mac address

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...

Ì'm having some issues with macspoofing on Proxmox as my CARP Master/Backup VIP's are flapping in state between the servers and stay that way they are set. I have checked: Disable hardware checksum offload Disable hardware TCP segmentation offload Disable hardware large receive offload...

When a Virtual machine is cloned, Proxmox deals with the MAC address by assigning a new one so there is no conflict. However, when cloning a LXC (by backup and restore to a new container), this does not happen. It would be nice to have feature that provider either: 1. An option to...

Hi. I 've got some troubles with VM and CT haven't access to network. After figure out, i found the trouble. It was a MAC prefix trouble. In fact I typing '69' for making sure to do not have some hardware conflict. But it doesn't support i think. I replace it by a simple '00' and all works...

Hey guys! So here is our config A dedicated server at OVH. Ipv4: for the proxmox host (also has 1 ipv6) We also have /64 of ipv6. So OVH blocks NDP, and does not give any Mac address for ipv6. If we give an IPv4 for a container, we can use ipv6, since it will the ipv4 MAC address. We want...
