Hello

I have laptop with Centos 6.5, i'm using wireless to get internet connection.
I need build lab with XenServer (inside xen few linux vms) and with few separate windows vms.

I want have XenServer and other windows vms in same network (192.168.1.x), as my host (Centos 6.5) or Internal network eg 10.x.x.x (with intenet connection).

In VirtualBox i had no such problems (bridging wlan0), but i need create my lab based on KVM.
And in KVM i have problem with that.
I read that there are problems with bridging wireless interfaces.

Can you please help me, how to solve this ?.

Maybe an issue.

There is no real reason that you can't use nat as long as you understand that the vm has a virtual router.

Yes, i realize that vms have virtual router.
But from what i know, in NAT setup vms getting same ip, there are isolated from each other, but have internet connection.
Am i wrong ?

So i read about bridge host interface with virtualization software interface, to get connection between vms.
But after no succeed with bridging wireless interface, i lookup in search engine, and i found that there is problem with that under linux.
Is there some special things to do, to get wlan brigde working ?

Please, i stared playing kvm just a wile ago. I need some extra explanations.

Eg. I tried in NIC setting set
source Device as host device wlan0: macvtab
device model - default
source mode: brigde

But after loging to windows xp, and realising new ip, i couldn't get ip from 192.168.1.x as my host network is in.
I'm getting 169.254.254.55/8

One can set up vm's for internal only but that locks out host.

If you want to use any lan/wan then you'd need to go with nat or bridged. You pointed out a new way for KVM to connect bridged that I've never used yet. The MacVtap is almost a virtual device with it's own config. I think your example is not fully describing the macvtap as macvtap0 maybe?
