Hi all....

In my fedora9 machine i have a Virtual Machine installed...The ip of virtual machine is 192.168.122.82.

But when i execute ifconfig in my fedora9 machine i get

Code:

virbr0    Link encap:Ethernet  HWaddr 00:FF:5E:31:17:72  
          inet addr:192.168.122.1  Bcast:192.168.122.255  Mask:255.255.255.0
          inet6 addr: fe80::2c7c:1dff:fef8:5fcc/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:57 errors:0 dropped:0 overruns:0 frame:0
          TX packets:50 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:8920 (8.7 KiB)  TX bytes:7813 (7.6 KiB)

vnet0     Link encap:Ethernet  HWaddr 00:FF:5E:31:17:72  
          inet6 addr: fe80::2ff:5eff:fe31:1772/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:57 errors:0 dropped:0 overruns:0 frame:0
          TX packets:625 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:500 
          RX bytes:9718 (9.4 KiB)  TX bytes:33902 (33.1 KiB)

Above what is virbr0 and vnet0 ?

Also ip address in virbr0 is different than Ip address of my virtual machine which is 192.168.122.82 ?

Also there is no ipaddress for vnet0 ?

I am confused...Can anyone please help me...

Thanks in advance...

There can be multiple form of networking exist between host and guest.
like
NAT
Host only networking
Bridged Networking
If you select bridged network then a virtaul network interface created on your guest that is vnet0 that create a bridge interface virbr0. Ip address specified to virbr0.

You can use brctl to view which interfaces are present in bridge interface.
