After I completed my CISSP certification I wanted a break from all the studying and do something nerdy that I’ve been meaning to do but never got around to it. For me, this was doing a full Linux From Scratch build.<\/p>\n\n\n\n

Back in the day I would just load up Linux on another machine to use as a host but since I now have my studio workstation at home with more cores than I know what to do with, I decided it might be a good idea to put it to work running some VMs.<\/p>\n\n\n\n

Most of the VM’s I’ve worked with have predominantly been Type II hypervisors (meaning they run off a host OS) and every once in a while I’ll get to build a virtualization server using a Type I hypervisor. For some strange reason I completely forgot that Microsoft’s Windows Server Hyper-V is actually available on Windows 10 and 11 Pro.<\/p>\n\n\n\n

With it being a Type I hypervisor, it meant that my VM’s don’t have the operating system overhead like a Type II normally would (read more performance), but more importantly, it also meant that if I wanted to run VMs in the background as a service, I totally could while I still use my workstation. Yeah, it’s probably not the best idea in a production environment but this is my house\/home lab.<\/p>\n\n\n\n

I’ll cover my LFS build in another post as I’d rather cover some issues I found while using a Linux guest OS under Windows Hyper-V.<\/p>\n\n\n\n

Yes I know I could have just used WSL2 but I really didn’t want to mess with my main system all that much, especially since I’d likely be building and destroying many installs as I’d be testing a bunch of distros I’d like to use as the host. Technically speaking I could have just used ANY distro and then update the packages accordingly but I’d rather not muck around with that just to get my LFS build started.<\/p>\n\n\n\n

For the most part, I ran into two common issues.<\/p>\n\n\n\n

  1. Some distros just won’t boot or just get stuck in a black screen forever.<\/li>
  2. When they did work, I couldn’t copy and paste from my host (My Windows box) into my guest (my virtualized Linux box).<\/li><\/ol>\n\n\n\n

    Issue 1: Getting Linux distros to work properly<\/strong><\/p>\n\n\n\n

    After looking at a few distros, I settled on the EndeavourOS pre-installation live environment as my host for my LFS build. However, for some strange reason I couldn’t get it to boot properly.<\/p>\n\n\n\n

    Found out after a bit of searching that this problem can be worked around by using the Quick Create feature under Hyper-V and unchecking “This virtual machine will run Windows”<\/em><\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    After doing that, EndeavourOS booted fine!<\/p>\n\n\n\n

    Now it’s great that I got it to work but the problem is my main SSD where Hyper-V likes to defaults to doesn’t have that much space and I’d like to have my VMs sitting on a larger secondary SSD I have sitting around and set other options that the quick create menu doesn’t give me (like limiting the size of my virtual hard disk).<\/p>\n\n\n\n

    So now that I know Hyper-V will work, I just gotta figure out how to configure it manually so I don’t have to use the Quick Create and it turns out all I needed to do was disable secure boot under the host settings<\/p>\n\n\n\n

    \"\"<\/figure>\n\n\n\n

    This issue also replicates itself while I was trying to install some other distros, so if you run into the same problem. See if Secure Boot is enabled.<\/p>\n\n\n\n

    Issue 2: Getting Copy\/Paste to work<\/strong><\/p>\n\n\n\n

    Yes I know I really should manually type everything but sometimes, I just want to copy and paste text\/urls\/commands from my browser in my host machine into my VM. When I was running Virtual Box, I was fully able to copy\/paste between host and guest no problem after I install the guest tools, but I couldn’t find any that I could use under Hyper-V and EndeavourOS.<\/p>\n\n\n\n

    Online searches didn’t bring up much other than making sure I have enhanced sessions turned on for both the Hyper-V server and the guest, which I already did but it just didn’t work for the life of me. Sure I could just use a browser from within the VM but I really didn’t feel like doing that.<\/p>\n\n\n\n

    Apparently the Ubuntu distros from the Hyper-V Quick Create menus have guest tools built into the distro but I couldn’t get it to work either.<\/p>\n\n\n\n

    The only solution that worked was using xrdp and instead of connecting through the Hyper-V manager (effectively running VMConnect), I’d have to run RDP and remote in.<\/p>\n\n\n\n

    Thankfully I found a script that sorts all that out for me. I couldn’t get it to work under EndeavourOS but it did work fine under Ubuntu (and it supposedly supports Debian as well). <\/p>\n\n\n\n

    xRDP \u2013 Easy install xRDP on Ubuntu 18.04,20.04,21.04,21.10 (Script Version 1.3) \u2013 Griffon’s IT Library (c-nergy.be)<\/a><\/p>\n\n\n\n

    Following the instructions, the installation was pretty painless.<\/p>\n\n\n\n
