QEMU KVM - Network Bridge not working

English Virtualization
1

I have a windows Client on my open suse 12.3 system. Everything with the KVM seems to be working just fine except the networking. I am stumped with this issue as to why my KVM is failing get something other than a 169 IP.

Initially I thought my issue was libvirt and made the following changes however the windows7 VM is still failing to obtain a network connection.

Initial settings

virsh net-list --all

Name State Autostart Persistent

default inactive no yes

Corrected to be active and autostart

virsh net-list --all

Name State Autostart Persistent

default active yes yes

Connection settings for libvirt.

<bridge name=“virbr0”/>

In your “KVM Settings”

Change
<source bridge=‘br0’/>
To
<source bridge=‘virbr0’/>

HTH,

Thanks for the response but never was able to get it working. Ended up wiping the machine and doing a fresh install, VMs, spice are working correctly now.
