Opzet[edit]

Installatie van de host[edit]

De installatie is gedaan met behulp van de CFEngine3 policies uit de CFEngine Roadshow.

Issues[edit]

pve-manager[edit]

De installatie liep stuk op een dependency in proxmox-ve van pve-manager. De configuratie van pve-manager ging fout in de postinstall. De oplossing is om de postinstall bestanden te verwijderen. [https:s://forum.proxmox.com/threads/installation-completely-broken.46796/#post-221228 Verwijderen postinstall bestand]

Ethernet configuratie[edit]

Probleem: Connectie gaat verloren Oplossing: ethtool -K eth0 tx off rx off

Community version[edit]

De apt-cacher-ng heeft een bijzondere voorziening nodig voor met https repositories, dat geldt alleen voor de enterprise versie van Proxmox. Dus verwijder deze repository. 

root@host:~# rm sources.list.d/pve-enterprise.list

Technische oplossingen[edit]
