CS 4.1.1 XenServer sysvm iso

[John Skinner]

Hey List, 

We are having an issue where system vms (routers, ssvm, console proxy) are 
failing to boot. This is with CS 4.1.1, and XenServer 6.1. The VM gets created, 
and the sysvm iso gets mounted to the VM, however, the VM fails to boot from 
the iso, it just sits there. You can unmount the iso, and mount for example a 
CentOS ISO and it boots just fine. Has anyone else ran into this, or have any 
ideas? Thanks!
