Re: [libvirt] [PATCH 31/36] cputest: Add support for MSR features to cpu-gather.sh

This patch adds an inline python code for reading MSR features. Since reading MSRs is a privileged operation, we have to read them from /dev/cpu/*/msr if it is readable (i.e., the script runs as root) or fallback to using KVM ioctl which can be done by any user that can start virtual machines. The python code is inlined rather than provided in a separate script because whenever there's an issue with proper detection of CPU features, we ask the reporter to run cpu-gather.sh script to give us all data we need to know about the host CPU. Asking them to run several scripts would likely result in one of them being ignored or forgotten.
