From e0e4f01c6f4fb5881960f72ae4e80951b711131e Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Thu, 24 Mar 2022 16:04:57 +0100 Subject: [PATCH 1/5] RHEL: disable "seqpacket" for "vhost-vsock-device" in rhel8.6.0 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Stefano Garzarella RH-MergeRequest: 136: RHEL: disable "seqpacket" for "vhost-vsock-device" in rhel8.6.0 [rhel-8.7.0] RH-Commit: [1/1] d82ea09e123679521503689f7d9af1c03dc71bfc RH-Bugzilla: 2068202 RH-Acked-by: Jason Wang RH-Acked-by: Eugenio Pérez RH-Acked-by: Dr. David Alan Gilbert RH-Acked-by: Stefan Hajnoczi vhost-vsock device in RHEL 8 kernels doesn't support seqpacket. To avoid problems when migrating a VM from RHEL 9 host, we need to disable it in rhel8-* machine types.
