Development and testing on HiveOS in a VM

Hi, I have a mining rig setup with 5 GPUs and I want to do some testing on it with a custom miner, but I don’t want to have it stop mining while I am testing things. I thought I’d try to install HiveOS in a VM on my non-mining PC for testing out things before I do it for real on the rig so that in case something doesn’t work how I expected then I don’t lose out any mining time.

I was able to install the OS in VirtualBox without any issues, and I wanted to install the guest additions, but it appears that Hive is running a custom kernel and I can’t find the kernel headers to compile the guest additions kernel module against.

Could you please add support for building 3rd party kernel modules like the guest additions against the HiveOS kernel?

Somehow I missed the headers in /usr/src/linux-headers-5.10.0-hiveos.

Ok compiled the guest additions without issues but the kernel module doesn’t load due to some missing symbols.

I run rcvboxadd setup and the below is the output:

So I check dmesg:

Anyone have any ideas?
