[PVE-User] lxc-pve 3.1.0-3 causes weird behavior with ansible

[Christian Almkvist]

I´ve been running anisble on the pve host with the lxc connection plugin 
against local lxc-containers.
After the latest lxc-pve upgrade to 3.1.0-3 I´ve noticed 2 issues:
1. Ansible playbook runs never finishes (commad/output freezes at the end 
of the play).
2. Every "vars_prompt" seems to trigger twice for some reason.
Apart from this everything seems to work as intended,
This issue presists across diffrent Ansible versions, but completly goes 
away if downgrading to lxc-pve 3.1.0-2.


Not sure if this is a pure Ansible issue or maby a problem in the lxc upstream?
can´t seem to find any reports of this anywhere.
Has anyone else encountered this behavior lately?


Doing a strace on the ansible playbook-command shows an endless spam of the 
following line:
select(0, NULL, NULL, NULL, {tv_sec=0, tv_usec=1000}) = 0 (Timeout)
