- I am trying to get SR-IOV working with KVM on RH6.4.
I have SR-IOV enabled FW/SW on my NIC's.
Nov 6 09:17:51 hostname kernel: Intel-IOMMU: enabled
This is the section of XML pieces I'm adding to the VM guest.
<interface type='hostdev' managed='yes'> <source> <address type='pci' domain='0' bus='0x1' slot='0x0' function='0x1'/> </source> </interface>
However, as soon as I try to start the VM, KVM/libvirt still complains that "I/O MMU" is not found, below is guest log from
2013-11-06 16:53:46.649+0000: starting up LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/libexec/qemu-kvm -name guestname Domain id=6 is tainted: high-privileges char device redirected to /dev/pts/0 No IOMMU found.
