Hi,
I'm trying to control the name of the 'tap0' device that gets created as I start a domain that uses bridged networking. The XML specification of the domain contains the following configuration
<interface type='bridge'>
<source bridge='br0'/>
</interface>
The libvirt documentation (http://libvirt.org/formatdomain.html#elementsNICSBridge) and other discussions online tell me that I just need to include the <target dev='desired_dev_name'/> tag in the XML specification of the domain under the <interface> tag. Unfortunately doing so appears to have no effect; the tun device created and 'enslaved' in the bridge is still called 'tap0'. Interestingly, I never get a tun device with a name prefixed by 'vnet' or 'vif' which, according to the documentation, is the default behaviour (?). The host is running CentOS 7, and virsh is used to start the domain.
Best,
Govert
