The patch to hypterstart was also submitted to the upstream project.
It fixes these errors/warnings:

For VMs masquerading as kernels, we need a kernel and initrd. runv
uses hyperstart for this purpose so we add the recipe here. Once
built, the kernel and initrd are installed to where runv can find
them automatically.
