https://issues.apache.org/jira/browse/CLOUDSTACK-1907
Hope to raise awareness of this issue before the 4.1 release. I'm trying git 4.1 today. XenServer 6.1 works fine, but XCP 1.6 stops System VM from starting. It turns out to be a guest os type mismatch problem. The script xcp1.6-debianfix.sh works by cloning the guest os template to have the name "experimental," but the better way to fix this issue is to add one line in com.cloud.hypervisor.xen.resource.CitrixHelper,java: _xcp100GuestOsMap.put("Debian GNU/Linux 6(64-bit)", "Debian Squeeze 6.0 (64-bit)"); because in XCP 1.6, Debian Squeeze 6.0 (64-bit) is no longer "experimental." CloudStack needs to find a matching guest os template to start the system vms.
