Subject: [Qemu-devel] pseries machine does not like older CPUs anymore
Date: Tue, 28 Jun 2016 09:29:33 +0200 [thread overview]
Message-ID: <5772275D.8090400@redhat.com> (raw)
Hi Bharata,
there seems to be a regression with current QEMU master: The pseries
machine does not work with older 64-bit ppc CPUs anymore. With QEMU
2.6.0, it is possible to run:
qemu-system-ppc64 -nographic -M pseries -cpu 970
or
qemu-system-ppc64 -nographic -M pseries -cpu POWER5+
but with QEMU master, I now only get a "Unable to find sPAPR CPU Core
definition" error message and then QEMU quits.
At a quick glance, this seems to be related to the new CPU hotplug
code... so could you maybe have a look?
Thanks,
Thomas
