It may be necessary to change properties of a virtual machine that cannot be changed using the OVM Manager User or Command Line Interfaces.
For example, if a vmcore needs to be obtained from a vm, the vm.cfg "on_crash" may need to be set, for example to "on_crash = 'coredump-restart'".
This will be effective when the vm is restarted. Note the vm must be stopped, either by the manager or an "xm destroy" command on the ovm server, prior to being started again. A "reboot" or equivalent command issued from within the vm will not cause changes to the vm.cfg to be implemented.
However, the next time the vm is changed using OVM Manager, any manual changes to its vm.cfg will be lost.
