Proxmox VE 5.2 - amd64-microcode

[ymir]

Is there a reason why Proxmox VE (5.2) don't include the amd64-microcode package?

(system: supermicro h8scm-f, 64GB reg ECC)

 

[spirit]

it's available in debian non-free repository.

thanks,

are there any reasons not to activate the repo (and the AMD microcode updates) in Proxmox VE...

just for info:

since, as of today, the debian stretch non-free repo contains a very old (3.20160316.3) amd64-microcode version - so I used stretch-backports to get a more recent version (3.20180524.1~bpo9+1):

1.) add non-free backports security updates to sources
deb http://ftp.debian.org/debian stretch-backports non-free

2.) update repo
apt-get update

3.) install AMD64 microcode
apt-get -t stretch-backports -y install amd64-microcode

4.) reboot

info on the operating environment:
While updating I used live system migration for all running VMs (various Linux and Windows servers and workstations).
All VM disks are located on serveral external NFS storage servers (so I don't know if there is any impact on Proxmox internal or distribute storage),

So far I all VMs on a three systems cluster are continuing running without problems (most VMs are configured with CPU type Opteron_G3 or Opteron_G4, a few with kvm64)

Just for convenience - the attached "amd64-microcode.zip" file contains two files:
a) "debian-non-free.list" ... to be placed in /etc/apt/sources.list.d
b) "install-amd64-microcode.sh" ... a script to automate the update and install process (note: the file doesn't have any execute attributes - add them to activate the script)

CPUINFO after installing the microcode package and the reboot:

cat /proc/cpuinfo

the package is in the non-free repo, which is not enabled by default.
