2 - new --hvm-nic-type and --hvm-disk-type flags to control the type of disk
3 exported to fully virtualized instances.
4 - instance auto_balance flag, set by default. If turned off it will avoid
5 warnings on cluster verify if there is not enough memory to fail over an
6 instance. in the future it will prevent automatically failing it over when
8 - batcher tool for instance creation, see /tools/README.batcher
9 - gnt-instance reinstall --select-os to interactively select a new operating
10 system when reinstalling an instance.
11 - when changing the memory amount on instance modify a check has been added
12 that the instance will be able to start. also warnings are emitted if the
13 instance will not be able to fail over, if auto_balance is true.
15 - sync fields between instance list/modify/add/import
18 - note: the allowed size and number of tags per object were reduced
19 - fix a bug in “gnt-cluster verify” with inconsistent volume groups
20 - fixed twisted 8.x compatibility
21 - fixed gnt-instance replace-disks with iallocator
22 - add TCP keepalives on twisted connections to detect restarted nodes
23 - disk increase support, see “gnt-instance grow-disk”
24 - implement bulk node/instance query for RAPI
25 - add tags in node/instance listing (optional)
26 - experimental migration (and live migration) support, read the man
27 page for “gnt-instance migrate”
28 - the ganeti-watcher logs are now timestamped, and the watcher also
29 has some small improvements in handling its state file
32 - Experimental readonly, REST-based remote API implementation; automatically
33 started on master node, TCP port 5080, if enabled by --enable-rapi
34 parameter to configure script.
35 - Instance allocator support. Add and import instance accept a --iallocator
36 parameter, and call that instance allocator to decide which node to use for
37 the instance. The iallocator document describes what's expected from an
39 - gnt-cluster verify N+1 memory redundancy checks: Unless passed the
40 --no-nplus1-mem option gnt-cluster verify now checks that if a node is lost
41 there is still enough memory to fail over the instances that reside on it.
42 - gnt-cluster verify hooks: it is now possible to add post-hooks to
43 gnt-cluster verify, to check for site-specific compliance. All the hooks
44 will run, and their output, if any, will be displayed. Any failing hook
45 will make the verification return an error value.
46 - gnt-cluster verify now checks that its peers are reachable on the primary
47 and secondary interfaces
48 - gnt-node add now supports the --readd option, to readd a node that is still
49 declared as part of the cluster and has failed.
50 - gnt-* list commands now accept a new -o +field way of specifying output
51 fields, that just adds the chosen fields to the default ones.
52 - gnt-backup now has a new "remove" command to delete an existing export from
54 - New per-instance parameters hvm_acpi, hvm_pae and hvm_cdrom_image_path have
55 been added. Using them you can enable/disable acpi and pae support, and
56 specify a path for a cd image to be exported to the instance. These
57 parameters as the name suggest only work on HVM clusters.
58 - When upgrading an HVM cluster to Ganeti 1.2.4, the values for ACPI and PAE
59 support will be set to the previously hardcoded values, but the (previously
60 hardcoded) path to the CDROM ISO image will be unset and if required, needs
61 to be set manually with gnt-instance modify after the upgrade..
62 - The address to which an instance's VNC console is bound is now selectable
63 per-instance, rather than being cluster wide. Of course this only applies
64 to instances controlled via VNC, so currently just applies to HVM clusters.
67 - more tweaks to the disk activation code (especially helpful for DRBD)
68 - change the default ‘gnt-instance list’ output format, now there is
69 one combined status field (see the manpage for the exact values this
71 - some more fixes for the mac export to hooks change
72 - make Ganeti not break with DRBD 8.2.x (which changed the version
73 format in /proc/drbd) (issue 24)
74 - add an upgrade tool from ‘remote_raid1’ disk template to ‘drbd’ disk
75 template, allowing migration from DRBD0.7+MD to DRBD8
78 - fix ‘gnt-instance modify’ breakage introduced in 1.2.1 with the HVM
80 - add command aliases infrastructure and a few aliases
81 - allow listing of VCPUs in the gnt-instance list and improve the man
82 pages and the --help option of gnt-node/gnt-instance list
83 - fix gnt-backup list with down nodes (issue 21)
84 - change the tools location (move from $pkgdatadir to
86 - fix the dist archive and add a check for including svn/git files in
88 - some developer-related changes: improve the burnin and the QA
89 suite, add an upload script for testing during development
92 - experimental HVM support, read the install document, section
93 "Initializing the cluster"
94 - allow for the PVM hypervisor per-instance kernel and initrd paths
95 - add a new command ‘gnt-cluster verify-disks’ which uses a new
96 algorithm to improve the reconnection of the DRBD pairs if the
97 device on the secondary node has gone away
98 - make logical volume code auto-activate LVs at disk activation time
99 - slightly improve the speed of activating disks
100 - allow specification of the MAC address at instance creation time,
101 and changing it later via ‘gnt-instance modify’
102 - fix handling of external commands that generate lots of output on
104 - update documentation with regard to minimum version of DRBD8
108 - Log the ‘xm create’ output to the node daemon log on failure (to
109 help diagnosing the error)
110 - In debug mode, log all external commands output if failed to the
112 - Change parsing of lvm commands to ignore stderr
115 - Another round of updates to the DRBD 8 code to deal with more
116 failures in the replace secondary node operation
117 - Some more logging of failures in disk operations (lvm, drbd)
118 - A few documentation updates
122 - Change configuration file format from Python's Pickle to JSON.
123 Upgrading is possible using the cfgupgrade utility.
124 - Add support for DRBD 8.0 (new disk template `drbd`) which allows for
125 faster replace disks and is more stable (DRBD 8 has many
126 improvements compared to DRBD 0.7)
127 - Added command line tags support (see man pages for gnt-instance,
128 gnt-node, gnt-cluster)
129 - Added instance rename support
130 - Added multi-instance startup/shutdown
131 - Added cluster rename support
132 - Added `gnt-node evacuate` to simplify some node operations
133 - Added instance reboot operation that can speedup reboot as compared
135 - Soften the requirement that hostnames are in FQDN format
136 - The ganeti-watcher now activates drbd pairs after secondary node
138 - Removed dependency on debian's patched fping that uses the
139 non-standard -S option
140 - Now the OS definitions are searched for in multiple, configurable
141 paths (easier for distros to package)
142 - Some changes to the hooks infrastructure (especially the new
143 post-configuration update hook)
144 - Other small bugfixes
