Hi,
I am facing some problems in delegating a nic from dom0 to domu (a Firewall)
Everythig was runnig fine until:
Jul 9 20:18:59 Icaro2 kernel: irq 16: nobody cared (try booting with
the "irqpoll" option)
Jul 9 20:18:59 Icaro2 kernel: [<c013afef>] __report_bad_irq+0x2b/0x69
Jul 9 20:18:59 Icaro2 kernel: [<c013b1e0>] note_interrupt+0x1b3/0x1eb
Jul 9 20:18:59 Icaro2 kernel: [<c013a845>] handle_IRQ_event+0x49/0x51
Jul 9 20:18:59 Icaro2 kernel: [<c013a900>] __do_IRQ+0xb3/0xe8
Jul 9 20:18:59 Icaro2 kernel: [<c010612c>] do_IRQ+0x43/0x53
Jul 9 20:18:59 Icaro2 kernel: [<c020c0f4>] evtchn_do_upcall+0x64/0x9b
Jul 9 20:18:59 Icaro2 kernel: [<c0104a51>] hypervisor_callback+0x3d/0x48
Jul 9 20:18:59 Icaro2 kernel: [<c010732e>] raw_safe_halt+0x8c/0xaf
Jul 9 20:18:59 Icaro2 kernel: [<c0102c5f>] xen_idle+0x22/0x2e
Jul 9 20:18:59 Icaro2 kernel: [<c0102d7e>] cpu_idle+0x91/0xab
Jul 9 20:18:59 Icaro2 kernel: [<c03256fc>] start_kernel+0x378/0x37f
Jul 9 20:18:59 Icaro2 kernel: handlers:
Jul 9 20:18:59 Icaro2 kernel: [<cd1a2aaf>]
(snd_intel8x0_interrupt+0x0/0x1c3 [snd_intel8x0])
Jul 9 20:18:59 Icaro2 kernel: Disabling IRQ #16
After this, delegated nic stops working on the Firewall.
In Dom0 I have:
