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.

Virt-v2v needs to run on the latest Red Hat Enterprise Linux release
to ensure it can correctly read and modify new guest filesystem
features.  A new version of virt-v2v is now available for RHEL 7.1.

Before RHEL 7.1 is released, follow the instructions here to
install unsupported preview packages on top of RHEL 7.0:
https://www.redhat.com/archives/libguestfs/2014-May/msg00090.html

After RHEL 7.1 is released, virt-v2v will be available in
Technical Preview.

You can run virt-v2v in a single virtual machine.  Other
requirements are covered here:
http://libguestfs.org/virt-v2v.1.html#resource-requirements

If you find a missing feature or bug in the new version of virt-v2v
please file a bug using the following link:
https://bugzilla.redhat.com/enter_bug.cgi?product=Red%20Hat%20Enterprise%20Linux%207&component=libguestfs
