Re: [libvirt] [sandbox][PATCH] config: select specific kernel

Added parameters to select a kernel through the release version and path to binary. When setting kernel release version, the module search will be done in  /lib/modules/<release>/kernel . Also, by default, after setting the kernel release version the default kernel image path will be /boot/vmlinuz-<release> The two default to the running configuration: /lib/modules/`uname -r`/kernel and /boot/vmlinuz-`uname -r` kver didn't seem suggestive enough; I used kernrelease and kernpath. To be changed if necessary. Also removed utsname inclusion wherever it wasn't used at all anymore
