On a MX router running Junos Node Slicing using external server model of RHEL 7.3 on JDM 18.4R1-S6.3, after the Red Hat server updated the firmware driver and Bios, â€‹persistent error messages are observed.


Persistent error message observed:

Jan  7 20:31:30 customer-host libvirtd: 2731: error : virNetClientProgramDispatchError:177 : Cannot open log file: '/var/log/libvirt/qemu/dfwm2k02-SU1RI.log': Device or resource busy
