cannot start domain with SR-IOV interface
Hi,
I've been using libvirt (versions 0.9.11.5, and recently upgraded to
0.10.2), and have been attaching an SR-IOV VF to my VM with the following
device configuration:
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address domain='0x0000' bus='0x07' slot='0x10' function='0x0'/>

SR-IOV pool with static MAC address and vlan
Hi Paul,
You can set the static MAC address and VLAN in the interface section of the
VM xml.
So it will not change even when the VM shuts down and restarts.
VM interface xml:
<interface type='network'>
<mac address='52:54:00:85:e2:cd'/>
<source network='hostdev_net'/>
<vlan>
<tag id='42'/>
</vlan>

SR-IOV pool with static MAC address and vlan
I'm planning to set up a libvirt/kvm system using a card with SR-IOV
support. I'd like to use the vf pool option rather than statically
assigning a vf to each vm. However, I'd also like each vm to have a
static MAC address and I have multiple VLANs they will be on.
I found in the documentation a syntax for specifying a MAC and a vlan
when the vf is statically assigned, but I don't

SR-IOV Pool Availability
If I'm using the SR-IOV Pool assignment method (from
http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition
), how would I check how many virtual functions are already in use?
Is there a method other then looping through all the active guests and
determining if they're using the SR-IOV interface?

Re: SR-IOV Pool Availability
I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4.
Hi Hongming, I'm hoping you can please help with two issues:
1. The pool works, but I transparent VLAN with the pool does not. I
have to manually run "ip" afterwards to get it to work.

SR-IOV: no traffic isolation between VFs with Broadcom 10Gbps cards
Hi all,
I'm testing on debian/unstable SR-IOV feature with Broadcom BCM57810
cards and KVM hypervisor:
Compiled against library: libvirt 1.2.1

Using API: QEMU 1.2.1
Running hypervisor: QEMU 1.7.0

Adding a VLAN tag to a libvirt SR-IOV VF network using the "virsh net-update" command
Hi all,
How do you add a VLAN tag to a libvirt SR-IOV VF network usingthe "virsh net-update" command? I couldn't find the section to passto the "virsh net-update" command to add the VLAN tag.
I have the following libvirt network defined for a SR-IOV VF:
<network> <name>GE0-0-SRIOV-1</name> <uuid>7bc67166-c78e-4bcf-89ee-377dd9086631</uuid>

I tried to attach the device using following xml

About the vfio error when using SR-IOV
Hi, All
I want to use the SR-IOV of intel 82576 NIC.
I enabled IOMMU and VT-d and SR-IOV in BIOS.
And enabled VT-d in kernel.
The OS information is bellow:

sr-iov on Intel 82576 and rhel 7 - would not work
hi everybody
a windows kvm guest would not start, process gets killed with:
Out of memory: Kill process 21984 (qemu-kvm) score 44 or
sacrifice child
I really don't know where/what I might be missing, config
seems fine, everything looks ok - I only am not sure, do I
need to first stub a SR-IOV device like regular passthrough?
I'm trying sr-iov, having one NIC left to the host and the

Re: Sr-iov passthrough - no packet arrive to guest
I can see from different post that if working with sr-iov, i should work
with vlan
Is this an obligation to work with vlan if working with sr-iov?
If not according to which parameter will the different vf get the
traffic.
Let's say i declare max_vfs=7, how will the traffic be seperated between
the vm?
However till i get an answer i tried to work with vlan
And i still don't get

IOV / SR-IOV / MR-IOV for non-network hardware?
I've been looking for real-world examples of this for a long time --
mainly because I'm trying to decide whether to restrict my build-options
to using only components which are all compatible with IOV.
I'm thinking that the constraint would be worth it,
if IOV could provide a significant performance benefit for non-network
peripherals such as storage, video processing, etc. (compared
