Hi Chris,
Thanks for your help, that link was really useful. I didn’t know there was work
already done on a SuperMicro machine.
Right now, I’m struggling to get things working with legacy IRQs. The only
configuration where the NIC showed any signs of life was this (by signs of life
I mean a very poor ping with high delay and what looks like polling behavior):
vm2.vm_irqs = [
{"name":"outer_eth", "ioapic":0, "source":0xb, "level_trig":1,
"active_low":1, "dest":12}
];
This is for the 10Gb NIC on a SuperMicro SYS-E300-9D.
What worries me is the ISSUES section in that example you shared:
The SuperMicro machine has 5 IOAPICs. The gigabit and 10Gb NICs are on IOAPIC
1; the code for handling anything other than the 0th IOAPIC seems buggy. Right
now the VM does not get any interrupts.

Are you aware of this kind of IOAPIC problem?
Thanks a lot!
Albert
