Hi, I just installed FreeBSD 9.0-release / amd64 on a new machine (Acer Aspire X1470). I installed from a usb memory stick (the default amd64 image), which I booted by pressing "F12" and selecting it from the boot menu on the machine. I installed on a SSD (which replaced the hard drive originally in the machine), using the default scheme for 9.0 (GPT). The installation was painless (many

Hi, I'm having trouble starting a VM with vhostuser interfaces. I have a simple configuration where a VM running Debian has 1 vhostuser interface plugged into an OVS switch where a DPDK interface is already plugged in. $ ovs-vsctl show: Bridge "switch1" Port "switch1" Interface "switch1" type: internal Port "1.switch1"

Hi Cole & Michal, I'm sorry for my late response, I just end my journey today. Thank your response, your suggestion is very helpful to me. I have added Michal in this mail, Michal helps me review my initial patchset. (https://www.spinics.net/linux/fedora/libvir/msg191339.html) All concern about this feature is the XML design. My original XML design exposes more details of Qemu.

I am planning to configure vlan on vhostuser interfaces in the libvirt xml, it throws out error. Does this configuration is supported ? I can install higher version if required. *Error:* unsupported configuration: an interface of type 'vhostuser' is requesting a vlan tag, but that is not supported for this type of connection *Libvirt version:* [redhathost@qemu]# libvirtd --version

Hi Guys, And I want to add the vhost-user-scsi-pci/vhost-user-blk-pci support for libvirt. The usage in qemu like this: Vhost-SCSI -chardev socket,id=char0,path=/var/tmp/vhost.0 -device vhost-user-scsi-pci,id=scsi0,chardev=char0 Vhost-BLK -chardev socket,id=char1,path=/var/tmp/vhost.1 -device vhost-user-blk-pci,id=blk0,chardev=char1 What type should I add for libvirt. Type1: <hostdev

Hi, I want to use this qemu command '-object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on' with libvirt but i can't find the 'mem-path' and 'share' in the documentation. because the vhost-user backend based on 'share=on' parameter and libvirt support vhostuser i guess there maybe another way to support this parameter? this is my xml:

Is there a setting to allow/disable spoof checking and trust on VF from SR-IOV device? Lookin at https://www.libvirt.org/formatdomain.html#elementsDriverBackendOptions can this be done through the driver element? *<driver name='vhost' txmode='iothread' ioeventfd='on' event_idx='off' queues='5' rx_queue_size='256' tx_queue_size='256'>

I have installed OVS from sources using the installation steps mentioned on this link: http://docs.openvswitch.org/en/latest/intro/install/general/ I had installed libvrt, KVM, QEMU and all the necessary packages using apt-get. My KVM-QEMU hypervisor has been running well. To add a VM with the port attached to OVS bridge I changed the XML domain file as per the instructions on this page:

Spot on! The script qemu-ifup was indeed the cause of the problem. It's a dummy script that only does "exit 0" and it was apparently needed in the past with old versions of libvirt. I see examples on the net where it is used to configure interfaces with shell commands. I don't need it. I see that everything works fine without the <script

The HyperV network driver can do scatter/gather but does not do checksum offload. Since the network stack requires checksum offload to do direct transmit (sendfile), netdev_register produces a message when driver is loaded.

I think we could just disallow this. If we get to the point of wanting mask-aware library
