VirtualBox - Ubuntu 20.04 Server very very slow

[omexlux]

Thank you, I have now done it.

I suppose when a new GA is available (host) I have to repeat the procedure?

Thanks in advance.

Hi,

After all this the system is not really faster

[omexlux]

Could it be because the installation path is on an external hard drive?

EDIT: Also enabled now I/O on SATA, maybe it get better?

It could be, as you will be dependent on the speed of the USB (?) interface and also that of the external Hard Drive compared with your PC's own hardware. When I use an external 'drive' I normally use a USB 3/USB C connection and an external SSD and don't experience any noticeable fall off in speed over a similar VM running on the internal SSD on my system. You would need to compare like with like to identify hardware related 'speed' issues, e.g. move the VM to your main system and see if it runs better.

Sorry for the confusion, it is an internal hard disk (HDD) but not the main hard disk where the rest runs on.

I also checked now if hardware acceleration is enabled in bios, yes it is, in VirtualBox I have selected kvm, I can not find any other option to enable here.

Something need to be checked?
