</div></div>re0's interrupt is irq11, so it looks like re0 never consid=
ers the<br>
interrupt is for him. =A0Would it be possible that you could change the<br>
emulated network device?<br>
<br>
Other option, set hw.ioapic_enable=3D"0" in /boot/loader.conf<br>
I am considering disabling I/O APIC on all virtual machines.<br>
