Issue with qemu working properly in Ubuntu. #3
Description
This is in regards to the 2nd or newer YouTube video series on OS Development Episode 1.
Since I'm still running Windows 7 x64 as my Host operating system I'm not able to use wsl. So I opted to install Ubuntu in Virtual Box. Now, before I installed Ubuntu's latest distribution from its ISO file, I configured Virtual Box to be in EFI mode before installation. After installing Ubuntu, I updated and upgraded it, and I also installed a few other useful utilities before proceeding with this tutorial... One of them was Virtual Box's Guess add-ons... After that, I installed git, and curl just to make sure they were either on the system or up to date.
While I was following the video, everything worked fine until I tried doing:
make run
I get this error:
qemu-system-x86_64 -drive file=bin/CustomOS.img -m 256M -cpu qemu64 -drive if=pflash,
format=raw,unit=0,file="../OVMFbin/OVMF_CODE-pure-efi.fd",readonly=on -drive if=pflash,
format=raw,unit=1,file="../OVMFbin/OVMF_VARS-pure-efi.fd" -net none
/bin/sh: 1: qemu-system-x86_64: not found
make: *** [Makefile:37: run] Error 127
I even then tried updating run.bat file to the latest pull request... and then I tried running make again, and it still failed giving the same error.
I did some research and found a working solution. The issue or problem is with the qemu installation.
In your video when you instruct your readers for installing qemu on linux distros, and not the windows - wsl version, you are telling them to install qemu as follows:
sudo apt install qemu
I even tried restarting Ubuntu and that didn't help...
Through my research and with the help of Chrome's Grepper extension tool... I found this method of installing qemu
sudo apt-get install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
I did this even after using your standard way of installing qemu, but this was more involved and took some time to complete, a good 5-7 minute process... After it finished I tried running make run and it worked! qemu successfully started and loaded the bootloader. I can now see "HelloWorld!" on the EFI screen!
