Title:
kvm disabled-by-bios flag should be displayed in /proc/cpuinfo
Status in CPU-Checker:
Triaged
Status in linux package in Ubuntu:
Won't Fix
Bug description:
The kvm-ok utility helps users determine if their hardware is capable
of running hardware accelerated KVM virtual machines.
The easy part of the check is looking for (vmx|svm) in /proc/cpuinfo.
This is not entirely sufficient, however, as users (or OEMs) can
disable VT arbitrarily in BIOS, rendering VT unusable. However, the
kernel continues printing (vmx|svm) to /proc/cpuinfo's flags.
The kvm module detects this, though, on module load, and adds a printk
to dmesg:
[ 15.147129] kvm: disabled by bios
The dmesg log is not ideal, obviously, as these logs roll eventually.
Furthermore, the story in /proc/cpuinfo is clearly not the full
picture.
What is needed, then, is the display of an additional flag in
/proc/cpuinfo, noting that svm_disabled|vmx_disabled, when the kernel
determines that this is so.
