reminds me of https://bugzilla.redhat.com/show_bug.cgi?id=1308420 Well, general rule of thumb: 1. do not rename in the "eth*" namespace 2. if you do, you have to specify every interface, which will appear 3. don't forget to generate ifcfg-* files with HWADDR for every interface, which will appear 4. see 1. In essence: use "net[0-9]" and you will have no "rename*" problems Created attachment 1131815 [details]

(In reply to Fani Orestiadou from comment #13) > Created attachment 1131816 [details] > traces level "debug" /etc/udev/udev.conf not very helpful In the error case, what is the output of: # cd /sys/class/net # for i in *; do biosdevname -i "$i";done Created attachment 1143842 [details]

By my reading of the comments here and the case, we have narrowed down the issue to a problem in biosdevname, but we require additional input from the customer's reproduction of this issue in order to properly diagnose it. The customer case has been closed due to inactivity, so we are not expecting any forthcoming details. As such, I am closing this bug. If there are any customers actively experiencing this issue, you may reopen the bug report with details. |
