[pve-devel] [PATCH-SERIES v2 pve-manager/qemu-server] fix#4689 autofind node with proxyto_callback

[Alexandre Derumier]

Hi,

Currently, to manage qemu && lxc vms, we always need to specify nodename in uri.

This is a problem with automation tools like terraform, where is node is registered
in the state of terraform.
(That mean, than if we move the vm on another node, terraform don't known it, and try to create the vm
again or can't delete the vm,...)
https://github.com/Telmate/terraform-provider-proxmox/issues/168

This can also be a potential problem with race, if we need to query /cluster/ressources to find the node, then another
query on the vm.

I have some discussion with fabian about it:
https://bugzilla.proxmox.com/show_bug.cgi?id=4689


This patch series, find the nodename with proxyto_callback.

a new api endpoint /guests/  is defined:

/guests/(qemu|lxc)/vmid


This patch series currently implement callback for api2::qemu

todo (if this patch serie is ok for you):
api2::qemu::agent   (/guest/qemu/vmid/agent)
api2::lxc   (/guest/lxc/vmid)
api2::lxc::config   (/guest/lxc/vmid/config)
api2::lxc::status   (/guest/lxc/vmid/status)
api2::lxc::snapshot   (/guest/lxc/vmid/snapshot)
api2::firewall:vm (/guest/(qemu|lxc)/vmid/firewall )


changelog v2:

- fix pvesh param sending to proxyto_callback


pve-manager:

Alexandre Derumier (2):
  api2: add /guests path
  pvesh: send params to check_proxyto like httpserver

[pve-devel] [PATCH pve-manager 2/2] pvesh: send params to check_proxyto like httpserver

[Alexandre Derumier]

Currently only url_params are send to check_proxyto, the behaviour
is different than httpserver.

for example, so we can't retreive "pvesh create ... --node" param
in proxyto_callback
