similar to: Attach / detach problem for passthrough/SR-IOV in libvirt

Hi all I just encountered a problem in libvirt while was trying to attach and detach a sr-iov vf to my VM The version of my libvirt is 1.1.1-0ubuntu8.5 I tried to attach the device using following xml <interface type='hostdev' managed='yes'> <mac address='5c:01:fd:12:34:58'/> <source> <address type='pci'

Hi guys. These days I'm doing research on SR-IOV & Live migration. As we all know there is big problem that SR-IOV & Live migration can not exist at the same time. I heard that KVM + SRIOV + MacVtap can solve this problem. So I want to try. My environment: Host: Dell R610, OS: RHEL 6.4 ( kernel 2.6.32) NIC: intel 82599

Hi, I managed to get SR-IOV with an Intel I350 NIC to work.For this I followed the documentation on this page: https://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition But as I have more VMs then VF on the NIC I also have a bridge wich serves the other guests. As I run Debian Buster as host I followed the documentation here:

Hello I have a problem with VDI already attached RW in the "adding tag" in blktap2. This issue is on all hosts in pool with attached lvmoiscsi SR.

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

i've reported this issue before, so i guess this is a regression. looks like the python bindings for 0.9.3 are leaking file descriptors: root at cloud1:~# python Python 2.6.6 (r266:84292, Dec 26 2010, 22:31:48) [GCC 4.4.5] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import libvirt >>>

Hi, I'm a new R user. My goal is to do a variogram using geoR. I started by trying to do the example in the geoR Illustrative Session using my own data. I am able to read in my Ascii data using: D <- matrix(scan("file.dat", n=530*3), 530,3, byrow=TRUE). Then I use: as.geodata(D, coords.col=1:2, data.col=3) to make the object D geodata. I check the descriptive statistics,

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

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

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

Hello, Is there a HowTo or tutorial about the configuration of VMDq or SR-IOV with XEN? Thanks in advance.

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??)

Hi, (Already asked this on the intel wired forum: http://communities.intel.com/message/185413#185413 but some of those questiones are XEN specific, which might be why theres no response ;-) I have doubts if SR-IOV will provide the required features compared to nPAR. SR-IOV seems more flexible, but I''m not sure if performance and features are the same as nPAR. Servers will be Dell M620

Hi, This is regarding SRIOV in Rhel7. I have added intel_iommu=on in grub.cfg file. When I attach Virtual Function to VM and I try to poweron the VM, I get the below error: [root@Dell-Rhel7 ~]# virsh start rhel64x64GA error: Failed to start domain rhel64x64GA error: internal error: early end of file from monitor: possible problem: qemu-kvm: -device
