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 Stepan Broz 2023-03-29 10:21:56 UTC 
Description of problem:
hyperv-daemons create IPv6 configuration with a non-supported separate IPv6 prefix/netmask connection configuration option IPV6NETMASK.

Version-Release number of selected component (if applicable):
hyperv-daemons-0-0.34.20180415git.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
Define an IPv6 address with a prefix (netmask) of e.g. 120.

Actual results:
ifcfg file created with a non-supported IPV6NETMASK option.

Expected results:
The correct red hat ifcfg syntax is to supply a prefix length in IPV6ADDR with a slash:
 IPV6ADDR=<IPv6 address>[/<prefix length>]

Duplicate this bug to https://bugzilla.redhat.com/show_bug.cgi?id=2196469, since there are more discussions in bug #2196469 even this bug number is smaller than bug #2196469.

Thank you.
