Incomplete installation on VB

[Centaro]

Hi everyone! I am trying to install CentOS 0.1905 on an Oracle VM. I have tried downloading the ISO from different mirrors, but the installation process always crashes almost at the end. It is a beautiful error

This happens after installing the files and during or after the file configurations.

My OVB settings for the VM

There are in Danish, but I only change CPU cores, RAM size, HDD size, graphic memory size, Graphics controller and USB driver

Actualy have you tried with Vbox defaults?
Another approach is to install in text mode (it's more limited) via pressing a tab and appending 'inst.text' and pressing enter .

The OVB defaults do not meet the minimum requirements for the system. Other than that I just change the graphics and usb settings.

Yes, this is a known problem with the vbox vboxsvga choice in your VM settings under the Display tab. Either change it to vmsvga in the vbox VM setting or, alternatively, you can use the vbox hostkey to switch to a different terminal and back and that fixes the display and makes it readable. Use vbox-hostkey-F2 to switch to terminal 2 then vbox-hostkey+F6 to switch back to the installer GUI and it should now be ok and readable again.

It is weird. I have a fresh Centos 8 installed in a VBox 6 hosted on Fedora. I didn't experience any issue.

VBox 6 of sufficient newness uses the vmsvga video controller for new linux guests by default. VBox 5 doesn't have it at all which means you need the switch-VT bypass. Older VMs created using any version of vbox 5 or an older vbox 6 will have it set to vboxvga or vboxsvga, both of which suffer from this problem and will need the setting changed in vbox.

I am actually usin VB 6 and the issue is present. Switching terminals did though help. My problem now is that after rebooting and dismounting the image, the OS won't load after the kernel is selected in the boot manager … there is just a blinking underscore and other terminals are unusable.

After sitting for a while this error appears

Code: Select all

db_root: cannot open: /etc/target

If you use vbox 6 and this was an existing VM and you upgraded from vbox 5 then it will have the old '5' defauilt of vboxvga and that suffers from the problem. To fix it you can change the VM display settings to vmsvga which is new in vbox 6.

Very much! Thank you for your help everyone! =)

Is there no way to mark the topic as solved or mark the answer?
