[TriLUG] KVM on a laptop

Note that I've removed the br0 in an attempt to appease Network Manager.

With it added in, it looks like this:

After undocking, it looks like this:

I then dropped br0:

Docked (at this point, my networking stops working; iptables -L takes
45 seconds to complete) but the important part (IMHO) is that route -n
looks like this:

[jtate at laputa prj1]$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         10.2.2.1        0.0.0.0         UG    0      0        0 eth0
10.2.2.0        0.0.0.0         255.255.255.0   U     0      0        0 wlan0
10.2.2.0        0.0.0.0         255.255.255.0   U     0      0        0 eth0
192.168.122.0   0.0.0.0         255.255.255.0   U     0      0        0 virbr0

So I ifdown eth0, ifup br0 and my routing table is back to the
original bridged setting, but Network Manager thinks I'm only
connected to WIFI and networking is SLOW.  So I drop Wifi, networking
is fast again from the console, but any Network Manager aware
applications think I'm offline:

I have to reenable wifi just to pastebin.
