How to setup KVM in Fedora 18?

I have been trying to setup KVM(Kernel Virtual Machine) on Fedora 18. Now when I reach the final step of setup (I am using virt-manager), it shows that "default" network is not active. I have gone through at least a dozen resources and I am still not able to debug this issue. I am not using any bridges. CEans, help me out!

#-Link-Snipped-# , our Linux Ninja should be able to help you here. He gets high whenever you talk anything Unix and Anti-MS.

Unfortunately,I don't know much detail about KVM.
After I checked this post early morning,I googled & trolled some websites & learnt how to do bridged networking.

If #-Link-Snipped-# provides the steps he implemented in setting up KVM,then it might be possible that I can help.

I am not confident though.
Darn!

Maybe #-Link-Snipped-# can help. I've not laid my hands on Unix machine for a long time now. 😐

OK, #-Link-Snipped-# here is the screen shot.

The problem here is I am not using any bridge. I just want to connect the guest and host using "default" network. Its supposed to be a bug, and the patch is available for ubuntu since 2009! No idea what to do in Fedora!

#-Link-Snipped-# Not all CPU supports hardware virtualisation.
Let's check whether your hardware supports or not.
```
 egrep '(vmx|svm)' --color=always /proc/cpuinfo 
```
Does it gives any o/p ?

#-Link-Snipped-# You are using Unix-like machine 😀

Yeah man, my machine supports virtualization. That's not the problem. Anyways I have solved it. I removed the default network itself! Though it's not the way it should work, but after getting struck at one single point for two days, every solution seems right! And surprisingly, I am able to use my internet connection in guest without the bridge....😀

Okay #-Link-Snipped-# now explain in detail,why we need KVM,Why we need bridging ? Is it only related with Servers ?
I just wanna know it.

BTW Do you love Gnome? or still Unity fan ? 😉

OKay, Kernel Based virtual machine is a simple virtulization software (like vmware), but it differs in the point that it works on linux kernel. As it helps to provide virtualization through kernel, it is able to use hardware more efficiently. Now as we are using fedora and Red hat developed KVM, so its better to use it, saves from licencing issues and all! Bridging basically helps to communicate between guest and host system. The basic idea is you bridge one of you communication port (either ethernet or wlan) to the guest and they too can get benefit of it. I dont think it is only related to servers, hell, I am using it on my laptop....😉 But I guess most of the developers use it for servers only.
Anyways, check this out : <a href="https://www.linux-kvm.org/page/Main_Page" target="_blank" rel="nofollow noopener noreferrer">KVM</a>
I hope you will get most of the answers...😀

Yeah gnome is quite good, but I think I am gonna need some more time to get over unity. Our relationship ended unexpectedly...😉
