Running ASA 8.02K8 inside of the gns3 on win 7 professsional 32bit caused, that console is hanging and did not answer, stay clear.

The problem is that in the general settings in the qemu, in all the references to the host in which the qemu is running it says “localhost” and windows 7 always makes reference to localhost to the ipv6 address. To solve the issue change the word localhost for 127.0.0.1 that is the ipv4 address of localhost.
