Xen-API already specifies these actions for the 'on_crash' domain exit event. This patch makes them available for use in traditional domU config files and through the xm tool as well. Signed-off-by: Jim Fehlig <jfehlig@novell.com>

# for a domain to stop: poweroff, reboot, and crash. For each of these you

|
|
#
|
|
# "destroy", meaning that the domain is cleaned up as normal;
|
|
# "restart", meaning that a new domain is started in place of the old
|
|
# one;
|
|
# "preserve", meaning that no clean-up is done until the domain is
|
|
# manually destroyed (using xm destroy, for example); or
|
|
# "rename-restart", meaning that the old domain is not cleaned up, but is
|
|
# renamed and a new domain started in its place.
|
|
#
|
|
# In the event a domain stops due to a crash, you have the additional options:
|
|
#
|
|
# "coredump-destroy", meaning dump the crashed domain's core and then destroy;
|
|
# "coredump-restart', meaning dump the crashed domain's core and the restart.
