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 | ||
901e6064 | 22 | - include latest Broadcom bnx2 drivers |
56a8d4f0 DM |
23 | |
24 | * original file linux-7.4.27.zip contains | |
25 | netxtreme2-7.4.27.tar.gz (added to repository) | |
26 | ||
901e6064 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. | |

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 | |
