  • Locate devices:

    camcontrol devlist

    Output; in this case only:

    <ST3500418AS CC35> at scbus3 target 0 lun 0 (pass0,ada0) <ST500DM002-1BD142 KC45> at scbus5 target 0 lun 0 (pass1,ada1) <AHCI SGPIO Enclosure 1.00 0001> at scbus9 target 0 lun 0 (ses0,pass2) <Generic STORAGE DEVICE 1532> at scbus10 target 0 lun 0 (da0,pass3) <Generic STORAGE DEVICE 1532> at scbus10 target 0 lun 1 (da1,pass4)

    Where ada0 and ada1 are mechanical drives, da0 is a miniSD card in a USB enclosure da1

    Or to print all partitions:

    gpart show

    Output (after formatting USB device):

    List partitions on dev da0:

    gpart show da0

    Delete existing partitions:

    gpart delete -i da0

    Destroy label:

    gpart destroy da0

    Create new mbr spanning entire disk:

    gpart create -s mbr da0

    Create new fat32 partition spanning entire disk:

    gpart add -t fat32 da0

    Initialize fat32 file system:

    newfs_msdos -F32 /dev/da0s1

    Lets break something!

    Don:undefined:’:undefined:t do any of this unless you are prepared to break it all, or better yet, you read the man pages and find out what they actually do, very useful tools however.

    I:undefined:’:undefined:m just making notes from other notes, various resources on the net.

    gpart destroy -F da0

    Zero out the drive === !!!Don:undefined:’:undefined:t do this jazz regularly on any USB!!! The type of memory has a finite read/write number===

    dd if=/dev/zero of=/dev/da0 bs=2m count=1

    Format the drive

    newfs_msdos -F32 /dev/da0s1

  • Alternatively or in addition to the above to install bhyve:

    pkg install vm-bhyve bhyve-firmware bhyve-rc-3 grub2-bhyve

    Output:

    To ensure binaries built with this toolchain find appropriate versions of the necessary run-time libraries, you may want to link using

    -Wl,-rpath=/usr/local/lib/gcc48

    For ports leveraging USE_GCC, USES=compiler, or USES=fortran this happens transparently.

    ===> NOTICE:

    This port is deprecated; you may wish to reconsider installing it:

    Unsupported by upstream. Use GCC 6 or newer instead:undefined:…:undefined: Message from vm-bhyve-1.1.8_1:

    To enable vm-bhyve, please add the following lines to /etc/rc.conf, depending on whether you are using ZFS storage or not. Please note that the directory or dataset specified should already exist.

    vm_enable="YES" vm_dir="zfs:pool/dataset"

    OR

    vm_enable="YES" vm_dir="/directory/path"

    Then run :

    vm init

    If upgrading from 1.0 or earlier, please note that the :undefined:‘:undefined:guest:undefined:’:undefined: configuration option is no longer used.

    Guests that are not using UEFI boot will need either loader=:undefined:“:undefined:grub:undefined:”:undefined: or loader=:undefined:“:undefined:bhyveload:undefined:”:undefined: in their configuration in order to make sure the correct loader is used.

    Message from bhyve-rc-3:

    Configuration is done completely though rc.conf. The rc script won:undefined:’:undefined:t touch any devices for you (neither disk, nor tap) so you need to make sure all of those have been initialized properly.

    General setup:

    kldload vmm net.link.tap.up_on_open=1

    Make it persistent:

    echo "net.link.tap.up_on_open=1" >> /etc/sysctl.conf cat >> /boot/loader.conf << EOF vmm_load="YES" EOF

    Minimal example:

    cat >> /etc/rc.conf << EOF cloned_interfaces="tap0 bridge0" bhyve_enable="YES" bhyve_diskdev="/dev/zvol/anything/bhyve/virt" EOF ifconfig tap0 create ifconfig bridge0 create service bhyve start tmux list-sessions tmux attach -t bhyve service bhyve status service bhyve stop

    Multi profile configuration example:

    cat >> /etc/rc.conf << EOF cloned_interfaces="tap0 tap1 bridge0" bhyve_enable="YES" bhyve_profiles="virt1 virt2" bhyve_virt1_diskdev="/dev/zvol/anything/bhyve/virt1" bhyve_virt2_tapdev="tap1" bhyve_virt2_diskdev="/dev/zvol/anything/bhyve/virt2" bhyve_virt2_memsize="8192" bhyve_virt2_ncpu="4" EOF ifconfig tap0 create ifconfig tap1 create ifconfig bridge0 create service bhyve start # start all service bhyve start virt2 # start individual tmux attach -t bhyve_virt1 tmux attach -t bhyve_virt1 service bhyve stop virt2 # stop individual service bhyve stop # stop all

    (by default ctrl-b d detaches from tmux).
