Currently if you're running CirrAS in a VMware or Xen or KVM environment you must tell somehow JBoss AS instances where the loadbalancer (front-end appliance) is located.
To run CirrAS on you must edit /etc/sysconfig/jboss-as6 file in all back-end appliances.
If your back-end appliance is running on node with 172.16.10.134 IP and front-end appliance has a 172.16.10.133 IP address, edit /etc/sysconfig/jboss-as6 file like this:
Note: Remeber to add valid port to JBOSS_PROXY_LIST!
Please make sure, that after you add appliances to ESX/ESXi inventory you have selected valid Network label. CirrAS default is NAT on VMware personal (Fusion, Workstation) and VM Network on VMware enterprise (ESX/ESXi). You can change this in VMware settings after importing to invoentory an appliance.
