From Debian Xen Wiki: "The new 2.6.32 kernel images have paravirt_ops-based Xen dom0 and domU support, please use them: " so, the kernel what I use is a pv_ops kernel.> Hello, > >> CPU is an i7 920 and have used the kernel from debian lenny backports: >> > i think you need pv_ops kernel. > > Stefan Kuhne-- Greetz _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-devel] Re: [Xen-users] xen 4.0 and cpufreq with pvops dom0 kernel
Xen needs a suitably configured odm0 kernel to push cpufreq info down into it. My guess would be that the new dom0 kernel that was installed is missing the relevant support, or it is not configured into the build. K.
