The pci=nomsi actually seems to create problems for us when using pci passthrough. We could not get more than 2.5 Gbit from a domU, using netback/netfront. It was suggested that we use pci passthrough to get the full 10Gbit. However dom0 and domU crashes periodically with: kernel irq 60: nobody cared (try booting with the "irqpoll" option) kernel Pid: 0, comm: swapper Not tainted Booting with irqpoll has no effect. So I tried to upgrade the firmware on the qlogic cards to 1.09.22 - no change. Qlogic's latest firmware is 1.09.65 - but is not installable on the DELL oem cards. I was not able to downgrade the qlogic driver in linux 3.2 to 5.0.24 from 5.0.25 as suggested in this thread, the driver will not compile - struct dev_mc_list is no longer defined in netdevice.h. As far as I can tell the pci=nomsi disables the irq handling needed for pci passthrough. Could someone confirm this? Could someone also clarify if this is a qlogic driver issue or a xen issue.
