The makedumpfile command, used to manually
trigger a vmcore dump file is documented to support dump levels
from 0 to 31 using the -d
switch. Notably, the
manual page states that it is possible to specify a value higher
than 1 on an x86_64 machine running the Xen hypervisor. This is
not the case for Oracle VM Server. Only the values 0 and 1 can be
specified for this parameter, or a vmcore file is not generated.
Workaround: There is no workaround. Only use dump levels of 0 or 1 if using the makedumpfile command.
