Virtualbox 5/6 very slow on Ryzen 1800X and Kernel 5.1.x (#18753)

ModEdit; related ticket: #18753: Linux Host: VMs on Virtualbox 6.0.x are running abnormaly slow on modern AMD Processors

Hi,

I'm experiencing an issue with my computer and virtualbox, suddenly I've discovered that my VMs run incredibly slow, both CPU and Graphically.

VMs boot slowly and take forever to do anything, in particular a debian 9 vm took me more than 1h to update via APT.

Previously the same VM on the same host computer was so fast I could even edit video using KDENLive inside the VM, however now it struggles even to move a window over the Mate desktop.

I've tried with Vitualbox 5.2.x and 6.0.x, all vga modes I've tried the test build VirtualBox-6.0.9-131597-Linux_amd64.run, always the same result, VMs are sluggish including a Windows XP one that alwas was super fast now it is so sluggish even the boot animation is slow.

I think this might have started after upgrading to kernel 5.0/5.1, this machine used to run VMs like a champ in Vbox before, thing is I have an intel computer running the same 5.1.15 kernel where virtualbox 6.0.8 performs great, so issue might be AMD specific.

Please find attached a dump of dmidecode and the vbox.log ( vbox 6.0.8 ) starting and stopping the affected debian VM.

Nothing else is slow on this computer, and it is rock solid stable (after disabling CPU C6 state that is).

Any help is welcomed.

Tried with kernel 4.18.0-25 and the same results, all VMs are very slow.

I've tried to deploy the same Debian 9 OS on a KVM based virtual machine in the same Ryzen computer, it literally flies in comparison with VirtualBox 6.x, it runs at about the same speed VirtualBox used to run before this issue.

As Kernel 5.2 has been released I will try to upgrade to it and see if it makes a difference.

There isn't anything obvious jumps out from the VBox.log file. You certainly aren't overcommitting resources to the guest and starving the host. I think it may be worth disabling, one at a time, some of the guest features and see if anything improves the situation. I would start by disabling 3D graphics, then audio, then switching the vGPU to VBoxVGA.

I'm also having trouble with this. In fact if you do a search of all the complaints of slow systems it seems Linux Host and AMD cpu feature in the common list.

I've got an older AMD 8150 8 core and at some point it start to run really really slow. Usable, just, No errors, just way slow.

I've tried changing everything andyp73 suggests, plus 2d acceleration, delete and reinstall guest additions, all video options. All to no avail.

These kinds of problems that are reproducible, should be reported to the bug tracker. Either search for an appropriate bug, or open a new bug report where you'll attach your logs and other vital information.

It would also help if you can post the bug report number here so other can see the progress, add information, or see the final resolution.

The sole reason in my case for opening a thread here is because on the bug tracker I saw a recommendation that for this type of "out of the blue inexplicably slow issue" it is better to open a thread in the forum. :lol:

Also "my computer is slow" is too vague for a bug tracker, after all I could be doing something wrong, it is clear now that there is some kind of issue with AMD after other people have confirmed they too are experiencing weird performance issues. :D

Regardless, if I disable the 3D acceleration some distros perform a bit better, specially Debian 9.x and CentOS 7.x Ubuntu 16.04.x/18.04.x is slow as molasses regardless of what I enable/disable.

Windows XP is completely crippled and Windows 8.1 is very slow but usable.

Hope this helps.

I also tried to install a different kernel (Liquorix 5.1.0.17) and no change.

That would most probably have been me! :D

I'm trying to lessen the load for the developers in areas where 1) there's nothing out of the ordinary to report, 2) it has already been reported. Yours doesn't sound like it fits the pattern.

One of the problems is that most people are using Intel CPUs, so it's not easily reproducible by an experienced VirtualBox user. That's why I said to hit the bug tracker, the developers have AMD systems.

Added ticket information, thankfully I was able to link 'JPFSanders' in the forums, with 'Sanders' in the bug tracker, not that difficult... ;)

Can I ask (out of curiosity) why you didn't use the same username/nickname?

I did the bug report very quickly as I had some work soon afterwards, I think the browser might have auto-completed, also looking at the ticket it doesn't state Linux Host, which probably was me not setting it either.

Many thanks for linking both, sorry to give you extra work. :(

Is there any way to change the nick on the bug tracker?

I had the same issue, I am a developer (PHP,ROR,mysql,postgresql,etc) and I have several virtual machines, OS: debian 7x,8x,9.x,Centos,Win7,win server,etc, all my guests were OK even running four at the same time on Intel, but after a migration from Intel I3 6100u to Ryzen 5 3500U- 16GBRAM all my virtual machines went so slow, i.e. just to move the cursor it was a delay beetween 1 or 2 seconds, almost impossible to work. I tried re-installing virtual machines, guest addons, changing display, ram, cores,3d, 2d, everything and nothing worked. Today, I am so happy (after a couple of months), I just made a downgrade VirtualBox 6.x to the latest VirtualBox 5.x (5.2.34) (released October 15 2019) and now everything is running like before or better. Hope this works for everybody using ryzen. PS. My Host is Windows 10 Pro

@franciscofruiz,
Just an FYI... the developers work with both kinds of CPUs. If there was a widespread, AMD-specific issue, I'm sure that they would be the first ones noticing and complaining...

And since they have the "know-how", they would have fixed the issue in less time than it took you to register in the forums! :)

I tried VirtualBox on AMD processor and Intel processor... on Ryzen (Ryzen 7 1700x) with same settings everything is very slow, on Intel (Intel 4770k) is working normal.

I'm seeing similar reproducible very laggy perf with Win10 guests on VB 6.1.0 hosts, with Ryzen 7 3700X CPU. All's good on older CPUs.
