Hi all,
I'm working on improving our host CPU detection logic and I'd like to
gather test data for various CPUs and include them in the libvirt's CPU
unit test to make sure I don't introduce regressions.
If you are willing to help me, please, send me the output of the
following command:
grep 'model name' /proc/cpuinfo | head -n1; cpuid -1r
on various i686/x86_64 hosts you might own? Older or unusual CPUs are
more than welcome.
The cpuid tool can be usually found in a package called "cpuid". If your
distro does not provide such package and you are still willing to help,
you can find the sources or binary packages at
http://www.etallen.com/cpuid.html
Private replies are preferred to reduce unnecessary mailing list
traffic.
Thanks a lot for your help,
Jirka

Oh, I forgot I'd also like to see what QEMU/KVM is thinking about the
host CPU. If you have QEMU and KVM enabled on the hosts (or you are
willing to do so), please, also send me the output of the following
command:
qemu-system-x86_64 -cpu host -machine accel=kvm -nodefaults -nographic \
-qmp unix:/tmp/socket,server,nowait & sleep 5; echo \
'{"execute":"qmp_capabilities"}{"execute":"qom-get","arguments":'

Replace qemu-system-x86_64 with the appropriate QEMU binary name
(qemu-kvm, /usr/libexec/qemu-kvm, ...).
BTW, none of these commands should require root privileges.
Thanks a lot,
