Just a bit more details about the above installation:
It's a Proxmox 1.4b2 server. We created a KVM VM with network options "Bridge" (vmbr0).
Network settings on Proxmox-Host (default after installation):
Code:
# network interface settings
auto lo
iface lo inet loopback
iface eth0 inet manual
auto vmbr0
iface vmbr0 inet static
address 189.149.217.112
netmask 255.255.255.0
gateway 189.149.217.1
bridge_ports eth0
bridge_stp off
bridge_fd 0
(these are just example-IPs, but the schema is the same on the Proxmox-Host: a static IP and a Gateway on the same network with the adress .1)
So now I have a second static IP, let's name her 178.159.114.146. I would like to build a KVM-VM and assign the IP to it, so the network settings look like this at the moment:
Code:
auto lo
iface lo inet loopback
allow-hotplug eth0
iface eth0 inet static
address 178.159.114.146
netmask 255.255.255.0
network 178.159.114.0
broadcast 178.159.114.255
gateway 178.159.114.1
dns-nameservers 178.177.176.34
dns-search mydns.de
Unfortunatly this doesn't work. After some search on google I used the IP "189.149.217.112" (the IP of vmbr0) as gateway and executed the following commands on the Proxmox Host:
Code:
route add 178.159.114.146 dev vmbr0
echo 1 > /proc/sys/net/ipv4/conf/vmbr0/proxy_arp
Now the proxmox Host can ping the VM and the VM to proxmox, but it's not possible to reach the VM from outside or to ping an internet-host from the VM :-(
Do we also need to activate IPv4/IPv6 Forwarding in /etc/sysctl.conf ?
We like to keep things simple - we have some physical machines running with their static IPs and want to convert them to KVM-Images on the Proxmox-Host. It would be perfect if we don't need to change anything in the network-configuration of the VM, just on the proxmox-host - is this possible? All physical servers will be on different networks, do we have to define several bridge-devices in this case (vmbr0, vmbr1, ...) ?
