After a lot of tries and work with different adapters, cables, switches, I finally changed the IP of vmbr0. Then it worked with all network cards. I do not know why. Also I can ensure, that there was no duplicate IP.

I have a slightly different problem, which seems to concern the network stack in general. I have a standard vmbr0 bridge and an enp6s0 LAN interface. (just standard installation with no change, no VLANs etc.) Since a couple of days (nothing has been changed in the network settings in the...

I downloaded the Header files from http://download.proxmox.com/debian/pve/dists/bookworm/pve-no-subscription/binary-amd64/ http://download.proxmox.com/debian/pve/dists/bookworm/pve-no-subscription/binary-amd64/r8125-dkms_9.013.02-1~bpo12%2B1_all.deb installed them and made modprobe r8125...

I have the same configuration as described here: https://www.reddit.com/r/Proxmox/comments/1hvrwnc/issues_with_realtek_nic_driver_installation_and/ and I cannot install the network card due to missing kernel headers. I could not find kernel header files for 6.8.12-4-pve I also looked at...

Thank you alexander, I had the same problem. Just wanted to add that I needed to add iptables -A OUTPUT -o lo -j ACCEPT also. Then I could telnet localhost 8006 Again and I could login

(I decided to translate it to english as most of the forum here is in english): We have 2 Proxmox machines 6.4 here on which we host VoIP services in LXC containers. Plus a few KVM machines for tunnels etc. The LXC containers are causing us difficulties in terms of load. We are doing load...

Also missing in /etc/pve priv directory authkey.pub datacenter.cfg pve-root-ca.pem pvve-www.key storage.cfg user.cfg vzdump.cron

After struggling with ZFS Raid 1 and high IO load on a plain current Proxmox 5.1 install, I finally tried to install Proxmox on top of Debian 9 and a normal Raid 1. Install worked so far, but web GUI on port 8006 does not show up. Looking in /etc/pve, I see that a number of files and dirs are...

I have setup 2 machines with Intel E1240 v6 CPUs and 32 GB of RAM on latest proxmox51 (Dec 2017). For the time being the machines run independently. After a fresh install and restoring an LXC virtual machine from another Intel machine, I discovered huge performance issues. Machines won't really...

I startet a script in the background which produced 90% CPU load on 1 core. After that, my system became stable for about 3 days, then it crashed again. Today, I installed pm-utils and executed pm-powersave false and disbaled C6 states in grub by adding processor.max_cstate=5...

I also have an Asus PRIME B350M-A Motherboard (like Bogdan), and the System crashes twice a day with core dump on Proxmox 5.1 Initially I had Bios 0611 and it crashed hourly, then I updated to 1001 and it crashed twice daily in Idle and no VMs or CTs running. Then I changed the grapfics card...

Yes, that's what I am always telling my colleagues. Documentation and describing the problem is the most important in a project. I generally write down all tries and errors in the project document. Including the questions I ask myself. That's the only way to handle problems, which are more than...

While describing your problem you get the clue...:) I added net.ipv4.ip_forward=1 to /etc/sysctl.conf and ran echo 1 > /proc/sys/net/ipv4/ip_forward Now I can ping into the container.

I have a similar problem with a Proxmox 4.1 setup on top of a Minimum Debian 8 from the Proxmox host I can ping into the LXC container from within the LXC container I can ping the Proxmox host from within the LXC container I cannot ping the gateway or any external IP from an external IP I...

Hello,I have setup a 2 node cluster. Whenever I try to add another resource, the Proxmox GUI shows the diff but activating always fails with "config validation failed: unknown error (500)".I can add another pvevm, that works, but any other resource fails. I have tried so far "fs", "drbd" and...

You may use the Apache and mod_rewite or proxy balancer for this, dependend on what in detail you want to axchieve. You have to enable a couple of modules for that (with a2enmod)

Just a quick help: A template is the basic virtual machine which is already precreated. As the kernel is shared with the hardware host, you cannot simply install a standard ISO including its own kernel to the VM. A good minimal template I have used is this one...

Hello, I have setup a container with an OpenVPN server. I would like to restrict the connection between some OpenVPN clients, so I have setup iptables in the container. What I have done so far: I have set net.netfilter.nf_conntrack_acct=1 in sysctl modprobed xt_tcpudp and ip_conntrack See...

I installed another client from an openvz Ubuntu 10.04 template. So now I have two running and one failed clients 102 is running (Proxmox Debian 6.0 Standard) 104 has failed (openvz Ubuntu 10.04 amd64) 106 is running (openvz Ubuntu 10.04 amd64) I compared the mtab entries on the machines...
