Hi, Can anyone please help with the following: I have a running instance with interface <interface type='bridge'> <mac address='fa:16:3e:ba:a4:67'/> <source bridge='br100/> <target dev='vnet0'/> <model type='virtio'/> <filterref filter='nova-instance-instance-00000001-fa163ebaa467'/>

Dear Yalang, that did the trick. If I look in the NAT table of the bridge I can see the generated rules. Probably wouldn't have though about that ever. Thanks a lot!

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

Hi, I'm trying to configure nwfilter for KVM, but so far I haven't managed to figure out a working configuration. Network setup: The dom0 (Debian 7.1, kernel 3.2.46-1, libvirt 0.9.12) is connected via eth0, part of the external subnet 192.168.17.0/24, and has an additional subnet 192.168.128.160/28 routed to its main address 192.168.17.125. The host's subnet is configured as bridge

Greetings, I've setup an vm with openwrt in it, defined a isolated lan between the vm and the host and booted the vm up. I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest. I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see: dagg@NCC-5001D ~ $ dhcpcd vnet0 DUID

Hey, I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows: ____ ____ / VM1\______br0_______/ em1\ \____/ | \____/ | _|_ /VM2\ \____/ virbr0 is the virtual network switch VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively. em1 is the default

I need to use an existing windows 7 installation in a virtual machine form a libvirt host running Ubuntu 12.10. Windows 7 installs on two partitions. There a 100MB boot partitiona and then the main partition for the installation. If I boot the laptop (which dual boots), I can select Windows 7 and boot it just fine, or alternative Ubuntu. If I select /dev/sda1 in the virtmanager as the source

Hi, I try to add 2 VF functions to VM via network. Livirt networks: vnet0: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf dev='eth0'/> </forward> </network> vnet1: <network> <name>vnet0</name> <forward mode='hostdev' managed='yes'> <pf

Hi, I'm trying to migrate a VM from one libvirt 0.7.6-1 (qemu-kvm 0.11.1+dfsg-1) to another libvirt 0.7.6-2 (qemu-kvm 0.11.1+dfsg-1) connected with SSH , i have followed pre requite (same shared, same path, same network conf ...) . But when i migrate , i have following error : operation failed: /migration to 'tcp:x.x.x.x:49157' failed: migration failed DETAIL : Unable to migrate

Hi, I want to migrate from vmware to KVM. Therefore I have installed debian stable (lenny) and create two virtual machines (KVM). Both (XP as well as Vista) running fine. After upgrading to debian testing (sqeeze) both XP-guest as well as Vista-guest didn't start anymore. Both are failing during preparation, probably because of a network-problem. I will give XP as an example: cat

I am running NOX controller with a python script that prints out the destination mac and the source mac for each packet arriving at the now controller and then floods it out. So here's what happening: With em1 connected, all the packets that arrive at em1 are coming to the controller and printing out the details. However, without em1 connected to the OVS, when I have the following setup:

How does the libvirt deal with the vnet mac address? Greetings, if I establish a network for the VM (hypervisor is KVM) using bridge in the virt-manager , a vnet0 device is created . There are some relationships about mac address between the vnet0 device in the hypervisor and the ethX device in the VM, for example : the mac address of vnet0 is FE:54:00:84:E3:62 the mac address of ethX in the VM

Hi all: It takes more than 10 seconds to create a vm on a Dell R830 machine, but it takes less than 2 seconds on other machines. This is not normal, so I turned on the debug log for libvirtd. I analyzed the log and found that the time was spent on libvirtd calling qemu. Thread 95225 calls the qemuProcessLaunch interface at 14:22:30.129 and then builds the emulator command line, but the

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:

Hello, I am experiencing system hangs when running NFSv4 over a tinc VPN. I don't know if the problem is with NFS or tinc and would appreciate any suggestions on how to narrow down the culprit. Unfortunately I cannot simply run NFS directly over TCP -- the participating systems are connected only over an open network. The configuration is as follows: I have a master server

Hi list! I would like to modernize my server at home which is still running Shorewall 3. The server will be running CentOS 6.2 but i also want to use KVM virtualization to run a Windows host on the same box that i can log in to remotely. I looked through the documentation samples on the shorewall site and found several bridging configurations but they do not match my setup, yes it will

Hi, today a couple of Hypervisors got restarted due to a power outage. While the systems and the VMs on the are running fine multicast traffic between the guests is no longer working. I generate multicast udp packet using iperf in the guest and check on the host using tcpdump: tcpdump vnet0 => multicast packets are visible tcpdump vlanbr8 => multicast packets are visible tcpdump em1.8
