  • Thread-topic: Error in Xend-API method VM_set_actions_after_crash

Xend-API defines the method VM_set_actions_after_crash with vaild action
names coredump_and_destroy, coredump_and_restart,... . These values have to
be converted into internal representation “coredump-destroy”, “coredump-restart”, …
otherwise start of the domain is rejected.
Same error occurs, if I try to create a VM using the Xend-API with
actions_after_crash set to coredump_and_destroy.
