* proxmox_kvm: remove redundant parameters
The functions start_vm() and stop_vm() receive four common parameters:
module, proxmox, vm and vmid.
The last too are redundant so keep only vm.
I also took the opportunity to remove extra API calls to proxmox.nodes()
by assigning its return value to a variable.
* proxmox_kvm: remove extra calls to status.current
The get_vm() function already returns an array of properties containing
the status so remove extra API calls to retrieve this information.
Example:
[{''netin'': 177232, ''name'': ''test-instance'', ''maxcpu'': 1, ''node'': ''prx-01'', ''disk'': 0, ''template'': 0, ''uptime'': 267, ''cpu'': 0.0410680030805531, ''diskread'': 165294744, ''maxdisk'': 10737418240, ''vmid'': 42, ''status'': ''running'', ''id'': ''qemu/42'', ''maxmem'': 536870912, ''diskwrite'': 18528256, ''netout'': 2918, ''type'': ''qemu'', ''mem'': 160284950}]
* proxmox_kvm: kill VZ_TYPE global variable
It reduces readability without providing much values nowadays.
* proxmox_kvm: simplify vmid generation
Forgotten suggestion from Felix Fontein in PR#811.
* proxmox_kvm: add changelog fragment for PR#934
Allows some factorization of redundant code in stop_vm(), start_vm(),
create_vm() and main().
This new function also waits one extra second after a successful task execution as the API can be a bit ahead of Proxmox.
Before:
TASK [ansible-role-proxmox-instance : Ensure test-instance is created]
changed: [localhost]
TASK [ansible-role-proxmox-instance : Ensure test-instance is updated]
fatal: [localhost]: FAILED! => changed=false
msg: VM test-instance does not exist in cluster.
After:
TASK [ansible-role-proxmox-instance : Ensure test-instance is created]
changed: [localhost]
TASK [ansible-role-proxmox-instance : Ensure test-instance is updated]
changed: [localhost]
With suggestions from Felix Fontein <felix@fontein.de>.
When the `vmid` parameter is not supplied and the module can only rely on
name look-up an early failure can happen if the targeted VM doesn't exist.
In this case a task execution with the parameter `state` set to `absent`
will actually fail instead of being considered ok.
This patch introduces a deferred error-checking for non-existent VMs
by assigning the value -1 to the `vmid` parameter, allowing the actual
verification to be performed in the right code paths.
Is also help to differentiate between a non-existent `vmid` or non-existent
VM `name`.
