Description of problem: Missing source path attribute for char device Version-Release number of selected component (if applicable): virt-manager-1.5.0-1.el7.noarch How reproducible: 100% Steps to Reproduce: 1. Prepare a guest with below unix channel. <channel type='unix'> <source mode='bind' path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> 2.

Upstream commit: commit 931936a328d22413bb663e0e21d2f7bb111dbd7c Author: Pavel Hrdina <phrdina> Date: Thu Jun 28 16:18:43 2018 +0200 virtinst: Remove only auto-generated channel source path
Hi,Pavel Is this bug targeted for rhel7.6 since I see rhel-7.6.0+ flag is set, if so when will you plan to build the new virt-manager package including fix of this bug,thanks. BR, juzhou.
I can reproduce this issue with package: virt-manager-1.5.0-1.el7.noarch Then try to verify this bug with new build: virt-manager-1.5.0-3.el7.noarch virt-install-1.5.0-3.el7.noarch libvirt-4.5.0-12.el7.x86_64 qemu-kvm-rhev-2.12.0-26.el7.x86_64 libvirt-python-4.5.0-1.el7.x86_64 Steps: 1. Prepare a guest with below unix channel. <channel type='unix'> <source mode='bind' path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> 2. Clone the guest. #virt-clone -o rhel7.6 --debug --auto-clone Allocating 'rhel7.6.qcow2' | 7.0 GB 03:57 Clone 'rhel7.6-clone' created successfully. 3 Check unix channel of new guest in xml file. #virsh dumpxml rhel7.6-clone | grep channel <channel type='unix'> <source mode='bind' path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> Results: 1. The clone finishes with source path on xml file and new guest starts successfully. 2. The none auto-generated channel source path '/tmp/guestfwd' keeps during cloning. I move this bug from ON_QA to VERIFIED based on above testing.
