Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select «Show Log» and save «VBox.log» (no other file) to a zip file. Attach the zip here.

But be warned. It looks to me like you have a problem with Kali, not a problem with VirtualBox.

I’m a newbie in this stuff. I hope I did what you said right.I am also using linux kali on the host.

First, you are using the Debian distros own build of VirtualBox, not the official version we support here.

Next, you installed a mismatched extension pack. This is not allowed.

So what should I do?

Kali Linux is based on Debian Linux.

You can ignore the vmwgfx error messages, which are a red herring.

My educated guess is that you don’t have a VirtualBox-specific problem. The (virtual) disk contents of your guest OS are probably damaged, and you’ll have to use the guest OS emergency methods or restore the guest OS from an earlier backup.

«Failed to send log host message.» error using Ubuntu on Windows 10 Pro Host

«Failed to send log host message.» error using Ubuntu on Windows 10 Pro Host

by onrocketfalls » 8. Jan 2021, 19:40

I’ve tried multiple solutions I’ve seen after looking through different threads with this same error, but I’m still not finding anything that will help me. On my laptop, I do still get the «Failed to send host log» message, but Ubuntu still boots. In this case, on a different PC, it will not boot after the message below. First, the problem, and then what I’ve tried so far:

After installing Ubuntu on the VM, when I try to start it, I get:
/dev/sda5: recovering journal
/dev/sda5: clean, 198517/2588672 files, 2251253/10353920 blocks
[ 9.295673] [drm:vmw_host_log [vmwgfx]] *ERROR* Failed to send host log message.
[ 9.297899] [drm:vmw_host_log [vmwgfx]] *ERROR* Failed to send host log message.
—

So far, I’ve tried:
— Giving it more memory to work with (up to half of my RAM, so 16gbs)
— Reinstalling Ubuntu (about five times)
— Changing the graphics controller to VBoxVGA (didn’t give the same text as above, but didn’t boot either)
— Changing the video memory up to 128mb
— Rebooting with and without the Ubuntu installation iso mounted
— Unchecking the floppy disk in the boot order, and also both unchecking and moving it to the bottom
— Moving the VM installation folder from my SSD where my host OS is to a HDD on the same PC

I have made sure virtualization is enabled in the startup menu and that it has also been enabled in Windows itself.

and maybe some other stuff I forgot, I was at it for like three hours last night trying stuff and retrying stuff I’d already tried. Shelled out for Windows 10 Pro to get virtualization, and then my gaming rig still can’t seem to do a thing that my semi-ancient work laptop with 6gb of RAM can do. pls help

Re: «Failed to send log host message.» error using Ubuntu on Windows 10 Pro Host

The «Failed to send host log message» error is apparently a bug in the Linux OS’s drivers that appears when the Virtualbox VMSVGA video card for Linux VMs is used. It can safely be ignored and does not interfere with the VM’s operation.

Hope you didn’t pay much. Though Home doesn’t have the ‘virtualization’ you probably thought you needed, it does have the underlying structure, called Hyper-V, which many times interferes with Virtualbox. (Home and Pro both have services that can use Hyper-V. Only Pro can run Hyper-V-based VMs. Read on. )

If this is a Windows PC, right-click the guest in the main Virtualbox window’s guest list, choose Show Log.

Search the far left tab’s log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled. If you are still running 6.1.14 or earlier, update to 6.1.16, and try again.

If the 6.1.16 log still shows these words, Hyper-V needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don’t find that text, save the far left tab’s log, zip the log file, and post the zip file, using the forum’s Upload Attachment tab.

I’m trying a fresh install now and while I’d love to get to where I can try what you said to try, I can’t even get to the install page. It shows Ubuntu, it shows the spinning loading icon, the icon freezes, and nothing progresses. What a cluster this is turning into. I’ll update as soon as I figure this new and exotic and extremely frustrating problem out (open to suggestions, though).

Edit: Checked the log just for the hell of it, though, and «Attempting fall back to NEM» was in there. I’ll try that route for this problem too.

Edit again: It worked. Thank you, thank you, thank you, thank you, thank you. And also, if you have any suggestions for what Windows 10 Pro is good for over Home, lmk. At least it was only $20.

P.S.: Thank you. I would have probably given up soon.

Great! Glad you’re up and running.

I didn’t know Home could go to Pro for only $20. I might have to do that on my Home laptop & tablet.

Pro has a few other things Home doesn’t have. Pro can join a domain, not much of a biggie for the average user, but good for the office.

The biggest benefit of Pro, to me, in the Windows 10 era, is better control of automatic updates, because of access to the Group Policy Editor. GPE has settings to notify but not download or apply updates until I give the go-ahead (and make sure VMs are all shut down first), which let’s me make backup images beforehand:

Start menu > Run. > gpedit.msc > Local Computer Policy > Administrative Templates > Windows Components > Windows Update > Configure Automatic Updates > set «Configure automatic updating» dropdown to 2 (Notify for download and auto install) or possibly 3 (Auto download and notify for install).

For me, the main advantage is that «Pro» has the ability to be an RDP (Remote Desktop Protocol) server. Home editions of Windows can be clients , i.e. they can RDP into RDP servers, but home editions can’t be RDP servers themselves: nothing can call into your home edition Windows PC. A server means that you can install Win10Pro on some small form factor (SFF) box (or single board computer — SBC) that sits in the corner of a room taking up almost no space, but when you need to you can RDP into it from your main PC and access whatever apps caused you to want that small PC in the first place. I have PCs in my home set up to prepare media for a NAS media server (it’s a Synology NAS, but it could have been another PC), I have a PiHole running (though that’s on a Raspberry Pi, also running an RDP server), and I’m considering other functions like my own fully functioned router that I can control better. It opens up a whole new level of gadgetry.

There are probably ways that you can force something similar to RDP server capability onto Win10 Home, but I frankly don’t trust such hacks, so for just a little extra I prefer to have the real thing.

No, no side effects on VirtualBox. This is not to hide error message, this is to solve the error. «nomodeset» says to kernel not load video drivers (xf86-video-vmware eg.) at boot. Instead, use bios settings till the system is properly ok.

Yes, no error. But i’ve tested only on openSUSE.

Ok, thanks for checking.

These «*ERROR*» messages do not indicate a real error anyway. Their background is well understood and explained in 19168#comment:4.

Thank you very much for this more detailed explanation! I tried to solve the «problem» myself, and I racked my brain trying to solve it. Then when the error stopped, I was so happy that I decided to try to help other people by posting on the forum.

It is a bug in Linux’s driver for the VMSVGA virtual video card. The VM continues to boot if it has no other problems.

The following error is from the OS, not Virtualbox. You’ll have to use the OS’s help channels to fix this one:

You may have broken something by

Random thrashing does not often help, rather it hurts. It is better, especially after getting on the forum to ask for help, to stop and wait for the help to arrive.

We cannot tell what was damaged in this VM. You may have to start over.

I even restored last working snapshot but it still gives me maintenance mode.

Is there bug in recent VirtualBox? or is this induce by Windows update?

The message «*ERROR* Failed to send host log message» from vmwgfx can be safely ignored, and seems to have no side-effects, can we just remove it already? Can I help?

I’m running Linux ubuntu 20.04 on VirtualBox 6.1 and I’m on windows 10. For the past weeks, it worked almost perfectly, I just once had a problem with a black screen but it was just a video memory issue.
When I tried to open it today for the first time after a week, the boot-up prompt displayed the following error message :
[drm:vmw_host_log [vmwgfx]] *ERROR* failed to send host log message
The ubuntu logo starts rotating, it disapears and I get a black screen.

I read a lot of advice on forums today, but I still can’t figure it out. So far, I tried:

• Changing the display settings from VMSVGA to VboxVGA or VboxSVGA. I don’t get this error in the prompt anymore, but I get an alert «invalid setting detected». It also leads to a black screen after the boot-up. I also tried to find help with that, but it failed. For the rest of these steps, I went back to the VMSVGA graphic controler.
• Turned off / on Windows Hypervisor Platform, Virtual Machine Platform in Windows Features.
• I apparently didn’t had access to Hyper-V, so I downloaded it. I first tried to disable it using the command lines
  bcdedit /set hypervisorlaunchtype off
DISM /Online /Disable-Feature:Microsoft-Hyper-V
  I went to check on Windows Features after restarting my pc and Hyper-V was downloaded but still activated. So I just unchecked the Hyper-V box from Windows Features. This also didn’t do anything to the error message.
• Increased video memory to 128Mb, and double my disk space up to 64Gb
• Disable DeviceGuard with gpdedit.msc, but my system seemingly doesn’t have it (it’s Windows 10 Pro only from what I read, I’m running Windows 10 Family). I also disabled Windows Defender’s Core Isolation.

Also, when I scroll to the bottom of my system informations, I have 4 lines related to hyper-v. The value (in the second column) is «yes», as shown in the picture
I think that this only shows if my system has the required configuration to use hyper-v though.

I have no clue what do to next as I’m very new to this type of environment. All the code I’m working with for a project is in this system and I really don’t want to lose it in the process.
Can anyone help me ?

Thanks a lot in advance !

Why does “drm:vmw_host_log [vmwgfx]] *ERROR* Failed to send host log message” show up and what can I do to fix it?
