How can we create vm using curl?

[hcrai]

I am able to create lxc following this docs https://pve.proxmox.com/wiki/Proxmox_VE_API#Creates_a_LXC_Container however I was not able to create vm trying similar. Is there anyway to create VM?

Is there anyway to create VM?

Yes, it's the same. You only need to create the disk first and create the VM with the previously created VM.

 

[Folke]

There is a full api viewer at <your instance>/pve-docs/api-viewer/index.html.
Under nodes > {node} > qemu you can find the endpoint and options for creating a new vm

Yes, it's the same. You only need to create the disk first and create the VM with the previously created VM.

you can also do it in one go - either importing some template disk or creating a new blank one, e.g. for scsi disks:

scsi[n]

string

[file=]<volume> [,aio=<native|threads|io_uring>] [,backup=<1|0>] [,bps=<bps>] [,bps_max_length=<seconds>] [,bps_rd=<bps>] [,bps_rd_max_length=<seconds>] [,bps_wr=<bps>] [,bps_wr_max_length=<seconds>] [,cache=<enum>] [,cyls=<integer>] [,detect_zeroes=<1|0>] [,discard=<ignore|on>] [,format=<enum>] [,heads=<integer>] [,import-from=<source volume>] [,iops=<iops>] [,iops_max=<iops>] [,iops_max_length=<seconds>] [,iops_rd=<iops>] [,iops_rd_max=<iops>] [,iops_rd_max_length=<seconds>] [,iops_wr=<iops>] [,iops_wr_max=<iops>] [,iops_wr_max_length=<seconds>] [,iothread=<1|0>] [,mbps=<mbps>] [,mbps_max=<mbps>] [,mbps_rd=<mbps>] [,mbps_rd_max=<mbps>] [,mbps_wr=<mbps>] [,mbps_wr_max=<mbps>] [,media=<cdrom|disk>] [,queues=<integer>] [,replicate=<1|0>] [,rerror=<ignore|report|stop>] [,ro=<1|0>] [,scsiblock=<1|0>] [,secs=<integer>] [,serial=<serial>] [,shared=<1|0>] [,size=<DiskSize>] [,snapshot=<1|0>] [,ssd=<1|0>] [,trans=<none|lba|auto>] [,werror=<enum>] [,wwn=<wwn>]

Use volume as SCSI hard disk or CD-ROM (n is 0 to 30). Use the special syntax STORAGE_ID:SIZE_IN_GiB to allocate a new volume. Use STORAGE_ID:0 and the 'import-from' parameter to import from an existing volume.

I had used this
```
curl --silent --insecure --cookie "$(<cookie)" --header "$(<csrftoken)" -X POST \
-d '{
"name": "my-vm",
"vmid": 121,
"ostype": "l26",
"ide2": "local:iso/CentOS-Stream-8-x86_64-latest-boot.iso,media=cdrom",
"virtio0": "local:local:101/vm-101-disk-1,cache=writeback",
"sockets": 1,
"cores": 2,
"memory": 2048,
"net0": "virtio,bridge=vmbr0"
}' \
https://<hostname>:8006/api2/json/nodes/proxmox2/qemu
```
I am getting this error
"vmid": "property is missing and it is not optional",

 

[fabian]

the VMID is a path parameter that goes into the URL in this case, not into the body.

note that you can just copy a valid curl command line from your browser's dev console for any request the UI does

edit: removed wrong advice - @Folke Gleumes below has the correct hint!

 

[Folke]

The request is missing the mimetype.
Add -H "Content-Type: application/json" to your curl options

you can also do it in one go - either importing some template disk or creating a new blank one, e.g. for scsi disks:

Oh sorry, I was mistaken, the thing you needed before was a valid and empty vmid.
