   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 - include latest megaraid_sas driver
  32
  33   *  http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/MR_Linux_Driver_6.600.18.00.tgz
  34
  35   (extract source file megaraid_sas-06.600.18.00-src.tar.gz)
  36
  37 FIRMWARE:
  38 =========
  39
  40 We create our own firmware package, which includes the firmware for
  41 all proxmox-ve kernels. So far this include
  42
  43 pve-kernel-2.6.18
  44 pve-kernel-2.6.24
  45 pve-kernel-2.6.32
  46 pve-kernel-2.6.35
  47
  48 We use 'find-firmware.pl' to extract lists of required firmeware
  49 files.  The script 'assemble-firmware.pl' is used to read those lists
  50 and copy the files from various source directory into a target
  51 directory.
  52
  53 We do not include firmeware for some wireless HW when there is a
  54 separate debian package for that, for example:
  55
  56 zd1211-firmware
  57 atmel-firmware
  58 bluez-firmware
  59
  60
  61 PATCHES:
  62 --------
  63
  64  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  65
  66  bridge-patch.diff: Avoid bridge problems with changing MAC
  67   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  68
  69   Behaviour after 2.6.27 has changed slighly - after setting mac address
  70   of bridge device, then address won't change. So we could omit
  71   that patch, requiring to set hwaddress in /etc/network/interfaces.
  72
  73
  74 Additional information
  75 ----------------------
  76
  77 We use the default configuration provided by openvz, and apply
  78 the following modification:
  79
  80 see config-2.6.32.diff
  81
  82 - enable bootsplash
  83         CONFIG_FB_VESA=y
  84         CONFIG_FRAMEBUFFER_CONSOLE=Y
  85         CONFIG_BOOTSPLASH=y
  86
  87 - disable CONFIG_DEBUG_INFO
  88
  89 - disable CONFIG_PRINTK_TIME
  90
  91 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  92   problems (udev, undate-initramfs hav serious problems without that)
  93
  94          CONFIG_BLK_DEV_SD=y
  95          CONFIG_BLK_DEV_SR=y
  96          CONFIG_BLK_DEV_DM=y
  97
  98 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
  99
 100 - enable usbip (this is also enable on debian kernels)
 101
 102          CONFIG_USB_IP_COMMON=m
 103          CONFIG_USB_IP_VHCI_HCD=m
 104          CONFIG_USB_IP_HOST=m
 105
 106 - enable IBM JFS file system
 107
 108   This is disabled in RHEL kernel for no real reason, so we enable
 109   it as requested by users (bug #64)
 110
 111 - enable apple HFS and HFSPLUS
 112
 113   This is disabled in RHEL kernel for no real reason, so we enable
 114   it as requested by users
 115
 116 - enable CONFIG_BRIDGE=y
 117
 118   Else we get warnings on boot, that
 119   net.bridge.bridge-nf-call-iptables is an unknown key
 120
 121 - disable CONFIG_BRIDGE_IGMP_SNOOPING
 122
 123   To avoid problems with multicasting. Various users reported
 124   multipath problems, which can be avoided by turning off IGMP
 125   snooping.
 126
 127 - use 'deadline' as default scheduler
 128
 129   This is the suggested setting for KVM. We also measure bad fsync
 130   performance with ext4 and cfq.
 131
 132 Testing final kernel with kvm
 133 -----------------------------
 134
 135 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
