Any workarounds to overcome this issue? I am basically stuck with this...
I cannot access via ssh as well, tried with private and public network to launch instance...
1. With private network:
- dhcp can assign an IP address successfully, but the subnet doesn't exist on host so I'm unable to access the instance.

> To follow what Vincent said - maybe you can -download cirros-0.3.4-x86_64-disk.img [3] and see.
I think 0.3.4 also has the bug, but you could try with one from:
http://download.cirros-cloud.net/daily/20160722/
The password may have changed to letsplay2, c.f.:
