Setup & Installation / Re: ArcaOS5 - My personal experience by Sigurd
« on: January 06, 2019, 12:37:31 pm »Scenario 3: It tried an Installation in Virtualbox 5.1.22 inside Windows 10 Pro 64 1703 on the Surface Pro 4.
Result: Perfect!
Did perfection include getting SMP to work (multiple processors) ? I couldn't get that part to work in Virtualbox with ArcaOS 5.0.3 .
Also, with the VirtualBox extensions, I couldn't find a way to select a custom resolution.
My real monitor is UHD 4K - 3840x2160 . The highest resolution available is 1600x1200 . I know about scaling in VB, but would like to see if it's possible to do better than that.
1) SMP does not work in Virtualbox and it likely never will. You are not alone. What I did was to use the SMP kernel and limit the number of CPUs with PSD=ACPI.PSD /MAXCPU=1 but you could also use the W4 kernel without any PSD
2) in order to use custom resolutions with either GENGRADD or PANORAMA you will need to add one for the virtual image itself.
For that you use vboxmanage with the "setextradata" command like so:
vboxmanage setextradata "VM name" "CustomVideoMode1" "3840x2160x32" (that is x-size x y-size x bit depth)
You find vboxmanage.exe in the Virtualbox installation directory.
What this essentially does is add a new BIOS screen resolution which can then be queried by GENGRADD or Panorama.
