These are bare text files which tracks transition between different states of libvirtd, what it has tried to achieve, etc. Monday & Tuesday, June 22/23, 2009. However, considering that the boot order is most likely dependent on a higher level application (the app hosted in the guest) and it's dependencies, does it really make sense to add that integration to libvirt/libvirtd? To truly get a staggered order, it should really know something about the application preferences etc. The network boot feature enhances the s390x ipl device and the s390-ccw bios with support for booting via a virtio-net boot device. Assuming a recent enough libvirt, you should be able to create a virtual machine based on q35 and attach the devices to pcie-root (bus 0). QEMU provides the userspace emulation, KVM provides the kernel acceleration, and libvirt provides an abstraction layer for applications to interface with various hypervisors at an API level.
