Hi,
How can I make use of "multifunction" functionality to support more than 32 virtio devices in QEMU through libvirt ?
It isn't supported because it doesn't work with hotplug.
And to be clear, on the QEMU side, we really need to have a high level modelling of a multifunction device. So the following should be possible: -device virtio-blk-pci,ports=4,drive0=hda,drive1=hdb,drive2=hdc,... Then libvirt could add/remove all ports in a single operation. Regards, Anthony Liguori
Are there corresponding changes in libvirt ?
To increase the number of devices in a usable manner, we we're waiting for QEMU to support either
- A virtio block controller with multiple disks - A PCI bridge to allow> 28 PCI devices
