Problems booting old virtual machines

[boxino]

Some VMs no longer start. In fact, if I try to open them, they send me an error:

Code: Select all

The VMMR0.r0 module version does not match VBoxVMM.dll/so/dylib. If you just upgraded VirtualBox, please terminate all VMs and make sure that neither VBoxNetDHCP nor VBoxNetNAT is running. Then try again. If this error persists, try re-installing VirtualBox. (VERR_VMM_R0_VERSION_MISMATCH).
Codice uscita:
NS_ERROR_FAILURE (0X80004005)
Componente:
ConsoleWrap
Interfaccia:
IConsole {6ad89-6ee7-4e33-8ae6-b257b28}

The only way is to close all the others and then start them. Is there a way around this? VB 7.0.12 Linux Ubuntu 22.04.3 LTSHost,Winxp guest.

Check your Extension Pack version. The Virtualbox and Extension Pack versions should match.

The Virtualbox and Extension Pack versions should match.

While this is true, there are several other internal version numbers that also have to match. VBoxVMM.dll and VMMR0.r0 are both standard components of VirtualBox and not part of the VirtualBox Extension Pack.

Windows host specific advice: I'd suggest to uninstall VirtualBox (the VMs will be kept), reboot the host, delete the program folder (e.g. C:\Program Files\Oracle\VirtualBox) and re-install VirtualBox.

Linux host specific advice: I'd suggest to uninstall all VirtualBox packages (the VMs will be kept), reboot the host, and re-install VirtualBox.

Edit:
Previously, I overlooked that you're using a Linux host. Added specific advice above.

I also tried to create a new machine with XP but the problem remains identical. I tried to reinstall VB but it stays with the old version even unnstalling it. The same result remains at 7.09, version 7.0.12 is impossibile to install on this machine. Any further suggestions

According to fth0, you have a mix of Virtualbox versions installed, and apparently the uninstaller is not finding the mixed-up files.

You'll need to purge all Virtualbox program files (not the VMs or Virtualbox.xml) so there's no Official Virtualbox or Linux fork Virtualbox or any other Virtualbox on your Linux host, then you can install prerequisites and Official afresh, and you should be OK.

I resolve to reinstall operating system host and all programs.
Thank you!

Nuking it from orbit is also a solution.

The problem arises again...
