Hi! I'm aware that (host side) vnetX are created when VM boots. But I'm trying to figure out a way ti create a persistence in vnetX names. What I mean is, say, I want to associate VMs vm0 to vnet0, vm1 to vnet1, vm2 to vnet2 and so forth, no matter which order the VMs are booted. I looked around network XML format, but did't find something... Since I'm using Open vSwitch as

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, 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

Can i assign static vnet* device for some guests?

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

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

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

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

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
