And I believe we still need part of the second patch --- the one that
removes call to xc_domain_irq_permission() for PV guests (after your
patch is applied): this call will fail because xc_physdev_unmap_pirq()
above it will cause hypervisor to do unmap_domain_pirq()->irq_deny_access()
What call to xc_physdev_unmap_pirq ? I see one in the PV path.
(Now with Reply-all, sorry)
At the skip1 label.
The error is:
[root@ovs105 libxl]# ./xl pci-detach pvlinux 0000:09:00.1
libxl: error: libxl_pci.c:1305:do_pci_remove:
xc_domain_irq_permission irq=17: Invalid argument
[root@ovs105 libxl]#
Thanks.
