KERNEL SOURCE:
|
|
==============
|
|
|
|
We currently use the Ubuntu kernel sources, available from:
|
|
|
|
http://kernel.ubuntu.com/git/ubuntu/ubuntu-xenial.git/
|
|
|
|
Ubuntu will maintain those kernels till:
|
|
|
|
https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable
|
|
|
|
|
|
Additional/Updated Modules:
|
|
---------------------------
|
|
|
|
- include latest e1000e driver from intel/sourceforge
|
|
|
|
- include latest ixgbe driver from intel/sourceforge
|
|
|
|
- include latest igb driver from intel/sourceforge
|
|
|
|
# Note: hpsa does not compile with kernel 3.19.8
|
|
#- include latest HPSA driver (HP Smart Array)
|
|
#
|
|
# * http://sourceforge.net/projects/cciss/
|
|
|
|
- include native OpenZFS filesystem kernel modules for Linux
|
|
|
|
* https://github.com/zfsonlinux/
|
|
|
|
For licensing questions, see: http://open-zfs.org/wiki/Talk:FAQ
|
|
|
|
- include latest DRBD 9 driver, see http://drbd.linbit.com/home/what-is-drbd/
|
|
|
|
|
|
FIRMWARE:
|
|
=========
|
|
|
|
We create our own firmware package, which includes the firmware for
|
|
all proxmox-ve kernels. So far this include
|
|
|
|
pve-kernel-2.6.18
|
|
pve-kernel-2.6.24
|
|
pve-kernel-2.6.32
|
|
pve-kernel-3.10.0
|
|
pve-kernel-3.19.0
|
|
|
|
We use 'find-firmware.pl' to extract lists of required firmeware
|
|
files. The script 'assemble-firmware.pl' is used to read those lists
|
|
and copy the files from various source directory into a target
|
|
directory.
|
|
|
|
We do not include firmeware for some wireless HW when there is a
|
|
separate debian package for that, for example:
|
|
|
|
zd1211-firmware
|
|
atmel-firmware
|
|
bluez-firmware
|
|
|
|
|
|
PATCHES:
|
|
--------
|
|
|
|
bridge-patch.diff: Avoid bridge problems with changing MAC
|
|
see also: http://forum.openvz.org/index.php?t=msg&th=5291
|
|
|
|
Behaviour after 2.6.27 has changed slighly - after setting mac address
|
|
of bridge device, then address won't change. So we could omit
|
|
that patch, requiring to set hwaddress in /etc/network/interfaces.
|
|
|
|
Watchdog blacklist
|
|
------------------
|
|
|
|
By default, all watchdog modules are black-listed because it is totally undefined
|
|
which device is actually used for /dev/watchdog.
|
|
We ship this list in /lib/modprobe.d/blacklist_pve-kernel-<VERSION>.conf
|
|
The user typically edit /etc/modules to enable a specific watchdog device.
|
|
|
|
Additional information
|
|
----------------------
|
|
|
|
We use the default configuration provided by Ubuntu, and apply
|
|
the following modification:
|
|
|
|
see Makefile (PVE_CONFIG_OPTS)
|
|
|
|
- enable CONFIG_CEPH_FS=m (request from user)
|
|
|
|
- enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
|
|
problems (udev, undate-initramfs have serious problems without that)
|
|
|
|
CONFIG_BLK_DEV_SD=y
|
|
CONFIG_BLK_DEV_SR=y
|
|
CONFIG_BLK_DEV_DM=y
|
|
|
|
- add workaround for Debian bug #807000 (see
|
|
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=807000)
|
|
|
|
CONFIG_BLK_DEV_NVME=y
|
|
|
|
- compile NBD and RBD modules
|
|
CONFIG_BLK_DEV_NBD=m
|
|
CONFIG_BLK_DEV_RBD=m
|
|
|
|
- set LOOP_MIN_COUNT to 8 (debian defaults)
|
|
CONFIG_BLK_DEV_LOOP_MIN_COUNT=8
|
|
|
|
- disable module signatures (CONFIG_MODULE_SIG)
|
|
|
|
- enable IBM JFS file system
|
|
|
|
This is disabled in RHEL kernel for no real reason, so we enable
|
|
it as requested by users (bug #64)
|
|
|
|
- enable apple HFS and HFSPLUS
|
|
|
|
This is disabled in RHEL kernel for no real reason, so we enable
|
|
it as requested by users
|
|
|
|
- enable CONFIG_BCACHE=m (requested by user)
|
|
|
|
- enable CONFIG_BRIDGE=y
|
|
|
|
Else we get warnings on boot, that
|
|
net.bridge.bridge-nf-call-iptables is an unknown key
|
|
|
|
- enable CONFIG_DEFAULT_SECURITY_APPARMOR
|
|
|
|
We need this for lxc
|
|
|
|
- set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
|
|
|
|
because if not set, it can give some dynamic memory or cpu frequencies
|
|
change, and vms can crash (mainly windows guest).
|
|
|
|
see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273
|
|
|
|
- use 'deadline' as default scheduler
|
|
|
|
This is the suggested setting for KVM. We also measure bad fsync
|
|
performance with ext4 and cfq.
|
|
|
|
- disable CONFIG_INPUT_EVBUG
|
|
|
|
Module evbug is not blacklisted on debian, so we simply disable it
|
|
to avoid key-event logs (which is a big security problem)
|
|
|
|
Testing final kernel with kvm
|
|
-----------------------------
|
|
|
|
kvm -kernel data/boot/vmlinuz-3.19.8-1-pve -initrd initrd.img-3.19.8-1-pve -append "vga=791 video=vesafb:ywrap,mtrr" /dev/zero
