 |
|
Hi,
I am installing Gentoo on Oracle VirtualBox for learning/testing purposes. During the installation, there is a video card configuration. In the host system I am using an Intel base card ( https://ibb.co/XZd2FJ7 ) so in the VirtualBox what variable may I add
https://packages.gentoo.org/useflags/expand#video_cards
Please guide me what entry may I add in /etc/portage/make.conf for VIDEO_CARDS=
Note:- I shall install Xfce as a desktop environment

gardenair,
Inside the VM, what does lspci -nnk say about your video card?
You probably want virtualbox, but there are other possibilities too.
A real video card hardware driver would only be required if you were doing video card pass through.
That's not a topic when you are starting out with virtual machines though.

If the virtual machine's graphics controller is set to VMSVGA, the default for [GNU]/Linux guests, then VIDEO_CARDS should be vmware.

No, like I said in my previous post, it's:
| Code: | | VIDEO_CARDS="vmware" |

What is the reason/logic to use "vmware" instead of "VMSVGA" ?
If we see the ground reality Oracle VirtualBox shows a Grapgic Controller VMSVGA |

gardenair,
Your image shows that you are in the chroot. That means that is required to install the lspci command.
VMSVGA means Virtual Machine SVGA. that's the host end. A few words on what Virtualisation does.
The virtualiser, here Virtualbox (there are others) is a piece of software that creates the appearance of another computer.
That's right down to the BIOS/EFI firmware. The illusion is so good that operating systems running inside the virtual machine cannot detect that they are not running on real hardware.
The virtualiser will fake hardware for the guest to use.
As the virtual environment is completely isolated from the real hardware, you must install drivers for the virtual hardware.
The host hardware is irrelevant.
If you provide the output for the virtual video card we can explain the logic behind the VIDEO_CARDS setting.

Gentoo just named the USE flag that way. And per the VirtualBox documentation, "for Linux guests, the default graphics device emulates a VMware SVGA graphics device" (referring to the VMSVGA controller). The controller advertises itself to the kernel as "VMware SVGA II adapter", and uses the vmwgfx kernel module, which is enabled in the kernel configuration with option:
| Code: | Graphics support
< > DRM driver for VMware Virtual GPU |

gardenair,
lspci -nnk says you have a VMware SVGA II Adaptor. [15ad:0405]
The vendor and device IDs are 15ad:0405, which are the bits I really wanted.
Searching for 15ad:0405 PCI site:cateee.net says that the kernel symbol is | Code: | | CONFIG_DRM_VMWGFX: DRM driver for VMware Virtual GPU |
lists all possible VIDEO_CARDS="amdgpu fbdev radeonsi vesa -ast -dummy -freedreno -geode -i915 -intel -mga -nouveau -nvidia -omap -qxl -r128 -radeon -siliconmotion -tegra -vc4 -via -virtualbox -vmware")
As you have VMware Virtual GPU, you need VIDEO_CARDS="vmware"
