I have a laptop upon which I run Xen with Fedora 24 serving as
Dom0. Something is causing the creation of my DomU domains to fail. It
seems that after I create my first DomU, something places a file of the
form ifcfg-vifX.0 in /etc/sysconfig/network-scripts/. Once this file
exists, subsequent DomUs seem to cause Xen to create an interface named
vifX.0, even though Xen passes vif=vif(X+1).0 to the vif-route script.
I suspect this has something to do with NetworkManager.
I do not yet understand Xen's network initialization process well enough
to understand what is going on. However, removing
/etc/sysconfig/network-scripts/*vif* seems to fix the problem (until
after I create the next DomU).
Has anyone else seen behavior like this? Does anyone know what is likely
I would like to continue to run NetworkManager.
