Initial Setup

TODO

1. See Debian Server: Initial Setup.
   • TODO: Differences.
2. Setup the PVE repos (assuming no subscription):
   • In /etc/apt/sources.list.d/pve-enterprise.list, comment out the Enterprise repo.
   • In /etc/apt/sources.list, add the PVE No-Subscription repo. See Package Repositories.
   • Update the package index.
3. Disable the console MOTD:
   • Disable pvebanner.service.
   • Clear or update /etc/issue (e.g. use use the logo).
4. Disable IPv6 NDP (TODO Move to Debian?):
   • It's enabled on all bridges by default, meaning the node may become accessible to untrusted bridged networks even when no IPv4 or IPv6 addresses are specified.
   • TODO
   • Reboot (now or later) and make sure there's no unexpected neighbors (ip -6 n).

Setup SPICE Console

1. In the VM hardware configuration, set the display to SPICE.
2. Install the guest agent:
   • Linux: spice-vdagent
   • Windows: spice-guest-tools
3. Install a SPICE compatible viewer on your client:
   • Linux: virt-viewer

Cluster

• /etc/pve will get synchronized across all nodes.
• High availability:
  • Clusters must be explicitly configured for HA.
  • Provides live migration.
  • Requires shared storage (e.h. Ceph).

Simple Setup

1. Setup a management network for the cluster.
   • Either isolated or firewalled with internet access.
2. Setup each node.
3. Add each other host to each host's hostfile.
   • So that IP addresses can be more easily changed.
   • Use short hostnames, not FQDNs.
4. Create the cluster on one of the nodes: pvecm create <name>
5. Join the cluster on the other hosts: pvecm add <name>
6. Check the status: pvecm status
