  1. I am using the lastest Proxmox VE 2.1.
  2. My server has two NICS with a uplink only connected into eth0.
  3. My Server is a co-located server utilizing public IPv4 IPs.
  4. It is not behind a firewall or any system which monitors traffic.

Via IPKVM I did a fresh install of Proxmox, I put in the correct IP, Mask, Gateway, and DNS information. The install went perfectly fine with no errors.

Upon completion and rebooting the system:

  1. I am unable to reach the web GUI via the browser, it just times out.
  2. I am unable to ping the server.
  3. I am unable to ping outside to the Internet from within the server. Tried pinging out to and
  4. I tried rebooting the server and restarting the network service.

IFCONFIG shows my IP information under vmbro0 which also has the same MAC address as the eth0 device.

eth0 only displays a IPv6 Scope:Link address, which I did not setup myself.

This is my first time installing proxmox, but after searching for a few hours it doesn't seem like anyone else is having the same issue as me from a fresh install with just the defaults. So far the only thing I did was install it.

Also, I know the network cable is good and the IP is good because I was running a Xen XCP server with the same network settings prior to wiping it to install proxmox.

Some additional information:

  1. for pveversion -v (Installed proxmox-ve_2.1-f9b0f63a-26.iso)

    • pve-manager: 2.1-1 (pve-manager/2.1/f9b0f63a)
    • running kernel: 2.6.32-11-pve
    • proxmox-ve-2.6.32: 2.0-66
  2. netstat -nr (note: .136 is my network, and .137 is my gateway)

    • Destination - Gateway - Genmask
    • - -
    • - -
  3. /etc/network/interfaces

auto lo

iface lo inet loopback
auto vmbr0

iface vmbr0 inet static
                bridge_ports eth0
                bridge_stp off
                bridge_fd 0

Same issue here. I cannot get version 2.1 to install without getting Starting web server: apache2Syntax error on line 13 of /etc/apache2/sites-enabled/pve-redirect.conf: SSLCertificateFile: file '/etc/pve/local/pve-ssl.pem' does not exist or is empty Action 'start' failed. The Apache error log may have more information. failed! I've tried over 20 times! – capdragon Sep 23 '12 at 4:49
What does ifconfig say? Perhaps your network card is unsupported by the kernel? – 200_success Jan 24 '15 at 6:41

Check out this resource :

Host not found cant ping or use aptitude update in proxmox ve?

Thanks for the reply, but that link doesn't relate to my issue. The issue in that link is a DNS issue with 2 NICs bonded. The issue I am having is absolutely no connectivity while utilizing only 1 NIC. – Damainman Jul 28 '12 at 5:56
