I see the FreeBSD loader, giving me the traditional options, after the timeout I see it loads the kernel and modules (basically opensolaris.ko and zfs.ko) and then, instead of showing the me boot info as usual, the machine shows me a cursor for a while and then reboots. The test machine is an i7-3540M. The FreeBSD version is: FreeBSD 11.0-CURRENT #4 r279875+f0e745a(HEAD): Sat Mar 14 16:55:11 CET 2015 and I'd say EPT and IOMMU are available: # [gus@portgus /usr/home/gus]$ dmesg|grep EPT VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID # [root@portgus /usr/home/gus]# acpidump -t | grep DMAR DMAR: Length=184, Revision=1, Checksum=194, I tried booting with verbose, but it did the same, the machine tried to boot and then it rebooted. The laptop does not have a ttyu1 (com1) port. Does this affect? I wonder why I don't see any message in the console. Is that because of the xen_cmdline option in the loader? Would it be useful if get trace via the video or serial consoles? If so, how I do get those traces, by tweaking the xen_cmdline option? Best, Gustau
