Problem with Proxmox 8.0 API qemu exec

[Rebirthz]

Hi,

I have install new Node with Proxmox 8.0.3.

Before this node I used API for config IP, DNS, firewall, etc..

But this Node cannot use API I setting same as other node



if it work It will return pid.




I'm try with shell command: qm guest exec 101 kvm fwoff
It actually work Turn off Windows firewall
I try another API command (get-users) it work.



In VM I have cloned it from another Node already install Virtio guest tool.

On PvE 8.0 Do I need to set anything up?

is there any error message when you try? what does the server return?

my guess is that you need to send the command parts as an array instead of a single string so

'command' => ['kvm', 'fwoff']

instead of

'command' => 'kvm fwoff'

Thanks for reply!!!

I try to change with your code
It show like this
stdClass Object ( [errors] => stdClass Object ( [command[1]] => property is not defined in schema and the schema does not allow additional properties [command] => property is missing and it is not optional [command[0]] => property is not defined in schema and the schema does not allow additional properties ) [data] => )



On my kvm.bat have to send command 'fwoff'


How can I send with parameter?

I use this in PvE 7.4
kvm fwon (to turn on firewall)
kvm fwoff (to turn off firewall)
kvm ipv4 192.168.0.0 (to setting VM Ip)

Thanks!

ok it seems that the request is somehow wrongly encoded? it tries to send command[0] and command[1] which is wrong, it has to send command as an array (which requires json encoding on the body. i don't know how or if you can configure that in your language/tools

what is the error message when you try your original request with 'command' => 'kvm fwoff' ?

this message show when use 'command' => 'kvm fwoff'

stdClass Object ( [data] => )


NOW I edit my code to array
with code "command" => ["kvm", 'fwoff']

it show this message
stdClass Object ( [errors] => stdClass Object ( [{"command":["kvm","fwoff"]}] => property is not defined in schema and the schema does not allow additional properties [command] => property is missing and it is not optional ) [data] => )

can you check what the exact/complete http request and response is?

Thanks for reply!

what do you mean ?
I'm sorry my bad in English

now i'm try this code

$create = array("command" => 'kvm',);
$send = Request::Request("/nodes/$firstNode/qemu/$vmid/agent/exec", $create, 'POST');
print_r($send);

Print

stdClass Object ( [data] => stdClass Object ( [pid] => 4012 ) )

It working normal but when I adding parameter like in PvE 7.4 It will not working

Example

$create = array("command" => 'kvm setIp 192.168.0.5 255.255.255.0 192.168.0.254');
$send = Request::Request("/nodes/$firstNode/qemu/$vmid/agent/exec", $create, 'POST');
print_r($send);

In PvE 7.4 it work normal.

but in php how it can have samekey i'm try

$create = array(
                "command" => 'kvm',
                "command" => 'fwon',
);

it cannot work

i mean i would like to see the raw http request and raw http response, not what you send/get in your php script, normally

now i'm try this code

$create = array("command" => 'kvm',);
$send = Request::Request("/nodes/$firstNode/qemu/$vmid/agent/exec", $create, 'POST');
print_r($send);

Print

stdClass Object ( [data] => stdClass Object ( [pid] => 4012 ) )

It working normal but when I adding parameter like in PvE 7.4 It will not working

Example

$create = array("command" => 'kvm setIp 192.168.0.5 255.255.255.0 192.168.0.254');
$send = Request::Request("/nodes/$firstNode/qemu/$vmid/agent/exec", $create, 'POST');
print_r($send);

In PvE 7.4 it work normal.

ok, so the api call changed so that it now takes an array instead of a string (and splitting somewhere)

i don't know which php client you use, but you either have to tell it to repeat the parameter (as you wrote) or to send the request parameter as json and use a proper array
