Route OVH IP block to Hetzner to be used by virtual machines?

March 12, 2024, 4:08 pm

Public IPv4 server 1 (OVH bare metal) : 141.94.199.xxx
Public IPv4 server 2 (Hetzner bare metal) : 5.9.105.xxx
IP block I want to use on server 2: 164.132.xxx.xxx/28 (OVH IP Block)

Can someone please assist me on how I can do this via GRE tunnel? Both have Proxmox installed.

Also what would the downsides be to this? (other than extra latency) I know there can be some issues with running a VPN for example due to MTU not being 1500

PCI(e) passthrough of a device that shares vendor:device id

Hello,

I have an HP DL380P G8 with four port onboard NIC and a PCIe four port NIC. They are both seen by Proxmox as "Ethernet controller [0200]: Broadcom Inc. and subsidiaries NetXtreme BCM5719 Gigabit Ethernet PCIe [14e4:1657] (rev 01)"

Is there some way add the PCI(e) card to modprobe to exclude it from Proxmox and pass the entire card through to a VM? When I run "lspci -nnk | grep Ethernet" I get:

I have a separately managed Ceph cluster with an RBD pool pve-vmdata that I use for VM disks. If I create on the Ceph cluster an image, with e.g. rbd create --size 1024 pve-vmdata/myimg, is it possible to add the image to a VM? Can I somehow scan for/detect the new image?

I'm getting ready to upgrade to version 8 starting with my backup server first. I'm installing from the ISO. I get the expected window where I'm selecting the top Install Proxmox option. The software starts to load and a few lines of text show on the screen. But then I get a message on the screen that says "Cannot display this video mode" and nothing more seems to happen. As I understand it there should have been a license screen or something to accept before moving forward with the...

Internet Bandwidth Optimization

Hi,

I have the following dilemma: I have a proxmox node with several VMs with the network through a Bridge (vmbr0) with virtual MACs provided by the internet provider. These VMs have to communicate with each other consuming quite a lot of bandwidth, but the traffic goes out to the internet and back in through the network interface (enp33s0f0). This is consuming public bandwidth and saturating my contracted speed.

I have tried with `ip route` to route the traffic so that it does not leave...

Hello,

When I boot from the iso everything is great.

But after choosing the graphical interface my screen is oversize and I can't manage anything.

Fix always high CPU frequency in proxmox host.

I notice that, even if I set all my CPU governor to powersaving with default intel_pstate drive, still the CPU gets up to maximum frequency as soon as VM started even it is almost idle in VM. CPU report in host show CPU boost up to 4Ghz for all cores. CPU temperature reported at about 50c.

So I replaced the intel_pstate with acpi-cpufreq drive.

since i am using homelab, I will say this is a great improvement, lower CPU voltage, lower temperature. yet not much noticeable performance impact...

HOWTO - Proxmox VE 8-1.2 Wifi w/ SNAT

This is a HOWTO for configuring Wifi for Proxmox VE 8-1.2 w/ SNAT. I've read a bunch of various writeups but none of them are consistent so hopefully this will be a one-stop shop for people to get Wifi w/ SNAT configured. Hopefully this can be added to the Wiki.

Note: This configuration DOES NOT use DHCP for anything. It uses all static addressing.



Prerequisites:

1) Wired ethernet connection - this is required to install wpasupplicant

2) Configure your wifi router to route...

Hi
I would very much appreciate advise how to set for five users an Unpriv LXC UID mapping for ZFS Bind Mount to SMB File server for family
I'm lost with several UID problems both host and guest. There are guides for single user, which worked as start but I need it working for five users.

How should chown be set at PVE Host and Guest LXC for all five unprivileged LXC Samba user to access the two zfs data sets?
Is this the way to go on lxc 100.conf with UID seetings?

Hi @spirit, thank you for the amazing SDN support in Proxmox!

I'm trying to interoperate with an EBGP overlay/EBGP underlay configuration generated by Arista's "validated designs" (AVD) Ansible collection. I have some Proxmox hosts that'll act as L3 leaf nodes in this network, connected directly to an Arista L3 spine switch. The Proxmox hosts need to peer at the EVPN/VTEP layer with some Arista L3 leaf switches that are connected to the same L3 spines.

It's been a bit challenging to...

Sync How swap etc...

Hi, I have a question: is there any possibility to do something like hot swap and, upon detecting a new disk by Proxmox, trigger a synchronization task to copy data there? So far, I've tested with a USB drive, but after removing and reattaching it, Proxmox requires a restart, which, as you can imagine, is not desirable!

So what? I do not care that it has a holder. Kill the holder and wipe the disk as asked! What is the reason for all these workarounds we constantly have to do to administrate these systems?

The disk was previously in a CEPH installation, it is no more, I need it for something else! I can't fathom the logic behind blocking wiping disks because of "holder" This is not Windows... this is linux!

To fix this stuff I once again have to come up with workaround...

Distributing VMs with Proxmox

I'm looking to make a virtual machine available to others that are using Proxmox (through the Proxmox GUI if possible). I'm looking to supply whatever is needed to generate a VM on a Proxmox system with minimal input needed from the user. I expect that will include a disk image (likely qcow2) and some set of file(s) describing the VM that Proxmox (GUI?) can use to generate the VM.

Any direction would be welcome.

We've done something similar for ESXi in the form of an OVA, so something like...
