Add constants for a ping confd request
Signed-off-by: Guido Trotter <ultrotter@google.com>Reviewed-by: Iustin Pop <iustin@google.com>
Add a missing node role
Apart from being a master, a candidate, offline or drained, a node canhave one more state: none of those. Adding back the normal, nice,healthy "just" a node! :)
Add a common error code for confd
If we standardize common error codes, clients can make use of them toreact, rather than trying to parse error strings.
Constants: config directories cleanup
Use variables already defined.Introduce ganeti CONF_DIR.

confd.server.ConfdProcessor
A ConfdProcessor is the job processor for a confd query.It's responsible for all the processing, from unpacking it, verifyingit, to calculating the result.
Reply status constants for confd
These are valid values for the "status" field in objects.ConfdReply
constants for the confd daemon
Adding the various basic daemon constants for confd.
constants: confd node roles
confd will return the node role as an integer, which represents one ofthe mutually exclusive roles a node can be in.
constants: confd query types
Initially confd will support only two queries:
CONFD_REQ_NODE_ROLE_BYNAMEGiven a node name, return its role.
CONFD_REQ_NODE_PIP_BY_INSTANCE_IPGiven an instance ip, return its node primary ip.This rather weird query is the basis for ganeti nbma lookup....
ssconf.CheckMasterCandidate
This function checks that the current node is a master candidate, andterminates otherwise. It will be used upon ganeti-confd startup.

Collapse SSL key checking/overriding for daemons
Signed-off-by: Guido Trotter <ultrotter@google.com>
Collapse daemon's main function
With three ganeti daemons, and one or two more coming, the daemon's mainfunction started becoming too much cut&pasted code. Collapsing most ofit in a daemon.GenericMain function. Some more code could be collapsedbetween the two http-based daemons, but since the new daemons won't be...
Slightly abstract the daemon logfile lookup
The original LOG_<DAEMON_NAME> constants for daemon logfiles are gone.In their place there is a DAEMONS_LOGFILES dict, indexed by daemon name.
This is a minor change with the objective to uniform most of thedaemon's main() functions code, which is very similar one to the other....
Remove <DAEMON>_PID constants
The <DAEMON>_PID constants were created to reference a daemon pid file,but actually contain a daemon's name, because the various functions thatwork with pidfiles abstract the filename from the daemon namethemselves. Removing the constants and using the actual daemon name...
Move rapi to GetDaemonPort
Currently rapi is the only daemon which accepts a port option, ratherthan querying its own port from services, and failing back to thedefault if not found. Changing this to conform to what other daemons do.

Change GetNodeDaemonPort to GetDaemonPort in utils
GetNodeDaemonPort is used to lookup the node daemon port in the servicesfile, and if not found to return the default one. We make it a genericfunction, which accepts the daemon name in input, so that it can be used...
Merge branch 'next' into branch-2.1
Get rid of constants.RAPI_ENABLE
This constant is unused, except in qa. Removing it since it's always True.
This patch also removes the unused qa_rapi.PrintRemoteAPIWarningfunction, and removes a comment about temporary constants "until we havecluster parameters"....
noded: Abstract hard-coded sys.exit value
On machines without the ssl file noded exists '5'.Changing this to constants.EXIT_NOTCLUSTER.
Also utils.GetNodeDaemonPort hasn't risen errors.ConfigurationError fora while, so removing that try/except block....
Generate a shared HMAC key at cluster init time
This key is shared on all nodes (via cmdlib._RedistributeAncillaryFiles)and will be used for HMAC authentication of confd messages.
Merge commit 'origin/next' into branch-2.1
Conflicts: lib/cli.py: trivial extra empty line
job queue: fix loss of finalized opcode result
Currently, unclean master daemon shutdown overwrites all of a job'sopcode status and result with error/None. This is incorrect, since theany already finished opcode(s) should have their status and resultpreserved, and only not-yet-processed opcodes should be marked as...
Introduce OS api version 15
Also, since Ganeti 2.1 will be compatible with both 10 and 15, changethe OS_API_VERSION constant to be an OS_API_VERSIONS set, and update theplaces in the code that used that constat to use something else.
In particular: - in the qa for now we just create a fake version 10 OS...
Remove old invalid-os related functionality
We no longer need OS objects to be able to represent invalid OSes. Thiscleans up the code handling those cases.

Convert iallocator_runner rpc to new result style
This patch converts this rpc into the new style. Since the functionalready had some error handling, we remove this custom error reportingand replace it with our (new-style) result type. This allows significant...
nic parameters: constants
Introducing the constants used for implementing nic parameters inGaneti, according to the 2.1 design.
Change BEGR_DEFAULT to PP_DEFAULT
This way the same constant can represent the default profile also fornic, disk and OS parameters.
Add a lvm stripecount configure parameter
This patch adds a configure-time customizable parameter that will beused to enable stripped LVs. The default of the parameter is 3.
Merge branch 'branch-2.1' into feature/containers
Remove the HTS_COPY_VNC_PASSWORD constant/feature
Currently just for xen-hvm we copy the vnc password on node-add. Thiswill be changed for 2.1 with a more advanced gnt-cluster redist-conffunctionality which is going to be used by node-add as well.

Move more hypervisor strings into constants
This patch adds constants for the mouse and boot order strings; whilethere are still some issues remaining, we're trying to cleanup hardcodedstrings from the hypervisors.

Move HVM's device_model to a hypervisor parameter
This moves yet another hardcoded value to a hypervisor parameter. Iremoved the 64/32 difference as it doesn't seem valid to me - it's moreof a local site config rather than arch config.
Implement the KERNEL_PATH parameter for xen-hvm
For the xen-hvm hypervisor, the KERNEL_PATH parameter is needed buttoday is hardcoded to a constants in the xen hypervisor library (argh!).

Currently we use the HTS_USE_VNC constant only to copy the vnc passwordfile. While KVM uses vnc it currently has no password support, nor we'llbe on time making one for 2.0, so renaming the constant toHTS_COPY_VNC_PASSWORD and only putting Xen HVM in it. In the future...

Rename the device type constants
These are not HVM specific, so have been given an HT generic name.
s/HT_HVM_VNC_BASE_PORT/VNC_BASE_PORT/g
The VNC base port has nothing to do with HVM itself, and is general toVNC itself, so we're removing the HT_HVM prefix to the constant.
Support cdrom image and boot order for KVM
The cdrom image has the same meaning than in Xen HVM, and so doesboot_order, even though it has a slightly different syntax, and uses thevalue 'disk' too boot from disk and 'cdrom' to boot from cdrom.

HT_KVM doesn't technically require a port, but if it has one it can givevnc displays to instances.
KVM: add the HV_SERIAL_CONSOLE parameter
Up until now a KVM instance was forced to have a serial port.With this change this is no longer mandatory, by default we'll use one,but if the HV_SERIAL_CONSOLE parameter is set to False we'll do without.
KVM and Xen: add the HV_ROOT_PATH parameter
This parameter allows a different path to be passed to the instancekernel. The new parameter is mandatory, and by default has the value ofthe old hardcoded value for both kvm and xen.
Beta1 clusters will need to have this parameter added for their...
