How to use virtualbox when host runs low-latency kernel

I have low-latency kernels installed on my ubuntu notebook because I often process live audio in real time with low latency, and I find that I can achieve smaller sound card buffer sizes with the low-latency kernels than with the generic kernels.

Sometimes I have to use virtualbox on the same notebook. I find that I cannot start virtualbox virtual machines when running a low-latency kernel. The error messages are included at the end of the question. I need to reboot into the generic kernel in order to be able to run virtualbox VMs. I remember that I was able to run virtualbox VMs also with the low-latency kernels in the past. Is there a workaround? The error messages suggest to reinstall virtualbox-dkms and to run 'modprobe vboxdrv', however, the first suggestion does not help, and the second suggestion does not succeed.

Error messages:

Failed to open a session for the virtual machine 'VM name'. Details: The virtual machine 'VM name' has terminated unexpectedly during startup with exit code 1 (0x1).

Result Code: NS_ERROR_FAILURE (0x80004005) Component: MachineWrap Interface: IMachine {some GUID}

Another error pops up before acknowledging the first error:

VirtualBox - Error un suplibOsinit

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please resintall virtualbox-dkms package and load the kernel module by executing

'modprobe vboxdrv'
