I have a host setup for libvirt kvm/qemu vms. And I wonder a bit about the overhead of the macvtap and how to configure the mtu's properly. To be able to communicate with the host, I have moved the ip address of the host from the adapter to a macvtap to allow host communication. I have the below setup on hosts.

The guest was setup through virt-manager. The machine is not configured much after a F20 install (I believe I didn't change any network things) Here is the network part: <interface type='direct'> <mac address='52:54:00:fe:b0:66'/> <source dev='em1' mode='bridge'/> <target dev='macvtap0'/> <model

Hello I have realized a problem with incomming multicast packages to a VM. My Setup is: 1 Host with 1 VM. On the external Network (Host: eth0), there ist a Multicast Stream. The packages are visible at the hosts eth0. The Guest is connected via macvtap to the eth0 from the Host. Host and Guest ist CentOS 7.6 in Future it should be RedHat 7.6. The guest is connected via macvtap0 to eth0. If i

Greetings all, I have a host machine that runs a router within a vm. I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm. I've created a dummy interface with these commands: $ ip link add ens99-dummy type dummy $ ip link set ens99-dummy address 52:54:00:1f:d0:ff this resulted with this output: $ ifconfig ens99-dummy

Okay, so I''m trying to setup my multiple ISP setup that I described earlier. I have: # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP>

Since RHV 3.6.10, the default network name is 'ovirtmgmt' instead of 'rhvm'.

Hello @ all With the rebuilding of my Server from Debian 9 to Debian 10, I also switch from Virtual Box to Libvirt/KVM. Due to new requirements for the VMs, now I have an actual problem, which unfortunately I can not solve. The problem has already been discussed in the German Debian-Forum ... unfortunately also without success. The facts: - ISP = Dual Stack with daily separation - Host and

When parsing OVA files we have to work backwards to whether the original VMware object was a network or a bridge. It seems as if the presence of <rasd:Connection> is sufficient. I dropped the use of <rasd:ElementName> since it is literally just an internal name for the network element, and is not significant in how the network is used. Also update documentation because you must use

Hi, I'm using libvirt and qemu on Debian Wheezy. I'm having a strange behavior. Guests can't connect to each other when they're on the same host. On the host I'm using bonding (in active / backup mode) and vlan. It looks like this : eth0 \ / macvtap0 bond0 --- vlan222 eth1 / \ macvtap1 So I've got two guests, let's say A and B. When

Hello, I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT. When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the

Hi, I'm just migrating some stuff from Slackware Linux to CentOS, and I have a question about the orthodox way of configuring a network connection. On a desktop or workstation, I usually get rid of NetworkManager: # systemctl stop NetworkManager # yum remove NetworkManager Then I edit the /etc/sysconfig/network-scripts/ifcfg-XXXXX file corresponding to my network interface. Here's

Hi Niki, On CentOS it's normal for both wireless and wired to be connected at the same time, maybe what you are seeing is just the icon's being confusing or not being replaced with the right thing? This is easy to check, just issue an "ip route". On My system I can see something like this: default via 192.168.0.1 dev eth0 proto static 192.168.0.0/24 dev eth0 proto kernel

Hi Yalan, In the previous email you mentioned "tx_queue_size='512' will not work in the guest with direct type interface, in fact, no matter what you set, it will not work and guest will get the default '256'. " So if I am using macvtap for my interfaces, then the device type will always be direct type. Does it mean that there is no way I can increase the buffer size

OK, I have a strange problem. It is probably something simple/stupid, but I cannot figure it out. I have a nice new PowerEdge T20 that I installed CentOS 6 (6.5) on with Virtualization (KVM). I then installed Ubuntu 14.04 in a virtual machine, with a bridged network: ------ begin ub140464.xml------------------ <domain type='kvm' id='2'>

Hi Yalan and Michal, Thank you for your response. So what I understand is that I can change rx_queue size even if I use direct type interface and qemu driver as long as the driver is virtio. Am I right? If that is the case why am I getting the error saying that error: XML document failed to validate against schema: Unable to validate doc against /usr/share/libvirt/schemas/domain.rng Extra
