Add instructions for QEMU to documentation

[hw-claudio]

Hello,

tried both:

hello-0.4.0_0D11-FreeBSD-13.0-amd64.iso,
hello-0.4.0_0D26-FreeBSD-12.1-amd64.iso

and they both boot to rescue disk for me:

qemu-system-x86_64 --enable-kvm hello-0.4.0_0D11-FreeBSD-13.0-amd64.iso

Enter full pathname of shell or RETURN for /rescue/sh

Hello @hw-claudio, thanks for testing.

Some time ago, I had helloSystem running as a guest on QEMU on helloSystem as a host:
#25 (comment)

• Did you assign at least 4 GB RAM to the virtual machine?
• Did you use BIOS mode (no UEFI)?

On https://app.element.io/#/room/%23helloSystem:matrix.org we got this information:

boot and install of hellosystem worked on qemu on linux x86_64. only thing i needed to do with qemu was to increase the memory from 2 gigs to 4 gigs and remove the usb mouse (tablet) settings

I'm running qemu on Fedora 32 x86_64.

Here are the qemu options I used to boot hellosystem in qemu:

qemu-system-x86_64 -machine type=q35,accel=kvm \
-enable-kvm -cpu host -smp 2 -m 4096 \
-device virtio-net,netdev=vmnic -netdev user,id=vmnic,hostfwd=tcp::5222-:22 \
-vga std -soundhw hda -no-quit \
-drive format=raw,file=${HOME}/.qemu/hellosystem/hellosystem.img

For the first boot I also used these qemu options but removed them when it was installed on the qemu disk:

-drive format=raw,file=${HOME}/Downloads/hello-0.4.0_0D26-FreeBSD-12.1-amd64.iso \
-boot menu=on

@hw-claudio can you please try those exact settings? If they work for many users, we may want to add them to https://hellosystem.github.io/docs/user/getting-started.html#tested-virtualization-environments

To boot/install in UEFI mode, first install OVMF Open Virtual Machine Firmware on your qemu host side.

The package name for Fedora 32 is edk2-ovmf.

Then add these two qemu options for the VM start:

-bios /usr/share/edk2/ovmf/OVMF_CODE.fd \
-smbios type=0,vendor=0vendor,version=0version,date=0date,release=0.0,uefi=on

I found out if i use -vga std instead of -vga virtio in qemu, I get the full resolution, not just 800x600.
I'll edit my previous comment here.

Let's add this information to https://github.com/helloSystem/docs/blob/main/user/getting-started.md#tested-virtualization-environments. Do you want to edit that page?

Instructions have been added to the helloSystem documentation. Thank you very much. 👍
