Greetings, I have two vms, one is a router and the other one is a client, for some reason, the client vm is unable get ip via dhcp from the router vm. here are outputs: vm1.xml: <interface type='bridge'> <mac address='52:54:00:54:78:be'/> <source bridge='virbr0'/> <model type='virtio'/> <address

Greetings, up until a year ago, I was running a server with Debian 10 (stable) on it with the latest versions of libvirt, qemu and kernel 4.19.x Debian 10 had to offer (both libvirt and qemu versions were really old). the network config was simple, one of the vm acted as a router and provided the ip for both the host and the vm. I've recently switched distro and now I'm running latest

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!

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

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

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

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

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 faced a couple of issues with libvirt update-device function: 1. http://libvirt.org/hvsupport.html says that virDomainUpdateDeviceFlags is supported since 0.8.0 API version in qemu driver. However when trying to update network device (changing source bridge of the interface) on Ubuntu with 0.9.8 libvirt version I get the following error: "*this function is not supported by the

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

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:

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

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
