similar to: how to restart the network connection of kvm guest OS ?

I am running KVM guests under Redhat 6. I tried to setup a bridge device to an interface with a vlan trunk connected to a Juniper switch. On the KVM host, I am able to define vlans and access them via the vlan trunk. I was not able to access a vlan from the kvm guest connected to the bridged interface. I believe this would be what is commonly called QinQ or 802.1ad. Is this possible to do? I

hello all, I have been trying to set-up bridged network with VLAN and not able to succeed as many tutorials address only single NIC.

I was wondering if there is any way from either the virsh CLI or the libvirt API (preferably virsh) to get the amount of disk space to get the amount of disk space each guest has been assigned?? -------------- next part -------------- An HTML attachment was scrubbed...

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> 

Hello all, I have a machine running Centos 6.6 connected to a port on a Cisco Catalyst 3750 series switch. That port is part of VLAN 48. I have VLAN 48 on the CentOS machine too. The IP network on VLAN 48 is 192.168.48.0/255.255.255.0. The address on the CentOS side is 192.168.48.101, the address on the Linux end ought to be 192.168.48.100. When I only bring up eth0.48 VLAN device with the

Im configuring my KVM and in my network configuration I have 4 Network lancard 2 nic = using teaming0 for management with access port configured in the switch side 2 nic = using teaming1 for guest VM DATA ports. and in the switch is configured for LACP with trunk allowing vlan 10,20,30,40,50 and configured in the CentOS7 the vlan 10, vlan 20,30,40,50 im sure its already working because I tried

Hello I have a problem with attaching VMs to a VLAN interface. Here is my setup: I have several physical hosts connected by a physical switch.  Each host has two NICs leading to the switch, which have been combined into a team, team0. Each host a has a bridge br1, which has team0 as a slave. So communication between hosts is based on the IP address of bridge br1 on each host. Up until

Dear list, I have moved my HVMs from xen to kvm and it worked well except some problems using virsh. First, one OpenSolaris HVM does boot with warnings: WARNING: /pci at 0,0/pci1af4,1100 at 1,2 (uhci1): No SOF interrupts have been received, this USB UHCI host controller is unusable* *The corresponding process: /usr/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 1024 -smp

I have run into a problem attempting to attach the seventh virtio-scsi device to a RHEL 6.4 Guest from a RHEL 6.4 host running libvirt version 0.10.2-18. I have a guest that is running RHEL6.4 where I can attach disks sda(boot), sdb, sdc, sdd, sde and sdf but when I try to attach sdg the virsh attach-disk command fails with the error: error: Failed to attach disk error: internal error Unable to

Hi list, I'm using OVS as backend for guest networking on my hypervisors. VLAN configuration for each interface is specified into the guest XML definition. When I need to change VLAN configuration of a running guest, I first edit the inactive XML to keep the changes for future boots, then I use ovs-vsctl to instruct the changes on the existing OVS Port. The problem happen when the guest is

I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4. Hi Hongming, I'm hoping you can please help with two issues: 1. The pool works, but I transparent VLAN with the pool does not. I have to manually run "ip" afterwards to get it to work. # virsh net-dumpxml em2net <network connections='1'> <name>em2net</name>

Hi guys, I hope you can help me on this issue with kvm/libvirt: using this command to install a kvm virtual machine: virt-install --connect qemu:///system \ --name p3k0401 \ --ram 2048 \ --file //dev/VolGroup01/p3k0401logvol \ --accelerate \ -s 10 \ --nographics \ --hvm \ --location='http://10.1.4.80' I get: Starting install...

Okay, just installed libvirt from today's git on two Ubuntu systems. The first one went fine (except for continuation of the problem that virsh and virt-manager cannot connect to 0.8.3 systems that's been there in the 0.9.x libvirts) ... but on the second, after install, "virsh list --all" presents nothing. And: # virsh define tu1004.xml error: Failed to define domain from

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, virt guys, This is Hongqing from Fedroa QA team. I try to forward the guest installation logs to host with virtio. I have used virsh edit <guestName> to add a channel, it works fine. I think it would be better if I can initialize it when I create the guest using virt-install, and virt-install also offers the option, I have tried below, but it does not work. virt-install
