Hi!
Been trying to get my Proxmox setup with a OPNsense as firewall and router. Where vms can connect to and be NAT:et out.
Cant seem to get it to work, have tried so many diffrent approaches but still no luck.
I have currently configured my Proxmox:
Bash:
auto lo
iface lo inet loopback
iface ens18 inet manual

Hi
I'm testing Ceph on 4 Proxmox Servers. Each Server have 4x Intel SSDPE2KE032T8 NVMe Disks. All 16 Disks have 3 Partitions witch represent 1 OSD (48 OSDs in Total).
If I'm testing the Diskspeed with DiskSpd in one Windows VM. I'm getting only 40MB/s. If I'm testing on 2 Windows VM at the same time on the same Host, I'm getting 40MB/s on each VM. Is there any limitations per VM? Like a fair use policy? And can this be disabled? FYI: The Speed with a Linux VM are the same or slightly better...

Hi there,
i've bought a PCIe-NIC with RTL8126 chip (1,2.5,5 Gbit) and having problems to set it up correctly.
The chip actual isn't supported by the actual proxmox kernel (6.8.x.x) and on the realtek driver site (
https://www.realtek.com/Download/List?cate_id=584) is only one entry for this card: 5G Ethernet LINUX driver
r8126 for kernel up to
6.4
I'm no linux pro, but what i did: Booted several PVE-Kernels (6.8, 6.5., 6.2) and installed the driver package (unpack the...

Hallo zusammen,
aktuell nutze ich den Free (Legacy 2018) Plan von ClouDNS, damit schaffe ich es aber nicht eine ACME DNS Challenge durchzuführen.
Angeblich sind die Credentials immer falsch.
Ich habe nun mit dem Support geschrieben und obwohl ich einen API user anlegen kann, darf ich diesen scheinbar nicht nutzen.
Also muss ich mir wohl einen anderen DNS Hoster suchen.
Bei diesem soll DDNS möglich sein und eben eine ACME DNS Challenge.
Hat jemand Empfehlungen oder eine Idee wie man die...

Today I ran the basic apt update && apt upgrade. I was greeted with a question from grub update about where I would like to install the grub bootloader. My system boots from dell raid controller using UEFI and has not asked such questions before when updating. I selected the /dev/sda as per that is the disk where the pbs itself is installed on. After selecting that, the installer created warning that the boot partition was under 1mb??
I have not yet tried to reboot the system but should I...

Moin zusammen,
ich bin recht neu im Thema Proxmox.
Ich wollte ursprünglich den Festplattenspeicher einer VM erhöhen und habe dazu gegoogelt wie ich das mache. Dummerweise hatte ich die falsche VM ausgewählt und habe nun dort den Speicher vergrößert, was ich eigentlich gar nicht wollte.
Ich kann in der GUI im Fenster "Resize Disk" aber keine negativen Werte angeben. Die VM ist seit der falschen Änderung noch nicht neu gestartet worden. Kann ich das noch irgendwie rückgängig machen...

What?
Are you wanting to use PBS to backup your servers, but want to use TrueNAS as the storage handler?
I've been using this setup for the last few weeks and it has worked perfectly.
With the latest update of TrueNAS Community Edition, 25.04, you can run Linux Containers (LXC) natively on the system.
Why?
This will allow you to have the ZFS back end of TrueNAS handle snapshots, replication, etc. for a robust storage layer. TrueNAS is a...

Hi
Our PBS today ran out of storage, it's sitting at 100% and "zpool status" outputs "no pools available"
We've been getting (os error 28)
Full error log:
"ERROR: Backup of VM XYZ failed - VM XYZ qmp command 'backup' failed - backup connect failed: command error: No space left on device (os error 28)"
I was wondering if someone could eventually help me expand the PBS volume size. Deleting old backups is last option I'd want to take.
Thanks a lot in forward!
P.s. I'm somewhat of a...

Hello,
I have read about Proxmox Backup server but it is not clear to me some matters.
Lets suppose the following scenario :
- we have a Proxmox server backup should installed on a bare metal with at least 10GB RAM
and 32GB HD .
- we have a proxmox cluster 8.3 containing 4 nodes configured with 2TB of zfs storage on each one,
On each node there are running at least 5 VMs
- we have 2 NAS of 8TB to use as storage for backups
Can I full backup all VMs on all nodes on NAS ?
Can...

Hallo,
ok, nun ist bei mir ein Senior dran.
Ein ESXI 5.5 mit 5 VMs unter Windows 2019 und sogar eine noch unter Win 2012 R2.
Leider bekomme ich bei zwei Maschinen eine komische Fehlermeldung.
can't open '/run/pve/import/esxi/
ESXI5/mnt/ha-datacenter/Internal/Name-Name/Name-Name.vmx' - No such file or directory (500)
Die Vm in ESXI startet problemlos und alle Disks sind auch an der richtigen Stelle.
Ich habe leider überhaupt keine Idee, woran dies liegen könnte - noch leider wo ich...

Hello everyone,
I’m experiencing a network issue on my Proxmox server and could use some help troubleshooting. The server has been running smoothly for a while, but recently it started losing network connectivity. It works fine for a few minutes after rebooting the router (Unifi router), but then it disconnects again. I've attached a screenshot of the console showing the repeated error messages.
Error Message:

When I had Proxmox 7.x, I also used Wireguard in LXC. I always set it
accordingly. In the summer of 2023, I switched to Proxmox 8.x and forgot to do this setting, and Wireguard still works in LXC. Is it necessary to do this setting only for OpenVPN, or also for Wireguard? Someone answered on
redit that this step must not be taken.

Hello,
We are currently testing Proxmox and have two physical sites connected via the same network but with different gateways.
We already have a VMware cluster successfully running between these two sites.
For our Proxmox setup, we initially created:
- Site A: 2 Proxmox nodes
- Site B: 3 Proxmox nodes
At first, we set up two separate clusters—one for the nodes in Site A and another for the nodes in Site B—without issues.
Then, we decided to reinstall Proxmox on...

New to Proxmox and working on cluster design. I've seen a few references that corosync should be on its own network/NICs, and have a backup link set.
We have an existing Virtuozzo cluster. We were planning to re-use those servers, but they have only two 10 Gbit NICs (storage network and front/public network). The plan would be to replace those over time. In the meantime though, we were hoping to install Proxmox remotely on these older servers, and adding a NIC would cost a bit of money...

I am running an opensense VM in proxmox and while VM-VM throughput on the same VLAN can do ~32Gbps, routing across VLANs incur a 94% penalty dropping it to 2Gbps.
I understand this is a limitation of emulating a L3 switch through software in which these devices typically have tailor-made ASICs for routing packets. I have tried a) setting multiqueue to 4 b) hardware offloading is disabled by default c) cpu type is host and aes flag is added anyways just to be sure.
Currently I am assessing...

Hi.
We have noticed another issue with our migration from VMWare ESXi, to Proxmox.
One of our VMs has a HAProxy configured in TCP mode which passes connections to SQL server on other machine. Nothing fancy, there is almost no logic behind it, just take a TCP connection and pass it over to one of the SQL servers statically set in config.
That machine handles likes 400-500 sessions per second, which is not much, but eats up 70-80% of CPU (8 cores) when doing so. We started same machine on...
