Troubleshooting virtualbox problems

Hi all,

I have a newly installed PC with EndeavourOS where Virtualbox 6.1.14 is installed.
The only box is a W10 1909. The same box was used in the last years on a PC with Ubuntu 16.04.
After switching to EOS I found that the performance of Virtualbox is worse than on Ubuntu. This is really strange, because the new PC is a i3-9100 and the PC before is a i5-3470.

I have checked all logfiles, but I can not see errors or warnings that would guide me to the cause of the problem. Searching the forum did not give me a hint, where I can start my search to troubleshoot this problem.

Any hint is appreciated!

Kind regards

Post inxi from both.

There is only one 3770K from 2012 (seems better then the new ones) but many 3470 9100.
The difference between i5-3470 and i3-9100T is not big.
And your feeling (I found) :wink: is not a recognized unit of measurement.

I only can provide the inxi output from the new PC, because the old Ubuntu installation is already deleted …

The former PC is a i5-3470S to be correct. The main performance is not the processor but the hard drive. I can see with system monitor or iotop that it is lower than 5MB/s. The hard drive is the ID-2 in the list above.

Any ideas where to search?

Could you show the setup of your Vbox ?

(The only box is a W10 1909)
So does this mean you have Windows 10 on the computer with EndeavourOS installed on virtualbox?

The i3-9100 is as @SGS say’s not much different than the i5-3470 other than it’s memory support for DDR4 2400. The memory is faster but the processor difference is negligible. I do see that Gnome is using twice the ram that my Plasma install is using. You do have 16 GB memory but it’s not always how much memory you have but what processes and or services that are running and tying up the cpu. My suggestion would be to try Xfce. Or even Plasma if you are using it in vbox as you can try what ever you like then.

hello ,which kernel module do you use

See screenshot. Sorry it is german! :wink:


No, vice versa.
I am running EOS with Gnome and W10 is in the VBox.

Thanks for the ideas. Memory is related to the fact, that I have a lot of services running on that PC (DNS, DHCP, LDAP, NFS, Apache, Maria-DB etc.). All those services have been running on the previous PC too.


I also tried virtualbox-host-dkms, but this did not help.

Okay so are you having the issue then with Windows 10 being slow on virtualbox? Or just EOS gnome?

EOS Gnome is fine and running like I expect.
W10 in the VBox, especially the hard drive performance is my problem. The W10 Vbox needs more than three minutes for the startup.

how much ram do you put for your VM

Definitely something isn’t right there. I would suspect it more to be with the Windows install on v-box than with EOS. 3 Minutes … ??? Hmm? :thinking:


I have windows 10 in Virtualbox, running on EOS. Boots in less than 20 seconds…so maybe you can check against some of my settings?

Yes, I would appreciate to check against your settings. See mine in the screenshot above.

that’s what i put for my VMs

I changed the settings of my W10 VBox to yours. But still the startup is very slow.
What I can see is a high IOWAIT percentage up to 150% or more.

maybe try turning on use host i/o cache, as you are running more services on your machine than I am? Also see if you can bump the ram allocated?iohost
