Is it possible to pause a VM from API?

[IvanGomezGon]

Hey! So I can see from the API viewer you can reboot, reset, resume, shutdown, start, stop and suspend, but there seems to be no option to pause a VM.
Am I missing something obvious? Could I instead suspend to get a similar effect?

Thanks!

Pause and Suspend are the same thing. You can confirm that by :
a) tail -f /var/log/pveproxy/access.log
b) execute Pause via gui
c) notice the API called:
::ffff:172.16.9.3 - root@pam [06/06/2023:14:05:03 -0400] "POST /api2/extjs/nodes/pve7demo1/qemu/301/status/suspend HTTP/1.1" 200 86

I see, thanks! Only problem I encounter is when I retrieve the status, I can't differentiate from paused and running, in both cases shows as running. Any ideas how to get around it?

Indeed, with status/current I can get the qmpstatus with no problem, the problem arises with nodes/{node}/qemu. As said in the doc https://pve.proxmox.com/pve-docs/api-viewer/index.html#/nodes/{node}/qemu it should also contain qmpstatus, but for each VM of the cluster, I only get this params, where qmqstatus is nowhere to be found:

cpu:0.634245694812055
cpus: 1
disk: 0
diskread: 0
diskwrite: 0
maxdisk: 34359738368
maxmem: 2147483648
mem: 43727506
name: 'Copy-of-VM-proxmoxtest'
netin: 94
netout: 0
pid: 24276
status: 'running'
uptime: 2543
vmid: 101

the document describes two parameters that you can specify, one of them is optional - give it a try

shoot, that's just what I needed, but when I define full=true to get the full status, it still outputs the same as before. Anyways, I will just loop for each node and get currentStatus or I will just check if CPU Usage is minimum, thanks for the help!
