Dear all I have the following problem: -I'm running libvirt 0.9.11 on ubuntu 12.04; -when I try to create a VM with the following configuration: ... <serial type='pty'> <source path='/dev/pts/2'/> <target port='0'/> <alias name='serial0'/> </serial> <console type='pty' tty='/dev/pts/2'>

I was looking at the release candidate of libvirt (0.9.11-rc2) and I have not been able to understand if the openvswitch support includes the port tagging support. So my question is: is it possible to create a tagged port? How? Otherwise, would it be useful to add this functionality?

Hi. I have a machine with a local DHCP server and a couple of virtual networks and I've configured the server for each virtual interface, so that I would be able to install VMs on the corresponding subnets using PXE. The problem is that the two DHCP servers (my local server and dnsmasq) are conflicting with each other causing the boot process to either fails or takes ages untill a VM can

Hi everyone. Those are the iptables forwarding rules associated with the two virtual networks on my machine: ----------------------------------------------------------------------------------------- -A FORWARD -d 192.168.100.0/24 -o virbr1 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -s 192.168.100.0/24 -i virbr1 -j ACCEPT -A FORWARD -i virbr1 -o virbr1 -j ACCEPT -A FORWARD -o

Hello, I came across an interesting problem in my home lab a few weeks ago as I'm prepping for my RHCE exam using Michael Jang study guide. I've been at this for days now, and I still can't wrap my head around how two or more virtual networks in default NAT configuration are even allowed to communicate with each other despite what the libvirt documentation said. Here's the

Hi all, When I defined a network use the host bridge "virbr1" an error occurred : "libvir: error : Unable to create bridge virbr1: File exists" But how can I define this network use the host bridge "virbr1" ? <network> <name>def1</name> <bridge name='virbr1'/> <forward mode='nat'> <interface dev='eth0'/>

Hello, I have first a question (and then may be a problem), that I have difficulties to understand and eventually to investigate. On each of my guests VM, I see constantly a RX dropped number increasing , Even if the VM does nothing ! ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.100.15 netmask 255.255.255.0 broadcast 192.168.100.255

Hi all, I have 3 guests (2-RHEL4 and 1 RHEL6) and have some issues regarding networking between them. The 2 RHEL4 system's use default bridge virbr0 and get ip's of range 192.168.122.0/24 (192.168.122.207, 192.168.122.167) I created another bridge (virbr1) with NAT forwarding (no dhcp). The network i choose was 192.168.100.0/24. And the third system (RHEL6) was assigned static ip-addres

Thanks, Mike. When running tcpdump on the VM I'm not seeing traffic unless it's explicitly intended for that particular VM, so no traffic between the other VMs is getting forwarded from the virtual interface to the "network appliance" VM. There is connectivity between the VMs on the private network and the "network appliance" VM which is acting as a gateway.

Hi Mike, Thanks for the info. I'd rather run monitoring such as tcpdump from the VM if possible and not the host as a simulation of a network appliance and with the intent eventually of giving others access to the VM and not the host. Here is the xml file for the private network: <!-- WARNING: THIS IS AN AUTO-GENERATED FILE. CHANGES TO IT ARE LIKELY TO BE OVERWRITTEN AND LOST. Changes to

Hi all, I try to understand why the network bandwidth limits are not applied to my ubuntu 16.04.2 VM (qemu-kvm driver) and I would need some insights. I create my VM network with virsh and when I issue a dumpxml on my network, I can see that bandwidth limits are set: virsh # net-dumpxml nat_limit <network> <name>nat_limit</name>

Actually, I know what the MAC is for the builtin Port1 and 2. Those are listed in the BIOS. But ultimately I don't want to rely on them as I want the same kickstart file to work for other machines, so hardcoding those in the kickstart file wouldn't quite work, unless I start writing multiple kickstart files, one per machine. Anyway, lspci reports this: 00:19.0 Ethernet controller: Intel

Hello all! I try to use network filters for openvswitch interfaces.  This is the xml configuration of my bridge interface <interface type='bridge'>    <mac address='00:11:22:33:44:55'/>    <source bridge='virbr1'/>    <virtualport type='openvswitch'>         <parameters interfaceid='0529d6b5-627c-4330-803f-0d7018e6d496'/>   

Right, I understand that part. However I believe I'm now in the realm of making this specific to this machine as I have no guarantee that another identical machine will pop up with those same bus IDs. Maybe for the internal ports, but I don't know if the same will happen for the PCIe bus. Would that be correct? On Thu, May 14, 2015 at 6:21 PM, Kahlil Hodgson < kahlil.hodgson at

When I was working on this last time (with the r8169 driver), someone on this list provided the following script which is what "fixed" the issue at the time by creating a new 70-persistent-net.rules file with the devices enumerated in order. However, this no longer works now. echo "[KICKSTART] Binding eth interfaces to the expected MAC address in UDEV" echo "## Created by
