Hi, I got a problem when prepared to pass-thru 82576 ethernet card with SR-IOV support. The 82576 card is build-in on the board. When loading igb driver for the card, dmesg show some errors like: pci 0000:05:00.0: BAR 10: can''t allocate mem resource [0xfbf00000-0xfbefffff] . igb 0000:05:00.0: not enough MMIO resources for SR-IOV igb 0000:05:00.0: Failed to initialize

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>

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

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

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> 

Hi, Greg, Eddie, I found that in SR-IOV + HVM environment, ping latency depends on ping interval. The NIC is Intel 82576 (1000Mbps), server uses xen-4.0.1, domain-0 is kernel-2.6.32 and HVM is kernel-2.6.31. The server and client are connected through a 1000Mbps switch. The data is as following: # ping -i 1 192.168.0.21 PING 192.168.0.21 (192.168.0.21) 56(84) bytes of data. 64 bytes from

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.

This patch adds experimental VMDq support (AKA Netchannel2 vmq) to the ixgbe driver. This applies to the Netchannel2 tree, and should NOT be applied to the "normal" development tree. To enable VMDq functionality, load the driver with the command-line parameter VMDQ=<num queues>, as in: $ modprobe ixgbe VMDQ=8 You can then set up PV domains to use the device by modifying your VM

Hi, I am working with a westemere based server. I need to find out if the NIC installed there supports SR-IOV - what would be the best way to determine that?

Hi all, I''ve fetched the xen 4.0.1 source from the usual spot and have git''d the stable dom0 source (recently) from the jeremy repository, have successfully built and installed each of these on my VT-x and VT-d capable x86_64 system, over a fedora 14 installation. Most of the features seem to be running just fine, but I''m having a real problem getting the virtual

The SR-IOV patches for the upstream kernel are finally in-tree. This patch backports some minor changes that appeared in the upstream kernel after the Dom0 patches were checked-in.

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

Greetings, Following patches add SR-IOV capability support to the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective. [PATCH 1/4 v2] PCI: introduce new base functions [PATCH 2/4 v2] PCI: support ARI capability [PATCH 3/4 v2] PCI: support SR-IOV capability [PATCH 4/4 v2] PCI: document the change Thanks to Randy Dunlap

Greetings, Patches to support Single Root I/O Virtualization (SR-IOV) capability are available for the Linux 2.6 development tree. KVM and Xen supports will come soon! --- Single Root I/O Virtualization (SR-IOV) capability defined by PCI-SIG is intended to enable multiple system software to share PCI hardware resources. PCI device that supports this capability can be extended to one Physical

Hi, We recently purchased some HP Gen8 servers with Broadcom BCM57810 NIC controllers. I am running CentOS 6.2 on these servers configured as KVM hosts. Has anyone gotten the Broadcom chips to run with SR-IOV on CentOS 6.2? Any clues on how to get it working? I see from the Broadcom glossy marketing docs that this chip supports SR-IOV, but I cannot find a procedure for configuring it. The

I have an intel 82576GB SR-IOV network card, and I''m trying to pass a function through to a PV domU. Things seem to be going right, but the function I pass through never shows up in an lspci on the domU. I''m successfully hiding the function in dom0, and it shows up in "xm pci-list-assignable-devices" I''ve tried assigning the function to my domU using both the

I''m currently unable to make it fully work. If there are successes out there that are willing to share config, etc, I''d really like to compare. My current efforts: o physical nics mapped to linux HVM guests work, get network access o virtual nics (sr-iov functions) get mapped to linux HVM guests, report link up, but do not get network access (IRQ black hole??)
