4 We use the CENTOS7/RHEL7 kernel sources, available from:
6 http://vault.centos.org/
9 Additional/Updated Modules:
10 ---------------------------
12 - include latest ixgbe driver from intel/sourceforge
14 - include latest igb driver from intel/sourceforge
16 - include latest e1000e driver from intel/sourceforge
18 include latest Broadcom bnx2 drivers: http://driverdownloads.qlogic.com/
20 * original file linux-7.11.05.zip contains
21 netxtreme2-7.11.05.tar.gz (added to repository)
23 - include latest Adaptec aacraid driver
25 * http://download.adaptec.com/raid/aac/linux/aacraid-linux-src-1.2.1-40300.tgz
27 - include latest ARECA RAID drivers
29 * http://www.areca.com.tw/support/s_linux/linux.htm
34 We create our own firmware package, which includes the firmware for
35 all proxmox-ve kernels. So far this include
43 We use 'find-firmware.pl' to extract lists of required firmeware
44 files. The script 'assemble-firmware.pl' is used to read those lists
45 and copy the files from various source directory into a target
48 We do not include firmeware for some wireless HW when there is a
49 separate debian package for that, for example:
59 bridge-patch.diff: Avoid bridge problems with changing MAC
60 see also: http://forum.openvz.org/index.php?t=msg&th=5291
62 Behaviour after 2.6.27 has changed slighly - after setting mac address
63 of bridge device, then address won't change. So we could omit
64 that patch, requiring to set hwaddress in /etc/network/interfaces.
67 Additional information
68 ----------------------
70 We use the default configuration provided by RHEL, and apply
71 the following modification:
73 see config-3.10.0.diff
75 - enable CONFIG_CEPH_FS=m (request from user)
77 - enable common CONFIG_BLK_DEV_XXX to avoid hardware detection
78 problems (udev, undate-initramfs hav serious problems without that)
84 - compile NBD and RBD modules
88 - set LOOP_MIN_COUNT to 8 (debian defaults)
89 CONFIG_BLK_DEV_LOOP_MIN_COUNT=8
91 - disable module signatures (CONFIG_MODULE_SIG)
93 - enable IBM JFS file system
95 This is disabled in RHEL kernel for no real reason, so we enable
96 it as requested by users (bug #64)
98 - enable apple HFS and HFSPLUS
100 This is disabled in RHEL kernel for no real reason, so we enable
101 it as requested by users
103 - enable CONFIG_BCACHE=m (requested by user)
105 - enable CONFIG_BRIDGE=y
107 Else we get warnings on boot, that
108 net.bridge.bridge-nf-call-iptables is an unknown key
110 - disable CONFIG_DEFAULT_SECURITY_SELINUX
112 Use same SELINUX config as debian kernels (CONFIG_DEFAULT_SECURITY_DAC=y)
114 - set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
116 because if not set, it can give some dynamic memory or cpu frequencies
117 change, and vms can crash (mainly windows guest).
119 see http://forum.proxmox.com/threads/18238-Windows-7-x64-VMs-crashing-randomly-during-process-termination?p=93273#post93273
121 - set CONFIG_CC_STACKPROTECTOR_REGULAR=y
123 gcc on debian wheezy does not supportCONFIG_CC_STACKPROTECTOR_STRONG
125 # Note: enable now for testing
126 #- disable CONFIG_BRIDGE_IGMP_SNOOPING
128 # To avoid problems with multicasting. Various users reported
129 # multipath problems, which can be avoided by turning off IGMP
132 # deadline is default anyways now
133 #- use 'deadline' as default scheduler
135 # This is the suggested setting for KVM. We also measure bad fsync
136 # performance with ext4 and cfq.
138 Testing final kernel with kvm
