Joshua Boniface 79eb994a5e Ensure equality of none and None for selector 2022-11-07 11:59:53 -05:00

Joshua Boniface d8d3feee22 Add selector help and adjust flag name
1. Add documentation on the node selector flags. In the API, reference
the daemon configuration manual which now includes details in this
section; in the CLI, provide the help in "pvc vm define" in detail and
then reference that command's help in the other commands that use this
field.

2. Ensure the naming is consistent in the CLI, using the flag name
"--node-selector" everywhere (was "--selector" for "pvc vm" commands and
"--node-selector" for "pvc provisioner" commands).

Joshua Boniface 9ea9ac3b8a Revamp tag handling and display
Add an additional protected class, limit manipulation to one at a time,
and ensure future flexibility. Also makes display consistent with other
VM elements.

Joshua Boniface c0a3467b70 Simplify VM metadata reads
Directly call the new common getDomainMetadata function to avoid
excessive Zookeeper calls for this information.

Joshua Boniface 9a199992a1 Add functions for manipulating VM tags
Adds tags to schema (v3), to VM definition, adds function to modify
tags, adds function to get tags, and adds tags to VM data output.

Tags will enable more granular classification of VMs based either on
administrator configuration or from automated system events.

Joshua Boniface d1d355a96b Avoid errors if stats data is None 2021-07-09 13:13:54 -04:00
Joshua Boniface e44f3d623e Remove unnecessary try/except blocks from VM reads
The zkhandler read() function takes care of ensuring there is a None
value returned if these fail, so these aren't required. Makes the code a
fair bit more readable here.

Joshua Boniface baf4c3fbc7 Add performance profiler function
Usable anywhere that the global daemon "config" parameter can be passed
in (e.g. pvcapid/helper.py, pvcnoded/Daemon.py, etc.). Stores results in
a subdirectory of the PVC logdir called "profiler" if this directory can
be created, or prints results.

The debug config parameter ensures that the profiler can be added to
functions and not run unless the server is explicitly in debug mode.
Might not be useful as I don't initially plan to add this to every
function (only when investigating performance problems), but this
flexibility allows that to change later.

Joshua Boniface a48bf2d71e More gracefully handle none selectors
Allow selection of "none" as the node selector, and handle this by
always using the cluster default instead of writing it in.

information about the live VNC listen address and port for VNC-enabled
VMs.

Joshua Boniface ec0b8acf90 Support per-VM migration type selectors
Allow a VM to specify its migration type as a default choice. The valid
options are "default" (i.e. behave as now), "live" which forces a live
migration only, and "shutdown" which forces a shutdown migration only.
The new option is treated as a VM meta option and is set to default if
not found.

Joshua Boniface f749633f7c Use provisioned memory for mem migration selector
Use the new "provisioned" memory field, instead of the "allocated"
memory field, to determine the optimal node when using the "mem"
migration selector. This will take into account non-running VMs in the
calculation as well as running VMs.

Joshua Boniface e419855911 Support converting types during upload
Allow the user to specify other, non-raw files and upload them,
performing a conversion with qemu-img convert and a temporary block
device as a shim (since qemu-img can't use FIFOs).

Also ensures that the target volume exists before proceeding.
