Hi. When I try and start a VM I get the following error.

I'm attempting to pass my dual nic pci card, I have a GEN8 microserver iommu and hvm enabled (vt-d etc)

The dual nic is in its own IOMMU but with other stuff:

IOMMU group 1
	[8086:0151] 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor PCI Express Root Port (rev 09)
	[8086:105e] 07:00.0 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06)
	[8086:105e] 07:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet Controller (rev 06)

Error message:

internal error: qemu unexpectedly closed the monitor: 2017-09-20T10:32:37.865244Z qemu-system-x86_64: -chardev pty,id=charserial0: char device redirected to /dev/pts/0 (label charserial0)
2017-09-20T10:32:37.896130Z qemu-system-x86_64: -device vfio-pci,host=07:00.0,id=hostdev0,bus=pci.4,addr=0x0: vfio error: 0000:07:00.0: failed to setup container for group 11: failed to set iommu for container: Operation not permitted

 

any help would be grateful?

 

thanks

 

 

did you try searching for answers to your very common problem?

 

 

(hint: step one is enabling acs override to see if it corrects the issue. you can look at the thread link in my signature for common hp troublesho0ting steps.)
