I though PV domain would have been captured by..
xc_get_hvm_param(ctx->xch, domid, HVM_PARAM_CALLBACK_IRQ, &pvdriver);
if (!pvdriver .. )
Yes having is_hvm is much better than the hard coded values I have changed that bit of code see attached patch. I tested with hvm with and with out pv drivers. seems to work. Would be appreciate if someone can test in full pv domains.the if (/* hvm */ 0) is because the function never properly tested if the domain is hvm or not. nowadays you have is_hvm(domid) function that can handily replace the hardcoded value.
