  55 FIRMWARE:
  56 =========
  57
  58 We create our own firmware package, which includes the firmware for
  59 all proxmox-ve kernels. So far this include
  60
  61 pve-kernel-2.6.18
  62 pve-kernel-2.6.24
  63 pve-kernel-2.6.32
  64 pve-kernel-2.6.35
  65
  66 We use 'find-firmware.pl' to extract lists of required firmeware
  67 files.  The script 'assemble-firmware.pl' is used to read those lists
  68 and copy the files from various source directory into a target
  69 directory.
  70
  71 We do not include firmeware for some wireless HW when there is a
  72 separate debian package for that, for example:
  73
  74 zd1211-firmware
  75 atmel-firmware
  76 bluez-firmware
  77
  78
  79 PATCHES:
  80 --------
  81
  82  bootsplash-3.1.9-2.6.31-rh.patch: bootsplash patch
  83
  84  bridge-patch.diff: Avoid bridge problems with changing MAC
  85   see also: http://forum.openvz.org/index.php?t=msg&th=5291
  86
  87   Behaviour after 2.6.27 has changed slighly - after setting mac address
  88   of bridge device, then address won't change. So we could omit
  89   that patch, requiring to set hwaddress in /etc/network/interfaces.
  90
  91
  92 Additional information
  93 ----------------------
  94
  95 We use the default configuration provided by openvz, and apply
  96 the following modification:
  97
  98 see config-2.6.32.diff
  99
 100 - enable bootsplash
 101         CONFIG_FB_VESA=y
 102         CONFIG_FRAMEBUFFER_CONSOLE=Y
 103         CONFIG_BOOTSPLASH=y
 104
 105 - disable CONFIG_DEBUG_INFO
 106
 107 - disable CONFIG_PRINTK_TIME
 108
 109 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
 110   problems (udev, undate-initramfs hav serious problems without that)
 111
 112          CONFIG_BLK_DEV_SD=y
 113          CONFIG_BLK_DEV_SR=y
 114          CONFIG_BLK_DEV_DM=y
 115
 116 - disable module signatures (CONFIG_MODULE_SIG, CONFIG_CRYPTO_SIGNATURE)
 117
 118 - enable usbip (this is also enable on debian kernels)
 119
 120          CONFIG_USB_IP_COMMON=m
 121          CONFIG_USB_IP_VHCI_HCD=m
 122          CONFIG_USB_IP_HOST=m
 123
 124 - enable IBM JFS file system
 125
 126   This is disabled in RHEL kernel for no real reason, so we enable
 127   it as requested by users (bug #64)
 128
 129 - enable apple HFS and HFSPLUS
 130
 131   This is disabled in RHEL kernel for no real reason, so we enable
 132   it as requested by users
 133
 134 - enable CONFIG_BRIDGE=y
 135
 136   Else we get warnings on boot, that
 137   net.bridge.bridge-nf-call-iptables is an unknown key
 138
 139 - disable CONFIG_BRIDGE_IGMP_SNOOPING
 140
 141   To avoid problems with multicasting. Various users reported
 142   multipath problems, which can be avoided by turning off IGMP
 143   snooping.
 144
 145 - use 'deadline' as default scheduler
 146
 147   This is the suggested setting for KVM. We also measure bad fsync
 148   performance with ext4 and cfq.
 149
 150 - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
 151
 152   because if not set, it can give some dynamic memory or cpu frequencies
 153   change, and vms can crash (mainly windows guest).
 154
 155   see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273

 157 Testing final kernel with kvm
 158 -----------------------------
 159
 160 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
