xo-cli help

kirovtome

Hi, i was messing around xo-cli and I'm kinda stuck with these ones:

xo-cli vm.create CPUs=1 deploys CPU limits: 1/2. How can i achieve something like CPU limits 2/4 ?
The same goes with memory. How can i configure min/max static and dynamic memory. I've tried with memory='json:[{"dynamic": [1073741824, 4294967296]}]' but no luck.
How can i update the SR size/name when deploying from template using custom config? (i'm using the CentOS 8 Cloudinit ready template from XO Hub)
How can i disable fast_clone checkbox?

Appreciate your help

badrAZ Do you have the answer to this one?
Use memoryMin & memoryMax
To alter disks inherited from the template, you must use existingDisks=json:'{"0": { "name_label": "New name", "$SR": "ddb10e9b-31a4-0354-8816-d3fd992f7fcb" } }'
Where 0 is the device of the existing disks (in fact the VBD between the VDI and the VM template).
clone=json:false

Hi,

For the first question, you can use cpusMax to set the CPUs limit. xo-cli vm.create cpus=2 cpusMax=4

Thanks a lot guys! julien-f could you provide me an example with memoryMin and memoryMax cuz when I try to run this command:

xo-cli vm.create template="118d4978-a9f9-ec99-52e3-df5e78b004a2" name_label="vmnew1" cloudConfig="centos8-cc" VIFs='json:[{"network":"40f00688-388d-997e-7f1c-12bbdf6134f8"}]' bootAfterCreate=true memoryMin=1073741824 memoryMax=1073741824

the output is:

✖ unknown error from the peer
JsonRpcError: unknown error from the peer
    at Peer._callee$ (/usr/local/lib/node_modules/xo-cli/node_modules/json-rpc-peer/dist/index.js:212:17) ..and so on

This works tho if i specify memoryMin or memoryMax only (not both). Also, do these memoryMin and memoryMax refer to the static or dynamic memory? I'm kinda newbie on this one.

badrAZ after the deployment, when i try to set the cpu, for example:

xo-cli vm.set id=<some_id> CPUs=4

i got this error:

✖ invalid parameters
  property @.CPUs: must be integer, but is string

If you know anything about this, please let me know.
Thanks!

It's not obvious but when you get unknown error from the peer you can go to the Settings/Logs of the web UI to have a detailed error.

Also, for non-string values, like CPUs, you need to prefix with json::

xo-cli vm.set id=<some_id> CPUs=json:4

julien-f Thanks a lot man! One more thing tho. It seems that i can't use existingDisks when i try to upgrade the VM disk size using vm.set. It says invalid parameter property @: should not contains property ["existingDisks"].

olivierlambert you can close this one tho. Many thanks!

julien-f

kirovtome Indeed, this param only applies to vm.create, not vm.set.

kirovtome

julien-f and what if i want to update the disk size. Is there any parameter that i can use with vm.set or is it another command?
