2 a.m.
This is another rework of how this flow should work, after more thought and
discussion with Aline.
This new flow removes the 'auto-topology' element from the API and makes it so
that
users can enter varying information without being dinged for not doing exactly the
right thing (e.g. vcpus != sockets * cores * threads).
It also works in a way that doesn't require the UI to have access to the kimchi Model
objects (as I misremembered for the previous patches).
1. UI calls GET host/cpuinfo
curl -k -u user -H 'Content-Type: application/json' \
-H 'Accept: application/json' https://localhost:8001/host/cpuinfo
{
"cores":2,
"threading_enabled":true,
"sockets":1,
"threads_per_core":2
}
2. UI displays appropriate title and checkboxes
- If host arch is Power:
- Display a menu labled SMT, with up to four check-boxes.
The check-boxes will be labeled SMT1, SMT2, SMT4, and SMT8.
The max SMT value displayed will be dependant upon
threads_per_core from above. The default checkbox should be the
greatest SMT value (e.g. SMT8).
- Display the same box for CPUs as before. This value may change
when the backend template creation is done, so if there's any way
to pop up "Here are the values of your new template," kind of
message,
that would be nice. Otherwise, we'll just make it clear in the doc
that the vCPUs value entered is not guaranteed.
- Else:
- Display a menu labeled Hyper-Threading, with only a checkbox labeled
HT.
Note: The same comments for vCPUS as above apply here. The number
maybe need to change based on the CPU capabilities.
3. UI calls POST template with threads value set to '0' (x86) or SMTX (Power)
Note that vcpus is still optional, so no change in how that's handled needs
to be done.
$ curl -k -u user -X POST -H 'Content-Type: application/json' -H 'Accept:
application/json' https://localhost:8001/templates -d'{"name":
"test_auto_topo", "cdrom":
"/home/iso-pool/Fedora-Live-Desktop-x86_64-20-1.iso", "cpu_info":
{"topology": {"threads":0}}}'
{
"cpus":1,
"cpu_info":{
"topology":{
"cores":1,
"threads":1,
"sockets":1
}
},
"graphics":{
"type":"vnc",
"listen":"127.0.0.1"
},
"cdrom":"/home/iso-pool/Fedora-Live-Desktop-x86_64-20-1.iso",
"networks":[
"default"
],
"icon":"images/icon-fedora.png",
"os_distro":"fedora",
"name":"test_auto_topo",
"disks":[
{
"index":0,
"size":10
}
],
"invalid":{},
"os_version":"20",
"storagepool":"/storagepools/default",
"memory":1024,

}
