Description Vladimir Benes 2015-01-16 12:40:17 UTC
Description of problem:
I've set ipv6.method to shared to connection operating over existing ethernet device and I cannot up it anymore.

Error: Connection activation failed: Active connection removed before it was initialized

Version-Release number of selected component (if applicable):
NetworkManager-1.0.0-8.git20150107.1ea95cd3.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.nmcli connection add type ethernet con-name ethie ifname eth1
2.nmcli connection edit id ethie
3.set ipv6.method shared
4.save
5.quit
6.nmcli connection up id ethie 

Actual results:
Error: Connection activation failed: Active connection removed before it was initialized

Comment 1 Dan Winship 2015-01-16 13:40:14 UTC
"shared" is not yet supported for IPv6, so this isn't entirely a bug. We should probably return an error immediately when you try to activate it though, rather than allowing activation to start and then failing afterward.
