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-SA-18:08.tcp | 06 August 2018 | Resource exhaustion in TCP + reassembly |
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
[2017-07-25] 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.
[2017-11-06] 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.
[2018-06-21] An issue had been discovered late in the release cycle where removing ZFS vdevs from a pool under certain conditions would cause a system crash when zfsd(8) is enabled in rc.conf(5).
At present, it is believed to be limited to removal of
a mirror vdev from a pool consisting of
multiple mirror vdevs.
See PR 228750 for more information and updates as the issue is investigated.
[2018-06-26] An issue had been discovered late in the
release cycle where a system crash could occur after
installing emulators/virtualbox-ose from
upstream package mirrors via pkg(8).
Building emulators/virtualbox-ose from
the ports(7) collection has been observed to work
around the crash.
See PR 228535 for more information.
[2018-06-26] It was discovered after the releng/11.2 branch was tagged
for FreeBSD 11.2-RELEASE that a few device drivers were
missing from the hardware
page. The missing drivers, alc(4), cxgbev(4),
liquidio(4), and mos(4) were added to the
11-STABLE hardware
page.
[2018-06-26] The URL to the
instructions for source-based upgrades in
UPDATING incorrectly points to a page
that no longer exists. The correct URL is https://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html.
[2018-06-27] The announcement email for FreeBSD 11.2
incorrectly states the ocs_fw(4) driver
had been added; this should have stated
ocs_fc(4).
[2018-06-28] An issue had been reported after the
release of FreeBSD 11.2 with x11/nvidia-driver installed from
the upstream package mirrors via pkg(8).
Building x11/nvidia-driver from
the ports(7) collection has been reported to resolve
the issue.
See PR 228536 for more information.
