I do not have xe. I am with xm/xl of Xen 4.1.3 open source. I even tried to enable cpufreq_verbose variable in source at xen/drivers/cpufreq/cpufreq.c bool_t __read_mostly cpufreq_verbose = 1; then rebuild/reinstall xen, Unfortunately non of the cpufreq verbose printk logging messages showed neither in xl dmesg or kernel dmesg What I missed? kernel is 3.2.0-1-amd64 from debian testing distribution. As I can see from config it is pvops. cpufreq is qorking normal in Dom0 kernel, but I don't want to use all vcpu for Dom0 or pin them in Dom0.
