FreeBSD/i386 10.4-RELEASE running as a guest operating system on VirtualBox can have a problem with disk I/O access. It depends on some specific hardware configuration and does not depend on a specific version of VirtualBox or host operating system.
It has been reported that instability may be present on virtual machines running on other hypervisors, such as Xen or KVM.
It causes various errors and makes FreeBSD quite unstable.
Although the cause is still unclear, disabling unmapped I/O
works as a workaround. To disable it, choose
Escape to loader prompt in the boot menu
and enter the following lines from loader(8) prompt,
after an OK:
set vfs.unmapped_buf_allowed=0 boot
Note that the following line has to be added to
/boot/loader.conf after a boot. It
disables unmapped I/O at every boot:
vfs.unmapped_buf_allowed=0
FreeBSD/i386 10.4-RELEASE installed on ZFS
may crash during boot when the ZFS pool mount is attempted
while booting an unmodified GENERIC
kernel.
As described in /usr/src/UPDATING
entry 20121223, rebuilding the kernel
with options KSTACK_PAGES=4 has been
observed to resolve the boot-time crash. This, however, is
not an ideal solution for inclusion in the
GENERIC kernel configuration, as
increasing KSTACK_PAGES implicitly
decreases available usermode threads in an environment that
is already resource-starved.
Taking into account the heavy resource requirements of
ZFS, in addition to the i386-specific tuning
requirements for general workloads, using ZFS with the
FreeBSD/i386 GENERIC kernel
is strongly discouraged.
If installing FreeBSD/i386 on ZFS, it is possible to
configure the system after installation to increase the
KSTACK_PAGES.
When prompted by bsdinstall(8) to perform additional post-installation configuration to the system, select .
This procedure requires the system sources available
locally. If the System source code
distribution was not selected during installation, it can
be obtained using svnlite:
#mkdir -p /usr/src#svnlite co https://svn.freebsd.org/base/releng/10.4 /usr/src
Build the kernel-toolchain required
to rebuild the kernel:
# make -C /usr/src kernel-toolchainNext, create a kernel configuration file to increase the
KSTACK_PAGES option:
#printf "include GENERIC\noptions KSTACK_PAGES=4\n" >/usr/src/sys/i386/conf/ZFS
Then build and install the
ZFS kernel:
#make -C /usr/src buildkernel KERNCONF=ZFS#make -C /usr/src installkernel KERNCONF=ZFS
It is extremely important to take note that, by
default, freebsd-update(8) will install the
GENERIC kernel configuration, and
as such, freebsd-update(8) consumers are strongly
encouraged to avoid FreeBSD-provided kernel binary upgrades
with such configurations.
Due to an incompatibility between bsdconfig(8) and pkg(8), packages included on the FreeBSD dvd installer will not be recognized by bsdconfig(8).
To install packages from the dvd1.iso
installer, create the /dist target directory, and
manually mount the dvd1.iso
ISO:
#mkdir -p /dist#mount -t cd9660 /dev/cd0/dist
Be sure to use the correct /dev device path for the
dvd1.iso ISO
installer.
Next, set REPOS_DIR to the path of the
repos/ directory
within the installer so pkg(8) will use the correct
repository metadata.
If using sh(1):
# export REPOS_DIR=/dist/packages/reposIf using csh(1):
# setenv REPOS_DIR /dist/packages/reposKeep in mind that REPOS_DIR will need
to be set again after the current shell session is
terminated, if continuing to use the packages provided on
the dvd1.iso installer.
Finally, bootstrap pkg(8) from the ISO, and install required packages:
#pkg bootstrap#pkg installxorg-serverxorggnome3[...]
An issue with FreeBSD virtual machines with
vagrant was discovered that
affects the VirtualBox where the
virtual machine will not start on the initial boot invoked
with vagrant up.
The issue is due to the virtual machine
MAC being unset, as FreeBSD does not provide
a default Vagrantfile.
It has been observed, however, that a subsequent
invocation of vagrant up will allow the
virtual machine to successfully boot, allowing access via
vagrant ssh.

FreeBSD/i386 installed on ZFS may crash during boot
when the ZFS pool mount is attempted while booting an
unmodified GENERIC kernel.
A system tunable has been added as of revision
r286584 to make the
kern.kstack_pages tunable configurable
without recompiling the kernel.
To mitigate system crashes with such configurations,
choose Escape to loader prompt in the
boot menu and enter the following lines from loader(8)
prompt, after an OK:
set kern.kstack_pages=4 boot
Add this line to
/boot/loader.conf for the change to
persist across reboots:
kern.kstack_pages=4
[2017-07-21] Due to a bug in earlier versions of clang(1) that is difficult to work around in the upgrade process, to upgrade the system from sources via buildworld to -CURRENT or 11.1-RELEASE, it is necessary to upgrade machines running 9.x to at least revision r286035, or machines running 10.x to revision r286033. Source-based upgrades from 10.3-RELEASE are not affected. This differs from the historical situation where one could generally upgrade from anywhere on earlier stable branches, so caution should be exercised.
[2017-07-25] FreeBSD/arm64 currently lacks EFI real-time clock (RTC) support, which may cause the system to boot with the wrong time set.
As a workaround, either enable ntpdate(8) or
include ntpd_sync_on_start="YES" in
rc.conf(5).
[2017-07-25] A late issue was discovered with FreeBSD/arm64 and "root on ZFS" installations where the root ZFS pool would fail to be located.
There currently is no workaround.
[2017-07-26] Note for those upgrading from 11.1-RC2 in VirtualBox:
If system panics were experienced when upgrading from
11.1-RC1 to 11.1-RC2, and the emulators/virtualbox-ose-additions{,-nox11}
port was built locally as a resolution, the port will either
need to be rebuilt when upgrading from 11.1-RC2 to
11.1-RELEASE, or reinstall the package from the pkg(8)
mirrors using either:
#pkg install -f virtualbox-ose-additions
or
#pkg install -f virtualbox-ose-additions-nox11
To ensure the system does not panic after rebooting into
the updated kernel, it is recommended to disable the
vboxguest service in rc.conf(5)
prior to rebooting the system if possible, or use
pkg(8) to forcefully reinstall the package.
Systems being upgraded from 11.1-RC1 and earlier and 11.1-RC3 to 11.1-RELEASE should be unaffected.
[2017-07-27] The release notes erroneously state
revision r315330 was sponsored by Rubicon
Communications, LLC (Netgate), when in fact this work was
done by Hiroki Mori independently.
[2017-08-09] The release notes stated the ruptime(1), rwho(1), and rwhod(8) utilities have been marked "deprecated", however this change was reversed in 12.0-CURRENT.
The other utilities mentioned in the entry in the release notes, however, are unchanged.
[2017-11-06] An issue with FreeBSD virtual machines with
vagrant was discovered that
affects the VirtualBox where the
virtual machine will not start on the initial boot invoked
with vagrant up.
The issue is due to the virtual machine
MAC being unset, as FreeBSD does not provide
a default Vagrantfile.
It has been observed, however, that a subsequent
invocation of vagrant up will allow the
virtual machine to successfully boot, allowing access via
vagrant ssh.
