I am thinking about fixing bug 155468 and see that HYPERVISOR_vcpu_op(VCPUOP_intialize, cpu, &ctxt) returns -EINVAL. If I understand XEN code correctly, it could happen if we had wrong vcpu_info. But I am not sure, wrong values in vcpu_guest_context_t also can be involved. Did anyone try to fix it or just has any additional information about this issue? -- Best Regards Daniil Cherednik
