similar to: vnetX interface name persistence

Reposting from virt-tools mailing list: Hi! I'm facing a problem that could be triggered by some lacking of support from libvirt on Open vSwitch (or could be my mistake). I have interests in researching on virtual networks and SDN. To keep things simple, I've decided to use libvirt/virt-tools to manage VM's since my focus is on the network, instead of using a full feature system

Hi all, I have a two-node HA RHEL 6 setup hosting VMs. These use static/standard bridges and all has worked wonderfully. Now though, I need to adjust the qlen value of the vnetX devices for a given guest VM, which I can do with: ip link set dev vnet0 qlen 6000 The problem with this approach is two-fold though; 1. I need to determine which vnetX is connected to a VM. 2. If the VM

Hello! Since i could not find any information on the internet about this subject, i'm going to try my luck on this list. I'm trying to setup network-filter on a routed setup. I have a root-server at Hetzner, a german hosting provider. Along with my server i ordered a (/28) subnet to be able to setup dedicated IPs for my virtual machines (KVM). My Server is running Ubuntu 12.04 with

Hi All: I'm facing a weird behavior with Samba 3.5.10. It's a CentOS 6.3 repository RPM. Samba is acting as a PDC and integrated with OpenLDAP 2.4.23, also a CentOS RPM, through smbldap-tools 0.9.3 (from EPEL). In my network I have Windows 7 64 bits and Windows 7 32 bits. The problem is that Samba is losing local master browser 'status' to Win7 32 bits machines. From time to

Hi all, How can I see what vnet is attached to a certain kvm guest?? For example: I have a kvmguest1. When I launch this guest with virsh command, virsh creates a new vnetX interface for this guest. How can I extract this virtual net interface (vnet0, vnet1, vnet2 or so on) using a script?? Thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Currently, I have two networks configured via xml: virsh # net-dumpxml TestNetwork1 <network connections='2'> <name>TestNetwork1</name> <uuid>a76f665a-0196-4edb-81b4-340944a6869c</uuid> <forward dev='p1p1' mode='nat'> <nat> <port start='1024' end='65535'/> </nat> <interface

Thank you, Laine for you time and patience to give me a detailed answer. I missed the interfaceid parameter in the docs, but now I didn't manage to get it working. > http://www.libvirt.org/formatdomain.html The docs state: "The Open vSwitch type virtualport accepts two parameters in its <parameters> element - an interfaceid which is a standard uuid used to uniquely identify

Hi I'm trying to monitor bandwidth usage of a KVM VM but couldn't find <target dev='vnet0'/> on virsh edit domain_name all i get is this <interface type='network'> <mac address='52:54:00:a1:05:b6'/> <source network='vmango'/> <model type='virtio'/> <address type='pci'

hi, I stop libvirsh and I see it removes vnetx interfaces, but those(at least) of bridge type remain in the system after daemon is stopped. Is this intended would you know? thanks, L.

Hi All, First time mailing here. I have installed on a CentOS 7.0 KVM (with DPDK and OVS) one Deep Packet Inspection VM. I have one channel and some virtual traffic generator. The traffic is lost between dpdk vhostuser and the DPI VM. The setup is attached. Any suggestions or ideas? Regarding the OVS+DPDK configuration, the following configuration is already made: - SELINUX is disabled - QEMU

But to be honest i tried to avoid upgrading and compiling a newer version since i don't know if it has any effects on running VMs (but i haven't checked this yet). Its a production server and i did not want to interrupt any services running on

I'm dealing with an old Xen 3 server, and badly need to update it and all the vm's on it to more contemporary operating systems. So far, so good! Can the Xen server on CentOS 5 para-virtualized CentOS 6? And if not, I'm having real trouble getting a live cd or installation media to boot in full virtualization to do the update of the guests. I'd normally start by updating the Xen

Hello I have a virtual server with 3 existing VMs running on it without issue. The host has 4 NICs installed; em1 for the host, em2 and em3 already in use by other VMs. I would like to dedicate em4 to my new VM however when I create the bridge like I did for the others I do not get a vnet3 device show up in the list as shown below. I tried using the GUI and virsh to create the bridge. I ended

Can i assign static vnet* device for some guests?
