500 internal server

[shibumi]

Hello,
I have this code:

for node in proxmox.nodes.get():                     
    for vm in proxmox.nodes(node['node']).qemu.get():
        print(vm)

Why do I get a 500 internal server error for some servers?

ResourceException: 500 Internal Server Error:

[hbokh]

I get the same kind of error using POST (HTTP):

192.168.1.2 - root@pam [29/11/2018:20:49:32 +0100] "POST /api2/json/nodes/pve/qemu HTTP/1.1" 500 13

And in Ansible the last error looks like this:

"msg": "creation of qemu VM prov-test3 with vmid 101 failed with exception=500 Internal Server Error: b'{\"data\":null}'"

$ pveversion
pve-manager/5.2-12/ba196e4b (running kernel: 4.15.18-9-pve)

[hbokh]

Using the fix mentioned in #57 ([FIX] Add reasons to error codes) helped me one step further:

"msg": "creation of qemu VM prov-test3 with vmid 101 failed with exception=500 Internal Server Error: storage 'local-zfs' does not exists, Content:b'{\"data\":null}'"

[shibumi]

@hbokh does the storage really just exist? so your error message is valid and your fix is fixing the issue?

[hbokh]

The storage did not exist indeed (no ZFS). The additional error-message pointed me to where I had to fix things. So yes, the mentioned fix in #57 fixed my issue.
