I have two options under "Virtualization" in the BIOS: "Enable Intel 
Virtualization Technology (VT)" and "VT for Direct I/O". Both were 
enabled. Secure boot was also turned off. BIOS version is also at the 
most current version 1.1.1. Because of the dmesg errors Thomas Gleixner 
mentioned, I assume it would be best to contact Dell directly (even if 
I'm not sure if and how fast they will respond). If the driver would 
manage to work with only 1 vector, I assume this would also make it work 
on my configuration, even with possible performance hits.

Best,
