Hi everyone,

I wanted to start my Windows 7 VM that worked just fine with the 4.4.4 kernel, but every time I want to boot into the virtual OS it just crashes, this is the log displayed:

Failed to open a session for the virtual machine Windows 7.

The device helper structure version has changed.

If you have upgraded VirtualBox recently, please make sure you have terminated all VMs and upgraded any extension packs. If this error persists, try re-installing VirtualBox. (VERR_PDM_DEVHLPR3_VERSION_MISMATCH).

Result Code: NS_ERROR_FAILURE (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I'm running the kernel 4.4.6-300.fc23.x86_64

I already tried reinstalling virtualbox and launching it with kernel-4.4.4 and 4.4.2 and also crashes on both versions.

I you had installed VirtualBox on a previus kernel version you need to update virtualbox, Fedora normally update its kernels faster that VirtualBox, so VirtualBox kernel modules will not exists for the new kernel, you can try using akmod for virtualbox which is will compile a new kernel module when it update the kernel at least on theory.

You better use libvirt and kvm with virt-manager to avoid issues with VirtualBox on Fedora. You can virtualize any thing with it.

Thanks for the quick answer. I didn't find any suitable kernel modules for the 4.4.6 version but, I followed your advice and started using KVM, do you have any recommendations to improve the performance on a Windows 7 VM running in KVM?

Good, you can use spice to connec to to you windows vm, check this article that has some tips to increase performance for what I see all of them can be set with virt-manager

You can see this error because mismatched version of VirtualBox and Extension Pack. For example I got this error after auto update of VirtualBox to 5.0.16 version, but VirtualBox Extension Pack left 5.0.14. Extension Pack is not a part of default installation.

Try to check for updates (File\Check For Updates ...). It will check that version is up today and will advise to download and install correct Extension Pack, if you have old one.
