unable to assign host interface name

In previous release 2.0.6 for Fedora 9, I was able to assign to "host Interface" any of the user defined bridge interface under say br0, by typing for example tap77 for all bridge intf, now this is not allowed on user UI. Even if I manually change this in my xml definition file still does not work.

I was not able to assing tap77 from br0 as a Host Interface.

My fc9 box is configured with br0 at, the winxp guest is assingned, using Virtualbox 2.1.0 code, for bridged network, winxp is not able to ping fc9 host, packet are not routed properly to the host.

In Virtualbox 2.0.6 version, user is able to enter by hand, it desired tap interface, this is no longer an option in Virtualbox 2.1.0 release.

In 2.1.0 the default host interface choosen happens to be br0, which happens to be my br0 interface not my tap interfaces.

  • Status changed from new to closed
  • Resolution set to fixed

This should work, IIRC assigning to a TAP device was fixed with 2.1.2 or 2.1.4. Please try the latest release 2.2.2 and reopen if this still doesn't work for you.
