Description Bill Nottingham 2009-07-01 17:31:27 UTC 
Description of problem:

i.e., one where the network cable isn't there.  If it can do this, it's extremely non-obvious how to set it up. Setting things up such that you get:

"Warning: vlan 1 is not connected to host network"

still leaves you with a device that always reports a link.

Version-Release number of selected component (if applicable):

qemu-system-x86-0.10.5-3.fc11.x86_64
Comment 1 Mark McLoughlin 2009-07-01 21:22:34 UTC 
Does the "set_link e1000.0 down" monitor command do the trick? Only works with e1000 and virtio at the moment
Comment 2 Bill Nottingham 2009-07-02 17:08:08 UTC 
It seems too. mii-tool lies, but it's known to be sort of broken.
Comment 3 Mark McLoughlin 2009-07-03 12:51:12 UTC 
Okay, thanks
