Network Setup proxy arp

[blocker]

Hello,

i have a question regarding the network setup of the proxmox VE using it with proxy arp

so here is our network setup (already talked to the network admin and he refuses to make changes... so i really need to get proxmox VE running on that network setup)

the network uses static routing, and does not allow the use of multiple MAC's on one switch port, so i need somehow to do mac spoofing

if i manually setup the network of the server like this:

• a host
  living under 192.168.10.10 with a netmask of 255.255.255.0
• a KVM guest
  designated to live under 192.168.10.20
  

eth0 stanzas come here....

auto tap0
iface tap0 inet manual
tunctl_user root
uml_proxy_arp 192.168.10.20
uml_proxy_ether eth0
up ip link set tap0 up
post-up sysctl -w net.ipv4.ip_forward=1
post-up sysctl -w net.ipv4.conf.tap0.proxy_arp=1
pre-down sysctl -w net.ipv4.ip_forward=0
down ip link set tap0 down

and then start the guest like this:
kvm \
[...] \
-net nic \
-net tap,ifname=tap0,script=no \
[...]

it runs out of the box with this setup on my network config


How can i make this setup work with the proxmox VE


Thanks for your help in advance!

p/s in the examples above i used private IP addresses, but in my real setup we have to use real IP addresses

Hey,

i have the same Problem here. Who can i edit the Proxmox KVM Startscript? Or in which format can i write this in the Qemu-Server conf?

Thank you!

Sorry, but modifying the KVM start script is not supported. What exactly do you want do to?

I setup my network with this Howto:

http://tjworld.net/wiki/Linux/KvmQemuEasyRoutedNetwork

On the last step

-net nic,model=rtl8139,macaddr=56:44:45:30:31:32,vlan=0 -net tap,script=no,ifname=tap0,vlan=0

How can i start the KVM with this options?
