Add support for limiting guest coredump
Sometimes when guest machine crashes, coredump can get huge due to the
guest memory. This can be limited using madvise(2) system call and is
being used in QEMU hypervisor. This patch adds an option for configuring
that in the domain XML and related documentation.
