Hi, We are using pci-assign option for device passthrough; we observe that the interrupts are still going through host and cpu utilization is very high. We unbind the NIC card from host driver and use the following command for device passthrough: qemu-system-x86_64 -m 512 -net none -hda xxx.img -device pci-assign,host=01:00.0 Could you please let us know why cpu utilization is very high even though we do direct device assignment? Also, could you please let us know where to find more documentation on pci-assign. Thanks, Spoorti
