External IP to KVM Problem

[Xenus]

Hi,
I have a dedicated server at leaseweb and I can't get networking on a win2008 KVM, I try to follow all the guides at the wiki, read a lot the forums but I have no clue about what I'm doing wrong.
May be I'm missing something.

The installation was made on a fresh Debian Lenny following the guide:
http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Lenny

My host configuration:

/etc/network/interfaces

iface eth0 inet manual
auto vmbr0
iface vmbr0 inet static
        address  XX.211.76.130
        netmask  255.255.255.192
        gateway  XX.211.76.190
        broadcast  XX.211.76.191
        network XX.211.76.128
        dns-nameservers 83.149.80.123
        dns-search localdomain
        bridge_ports eth0
        bridge_stp off
        bridge_fd 0
 
auto vmbr1
iface vmbr1 inet static
        address  XX.211.76.170
        netmask  255.255.255.192
        bridge_ports off
        bridge_stp off
        bridge_fd 0

I ask the datacenter support if they have some kind of limitation (like switches don't support virtual mac address or bridged configuration) and they said that they don't have any kind of limitation, I can use bridged networking and the mac address I want.

Already tried with rtl8139 and vitrio (with the updated drivers) with no luck.

I have configured the windows 2008 guest with the IP details of vmbr1, Am I forgetting something?

Thanks in advance.

Hi,
why you generate two network-bridges for the same network?
If i look right, for you is vmbr0 enough - your host has XX.211.76.130 and your VM should connected to vmbr0 and they can use XX.211.76.131,132....

You need vmbr1 for a seperate network (e.g. 10.10.10.0/24) - and then the host don't need an ip on the network..

Perhaps you have also the wrong nic-driver inside the VM. the windows e1000-driver is broken - so download the original from intel, create a cd-iso and mount this inside the VM. Installation and all should run.

Thanks Udo, It seems I had a misconception about how the connection works.

I updated the drivers and everything it's working great now.

Thanks for the help!

Why don't you post your working config then?
Both host and guest, I am with leaseweb too and are struggling like crazy to get it working.

It was an error on leaseweb network, they had assigned me the wrong subnet, it was belonging to the neighbour switch. Everything working great now
