FreeBSD/i386 10.3-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�10.3-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 svn://svn.freebsd.org/base/releng/10.2 /usr/src
Build the kernel-toolchain
required
to rebuild the kernel:
#
make -C /usr/src kernel-toolchain
Next, 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/repos
If using csh(1):
#
setenv REPOS_DIR /dist/packages/repos
Keep 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-server
xorg
gnome3
[...]
An issue was discovered where the netstat(1)
-s
option will cause a segmentation fault
on systems with IPSEC
compiled into the
kernel. The issue was resolved in the
stable/10
branch, and an Errata Notice is
planned after 10.3-RELEASE is released.
[2015-08-19] Resolved as FreeBSD-EN-15:12.
An issue was discovered that causes make(1) to generate noisy output when doing source-based upgrades from FreeBSD 9.3 and earlier. The issue was reported in PR 202277, and after investigation and determining the issue does not cause source-based upgrades to fail, a post-release Errata Notice is planned.
[2015-08-19] Resolved as FreeBSD-EN-15:11.
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
.
[2015-08-16] An error was discovered in the release
notes for FreeBSD 10.3-RELEASE regarding the
drm
device driver. The entry for r282199
states the driver was updated to match the version Linux�
3.8.13 version, however the entry should have noted the
change affects device-independent code, and does not bring
the drm
driver fully in line with the
stated Linux� version.
