[Qemu-devel] KVM guest cpu L3 cache and cpufreq

Hi,

I noticed that the l3 cache size of a guest /proc/cpuinfo is not the same as
the l3 cache size of the host.

I did not found any references to this in the qemu and KVM code.

Is the size of the guest L3 cache fixed in hardware ?

Can a patch be written to set it ?

Similarly I noticed that the frequency in the guest was not reflecting the
frequency scaling of the host.

Could anything be done for this ? 

Best regards

Benoît
