To make testing easier: I removed everything from loader.conf and I removed a few drivers(bge and a few others) that were built-in the kernel, so the host kernel won't use them and now I am testing with kenv and loading and unloading vmm.ko. I always see the correct ppt devices in the dmesg when vmm.ko is loaded. > > If you already have loader.conf configured correctly, you can try to > manually load vmm.ko once system is booted and see dmesg for any problem > in loading it like kernel mismatch, missing symbol[One common I usually > encounter is KTRACE define in sys/modules/vmm/Makefile but kernel config > is missing “option KTRACE”] etc. Everything seems ok here as well, I get nothing but the ppt devices. One thing I noticed and seems different is this: > ppt0 mem 0xb3430000-0xb343ffff,0xb3440000-0xb344ffff irq 16 at device 0.0 on pci2 > ppt1 mem 0xb3400000-0xb340ffff irq 17 at device 0.1 on pci2 > ppt2 mem 0xb3410000-0xb341ffff irq 17 at device 0.2 on pci2 > ppt3 mem 0xb3420000-0xb342ffff irq 17 at device 0.3 on pci2 so ppt0 (the bge device) has two mem ranges... Another thing I should mention is that "acpidump -t | grep DMAR" reports nothing. It is mentioned in the documentation but I didn't see until now.
