   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 FIRMWARE:
  30 =========
  31
  32 We create our own firmware package, which includes the firmware for
  33 all proxmox-ve kernels. So far this include
  34
  35 pve-kernel-2.6.18
  36 pve-kernel-2.6.24
  37 pve-kernel-2.6.32
  38 pve-kernel-2.6.35
  39
  40 We use 'find-firmware.pl' to extract lists of required firmeware
  41 files.  The script 'assemble-firmware.pl' is used to read those lists
  42 and copy the files from various source directory into a target
  43 directory.
  44
  45 We do not include firmeware for some wireless HW when there is a
  46 separate debian package for that, for example:
  47
  48 zd1211-firmware
  49 atmel-firmware
  50 bluez-firmware
  51
  52
  53 PATCHES:
  54 --------
  55
  56  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  57
  58  bridge-patch.diff: Avoid bridge problems with changing MAC
  59   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  60
  61   Behaviour after 2.6.27 has changed slighly - after setting mac address
  62   of bridge device, then address won't change. So we could omit
  63   that patch, requiring to set hwaddress in /etc/network/interfaces.
  64

  66 Additional information
  67 ----------------------
  68
  69 We use the default configuration provided by openvz, and apply
  70 the following modification:
  71
  72 see config-2.6.32.diff
  73
  74 - enable bootsplash
  75         CONFIG_FB_VESA=y
  76         CONFIG_FRAMEBUFFER_CONSOLE=Y
  77         CONFIG_BOOTSPLASH=y
  78
  79 - disable CONFIG_DEBUG_INFO
  80
  81 - disable CONFIG_PRINTK_TIME
  82
  83 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  84   problems (udev, undate-initramfs hav serious problems without that)
  85
  86          CONFIG_BLK_DEV_SD=y
  87          CONFIG_BLK_DEV_SR=y
  88          CONFIG_BLK_DEV_DM=y
  89
  90 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
  91
  92 - enable usbip (this is also enable on debian kernels)
  93
  94          CONFIG_USB_IP_COMMON=m
  95          CONFIG_USB_IP_VHCI_HCD=m
  96          CONFIG_USB_IP_HOST=m
  97
  98 - enable IBM JFS file system
  99
 100   This is disabled in RHEL kernel for no real reason, so we enable
 101   it as requested by users (bug #64)
 102
 103 - enable apple HFS and HFSPLUS
 104
 105   This is disabled in RHEL kernel for no real reason, so we enable
 106   it as requested by users
 107
 108 - enable CONFIG_BRIDGE=y
 109
 110   Else we get warnings on boot, that
 111   net.bridge.bridge-nf-call-iptables is an unknown key
 112
 113 - disable CONFIG_BRIDGE_IGMP_SNOOPING
 114
 115   To avoid problems with multicasting. Various users reported
 116   multipath problems, which can be avoided by turning off IGMP
 117   snooping.
 118
 119 - use 'deadline' as default scheduler
 120
 121   This is the suggested setting for KVM. We also measure bad fsync
 122   performance with ext4 and cfq.
 123
 124 Testing final kernel with kvm
 125 -----------------------------
 126
 127 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
