Re: [PLUG] download from WHERE?

I saw that IBM had done that...  good stuff.

KVM or hyper-visors on bare metal were promised like flying cars awhile back but I think we'll see that in some form soon.  If I had to bet though, I think ARM in partnership with <insert someone here, my bet is Google> might be the ones to pull it off.

First up though, is virtualization x86_64 on ARM v8 solidly.  That makes me tingle....

worth noting that IBM has KVM on bare metal:
https://www.ibm.com/developerworks/linux/tutorials/l-ibm-powerkvm-system-bring-up/

well. "bare metal". it's sort of that. at a *guess*, their "bare metal"
implementation is just the linux kernel and libvirt running in an
initram image. (initial ramdisks aren't JUST for assisting booting to a
full system!)

i bet if anyone brings baremetal kvm to the general public, it'd be the
Coreboot folks. it shouldn't be *that* big of a step.
