similar to: Qemu guest(s) in bridge mode cannot see host machine.

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. Jerry

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

>Sorry, have to correct myself. Had to much to do today on OpenShift. >There is no Docker involved in what we discuss. The firewall rules for >the host bridge devices get created by libvirtd. 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. Jerry

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. iptables -L FORWARD -v -n | egrep '(policy|virbr1)' Chain FORWARD (policy ACCEPT 0 packets, 0 bytes) 0 0 ACCEPT all -- eth0 virbr1 0.0.0.0/0 192.168.100.0/24 ctstate RELATED,ESTABLISHED

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.

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, jerry

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 # /sbin/ifdown

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 I was thinking they might need to expand the card to a

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

I have try to install from iso Windows 10 on a centos 6 + qemu/kvm, but the guest not start and reboot after a while. Form this page: http://www.linux-kvm.org/page/Guest_Support_Status#Guest_Support_Status?

Hi all, let me see if I can explain my problem in an explicable way. I have written a WLAN driver which runs on a dedicated box (e.g. not a PCMCIA card). The box is plugged into a client that wants WLAN connectivity via Ethernet. E.g.: [ ] Ethernet [ ] RF/WLAN [ Laptop ]------------------[ WLAN adapter ]------------- [ ] [ ]

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
