virt-manager/virtman-allow-destroy-from-shutdown-menu-of-crashed-vm.patch

Reference: bnc#875111
Steps to get a KVM VM in the crashed state:
1) Install a sles12 KVM VM
2) Manually edit the XML and add/modify <on_crash>preserve</on_crash>
3) In virt-manager add the panic device (Details->Add Hardware)
4) Edit the VM's /etc/default/grub file and remove the crashkernel information
   and then run grub2-mkconfig /boot/grub2/grub.cfg.
5) Start the VM and within the VM's terminal type "echo 'c' > /proc/sysrq-trigger"
