEL-AV bugs to RHEL9. If necessary to resolve in RHEL8, then clone to the current RHEL8 release.
Comment 4 Xiaodai Wang 2022-06-14 06:28:26 UTC 
Update about this bug:

This is the latest test result of the combination of '-of' and '-oa'.

-of raw   -oa sparse         not supported, see bz1600547
-of raw   -oa preallocated   success on rhel8.6, failed on rhel9.1(bug?)
-of qcow2 -oa sparse         success on rhel9.1
-of qcow2 -oa preallocated   success on rhel9.1

For the '-of raw -oa preallocated', Is it a new bug? It was success in RHEL8.6.

Hi xiaodai, the problem you encountered should be bug 1939423 - V2V can't set '-oa preallocated' in rhv-upload conversion on rhel9
Comment 7 Richard W.M. Jones 2022-06-14 09:32:55 UTC 
I'm a bit confused about whether this is working or not on RHEL 9.1.

However the basic problem is this error from RHV (see the debug log):

ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Cannot add Virtual Disk. Disk configuration (RAW Sparse backup-None) is incompatible with the storage domain type.]". HTTP response code is 409.

Unfortunately there is no way for us to tell if particular combinations
will work, and RHV closed the bug where we asked them to provide that
information (https://bugzilla.redhat.com/show_bug.cgi?id=1829009).
Comment 8 Laszlo Ersek 2022-07-07 08:44:41 UTC 
Based on comment 7, and on a more recent off-list discussion with Rich et al, closing this as CANTFIX.
