I was looking that NM applet and cli show virbr0 bridge, but when i setup bridge in the VM guest, and play run, this error appear:
internal error: /usr/lib/qemu/qemu-bridge-helper --use-vnet --br=virbr0 --fd=31: failed to communicate with bridge helper: Transport endpoint is not connected
stderr=failed to parse default acl file `/etc/qemu/bridge.conf’
And the file is not, i google it and found that is a bug fixed in arch in 2015: FS#46791 : [qemu] Missing /etc/qemu and bridge.conf.sample
And according with the guide, I will be create /etc/qemu/bridge.conf but /etc/qemu dir does not exists
So, is a bug really or the new version does not have example config? i am using unstable branch.

EDIT: I can obtain network using virbr0 in user mode network but not other mode (iptables etc) but anyway, the package does not create /etc/qemu/bridge.conf and the example file. I dont know where report bugs.
