Update Readme.md to specify operating system compatibility in Virtual x86

Read the title to see what this PR is about :)

We don't really need to name every Linux distribution. How about just Fedora, the is based on Debian or Ubuntu anyway.

[spetterman66]

yeah, good reason

better?

Looks good now. That said, does Fedora 30 actually work?

[spetterman66]

yes. see the screenshots i posted in the gitter discussion channel

I can't reproduce it, does only the LXDE version work?

[spetterman66]

What specifications have you allocated to the virtual machine? Give it 2048MB RAM, 128MB VRAM, and keep ACPI off (Because it's not required for correct operation). Use the boot arguments loglevel=7 earlyprintk=serial,keep for best verbosity (By pressing the tab key on the boot options screen), and to get info where it gets stuck at.

As you can see in the screenshot below, Fedora 30 (i386, LXDE) works fine in Virtual x86. I have not tried other spins. (BTW, loading desktop, but it loaded cursor so it works :)

Does it work correctly? I wouldn't expect any distro (not even bloated ones) to take more than a few minutes to boot.

It looks like Fedora 30 just outright works (although very slowly unless you are using one of the optional desktop environments.

• Fedora-Workstation-Live-i386-30-1.2.iso Booted to the live image about 8.5 min, but once it got to that point performance was awful and it's not even worth attempting, moving the mouse would be met with 30+ second long delays.
• Fedora-LXDE-Live-i386-30-1.2.iso Got me to a complete LiveCD desktop in about 7 min and felt very usable in performance.
• Fedora-LXQt-Live-i386-30-1.2.iso Took about 6min to get the LiveCD to the desktop and once again felt very usable.
• Fedora-Xfce-Live-i386-30-1.2.iso Took about 10 min for the LiveCD to get to the desktop and again performance felt fine.

These were tested with 2048MB of RAM and 64MB of VRAM allocated in the VM. ACPI was disabled and in all cases I used the default live image option that I was presented with.

I'm guessing the very long boot time in that other screenshot was either because of the boot arguments that were used or potentially a slow host was being used. I am testing things with an i7 13700K so it's somewhat a best-case scenario for CPU performance.

Hmm, indeed. It's similarly slow in qemu-kvm, so let's assume v86 isn't at fault here.
