I'm normally using this type of setup:

Load mac80211_hwsim and start two copies of wpa_supplicant (wlan0 and
wlan1 netdevs) with the following configuration file:

ctrl_interface=DIR=/var/run/wpa_supplicant

Run "wpa_cli -i wlan0" and "wpa_cli -i wlan1" in separate terminals and
run P2P operations in them.

In other words, nothing that special here..

Which kernel/mac80211 version are you using? Anything remotely recent
should have that working fine.

wpa_cli output looks like this in a simple group formation test:
