   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 FIRMWARE:
  28 =========
  29
  30 We create our own firmware package, which includes the firmware for
  31 all proxmox-ve kernels. So far this include
  32
  33 pve-kernel-2.6.18
  34 pve-kernel-2.6.24
  35 pve-kernel-2.6.32
  36 pve-kernel-2.6.35
  37
  38 We use 'find-firmware.pl' to extract lists of required firmeware
  39 files.  The script 'assemble-firmware.pl' is used to read those lists
  40 and copy the files from various source directory into a target
  41 directory.
  42
  43 We do not include firmeware for some wireless HW when there is a
  44 separate debian package for that, for example:
  45
  46 zd1211-firmware
  47 atmel-firmware
  48 bluez-firmware

  51 PATCHES:
  52 --------
  53
  54  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  55
  56  bridge-patch.diff: Avoid bridge problems with changing MAC
  57   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  58
  59   Behaviour after 2.6.27 has changed slighly - after setting mac address
  60   of bridge device, then address won't change. So we could omit
  61   that patch, requiring to set hwaddress in /etc/network/interfaces.

  64 Additional information
  65 ----------------------
  66
  67 We use the default configuration provided by openvz, and apply
  68 the following modification:
  69
  70 see config-2.6.32.diff
  71
  72 - enable bootsplash
  73         CONFIG_FB_VESA=y
  74         CONFIG_FRAMEBUFFER_CONSOLE=Y
  75         CONFIG_BOOTSPLASH=y
  76
  77 - disable CONFIG_DEBUG_INFO
  78
  79 - disable CONFIG_PRINTK_TIME
  80
  81 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  82   problems (udev, undate-initramfs hav serious problems without that)
  83
  84          CONFIG_BLK_DEV_SD=y
  85          CONFIG_BLK_DEV_SR=y
  86          CONFIG_BLK_DEV_DM=y
  87
  88 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
  89
  90 - enable usbip (this is also enable on debian kernels)
  91
  92          CONFIG_USB_IP_COMMON=m
  93          CONFIG_USB_IP_VHCI_HCD=m
  94          CONFIG_USB_IP_HOST=m
  95
  96 - enable IBM JFS file system
  97
  98   This is disabled in RHEL kernel for no real reason, so we enable
  99   it as requested by users (bug #64)
 100
 101 - enable apple HFS and HFSPLUS
 102
 103   This is disabled in RHEL kernel for no real reason, so we enable
 104   it as requested by users
 105
 106 - enable CONFIG_BRIDGE=y
 107
 108   Else we get warnings on boot, that
 109   net.bridge.bridge-nf-call-iptables is an unknown key
 110
 111 Testing final kernel with kvm
 112 -----------------------------
 113
 114 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
