PIX active/active failover configuration involves using groups and assigning firewall contexts to groups. On the both firewalls only one group is active at the time. See below the .net file used to run both firewalls in Dynamips/Pemu

PIX/ASA contexts – virtual firewalls emulation on PC

The below example is based on Internetwork Expert CCIE workbook . It shows how to emulate firewall virtualization using Dynamips and QEMU on windows PC. Dynamips is a Cisco router emulator which emulates 1700, 2600, 3600, 3700, and 7200 hardware platforms, and runs standard IOS images. QEMU is processor emulator (using a portable dynamic translator), emulates a full system (usually a PC). Routers R1 of CustomerA and Router R2 of CustomerB each connect to one PIX firewall through interfaces InsideA and InsideB and are allocated to two virtual contexts. Customers have their own virtual interfaces in DMZ and OUTSIDE
