VLAN tagging for host and guest

Hello,

I'm new here and, as expected, I have a question. :-)

Is it possible to tag the Proxmox host interface AND the guest interface?

Example:
The Proxmox server has only one network connection (Linux Bridge), which is tagged with VLAN ID 120.

On the guest system (Debian), three virtual network adapters should be created via the previously created Linux Bridge interface. These adapters should also be tagged with IDs 120, 121, and 122.

Is this possible, and if so, how? I've tried many...

When syncing, both groups are displayed in ProxMox, but only the list of users in the first user group...

PVE not displaying real HD space

Hi everyone,

I've recently reconfigured a node in my Proxmox VE cluster, switching from LVM to ZFS. However, I've noticed that PVE is not correctly displaying the used space on the server.

As shown in the attached screenshot, the web UI reports only 0.07% used (1.90 GiB of 2.67 TiB), but in reality, the usage is higher, as confirmed by the following CLI outputs:

Proxmox vms freeze only when using spice console

Hello. So I am running into an issue where my windows proxmox vms are completely freezing up randomly whenever I connect to them using the spice console on a windows device using remote viewer. I know that it only occurs when using the spice console because I do not encounter these freezes when I use rdp to establish a remote connection (as, again, these vms are all windows vms). I want to be in a position where I can better troubleshoot why this is happening. Are there logs on the host...

I want to automate the monitoring of my monitoring jobs. I am pushing the notifications via a webhook to a ntfy.sh system and am parsing the title to match the desired icinga service for the backup.

If a PVE system has multiple backup jobs to run every day, I don't see a "unique" identifier to know which job was run. e.g. by using the comment provided in the backup job comment field or by some other unique identifier. in the notification, neither in the webhook nor in the email, I see a...

Hi all,

recently i discovered that Proxmox now supports great feature - snippets, aka hookscript. Also, it has special content storage type - snippets to hold snippets.

But im curious how they can be used from Web GUI.

Do i need to create hookscript and store it on storage type "snippets" with a special name (vm name) ?
Or do i need to directly edit "vm.conf" files to include hookscript as i could not find any options in GUI.

If this option only supported from CLI and during...

Hi,

our users are complaining, that blacklisted email addresses are still present in the quarantaine email and put to their quarantaine instead of being rejected.

How can i change the PMG behaviour to reject user blacklisted email addresses instead of putting them to quarantaine?

How to clean "zombie" fencing request in pacemaker after disaster recovery of a 8.3 cluster

Hi,

I have a simple Proxmox 8.3 cluster with 3 nodes by Scaleway (ex-dedibox)
Due to server failure, I had to replace all the nodes (one after a hard crash), one after the other, keeping the cluster alive.

Now everything seems to be back to normal, but the pacemaker service still has these errors, like every second:

Windbg Remote Kernel debugging and Proxmox not working

Hello,

I have a Windows Server 2022 and Win11 VM running on Proxmox. I'm using Virtio drivers for Network, SATA, etc.
The VMs themselves are running fine.
For testing purposes I need to perform remote kernel debugging on those hosts.

The debugger host is a VM on an ESXi server, and the VMs on Proxmox are in the same VLAN/network like the debuggees.
As long as the debugee is also on ESXi or a physical machine on the same VLAN/network everything works perfectly.

When the debuggee is one...

Proxmox VE 8.3.1 Installation with no RTL8125 Drivers

I'm trying to install Proxmox 8.3.1 (latest) on a newer ASUS Z890 motherboard that uses the Realtek R8125 2.5Ge NIC and it's failing to get network connectivity. That PC has only the RTL8125 NIC thus I have no other options to get initial Internet connectivity. Proxmox 8.3.1 doesn't detect this NIC and install a driver nor does the latest Realtek 2.5Gbe driver kit (r8125-9.015.00.tar.bz2) procedure (via autorun.sh) work correctly as the make fails with the error below.

The host I have done it on is a test server before I roll the update out to production servers and after running the upgrade I have no networking. I have seen a number of users with the same issue also however I can't seem to fix the issue with suggestions provided from them posts. All of the pre-installation checks passed with no warnings.

Opt-in Linux 6.11 Kernel for Proxmox VE 8 available on test & no-subscription

We recently uploaded a 6.11 kernel into our repositories. The current 6.8 kernel will stay the default on the Proxmox VE 8 series, the newly introduced 6.11 kernel is an option.
The 6.11 based kernel may be useful for some (especially newer) setups, for example if there is improved hardware support that has not yet been backported to 6.8.
This follows our tradition of upgrading the Proxmox VE kernel to match the current Ubuntu version until we reach an (Ubuntu) LTS release, like the 6.8...

We want to assemble the following virtualization scheme.

I need advice on the scheme itself and how to properly organize reservations.

It is clear that Proxmox BackUP Server is also missing here.

But it is not very clear to me how to act in case of failure of one of the VM Storage

If we have a backup server, then we can restore on the second VM Storage, but it takes a very long time.

There is a similar scheme on XCP-NG, and there we implemented it by simply doing continuous...

Backup only when guest was/is running

If the guest system was not running since the last backup, a new backup makes little sense.

Current:
Old backups will get deleted and new backups accumulate with no change in between them.

Better:
Add switch to make backups only when guest system was/is running.
