AW: debian 10, vm cant connect to the host bridge
I should have what i want to achive.
The server is intended as a host for VMs. Our network has multiple VLANs, and the VMs will be connected to different VLANS. The interface eno1 is for host traffic and eno2 is connected to the trunk port of the switch, making the different VLANS availabel to the VMs via the br0. I want to use a VLAN-aware br0, so that I specify in my VM config (on the host

someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work.
Here is my current host interface config:

Small bug when server IP changes
I think this is a bug:
CentOS 5.4 using Samba 3.4.7.  If the server IP address changes, nmbd
complains every few minutes that "There is already a domain master
browser" on the old IP address.
Although "Chapter 41. Managing TDB Files" states:
wins.dat N WINS database iused only when wins support = yes has been
set. This gets rebuilt or updated at every restart.

network-bridge called three times
Hello All,
I'm trying to figure out why xen-utils-common 3.2 doesn't suport
bridging on multiple interfaces. I've been digging
around /etc/xen/scripts/network-bridges. And modified it so that during
boot, when executed the script writes into /tmp/netbr file, but I
commented out code that actually creates bridges.
I discovered that this script is called three times during boot, I

Hi,
Can you show as the config of eno4?
And can you diff the config of eno1 and eno4. Looks like there is a
difference somewhere.

network-bridge fails to copy from eth0
I''ve just installed Xen on a new CentOS 5.1 system, and I can''t seem  
to make xenbr0 connect to the network.  This system has a single  
physical network card.  Apart from creating a few DomU guests, I have  
not changed any of the configuration.
After running network-bridge, xenbr0 and friends are created, but the  
address and routing info is not moved.

macvtap and tagged VLANs to the VM
Hi,
I would like to run a network firewall as a VM on a KVM host. There are
~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP

200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0.

No DHCP on default network when guest has multiple interfaces
Hello,
I am trying to boot a VM in libvirt that has 2 interfaces. The first
interface is connected to the default network and the second connects to a
bridge interface on the host. When the VM boots the first interface doesn't
receive an IP address from DHCP. It works when the VM only has one
interface though.
If I login to the VM using virsh console I noticed that in NetworkManager
