25096 : Added config file for qemu x86-84 to manipulate runqemu into passing jailhouse hardware check
added a /conf/machine/qemux86-64.conf file
so this is how the configuration looks , this needs to be refactored further

bitbake will show a parse error if you keep the declare a config as :
QB_SYSTEM_NAME: “qemu-system-x86_64”
it needs to be like this -
QB_SYSTEM_NAME = “qemu-system-x86_64”

Simon says I cant sign off as d__ep__th , has to be my real name :(
Learned something cool, adding the "SPEC - 3507 " in your commit message links it to that specific spec in jira
Realized that several layers might have a similar config
and that the compiler has ways to priororitize config from one layer over the other depending on the suffix applied on that
now the suffix can be - _append or _qemux86-64
for example- the conf QB_CPU_KVM has 4 declarations and we need to override the priority , so we added
_qemux86-64 as suffix

moved the config file to templates/feature/jailhouse/50_jailhouse.inc
Why? well, it gets added in the local.conf of your build folder , its easier to then manipulate the file from there
this is how it looks in the local.conf file

learned to use mid-night commander (its so efficient , like wow, wish I started using this a couple of months ago,
I was using Vim but in vain!)
I was using Vim but in vain!)
Currently , runqemu works enough to start the boot but ends with kernel panic 50_local.conf.inc still requires refactoring.
My documentation game needs work , also thinking of changing the UI of my doc blog page to something more simple because
I ended up reading a lot of guides in the last month about the ins and outs of the kernel and it kinda makes me wanna step down
from the whole star wars flair I was trying and adhere to the kernel hacker demographic.
