Hi, my virtual machine is being moved from old to new host. It turned out we cannot predict new interface names. If I boot up on the new hypervisor with net.ifnames=0 the following trick does not give me the future interface name (or at least, it seems to be unchanged): # udevadm test /sys/class/net/eth0 2>/dev/null |grep ID_NET_NAME_ ID_NET_NAME_MAC=enx525400d73a09 ID_NET_NAME_PATH=enp0s3 # From rc.log I see only: rc default logging started at Sun Apr 7 04:04:37 2019 * Bringing up interface enp0s3 * Caching network module dependencies * ERROR: interface enp0s3 does not exist * Ensure that you have loaded the correct kernel module for your hardware * ERROR: net.enp0s3 failed to start * Bringing up interface eth0 * xx.xx.xx.xx/24 ... [ ok ] * xxxx::1/48 ... [ ok ] * Adding routes * default via xx.xx.xx.xx ... [ ok ] [ ok ] * default via xxxx::fe ... [ ok ] [ ok ] * Waiting for IPv6 addresses (5 seconds) . [ ok ] What am I asking for: 1. openrc could try to use `biosdevname -i eth0` if installed and include that in console output, which I can read on VNC console and even later in /var/log/rc.log. 2. openrc could just list all `ifconfig -a` interfaces 3. arguably it could pick the wired eth interfaces if there is only a single choice. I anyway keep settings for net.eth0 and for net.enp3s0 in /etc/conf.d/net (setting smae IP addresses for both, supposedly eiother one will be picked up), have modified /etc/rc.conf to 'rc_depend_strict="NO"' so that whichever network interface comes up will allow additonal services to be started (like sshd). I ran "rc-update add net.eth0 default" and "rc-update add net.enp3s0 default". # emerge -pv openrc These are the packages that would be merged, in order: Calculating dependencies... done!
