Public bug reported:
Everything about SR-IOV on this machine are ready. I can run a VM perfectly
with SR-IOV using this command:
kvm -name abc \
-uuid ca3e15a4-8220-94d1-ca8f-81a065eb4dd9 \
-boot c \
-m 2048 \
-nodefconfig -nodefaults \
-hda abc.qcow2 \
-net nic,vlan=1,macaddr=52:54:00:64:a2:b3,model=e1000 \
-net tap,vlan=1 \
-vnc :30 \
-device pci-assign,host=06:10.0 \
-device pci-assign,host=08:10.0
---------------------------------------------------------------------
06:10.0, 08:10.0 are VF PCI buses, but when I add these two PCI devices
to VM it cannot boot up, showing this message:
Error starting domain: Requested operation is not valid: PCI device
0000:06:10.0 is not assignable
Traceback (most recent call last):
