What commands? The idea is that 'auto-promote' works without any commands.
So I just start the kvm VM on the second node, which tries to open the device.

So I tried to enable allow-two-primaries somehow. Adding it 
to /etc/drbd.d/global_common.conf did not help. Then I tried:

# drbdadm net-options --allow-two-primaries=yes vm-100-disk-1

on each node, and it seems to work now.

So where is the right place to set allow-two-primaries for 
volumes managed by drbdmanage? 

And why is that disabled by default?
