Hi! I've built FreeBSD 8.0-STABLE "LiveUSB" image using nanobsd script, it works with real hardware. I'd like to test it with VirtualBox to avoid rebooting too often. So, I've installed virtualbox-ose 3.1.4 from ports and tested it: - it boots Windows XP guest installed to VDI-disk just fine; - it boots FreeBSD "LiveCD" I've built as ISO image fine too; - virtual machine hangs just after reading first 512 bytes from RAW-dist made this way (/dev/da0 is USB flash drive): # VBoxManage internalcommands createrawvmdk \ -filename $HOME/.VirtualBox/HardDisks/usbdisk.vmdk \ -rawdisk /dev/da0 -register I've copied first 512 bytes from VDI image containing WinXP to file 'mbr' and installed it to USB flash drive using 'fdisk -B -b mbr da0' command and now VirtualBox boots and runs this "LiveUSB" with FreeBSD from real USB flash just fine too. nanobsd uses BootEasy as boot0 loader and I use this configuration to build it: NANO_BOOTLOADER="boot/boot0" NANO_BOOT0CFG="-o packet -s 1 -m 3 -t 36" So there is something wrong in BootEasy+VirtualBox+"RAW-disk" triple. How do I debug this? Eugene Grosbein
