Description of problem:
Even when Link State is setup to disabled in virt-manager, guest network link is still up when using the e1000e driver, both Fedora and Windows guests tested with same result.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Create new Guest (Fedora and/or Windows) using e1000e NIC, with link state enabled, connecting to NAT network
2. while guest is running, set link state to disabled
3. shutdown guest and start guest
Guest got IP address via DHCP and access to Internet is OK.
Guest NIC link should be down, and no IP address should be assigned.
When the client is up and running, set link down and guest network is down immediately.
But on shutdown / restart, guest network link is up although virt-manager NIC link setting is still down.
Changing to virtio NIC driver, and link state is working correctly.
Tested with Windows and Fedora guest, both give same result.

Thanks for the report. This has been reported before and t's a known qemu issue that has been filed upstream. See the discussion here: https://github.com/virt-manager/virt-manager/issues/66
The upstream qemu bug is here. But it is still not fixed AFAIK: https://bugs.launchpad.net/qemu/+bug/1857226
