the nic of virtio3, virtio4 did not work, because IRQ #11 is disabled.
IRQ11 is disabled, because there are 100000 times interrupts is unhandled.
11: 100000 0 0 0 0 0
0 0 IO-APIC-level virtio3, virtio4
there are three pci device routed to IRQ 11. 00:01.2, 00:03.0, 00:07.0.
the guest os is boot from network.
why there are 100000 times interrupt is unhandled?
