5.5. xe compatibility mode

For backward compatibility with scripts written under earlier versions of XenServer there is a compatibility mode invoked by using the compat argument, setting it to true.

The compatibility mode is intended as a migration aid only, and there some known limitations:

error messages might differ from that returned by earlier versions for VM lifecycle commands
setting the XenServer Host password with the host-password-set command does not work in compatability mode.
the host-param-list returns unknown for some parameter values.
the host-pif-list command does not return an IP address or subnet mask, since XenServer 4.0 hosts only bind an IP address to a single management interface.
the host-shutdown and host-reboot commands require that any VMs running be halted first, or a HOST_IN_USE error will result.
