Solved CentOS 7 - no NIC in Hyper-V gen 1 VM
-
Just tried the Pandora FMS 7 ISO, which is based on the default CentOS 7 ISO.
I don't have a virtual NIC, looks like a driver issue. Couldn't find something with Google.
Anything obvious I just can't see?
dmsgdoesn't say much. -
You need to shut the VM down, and edit it. Add a new Legacy Nic -- those are limited to 100 Mbit.

Would be a fallback, already thought about it.
Should be ok for my use case, but not in a production deployment. Would rather like to solve this one right from the beginning.

Now you're going to make me go take a look at our install. I know Fedora 26 and 27 just work. I bet CentOS needs the guest drivers installed.

Uhm. I assumed they are. Erm... You make me look stupid

CentOS 7 can be installed using Generation 2 unless Pandora FMS is a strip-down version of CentOS 7.

Why not spin up Pandora on Fedora 26 or so?

https://docs.microsoft.com/en-us/windows-server/virtualization/hyper-v/supported-centos-and-red-hat-enterprise-linux-virtual-machines-on-hyper-v#BKMK_7xI couldn't even boot as gen 2 (with secure boot disabled). Something I did countless times with Debian based distros.

Because I just want to try it a bit and the v7 docker container seems to be broken on the MySQL side. They offer an ISO, so why not use it

Sound like you will need to install Linux Integration Services.

https://www.microsoft.com/en-us/download/details.aspx?id=55106awesome.. ok, thanks, will try that. Didn't even thought about this, because it's available in the stock Ubuntu ISO which is what I normally use.

Technically, you can install the tools that's available in CentOS but it will be an very old version.

Just tried it, and yes, missing integration services.
Long story short: I'll stick with Ubuntu
Yeah, I know, I could easily install them, but I'm more in the Debian corner anyway.
