[Qemu-devel] [PATCH 0/2] QEMU maxcpus support v2

[Jes Sorensen]

Hi,

Another update to the maxcpus patch. Gleb pointed out that I was
enabling all processors in the MADT, which clearly wasn't my
intention. My brain had obviously already left for vacation when
I wrote it.

Anthony, any chance you could try this and see if it fixes your
Ubuntu guest problem?

Specifying maxcpus= allows the user to cap the limit of possibly cpus
of the system, as opposed to -smp which specifies the number of
running cpus at startup. This allows us to build BIOS tables
accordingly when trying to scale up in size, and it also allows for
the BIOS to build smaller tables when not needed.

Cheers,
Jes
