I am completely new to Hyper V and NetRunner. I have Hyper V running and I downloaded Debian-based Netrunner Desktop 19.01 64-bit ISO.
In Hyper V I click new virtual machine
I selected Generation 1
Set startup memory to 2048 and left Use dynamic mem checked
Set networking to Default Switch
Selected the ISO
Click Finished
Virtual machine is created.
I start it and select: Start Netrunner Desktop Live (amd64)
I see message: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr
After a short bit, I end up at live@live-pc:~$ prompt
So it seems to boot correctly but is not able to start the graphical user interface.
You could on this prompt check with your favorite text editor why Xorg is not starting by taking a look into the file /var/log/Xorg.0.log.
Look for lines arround the (E) symbol which indicates error. Or paste the whole file somewhere if possible.
