Hmm, not sure. None of the existing lifecycle documentation contains

Good point. I moved these new options into a new enum and adjusted the
code accordingly.
V2 attached.
Thanks!

Subject: [PATCH] Add actions to virDomainLifecycle enum
Xen supports on_crash actions coredump-{destroy,restart}. libvirt
cannot parse config returned by xend that contains either of these
actions
xen52 # xm li -l test | grep on_crash
(on_crash coredump-restart)
xen52 # virsh dumpxml test
error: internal error unknown lifecycle type coredump-restart
This patch adds a new virDomainLifecycleCrash enum and appends
the new options to existing destroy, restart, preserve, and
rename-restart options.
V2:
- Create new enum to hold valid on_crash options
- Reject coredump-{destory,restart} for on_{reboot,poweroff}
