modify DKMS configuration file /etc/dkms/framework.conf 
Lower parallel compilation jobs to 1 if less than 2 GB RAM to avoid freezing of virtual machines.

`parallel_jobs=1`

This does not necessarily belong into security-misc, however likely
security-misc will need to modify `/etc/dkms/framework.conf` in the future to
enable kernel module signing.
