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 Adit Ranadive 2017-05-23 23:49:55 UTC
1. Feature Overview:
 a) Name of feature:
 VMware Paravirtual RDMA User Library (libvmw_pvrdma).

 b) Feature Description:
 VMware recently added a paravirtual RDMA device to vSphere 6.5. We have also 
 upstreamed the driver for Linux with Linux Kernel 4.10 as well as the user library. 
 This feature request is to add the corresponding user library from upstream rdma-
 core repository to RHEL-based Guest Operating Systems. 

2. Feature Details:
 a) Architectures:
    64-bit Intel EM64T/AMD64

 b) Bugzilla Dependencies:
    1454965.

 c) Drivers or hardware dependencies:
    rdma-core. PVRDMA Driver.

 d) Upstream acceptance information:
    Present as a new provider in rdma-core release v13. Commit 	
    b6b0734abcceb167c2820e96f0891b6cae7b59e9.

 e) External links:
 https://github.com/linux-rdma/rdma-core/tree/master/providers/vmw_pvrdma

 f) Severity (H,M,L): H

 g) Feature Needed by:
 RHEL 7.4 GA. This feature would allow VMware customers to deploy and use RHEL-based 
 VMs with PVRDMA devices. The library would allow guest user-space applications to 
 bypass the guest OS when issuing RDMA operations to the PVRDMA device.

 3. Business Justification:
 Same as above.

Comment 2 Honggang LI 2017-05-25 02:57:10 UTC
libvmw_pvrdma had been imported to rdma-core-13-5.el7.

rpm -qpl libibverbs-13-5.el7.x86_64.rpm | grep vmw_pvrdma
/etc/libibverbs.d/vmw_pvrdma.driver
/usr/lib64/libibverbs/libvmw_pvrdma-rdmav2.so

Comment 3 Adit Ranadive 2017-05-25 03:00:22 UTC
Great thanks!

Comment 4 John Shortt 2017-05-26 13:36:42 UTC
This request came in long after the planning and development phases for 7.4. The criteria for taking in a new driver has not been met.  Please work with your engineering partner manager to get this criteria satisfied for a future version of RHEL.

This will not be supported in 7.4.

Thank you

Comment 5 Jarod Wilson 2017-06-07 19:40:16 UTC
The component was correct, putting it back to rdma-core.

Comment 6 John Jarvis 2017-07-27 20:47:51 UTC
Flagged for review for inclusion in RHEL 7.5.
