1 | KERNEL SOURCE: |
2 | ============== | |
3 | ||
4 | We currently use the Ubuntu kernel sources, available from: | |
5 | ||
6 | http://kernel.ubuntu.com/git/ubuntu/ubuntu-vivid.git | |
7 | ||
8 | ||
9 | Additional/Updated Modules: | |
10 | --------------------------- | |
11 | ||
12 | - include latest ixgbe driver from intel/sourceforge | |
13 | ||
14 | - include latest igb driver from intel/sourceforge | |

16 | # Note: hpsa does not compile with kernel 3.19.8 |
17 | #- include latest HPSA driver (HP Smart Array) | |
18 | # | |
19 | # * http://sourceforge.net/projects/cciss/ | |

20 | |
21 | - include native OpenZFS filesystem kernel modules for Linux | |
22 | ||
23 | * https://github.com/zfsonlinux/ | |
24 | ||
25 | For licensing questions, see: http://open-zfs.org/wiki/Talk:FAQ | |
26 | ||
27 | - include latest DRBD 9 driver, see http://drbd.linbit.com/home/what-is-drbd/ | |
28 | ||
29 | ||
30 | FIRMWARE: | |
31 | ========= | |
32 | ||
33 | We create our own firmware package, which includes the firmware for | |
34 | all proxmox-ve kernels. So far this include | |
35 | ||
36 | pve-kernel-2.6.18 | |
37 | pve-kernel-2.6.24 | |
38 | pve-kernel-2.6.32 | |
39 | pve-kernel-3.10.0 | |
40 | pve-kernel-3.19.0 | |
41 | ||
42 | We use 'find-firmware.pl' to extract lists of required firmeware | |
43 | files. The script 'assemble-firmware.pl' is used to read those lists | |
44 | and copy the files from various source directory into a target | |
45 | directory. | |
46 | ||
47 | We do not include firmeware for some wireless HW when there is a | |
48 | separate debian package for that, for example: | |
49 | ||
50 | zd1211-firmware | |
51 | atmel-firmware | |
52 | bluez-firmware | |
53 | ||
54 | ||
55 | PATCHES: | |
56 | -------- | |
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 | ||
65 | ||
66 | Additional information | |
67 | ---------------------- | |
68 | ||
69 | We use the default configuration provided by Ubuntu, and apply | |
70 | the following modification: | |
71 | ||
72 | see Makefile (PVE_CONFIG_OPTS) | |
73 | ||
74 | - enable CONFIG_CEPH_FS=m (request from user) | |
75 | ||
76 | - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection | |
77 | problems (udev, undate-initramfs hav serious problems without that) | |
78 | ||
79 | CONFIG_BLK_DEV_SD=y | |
80 | CONFIG_BLK_DEV_SR=y | |
81 | CONFIG_BLK_DEV_DM=y | |
82 | ||
83 | - compile NBD and RBD modules | |
84 | CONFIG_BLK_DEV_NBD=m | |
85 | CONFIG_BLK_DEV_RBD=m | |
86 | ||
87 | - set LOOP_MIN_COUNT to 8 (debian defaults) | |
88 | CONFIG_BLK_DEV_LOOP_MIN_COUNT=8 | |
89 | ||
90 | - disable module signatures (CONFIG_MODULE_SIG) | |
91 | ||
92 | - enable IBM JFS file system | |
93 | ||
94 | This is disabled in RHEL kernel for no real reason, so we enable | |
95 | it as requested by users (bug #64) | |
96 | ||
97 | - enable apple HFS and HFSPLUS | |
98 | ||
99 | This is disabled in RHEL kernel for no real reason, so we enable | |
100 | it as requested by users | |
101 | ||
102 | - enable CONFIG_BCACHE=m (requested by user) | |
103 | ||
104 | - enable CONFIG_BRIDGE=y | |
105 | ||
106 | Else we get warnings on boot, that | |
107 | net.bridge.bridge-nf-call-iptables is an unknown key | |
108 | ||
109 | - enable CONFIG_DEFAULT_SECURITY_APPARMOR | |
110 | ||
111 | We need this for lxc | |
112 | ||
113 | - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y | |
114 | ||
115 | because if not set, it can give some dynamic memory or cpu frequencies | |
116 | change, and vms can crash (mainly windows guest). | |
117 | ||
118 | see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273 | |
119 | ||
120 | - use 'deadline' as default scheduler | |
121 | ||
122 | This is the suggested setting for KVM. We also measure bad fsync | |
123 | performance with ext4 and cfq. | |
124 | ||
feaffad1 DM |
125 | - disable CONFIG_INPUT_EVBUG |
126 | ||
127 | Module evbug is not blacklisted on debian, so we simply disable it | |
128 | to avoid key-event logs (which is a big security problem) | |
129 | ||

130 | Testing final kernel with kvm |
131 | ----------------------------- | |
132 | ||
133 | kvm -kernel data/boot/vmlinuz-3.19.8-1-pve -initrd initrd.img-3.19.8-1-pve -append "vga=791 video=vesafb:ywrap,mtrr" /dev/zero | |
