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 library: libvirt 1.2.1 Using API: QEMU 1.2.1 Running hypervisor: QEMU 1.7.0 bnx2x -> firmware 7.8.17 -> driver from kernel 3.12.7 8 VFs are created on the first PF. For each VF, a specific mac address is set manually using "ip

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?

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, since long time, I'm using Xen on CentOS with XL, currently latest CentOS 7 with Xen 4.15 from the CentOS-Xen-Project. For several VMs I have to use SR-IOV, to lower the CPU-usage on Dom0 on the host. CentOS 7 comes to an end, Xen is not supported by RHEL nor RockyLinux anymore, so unfortunately I have to switch to KVM. First step will be now, converting all the scripts for

Hi, My name is Radhika Ghosal and I'd like to participate in this year's GSoC in LLVM. I have been using LLVM for a research project for some time now, and would love to contribute to it! Below are the projects I'm interested in and a few questions; please correct me if I am understanding something incorrectly: - Code Compaction: [1] Is it necessary to implement code compaction

Hi, I'd like to modify MachineBasicBlock contents within a MachineFunctionPass on the basis of how many CPU cycles the assembly instructions corresponding to the MBB take. I'm using the AVR backend and the number of CPU cycles every AVR assembly operation takes is openly available. Is there any straightforward way of getting the opcode mnemonics corresponding to a MachineInstr? I've

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. # virsh net-dumpxml em2net <network connections='1'> <name>em2net</name>

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> 

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

Can you see the USB device in the lxc? My answering assumes you cannot see the USB device in the container. If you can see it, please ignore my answer. According to my understanding, “hostdev mode='subsystem' “ is used with KVM only. We use this if we want to passthrough a device to a KVM virtual machine. After doing that, the host machine will lose control of the device. If container is

When you pass a device in the pci chain (after virsh nodedev-dettach'ing it from host) to the guest, how much is passed without being emulated/abstracted?

Thank you very much for your replies. I tinker frequently with embedded systems and was hoping I could contribute to an `-Os` flag for LLVM or alternately, improving code generation in the experimental AVR backend if there is a willing mentor. As for encoding analysis results in MachineInstr IR, it's a feature I too sorely need in the project I'm working on. Would it be helpful to

Hello,my system info: virsh verison Compiled against library: libvirt 3.9.0 Using library: libvirt 3.9.0 Using API: QEMU 3.9.0 Running hypervisor: QEMU 2.10.90 And i want to pass through my gpu to my window 7 guest with <hostdev>, next line is comand i use: <hostdev mode='subsystem' type='pci' managed='yes' xvga='yes'>

Yes, I can use guest with this way, But when i hot-add my graphics card , Guest will reboot. So i want to try it with <hostdev>. Somehow , If i use "hostdev" without xvga , my screen will be black. If we have no hostdev, do you have other methods can help me to use hot-plug my graphics card? At 2018-01-04 23:27:52, "Laine Stump" <laine@redhat.com> wrote:

Dear Fil, I am not sure if my answer can help you. I had ever asked a similar question to Daniel and I was using a thirty-party card. As a container uses a shared kernel with the host, so hostdev mode='subsystem' doesn't make sense. Maybe you can try to use hostdev mode='capabilities'. Please see http://libvirt.org/formatdomain.html#elementsHostDevCaps Hope this helps Cheng
