Proxmox 3.3-5 - Network error - Mode bridged VM

ruben_2014 · Feb 24, 2015

Good afternoon,

I am trying to configure a network with Centos 6.4 for KVM Proxmox but still no pings, if I can lend a hand, or see what adjustments should be applied:

Configuring the Host:

/ etc / network / interfaces

Code:

[COLOR=#333333]auto lo[/COLOR]
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

iface eth2 inet manual

iface eth3 inet manual

auto vmbr1
iface vmbr1 inet manual
        bridge_ports dummy0
        bridge_stp off
        bridge_fd 0
        post-up /etc/pve/kvm-networking.sh

auto vmbr0
iface vmbr0 inet static
        address  94.23.x.x
        netmask  255.255.255.0
        gateway  94.23.x.254
        broadcast  94.23.x.255
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
        network 94.23.x.0
        post-up echo 1 > /proc/sys/net/ipv4/conf/vmbr0/proxy_arp [COLOR=#333333]        post-up iptables-restore < /etc/iptables.up.rules[/COLOR]
