Thread-topic: [Xen-devel][PATCH] Change vcpu_avail type to hex string when passing to xc.hvm_build()
Hi Keir, 
        I'm sorry I am not familiar with C/Python inter-programming...
Actually I have thought of this patch for a looong time on how to make it 
clean...
But it seems that system doesn't work correctly. I assigned 10 vcpus for guest, 
however
after guest boots, it only has 8 vcpus. However it is correct if I assign 128 
vcpus.

Thanks!
Dongxiao
