CentOS 7 host with guests as bridge cannot access host
This is unfortunate.
https://wiki.libvirt.org/page/TroubleshootMacvtapHostFail
To the "normal" user - BRIDGE means guest is on the same network and has
access to the host.
Bummer.

CentOS 7 host with guests as bridge cannot access host
I have CentOS 7 host. Two guests on bridge network setup by GUI and
virt-manager.
1 CentOS 8 guest
1 Win 10 guest
Both cannot access the host. They can other machines on the network. Guests
can access the internet just not the host.
I used virt-manager GUi to set up everything. Selected the eth0:macvtap and
Bridge.
I "desire" bridge network.
If I select something else I get access to

Thanks I was using iptables and not converted to firewalld. I am doing so
now.
Will I need to delete the VM and re-add it ?
I am rebooting first.

OK I rebooted.
I changed the NIC from Bridge to Passthrough, hit apply, then changed it to
bridge and hit apply, then booted the VM.
My firewall looks better but still not working.

Dom0 cannot see network when bridge is enabled
I''ve seen a lot of threads w/ similar problems, but none have posted a
resolution.
I am using Debian 4.0r1 (Etch). I was using the xen packages from
stable, but have tried w/ testing as well and the problem persists.
http://pastie.caboo.se/95144
Host is 10.0.0.20 on network 10.0.0.0/24.
Dom0 is thus 10.0.0.20
DomU is 10.0.0.30
When the bridge is enabled, DomU can ping everything.

bridge network question
I have centos 64 6.5
I installed bridge-utils
I installed tunctl
I added BRIDGE=br0 to ifcfg-eth0
I created ifcfg-br0 with correct settings
I did service network restart
and I get an error about br0 not present.
When I plug in the second network (USB to ethernet)
It detects as eth1
What do I need to change to get this to work.
Thanks,

Anyone gotten qemu to operate in bride network mode on centos 4
I have been asking on the qemu list how to get bridge network mode
working under centos 4... To no avail.
The following script is what I have tried as my /etc/qemu-ifup. It
supposedly worked for fedora.
#!/bin/sh

# qemu_up

# script to bring up the tun device in QEMU in bridged mode

# This script bridges eth0 and tap0. First take eth0 down, then bring it up with IP 0.0.0.0

quick question on conf bridge
I have a customer that is using a quad core xeon server with 4 GIG ram
and Te210P card.
Currently this machine is being used for calling out to their own people
as well other programs being run.
anyway they wish to start using it for a 30 person conference bridge.
I presume this is no issue??? I am running centos 64 and asterisk 1.4.30

machine with 2 ethernet cards e1000 and forcedeth
I am using centos 5 x86_64 AMD64 X2 4200+. I am current on yum update.
My machine has two ethernet cards. e1000 (eth0) and forcedeth (eth1)
[root at fsdsigns2 ~]# more /etc/modprobe.conf
alias eth0 e1000

sometimes on boot the forcedeth driver thinks it is eth0:

ethernet bridge setup
I have a USB to ethernet device connected to CentOS 6.5 on my laptop.
I setup ifcfg-eth0 and added BRIDGE=br0 on eth0
did service network restart, all came up.
"seems" to be working.
However when I plug an ethernet device into the USB port that is wanting
DHCP
it is not getting an address.
Is there something I missed in the setup?
I was expecting the device connected to the USB to

The easiest way to set up bridged networking on CentOS 7 is:
??? virsh iface-bridge eth0 br0 --no-stp
This command will create a new bridge interface, br0.? The existing
interface, eth0, will be added to the bridge, and its current IP
configuration will be migrated to the new

If you are running NetworkManager (the default), it's not too hard.
