   1 KERNEL SOURCE:
   2 ==============
   3
   4 We use the OpenVZ Kernel sources, available from:
   5
   6 http://download.openvz.org/kernel/branches/rhel6-2.6.32/
   7
   8
   9 Additional/Updated Modules:
  10 ---------------------------
  11
  12 - we use bootsplash to display the boot logo.
  13
  14 - include latest AoE driver (http://support.coraid.com/support/linux)
  15
  16 - include latest ixgbe driver from intel/sourceforge
  17
  18 - include latest igb driver from intel/sourceforge
  19
  20 - include latest e1000e driver from intel/sourceforge
  21
  22 - include latest Broadcom bnx2 drivers
  23
  24   * original file linux-7.4.27.zip contains
  25     netxtreme2-7.4.27.tar.gz (added to repository)
  26
  27 - include latest Adaptec aacraid driver
  28
  29   * http://download.adaptec.com/raid/aac/linux/aacraid-linux-src-1.2.1-30200.tgz
  30
  31 FIRMWARE:
  32 =========
  33
  34 We create our own firmware package, which includes the firmware for
  35 all proxmox-ve kernels. So far this include
  36
  37 pve-kernel-2.6.18
  38 pve-kernel-2.6.24
  39 pve-kernel-2.6.32
  40 pve-kernel-2.6.35
  41
  42 We use 'find-firmware.pl' to extract lists of required firmeware
  43 files.  The script 'assemble-firmware.pl' is used to read those lists
  44 and copy the files from various source directory into a target
  45 directory.
  46
  47 We do not include firmeware for some wireless HW when there is a
  48 separate debian package for that, for example:
  49
  50 zd1211-firmware
  51 atmel-firmware
  52 bluez-firmware
  53
  54
  55 PATCHES:
  56 --------
  57
  58  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  59
  60  bridge-patch.diff: Avoid bridge problems with changing MAC
  61   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  62
  63   Behaviour after 2.6.27 has changed slighly - after setting mac address
  64   of bridge device, then address won't change. So we could omit
  65   that patch, requiring to set hwaddress in /etc/network/interfaces.

  68 Additional information
  69 ----------------------
  70
  71 We use the default configuration provided by openvz, and apply
  72 the following modification:
  73
  74 see config-2.6.32.diff
  75
  76 - enable bootsplash
  77         CONFIG_FB_VESA=y
  78         CONFIG_FRAMEBUFFER_CONSOLE=Y
  79         CONFIG_BOOTSPLASH=y
  80
  81 - disable CONFIG_DEBUG_INFO
  82
  83 - disable CONFIG_PRINTK_TIME
  84
  85 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  86   problems (udev, undate-initramfs hav serious problems without that)
  87
  88          CONFIG_BLK_DEV_SD=y
  89          CONFIG_BLK_DEV_SR=y
  90          CONFIG_BLK_DEV_DM=y
  91
  92 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
  93
  94 - enable usbip (this is also enable on debian kernels)
  95
  96          CONFIG_USB_IP_COMMON=m
  97          CONFIG_USB_IP_VHCI_HCD=m
  98          CONFIG_USB_IP_HOST=m
  99
 100 - enable IBM JFS file system
 101
 102   This is disabled in RHEL kernel for no real reason, so we enable
 103   it as requested by users (bug #64)
 104
 105 - enable apple HFS and HFSPLUS
 106
 107   This is disabled in RHEL kernel for no real reason, so we enable
 108   it as requested by users
 109
 110 - enable CONFIG_BRIDGE=y
 111
 112   Else we get warnings on boot, that
 113   net.bridge.bridge-nf-call-iptables is an unknown key
 114
 115 - disable CONFIG_BRIDGE_IGMP_SNOOPING
 116
 117   To avoid problems with multicasting. Various users reported
 118   multipath problems, which can be avoided by turning off IGMP
 119   snooping.
 120
 121 - use 'deadline' as default scheduler
 122
 123   This is the suggested setting for KVM. We also measure bad fsync
 124   performance with ext4 and cfq.
 125
 126 Testing final kernel with kvm
 127 -----------------------------
 128
 129 kvm -kernel data/boot/vmlinuz-2.6.32-6-pve -initrd initrd.img-2.6.32-6-pve -append "vga=791 video=vesafb:ywrap,mtrr splash=silent" /dev/zero
