Hi! I'm working on top of the zmq_samples example, trying to set up 2 Ethernet devices on 2 of the 3 VM's.
The passthrough for both VM's has been done, and both detect the NICs. For more information, this is the setup for the irqs in the camkes file:
vm0.vm_irqs = [
{"name":"inner_eth", "ioapic":0, "source":0xb, "level_trig":1, "active_low":1, "dest":10}
];
vm2.vm_irqs = [
{"name":"outer_eth", "ioapic":0, "source":0xb, "level_trig":1, "active_low":1, "dest":12}
];
My problem is related to having the same IRQ11 in both e1000e devices. I can't control this; that is what QEMU provides.
When I set up the first NIC in any VM, say VM0, doing ifconfig eth1 up, it works correctly, but when I try to bring up the other one, VM2, the whole system freezes for a moment. Then VM0 complains about this:

Any interruption goes to VM2; they all go to VM0 but are not intended to go to that one, so they are ignored.
Any thoughts on this would be appreciated!
