mac address

Hello! I'm quite aware that there may be a few threads that detail similar issues like the ones I am facing, however this seems to be slightly special, especially with OVH's strange networking. The following setup is given: Proxmox VE 8 Host on latest Version with all Updates installed. Said...

I'd like to Pre-generate the Mac Address for a tool I'm building. I'm currently using one for VMware (and VMware only allows specific MAC addresses) and wondering if Proxmox has something similar? Is there a Proxmox SPECIFIC Mac address generator? (i'm guessing there is a function in the...

Hi I recently noticed a problem, I use a Mellanox VF (Connectx-5 EN) and it seems like it changes MAC-adress for each boot. That's a problem since I use SLAAC to add IPv6 adresses. Here is a screenshot from the manual. I guess that I can't be the only one with this issue, is there some good way...

This isn't really a problem (or at least I hope so), I just want to understand proxmox better, but I didn't know where to ask this, and I didn't find any answers on the forum. I was just messing with the router settings when I noticed, that whenever I turn on my proxmox machine, I have 2 more...

Hey, Ich habe jetzt in den letzten tage so viele Beiträge gelesen und getestet aber noch bin ich nicht am ziel wie erwartet. So kommen wir mal zum Problem: Ich habe eine Haupt IP nenne wir die mal <1>.244 und habe mir jetzt eine einzelne Zusatz IP gekauft die wir <2>.253 nennen. Das Problem ist...

I was messing with one of the nodes on my proxmox cluster and experimenting with putting the management interface/GUI on it's own VLAN, and in the process managed to completely kill the network connectivity on the node even after undoing all my changes. I'll try to explain in a series of steps...

Hello everyone I have a custom firewall rule for a few VMs that I can't enter in the GUI. The most elegant way would be to load it directly at startup by "post-up" in the /etc/network/interfaces file. The rule looks like this: ip6tables --insert tap181i0-IN -m mac ! --mac-source...

Hello, I have been using PVE for several months and recently I had to change my motherboard, after replacing the motherboard of my server I have a defect when starting the promox distribution: [FAILED] Failed to start LSB: Personal Firewall :mad: In front of my server I use a netgate...

Hi everyone. I need to install a software license server vm which requires a MAC address to stay consistent. How can I use the same MAC address if I decide to reinstall this VM? Thanks! Newbie here!

Guten Abend, kurze Frage: Ich würde gerne die statische IP Adresse meines Proxmox Servers über den Router vergeben (DHCP -> statische Adresse über MAC-Adresse). Bisher habe ich die Adresse direkt auf dem Proxmox eingetragen. Ich habe zwar gefunden, wo ich die Adresse des Proxmox ändern kann -...

Hi! Please help.

Hi Proxmoxers, Running a few VMs and CTs on Proxmox 6.2-4 on a server with multiple NICs. NIC ports are assigned to Linux Bridges and then connected individually to a particular VM or CT via the hardware GUI. I have noticed that in pve (in shell when I run ifconfig), the MAC address assigned...

My network has some issues. When the network traffic increases, the network connections tend to be very slow even though it's an 10GB network. I'm not sure whether it's proxmox-related or not. Example: VMx = virtual machine x VHx = proxmox virtual host x VM1 = 192.168.0.51 (E2:A9:CC:75:79:AF)...

Greetings fellow Proxmox users and moderators. First I want to thank the Proxmox team and developers for creating an amazing product. I have been a Proxmox user for only about 2 years but a Linux admin for about 15 years. Regrettably I have not created a forum account until now, however I...

Stumbled across something interesting last week that took me a while to understand. I have a number of VMs that use PXE-boot to install Centos7. I serve custom kickstart files from a local tftp server. Part of the kickstart file has an %include section that points to a local http server by a...

Hello, I have Proxmox 6 Server with LXC Containers. If I added some network adapter to one container everything works fine, mac address is on default settings (auto). But no mac address will generate. In syslog I have this error message: systemd-udevd[22359]: link_config: autonegotiation is...

I had update proxmox to latest version just now. It occurs problem. When I reboot LXC, LXC's mac address will change automatic. It makes me impossible to bind static address.

Anyone successfully used the Ansible module of proxmox_kvm to get a MAC address of a VM for a PXE install? Here is the task code: - name: Get Facts proxmox_kvm: api_user: "root@pam" api_password: test api_host: test node: test name: test validate_certs: no...

I have a server from hetzner, and install proxmox on it. My configuration is simple, and it's my "/etc/network/interfaces" file: auto lo iface lo inet loopback iface enp6s0 inet manual auto vmbr0 iface vmbr0 inet static address XX.YY.ZZ.TT netmask 255.255.0.0 gateway...
