Re: [libvirt-users] sttic vnet device for guest

vnet* devices are created by libvirt when a domain is being started (or on device hotplug). In general, unless all devices would be statically allocated, it would be impossible to guarantee certain vnet name.

However, what you can do is to create the device yourself and then just tell libvirt to use it:

<interface type='bridge'> <source bridge='vnetX'/> </interface>

I think that libvirt will just dismiss the interface because of its prefix and creates another one itself. It would work with another prefix. -- Make sure your code "does nothing" gracefully. - The Elements of Programming Style (Kernighan & Plauger)
