Installed Debian 9 (twice even) on this server. Was pinging fine during installation via KVM on IP xxx.xxx.98.106 (main IP). After reboot, nothing is coming up on eno1 interface. Any ideas?
Well, it's not the same error, now the system sees the interface, it just can't bring it up ... read here https://www.redhat.com/sysadmin/static-dynamic-ip-1 hopefully there's something there that can help you solve your issue.
If it is installed use ethtool first on each of the interfaces to see which one has an active link and then configure that interface with the ip configuration in /etc/network/interfaces, so something like this.
Code:
ethtool eno1
Then check if it says yes where it says "Link Detected"
Once you find the one that has link create an ip configuration for it, that would something like you had before.
No quite the same error, now it's telling some firmware it's missing. How did you create the VM? virt-install? qemu? Can you show the VM's settings? I wonder if there's something missing from the settings you used when creating the VM.
