Re: [PATCH v2 00/11] hw/ppc/spapr: Remove deprecated pseries-3.0 -> pseries-4.2 machines

Hello,

I noticed removal of old pSeries revisions.

FTR to boot Linux 3.0 I need pSeries-2.7 (already removed earlier).

The thing that broke booting linux 3.0 for me is
357d1e3bc7d2d80e5271bc4f3ac8537e30dc8046 spapr: Improved placement of
PCI host bridges in guest memory map

I do not use Linux 3.0 anymore which is the reason I did not notice this
breakage due to old platform revision removal.

At the same time quemu is sometimes touted as a way to run old OS
revisions. That does not work very well for pSeries.

Thanks

Michal
