@vahric-0 I don't believe that functionality exists yet for the newer REST API.

[vahric 0]

@Danp Okay, don't worry then without rest api , how could i automate this ? How XO doing it and how can i say to XO do it for out of REST ? @olivierlambert @julien-f

[Danp]

@vahric-0 See @julien-f response here -- https://xcp-ng.org/forum/post/75050

Once you know the JSON-RPC API syntax, then you should be able to automate it using xo-cli.

@Danp

I used the ?debug and from console i got the json call , thats okay.

Using @mbaron script , i get the methods and try to create network and looks like i could. Thank you very much

import json
import aiohttp
import asyncio

from jsonrpc_websocket import Server

async def routine():
    async with aiohttp.ClientSession() as client:
        server = Server('ws://XO ip address/api/', client)

        await server.ws_connect()

        # No signIn required
        methodsInfoResult = await server.system.getMethodsInfo()
        print('\n'.join([str(e) for e in methodsInfoResult.keys()]))

        # signIn required
        result = await server.session.signIn(username='username', password='password') # email attribute is working in place of username
        result = await server.network.create (pif='8369d867-a6f8-61f2-8132-3b485c3b3a63',pool='dd74abdd-7dd9-e95b-a241-dbd5b12b3ae1',name='deneme3',vlan=2346)
        print('[')
        print(', \n'.join([str(json.dumps(e, indent=4)) for e in result.values()]))
        print(']')

asyncio.get_event_loop().run_until_complete(routine())

result = await server.network.create (pif='8369d867-a6f8-61f2-8132-3b485c3b3a63',pool='dd74abdd-7dd9-e95b-a241-dbd5b12b3ae1',name='deneme3',vlan=2346)

I guess its will be perfect to move everything rest api and have well documentation.

One thing, i can not delete created test network because of HA, is it normal ?

IDK. What error did you receive?

[vahric 0]

@Danp I was getting error like below but right now i can delete it ? How it could happen ?

@vahric-0 You're saying that it worked in one instance but failed in a prior attempt? Did something change in the environment in between the attempts? Was the vlan in use by any VMs?

[vahric 0]

@Danp No, vlans was created only for test no any vm is attached
XO should not say to me this is used , you can not delete it ?
why its generating HA_IS_ENABLED message ?

[Danp]

@vahric-0 Sorry, but I'm not sure that I understand your setup. Perhaps it would help if you restated the issue making sure to address the following items --

• Is HA enabled on your pool?
• Are you able to delete the VLAN using XOA web interface?
• Are you able to delete the VLAN using XOA API?
• etc

[vahric 0]

@Danp

HA is enabled for the pool
After first creation network via api , i can not deleye it from gui
i did not tried delete vlan via api

I will try to reproduce

[vahric 0]

yeap , i did it again

[vahric 0]

[Danp]

@vahric-0 It is recommended to disable HA whenever you are performing maintenance (adjusting networking, applying updates, etc) on your pool.

[vahric 0]

@Danp if this is the rule , what i can say.
I will try one thing more because to create xostore step by step I shutdown servers and add disks after that i could delete the network

[Danp]

@vahric-0 I didn't understand what you were trying to say above. Are you unable to temporarily disable HA to perform maintenance?

[vahric 0]

@Danp No of course i can disable it , okay i will not struggle with it
After disable HA , i could delete it , thanks
