This is a not so new laptop, with 8GB RAM. As I said, some of the time, even without modifying anything, sys-net and sys-usb just can't get started. Others, they do. If I balloon down dom0 before trying to starting them, like this: xl mem-set 0 1500 everything works. So far, instead of touching swiotlb, I've worked it around by passing "dom0_mem=1536,max:4096". With this, system VMs start at boot, and this is enough for me right now.
