I struggled quite a lot of get ASA 8.4 working on GNS3. I had 8.0(2) working and was helping to test the configurations and VPNs but now wanted to get 8.4 running such that I can prepare myself for new NAT statements and migration from 8.0(2) to 8.4(2).
Here are the steps to get it working.
1. Download the ASA 8.4 files for GNS3 from the following address
2. Configure GNS3 as following. ( I am using Ver 0.8.2 Beta 2, Also Tested 8.3 with Windows 7 64 bit which worked without any issues). Type the code below into relevant fields
Qemu Options: -vnc none -vga none -m 1024 -icount auto -hdachs 980,16,32
Kernel cmd line: -append ide_generic.probe_mask=0x01 ide_core.chs=0.0:980,16,32 auto nousb console=ttyS0,9600 bigphysarea=65536
3. Once the firewall is up and running use following activation keys
activation-key 0x4a3ec071 0x0d86fbf6 0x7cb1bc48 0x8b48b8b0 0xf317c0b5
activation-key 0xb23bcf4a 0x1c713b4f 0x7d53bcbc 0xc4f8d09c 0x0e24c6b6
It will take a while (10-15 min) to accept the second activation key and will take the same time at first reboot.
That's all done and we have a working firewall to play with.
Now if you want to run two ASAs, you will have to change the Qemu options on the second firewall as below
Qemu Options: -vnc :2 none -vga none -m 1024 -icount auto -hdachs 980,16,32

I have posted a LAB Guide for migrating NAT from 8.2 to 8.3/8.4 Version, which is still work in progress but has a lot of stuff already added into it
