I have a couple of VMs I want to communicate by themselves on a single LAN segment, using a new VLAN ID. Will the PVE host act like a VLAN aware switch without having any other external networking for this VLAN?

I'm trying to wrap my head around the CPU instruction sets exposed by Qemu (KVM?). It seems that the default selected cpu of kvm64 seems like a poor choice for a remotely modern CPU, and now causes issues with RHEL 9 OSes: https://www.qemu.org/docs/master/system/i386/cpu.html...

I was reading here when I was deciding to configure IPv6 on my pve server: https://pve.proxmox.com/wiki/Firewall And there is this: "If you enable the firewall, traffic to all hosts is blocked by default. Only exceptions is WebGUI(8006) and ssh(22) from your local network.". However, it seems...

I've been trying to configure a site tunnel to HE.net on an Almalinux 9.1 container. I get the following message: modprobe: FATAL: Module ipv6 not found in directory /lib/modules/5.15.83-1-pve add tunnel "sit0" failed: No such device will loading with "modprobe sit" load the appropriate...

I changed my node IP address yesterday, and while poking around today I noticed the datacenter and node network config displays differ. The old address was 192.168.10.180, and the new is 192.168.10.40. I did not reboot yet and I suspect that this will resolve with a reboot. I haven't attempted...

I'm having trouble with maintaining two backup routines. My original goal was to have two plans: one backs up all VMs/containers nightly using "snapshot" mode so that any users are not directly impacted on a daily basis. I also wanted to run a plan weekly using "stop" mode so that I know I have...

I feel really daft for not seeing anything or not asking earlier...I don't have a subscription (shame on me) but I'm assuming that only applies to PVE and related packages? The core functions of the host OS from the PVE installer still applies updates, correct? Or do I need to disable the...

The default settings for container creation (I don't think I changed any defaults) is the following: I have been assuming that the check mark beside Firewall means that the container firewall will be enabled after creation. However, this is never the case, and I always need to enable it...

So I love PVE and it has done a great job putting together a virtualisation environment. All the servers and containers I run are entirely non-commercial (i.e. no income) and 99% personal interest and learning. Is there any way I can provide meaningful support for PVE aside from the Enterprise...

For Windows, it seems pretty straight forward: select your version, and the configuration changes accordingly. For Linux, it seems that the base hardware of SeaBIOS, kvm64, and i440fx is selected for anything beyond kernel 2.4. However, I noticed that RHEL 9 and derivatives need the cpu set to...

I would have expected the VM id to behave something like a database primary key and keep going up without filling in any gaps. Why are ids reused after a VM (or LCX) is removed and purged?

I'm trying to enable the firewall at the node level, and found I sometimes needed to navigate away from the settings for them to take effect, or I've had to disable/enable the firewall again. What is the correct way to force firewall rules applied through the gui? Note: I'm not familiar (yet)...

Is it possible to inject a config file into the PVE ISO installer, so it could boot and configure itself automatically, sort of like a cloud-init install? It would be nice to setup network, user account, storage, etc. At the end after booting from the ISO, you would then just reboot and login...
