PCI hotplug and passthrough together supported?

PCI hotplug and passthrough together supported?

[Aaron Dailey]

I’m interested in using PCI passthrough on a PCI device that may not be
present at boot time, but is later inserted.  Is this possible in KVM? 
I believe both passthrough and hotplug are individually supported, but I
couldn’t find an answer about hot plugging a device and then using it
via passthrough.

I’m not subscribed to the mailing list, so please copy me on replies.

Thanks for your help,

Aaron Dailey

hotplug is supported. You can refer to http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM.
