   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

   9 Additional/Updated Modules:
  10 ---------------------------
  11
  12 - we use bootsplash to display the boot logo.

  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 - include Highpoint RocketRAID 272X driver
  38
  39   * http://www.highpoint-tech.com/BIOS_Driver/rr272x_1x/linux_1.5/RR272x_1x-Linux-Src-v1.5-130325-0732.tar.gz

  41 FIRMWARE:
  42 =========
  43
  44 We create our own firmware package, which includes the firmware for
  45 all proxmox-ve kernels. So far this include
  46
  47 pve-kernel-2.6.18
  48 pve-kernel-2.6.24
  49 pve-kernel-2.6.32
  50 pve-kernel-2.6.35
  51
  52 We use 'find-firmware.pl' to extract lists of required firmeware
  53 files.  The script 'assemble-firmware.pl' is used to read those lists
  54 and copy the files from various source directory into a target
  55 directory.
  56
  57 We do not include firmeware for some wireless HW when there is a
  58 separate debian package for that, for example:
  59
  60 zd1211-firmware
  61 atmel-firmware
  62 bluez-firmware
  63
  64
  65 PATCHES:
  66 --------
  67
  68  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  69
  70  bridge-patch.diff: Avoid bridge problems with changing MAC
  71   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  72
  73   Behaviour after 2.6.27 has changed slighly - after setting mac address
  74   of bridge device, then address won't change. So we could omit
  75   that patch, requiring to set hwaddress in /etc/network/interfaces.
  76

  78 Additional information
  79 ----------------------
  80
  81 We use the default configuration provided by openvz, and apply
  82 the following modification:
  83
  84 see config-2.6.32.diff
  85
  86 - enable bootsplash
  87         CONFIG_FB_VESA=y
  88         CONFIG_FRAMEBUFFER_CONSOLE=Y
  89         CONFIG_BOOTSPLASH=y
  90
  91 - disable CONFIG_DEBUG_INFO
  92
  93 - disable CONFIG_PRINTK_TIME
  94
  95 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
  96   problems (udev, undate-initramfs hav serious problems without that)
  97
  98          CONFIG_BLK_DEV_SD=y
  99          CONFIG_BLK_DEV_SR=y
 100          CONFIG_BLK_DEV_DM=y
 101
 102 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
 103
 104 - enable usbip (this is also enable on debian kernels)
 105
 106          CONFIG_USB_IP_COMMON=m
 107          CONFIG_USB_IP_VHCI_HCD=m
 108          CONFIG_USB_IP_HOST=m
 109
 110 - enable IBM JFS file system
 111
 112   This is disabled in RHEL kernel for no real reason, so we enable
 113   it as requested by users (bug #64)
 114
 115 - enable apple HFS and HFSPLUS
 116
 117   This is disabled in RHEL kernel for no real reason, so we enable
 118   it as requested by users
 119
 120 - enable CONFIG_BRIDGE=y
 121
 122   Else we get warnings on boot, that
 123   net.bridge.bridge-nf-call-iptables is an unknown key
 124
 125 - disable CONFIG_BRIDGE_IGMP_SNOOPING
 126
 127   To avoid problems with multicasting. Various users reported
 128   multipath problems, which can be avoided by turning off IGMP
 129   snooping.
 130
 131 - use 'deadline' as default scheduler
 132
 133   This is the suggested setting for KVM. We also measure bad fsync
 134   performance with ext4 and cfq.
 135
 136 Testing final kernel with kvm
 137 -----------------------------
 138
 139 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
