Thanks for the suggestion, after adding printk to all the routines of xc_altp2m_set_vcpu_enable_notify, it turns out that the problem is because the check of is_hvm_domain() <http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/arch/x86/hvm/hvm.c;h=615fa8908375aaad452e2be69fe183c2a12b82bf;hb=b24ad7ba911a9f0688ab179736476e44c52144f1#l6204> failed in function do_altp2m_op() <http://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=xen/arch/x86/hvm/hvm.c;h=615fa8908375aaad452e2be69fe183c2a12b82bf;hb=b24ad7ba911a9f0688ab179736476e44c52144f1#l6179>. However, I've already configure the VM to build as a HVM by adding option "builder=hvm" in the config file, but for unknown reason the .printk of domain->type is guest_type_pv. I've tried both windows and linux as the guest VM, both failed for the same reason. Any ideas?
