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

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

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.

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

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

Hi, ran into a problem w/ linode hosted VM where IPv6 address changed after they migrated it to a different host. They claim I can fix it with sed -i 's/slaac private/slaac hwaddr/' /etc/dhcpcd.conf However there appears to be no dhcpcd.conf on any of my CentOS 7 systems. What is the CentOS 7 equivalent?

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'>

I have a second server and gave it a WAN address and I can connect between them using their WAN addresses. That's what told me that my ip6tables weren't screwed up and that the problem lay elsewhere.

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

I am running Fedora 16 64bit and installed libvirt. I have the VM running with arm emulation with this one issue I can't figure out. I used Virtual Machine Manager to manage the VM and can access its console there. The Ethernet appears to be eth1 and the guest can set an IP on it etc. However, I cannot see any traffic from the Host when dumping any of the interfaces. I've tried

Hello, Firstly THANK YOU for the IPv6 NAT support merged in 6.5. It has been almost impossible to get IPv6 into a VM on a laptop that switches between wifi and wired (dock) connections, because you can not add a wifi interface to a bridge. I know NAT is against the IPv6 end-to-end xen but it makes this "just work" for the vast majority of people like me who need to ssh/curl/talk to

Hi Ashish, IMO, it is yes, no way to increase tx_queue_size for direct type interface ------- Best Regards, Yalan Zhang IRC: yalzhang Internal phone: 8389413 On Thu, Oct 26, 2017 at 3:38 PM, Ashish Kurian <ashishbnv@gmail.com> wrote: > Hi Yalan, > > In the previous email you mentioned "tx_queue_size='512' will not work in > the guest with direct type

We've started having a problem with a CentOS 7 server. It looses its IPv6 address, if I understand this issue correctly. We can get in, if we do ssh -4, though. In the logs, I'm seeing this about twice an hour: <warn> (pid 98466) unhandled DHCP event for interface ens3f0 Now, in googling, I get very few hits putting quotes around "unhanded dhcp exception" - in fact, the
