Hi Martinx,
We have another solution for this issue.
Changing MTU of each instances is very feeling heavy for me. If you are OK
for lowering the performance,
you can avoid this issue by disabling 'pmtud' of OVS.
% sudo ovs-vsctl set interface gre-2 type=gre
options:remote_ip= options:pmtud=f
Just a ERRATA... I tried it from within 2 instances, ubu-1 and cir-1 (but
cir-1 is another Ubuntu, not cirros)...
Tks!

Good to know!
"ip link set mtu 1454 dev eth0" from within the Instance fixed my problem!
Thank you!
Best,

Martin,
There was a discussion happened on this topic already.
Either set the MTU value in the instance to 1454 (cirros$ sudo ip link set
mtu 1454 dev eth0)
or
Increase the mtu to 1546 on the interfaces on the network node and the
computes nodes that have the GRE tunnel endpoint IPs.
