Hi all, after I enable TLS option, the PMG only expose port 25 to public. How do I config Thunderbird then? Just indicate port 25 and no tls?

I'm trying to solve a very specific problem to get a Palo Alto VM-series firewall online on Proxmox (not supported by Palo Alto but should work fine in KVM). The VM itself works fine, but I'm trying to give it three specific network interfaces: One virtio interface for the dedicated management interface (net0, registered as eth0 in the VM), and then a PCI-Passthrough'd Intel 82576 PCI Express card with two NICs.

This issue is the Palo Alto VM will always take the NIC with the lowest PCI-ID...

I've noticed when creating an OSD on an HDD, it starts out showing about 10% usage, and stays about 10% higher? We are using an SSD for the DB and therefore WAL but it seems like it shouldn't count that...? Also, the size is shown lower in the OSD "details" than the OSD page in PVE.

All the SSD only OSDs start at 0%. In this cluster all the SSDs are ~13% used and the few HDDs are all ~23% used.

≪ Previous: proxmox-secure-boot-support removed??

Hi,

I came across the problem, that migration and replication does not work if the disk(s) are on a encrypted ZFS storage - which is not well documented by the way.

The problem arose since the ZFS export function in pve-storage use the -R option of zfs send and this option does not work with encrypted datasets unless you use -w as well. Since this is no option because we cannot transfer the data encrypted, since the target pool has a different encryption key etc., the question is why use...

The Proxmox installer does not provide the ability to set up an encrypted root with ZFS, so Debian with an encrypted ZFS root needs to be installed first, then Proxmox will be added on top. This guide covers some of the caveats of doing so.

First, follow the excellent guide written here by the authors of ZFS to install Debian: https://openzfs.github.io/openzfs-docs/Getting Started/Debian/Debian Bookworm Root on ZFS.html

Hello there!

I really like the idea of having the full root-filesystem encrypted using native ZFS encryption (only).
However, as I currently couldn't find any complete writeup on on this topic, here's what worked for me (with and without Secureboot on PVE 8.1):

1. Install with zfs (RAID0 for single-disk application)
2. Reboot into ISO > Advanced Options > Graphical, debug mode
3. Exit to bash with `exit` or Ctrl+D
4. Execute following commands:

Hi Folks,

I for any reason a Node will perform a (controlled) restart... no one of running VM's are migrated to best effort free node on cluster, even VM is in a HA group !

I think this is not the behavior intended by HA .
