unique IP for KVM

[AGo]

Hi everybody,

this is a pretty beginner question, but I´m somewhat lost.

I have Proxmox 1.6 runngin, a single NIC on the host with 5 IPs assigned to it,
84.x.x.170-84.x.x.174.

I have some openVZ containers which I can easily assign IPs to.
However now I need a KVM Client running Ubuntu linux, and want to assign
the public IP 84.x.x.174 to it. But all I get when I enter the IP is the proxmox
control panel. Everything is running except no network connection. Any idea what
I am doing wrong?

The VM has vmbr174 connected as realtek ethernet card.

Thanks,

André

This is what my interfaces lookes like on the host

# network interface settings
auto lo
iface lo inet loopback

iface eth0 inet manual

auto vmbr0
iface vmbr0 inet static
	address  84.x.x.170
	netmask  255.255.255.0
	gateway  84.x.x.1
	bridge_ports eth0
	bridge_stp off
	bridge_fd 0

auto vmbr174
iface vmbr174 inet static
	address  84.x.x.174
	netmask  255.255.255.0
	bridge_ports none
	bridge_stp off
	bridge_fd 0

little update:

I thought it would be sufficient to declare an alias eth0:174 like this

ifconfig eth0:174 84.x.x.174 up

i
on the host and then add that as a bridged device via the proxmox webgui, but when assigning the device to the vmbr174 i get "Error: unable to bridge device 'eth0:174' " Any clues?

I think you just hook the guest into vmbr0 (on the web interface) and configure the network settings in the guest.

Thanks for your reply, you´re totally right.
No need for any config on the host. After all it turned out to be a missconfiguration on the client side, a typo in resolv.conf...
