My laptop is running Debian 7. I am running KVM/Virtual Machine Manager for vms and have installed Arch as a guest but I can't get networking working.
I also have KVM running on Debian on my home server. On the server I set up a bridge but I am using ethernet. On my laptop I am using wifi and don't want to set up the bridge because that involved stopping Network Manager and I prefer to have that on for ease of use with wifi connections.
I'm doing almost the same thing as you but I'm using wicd instead of network manager on my laptop. I use virt-manager to look after my VMs and bridged virtual network. It works flawlessly.

maybe a stupid question, but are you bridging your wifi ?
I tried to set up it up with br0 bridged to my wlan0 and I get an error that wlan0 can't be added to br0. I also tried setting up a virtual network through Virtual Machine Manager's gui and get :
Error creating virtual network: internal error Network is already in use by interface wlan0

Perfectly valid question, the answer is yes.

Did you first remove all traces of your manually created bridge? (setup in /etc/network/interfaces?). If so there should already be a "default" network that will work through any physical device. Launch virt-manager, from the "Edit" menu select "Connection Details" and then select the "Virtual Networks" tab. There should be a network there called "default" with "Forwarding:" set to "NAT".

Can you confirm this?

Sorry, just got back to this. So, default network forward to NAT does exist. I have deleted all traces of bridge interfaces. still can't connect to network. I have not been able to install a desktop on Arch (i'm assuming because I can't get online). When I run the VM, I can't load on websites on my laptop (i.e. host system). So it does seem my network is getting taken over when KVM is running. Is it possible that there is something I need to do in the Arch guest to start the network service or something like that?
