Hello, I have a setup of virtual machines and wherein my virtual switch (OVS) takes care of switching locally and it uses the network for talking to VM's outside the server (like a VEB scenario I guess). I want Netlink messages to be sent to LLDPAD. I understand that i had to modify the XML files and start the VM. But, i see from the XML that it supports only VEPA, not VEB. But, irrespective

Hello all, I'm trying to take advantage of libvirt's VLAN and OVS support in the 0.10.1 release and consistently getting an "error: internal error corrupted profileid string" when starting a guest. I've defined a network using virsh; the configuration looks like this: <network> <name>ovs-network</name>

Hi, I have created a libvirt network on top of a OVS bridge (named vlan-br) which receives all VLAN tagged packets, i.e. connected to a trunk port. The definition xml is below. What I want to achieve in the portgroup definition 'trunk-native-1221' is to allow 1221 as untagged/native but rest all VLAN as tagged. The following portgroup definition works, but I don't want to enumerate

Hi, my system got updated to libvirt 6.0.0 (from 5.6.0) this morning, and now I'm having problems starting VMs that make use of openvswitch portgroups. When I start a VM, I get this error message on virsh: > virsh # start testvm > error: Failed to start domain testvm > error: An error occurred, but the cause is unknown The system log contains: > Mar 30 09:45:39 tplinux

Hi, I tried to create a VM in ESXi 5.5 and to assign the interface to a Distributed switch portgroup. But i failed to achieve it. When i define a VM with distributed portgroup , i cannot see that distributed portgroup getting assigned to the VM network interface. My libvirt version is 0.10.2 I wish to know whether the libvirt supports assigning interface to a distributed port group ? If so how

hi everyone, I'm trying to get vlans tagged in libvirt as my switch's end (yes traffic will be leaving the host and into network switches) allows only tagged vlans. But with network as such: ...   <portgroup name='vlan-55'>     <vlan trunk='yes'>       <tag id='55'/>     </vlan>   </portgroup> </network> and guest as:

Hi, I have an ESXi server, on top of it I have created one VM whose IP address is 192.168.79.1. I want to connect to the VM on ESXi server from my host machine but I am not able to do it. I have created a network "networkforSC" and I have pasted my xml file content below but I am not able to add any uplink (how to add it?) . Below is the xml file of my node as well as the network which

Thank you, Laine for you time and patience to give me a detailed answer.

Paul, if you can set up a VLAN on your network infrastructure between the two hosts, I'll share the recipe I use with Open VSwitch. We trunk a VLAN between our hosts for sandboxed guests, setting up a OVS bridge on each host that handles guests but also has a connection onto the VLAN. Are you using any configuration tool? I've got this in Puppet but should be able to convert to a shell

Thanks Laine, I will take a look at Open vSwitch, it looks interesting. I am a generalist, I need to know enough about a lot of things to get many different tasks done, but do not have the in depth knowledge required to "patch" anything.  If I manage to wrangle a working solution should I post it? Needless to say I would be supportive of said feature being implemented by those

Hi all, How do you add a VLAN tag to a libvirt SR-IOV VF network usingthe "virsh net-update" command? I couldn't find the section to passto the "virsh net-update" command to add the VLAN tag. I have the following libvirt network defined for a SR-IOV VF: <network>  <name>GE0-0-SRIOV-1</name>  <uuid>7bc67166-c78e-4bcf-89ee-377dd9086631</uuid> 

Dear Michal: I'm sorry. The pasting XML I described earlier is wrong, and the real thing is: <interface type='bridge'> <mac address='52:54:00:0a:2b:2a'/> <source bridge='lcs_br_1'/> <virtualport type='openvswitch'/> <bandwidth> <inbound average='0' peak='0'/>
