It's really much simpler to develop using dev boards instead
of remote machines. Some advantages:
- can do hardware/kernel stuff
You can easily work on kernel or even firmware using KVM guests. The only reason that
I've seen people really needing physical access is to work on graphics card drivers.
- machine is in the same state when you revisit the project over months
I don't remember what I was doing last week... if the machine state changes, after
months I won't even notice :)
I think you can have a dedicated guest... that guest's state won't change.
You can even do virtualization on top of a KVM guest, since nested virtualization is
supported using PR KVM on top of real KVM, which has decent performance.
POWER really needs a cheaper dev board, even if that means cutting a
lot of corners on performance.
I would love to have a P8 dev board on my desk :) on the other hand, it is nice to have
access to big systems, even if it is a shared system.
