Hello, I am attempting to create a bridge to WiFi on Fedora 19, but it is
failing.
In Virtual Machine Manager's View > Connection Details > Network Interfaces
> Add Interface, I was able to create a bridge to my Lenovo ThinkPad T510
laptop's ethernet port, and it works with my VM. However, when I try the
same procedure to create a bridge to my WiFi card, it fails.
These are the options I am setting:
===
Interface type: Bridge
Start mode: onboot
Activate now: checked
Interface to bridge: wlp3s0 (em1, virbr0-nic, and lo are also available
options; em1 is my ethernet port)
===
This is the error I get:
===
Error creating interface: 'Could not create interface: internal error
failed to create (start) interface br1: failed to execute external program
- Running 'ifup br1' failed with exit code 1:
Determining IP information for br1... failed; no link present. Check cable?
'
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/asyncjob.py", line 100, in
cb_wrapper
callback(asyncjob, *args, **kwargs)
File "/usr/share/virt-manager/virtManager/createinterface.py", line 1134,
in do_install
self.interface.install(meter, create=activate)
File "/usr/share/virt-manager/virtinst/Interface.py", line 258, in install
raise RuntimeError(errmsg)
RuntimeError: Could not create interface: internal error failed to create
(start) interface br1: failed to execute external program - Running 'ifup
br1' failed with exit code 1:

===
I notice that if I have no ethernet cable plugged in so that WiFi is my
only connection, and I have a ping running while I do this, the ping starts
returning the below message shortly after I click Finish. I do not have
network access again until I use NetworkManager Applet to reconnect to my
wireless router.
ping: sendmsg: Network is unreachable
I also tried a bit of fixing on my own. I edited
/usr/share/virt-manager/virtinst/Interface.py and put a time.sleep(30) just
before the iface.create(0) that fails, and I reconnected to the router
during that 30 second pause (and ping started working again), but the
interface adder just failed with "Failed to create virtual interface"
instead. I have since restored Interface.py to the original version.
Does anyone have any idea how I can get this to work? Or, is there a
different procedure I should follow to bridge my VM to WiFi? Any help is
appreciated.
Thank you,
