How to expand a VM disk using xo-cli?
-
I'm trying to expand a VM disk using xo-cli or some automated method with a script. Anyone done this before and have an example?
-
I figured out how to expand a VDI disk if I can get the id of the disk. But how do I get a list of disks attached to a VM if I have the name label of a vm? This is what I would run to get object details of the vm but I was hoping it would show a list of VDI ids attached to this VM but it doesn't.
xo-cli list-objects name_label=vmtest1

@eeldivad I think i can "help" somewhat. the "new" and probably more supported in the future way as I see it is doing stuff through xen orchestra Rest api (not everything is possible there yet however)
http://[yourXO]/rest/v0/vms
this endpoint is pretty "fire" as the kids say
as per the README of the rest-api here
you can add fields to the result, so adding "name_label" like so:
http://[yourXO]/rest/v0/vms?fields=name_label
http://[yourXO]/rest/v0/vms?fields=name_label&filter=[namelabelSearch]
we can then search this output for the VM UUID we want (if you didn't just filter the api query)
in my example i want "9a5730fa-77bc-1730-4583-c383cbc5c1f1"I then call:
http://[yourXO]/rest/v0/vms/9a5730fa-77bc-1730-4583-c383cbc5c1f1/vdis
which again is a list of endpoints like this:
/rest/v0/vdis/cd59c164-b382-4a5c-8449-e668d31696da
the last part after "vdis" is the disk UUID, you could then call that endpoint to get the VDI size, usage etc.
Hope this was somewhat helpful
I did not see a easy way to get this from xo-cli but I figured you can probably get the UUID's from REST and then the "rest" on xo-cli

@Gurve I was trying it your way and then I noticed something in the doc where we can use xo-cli to call any REST method. So from your example we can do the following in xo-cli
get all VMs
xo-cli rest get vmsget single vm with id. this includes the VDI disks IDs I needed
xo-cli rest get vms/d55b0683-2fb9-7b06-6fa5-be6f2065e4b5get vdis for a vm by vm id
xo-cli rest get vms/d55b0683-2fb9-7b06-6fa5-be6f2065e4b5/vdisget VDI details with vdi ID
xo-cli rest get vdis/50436f36-5d5b-4048-9834-2cad0b869f66Thank you so much!! you solved my problem

@Gurve Even though I figured out how to do it all in xo-cli now, I haven't figured out how to build the filter search in the querystring using the API method you mentioned above. Could you give me a couple examples for my curiosity as I may need it in the future.
&filter=[namelabelSearch] -
@eeldivad Cool that you can call the rest api's through there!
I mess about in the web browser, seems to use the cookie that XO web ui uses (ie. logging in to web ui also makes you able to call api in web browser)
my bad for not including a example, namelabel was supposed to hint at displayname of VM
http://[yourXO]/rest/v0/vms?fields=name_label&filter=app
this returns all vm's with "app" in their name_label (displayname)
according to this documentation
filter should be compatible with the search bar in XO, so you can make your query there by selecting pools etc. in GUI and it just seems to work (tested just now
)http://[yourXO]/rest/v0/vms?fields=name_label&filter=power_state:running+tags:/^ansiblegrp_linuxbaseline$/
I created the above query in GUI and just tested "+" between and it seems to work. This returns running vms that are also tagged with "ansiblegrp_linuxbaseline" which i use for my ansible inventory (xen orchestra has a pretty nifty inventory plugin)

@Gurve Oh wow that's neat! It works! very cool we can use the same query search from the GUI.
Thank you.
