   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 FIRMWARE:
  23 =========
  24
  25 We create our own firmware package, which includes the firmware for
  26 all proxmox-ve kernels. So far this include
  27
  28 pve-kernel-2.6.18
  29 pve-kernel-2.6.24
  30 pve-kernel-2.6.32
  31 pve-kernel-2.6.35
  32
  33 We use 'find-firmware.pl' to extract lists of required firmeware
  34 files.  The script 'assemble-firmware.pl' is used to read those lists
  35 and copy the files from various source directory into a target
  36 directory.
  37
  38 We do not include firmeware for some wireless HW when there is a
  39 separate debian package for that, for example:
  40
  41 zd1211-firmware
  42 atmel-firmware
  43 bluez-firmware
  44
  45
  46 PATCHES:
  47 --------
  48
  49  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  50
  51  bridge-patch.diff: Avoid bridge problems with changing MAC
  52   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  53
  54   Behaviour after 2.6.27 has changed slighly - after setting mac address
  55   of bridge device, then address won't change. So we could omit
  56   that patch, requiring to set hwaddress in /etc/network/interfaces.

  59 Additional information
  60 ----------------------
  61
  62 We use the default configuration provided by openvz, and apply
  63 the following modification:
  64
  65 see config-2.6.32.diff
  66
  67 - enable bootsplash
  68         CONFIG_FB_VESA=y
  69         CONFIG_FRAMEBUFFER_CONSOLE=Y
  70         CONFIG_BOOTSPLASH=y
  71
  72 - disable CONFIG_DEBUG_INFO
  73
  74 - disable CONFIG_PRINTK_TIME
  75
  76 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  77   problems (udev, undate-initramfs hav serious problems without that)
  78
  79          CONFIG_BLK_DEV_SD=y
  80          CONFIG_BLK_DEV_SR=y
  81          CONFIG_BLK_DEV_DM=y
  82
  83 - disable CONFIG_RT_GROUP_SCHED to avoid corosync startup errors
  84
  85 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
  86
  87 - enable usbip (this is also enable on debian kernels)
  88
  89          CONFIG_USB_IP_COMMON=m
  90          CONFIG_USB_IP_VHCI_HCD=m
  91          CONFIG_USB_IP_HOST=m
  92
  93 - enable IBM JFS file system
  94
  95   This is disabled in RHEL kernel for no real reason, so we enable
  96   it as requested by users (bug #64)
  97
  98 - enable CONFIG_BRIDGE=y
  99
 100   Else we get warnings on boot, that
 101   net.bridge.bridge-nf-call-iptables is an unknown key
 102
 103 Testing final kernel with kvm
 104 -----------------------------
 105
 106 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
