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 | ||

| 13 | ||
| 14 | - include latest AoE driver (http://support.coraid.com/support/linux) | |
| 15 | ||
| 16 | - include latest ixgbe driver from intel/sourceforge | |
| 17 | ||

| 21 | ||
| 901e6064 | 22 | - include latest Broadcom bnx2 drivers |
| 56a8d4f0 DM |

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. | |

| 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 | ||
| e21b3827 DM |
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 | ||
| d9e10626 | 98 | - enable IBM JFS file system |
| 7e70f1cc DM |
99 | |
| 100 | This is disabled in RHEL kernel for no real reason, so we enable | |
| 101 | it as requested by users (bug #64) | |
| 1cfff965 | 102 | |
| d9e10626 DM |
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 | ||
| 2c0fe19a DM |
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 | ||
| e5c53408 DM |
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 | ||
| 43117d4e DM |
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. | |
| e5c53408 | 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 | |
