FWIW, the vbox capture feature is pretty buggy - it doesn't create the file when it says it is recording, and it frequently crashes. It is possible the panic above is from #281 instead, because I deleted the video before I realizing this. Below is definitely from #282. <snip> Welcome to the OpenBSD/amd64 6.4 installation program. fatal protection fault in supervisor mode trap type 4 code 0 rip ffffffff810f4244 cs 8 rflags 10286 cr2 6c1fed cpl a rsp ffff800022098800 gsbase 0xffffffff81870ff0 kgsbase 0x0 panic: trap type 4, code 0, pc=0x ffffffff810f4244 syncing disks... done dump to dev 17,1 not possible rebooting... </snip> Hope this is actually useful and not another stupid VirtualBox bug. --david
