Update repositories
You will get an error during the update:
Err:4 https://enterprise.proxmox.com/debian/pve buster InRelease
401 Unauthorized [IP: 144.217.225.162 443]
It comes from /etc/apt/sources.list.d/pve-enterprise.list:
root@pve02:/etc/apt/sources.list.d# cat pve-enterprise.list
deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise
You can disable it in the GUI and add there ‘No Subscription’ option. Alternatively, change it to (mind version specific buser below):
root@pve02:/etc/apt/sources.list.d# cat pve-enterprise.list
# deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise
And then:
root@pve02:/etc/apt# cat sources.list
deb http://ftp.us.debian.org/debian buster main contrib
deb http://ftp.us.debian.org/debian buster-updates main contrib
# security updates
deb http://security.debian.org buster/updates main contrib
# PVE pve-no-subscription repository provided by proxmox.com,

watch -n 1 sensors
or just

Involves:
- changing boot command line
- adding kernel modules to load and, possibly, blacklist
See gpu-passthrough.md.
Grub
in /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt intel_pstate=disable"
where intel_pstate=disable needed to manage power.
Then:
# update-grub
VFIO Modules
Edit /etc/modules:
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
Add the server to Datacenter/Cluster
Make sure the host has:
- unique host name
- networking is defined - can’t change after
- no VMs
Data Center Storage
Add connection to the NFS server: Datacenter\Storage Add NFS
Schedule Backups
Datacenter\Backup, Add
