#14 Mouting root filesystem with error 19 in bhyve

Olivier Cochard-Labbe — Sun, 04 Jan 2015 19:01:46 -0000

Hi,

(thanks for the milestone reminder!)

I'm using bhyve for testing BSDRP: The VGA AND serial release works great with bhyve (VGA release has the serial port enabled by default).
For example, with my bhyve-lab-script (available on the BSDRP sources) I can start it without problem:

BSDRP/tools/BSDRP-lab-bhyve.sh -i /usr/obj/BSDRP.amd64/BSDRP-1.54-full-amd64-serial.img.xz

BSD Router Project (http://bsdrp.net) - bhyve full-meshed lab script
Setting-up a virtual lab with 1 VM(s):
- Working directory: /tmp/BSDRP
- Each VM have 1 core(s) and 256M RAM
- 1 LAN(s) between all VM
- Full mesh Ethernet links between each VM
VM 1 have the following NIC:
- vtnet0 connected to LAN number 1
For connecting to VM'serial console, you can use:
- VM 1 : cu -l /dev/nmdm1B

cu -l /dev/nmdm1B

Connected

Hi. Problem with BSDRP 1.54 (still no milestone v1.54 in sourceforge)

I've try to create BSDRP profile for cbsd ( https://github.com/olevole/cbsd/blob/master/etc/defaults/bhyve-freebsd-BSDRP-x64-1.54.conf ) but when i start bhyve-vm, system is unable to mount root with symptoms:

...
random: unblocking device.
Timecounter "TSC-low" frequency 1754922245 Hz quality 1000
Trying to mount root from ufs:/dev/ufs/BSDRPs1a [ro]...
mountroot: waiting for device /dev/ufs/BSDRPs1a ...
Mounting from ufs:/dev/ufs/BSDRPs1a failed with error 19.

Loader variables:
  vfs.root.mountfrom=ufs:/dev/ufs/BSDRPs1a
  vfs.root.mountfrom.options=ro

Manual root filesystem specification:
  <fstype>:<device> [options]
      Mount <device> using filesystem <fstype>
      and with the specified (optional) option list.

    eg. ufs:/dev/da0s1a
        zfs:tank
        cd9660:/dev/acd0 ro
          (which is equivalent to: mount -t cd9660 -o ro /dev/acd0 /)

  ?               List valid disk boot devices

  <empty line>    Abort manual input

mountroot> ?

List of GEOM managed disk devices:
  diskid/DISK-BHYVE-FE84-1567-A63 vtbd0

mountroot>

Also i've try to load directly from vtbd (virtio-blk):

mountroot> ufs:/dev/vtbd0s1 ro
Trying to mount root from ufs:/dev/vtbd0s1 [ro]...
mountroot: waiting for device /dev/vtbd0s1 ...
Mounting from ufs:/dev/vtbd0s1 failed with error 19.

When i change storage driver from virtio-blk to ahci-hd, the situation does not change

mountroot> ufs:/dev/ada0s1a
Trying to mount root from ufs:/dev/ada0s1a []...
mountroot: waiting for device /dev/ada0s1a ...
Mounting from ufs:/dev/ada0s1a failed with error 19.

Looks like image is ok:

Also, looks like all labels is present:

I have not tried to load vga image because bhive not support graphics.
Do you have any idea what could be the reason for such behavior? Thanks
