your patch - it now core dumps for 128 virtio-devices.
You can find the output here - https://pastebin.com/W4DXZ6J5.
My config is attached to this email.

Hi Gal,
Brilliant - will test this in the next day or two.
Hopefully this will help resolve the issues I reported last summer.

Even if I am not aware of how much time would take to init a bare-metal

So I repeated the testing for 64, 128, 256 and 512 ports. I ensured the

That's strange. Please ensure the virtio devices are working in

Let us know any problems you see.
Not sure what yet, I will try scaling it
Hi Marcel,
You can use multi-function PCIe Root Ports, this will give you 8 ports
per slot, if you have 16 empty slots (I think we have more) you reach
128 root ports.
Then you can use multi-function virtio-net-pci devices, this will
give you 8 functions per port, so you reach the target of 102
Hi folks,
I am trying to create a VM that supports hot-plugging a large number of
virtio-net-pci device,
up to 1000 devices initially.

Both with limitations.

It looks like using a
