[pve-devel] [PATCH qemu-server v2 16/32] vm start: move config_to_command() call further down

[Fiona Ebner]

For command line generation of '-blockdev', it will be necessary to
activate the VM's volumes before calling config_to_command() and thus
also deactivate in an error scenario. Avoid the need to put more code
than necessary into the resulting eval.

Changes in v2:
* For templates, keep using minimized config for timeout calculation.
