Hello,
I would like know about your opinion about implement startup order on
xenserver/xcp
I did a little modification on "xapi-autostart-vms" file, idea is the next:
- other_config:auto_poweron now is false or true, for any reason seems not
boolean, then i can use "false" as value
- a two new fields on VM's other_config
- auto_poweron_after: contains a vm uuid, if this value has a vm uuid,
then is started when vm on auto_poweron_after field is in state "running"
- auto_poweron_after_tools, contains a vm uuid, if this value has a vm
uuid, then is started when vm on auto_poweron_after field has the field
"live" in true
An example:
xe vm-param-set uuid=df81d848-e246-8958-125e-ad53d72b32de
other-config:auto_poweron=after
xe vm-param-set uuid=df81d848-e246-8958-125e-ad53d72b32de
other-config:auto_poweron_after=b2e6f6e0-c981-372e-10c0-a51bbc7164ec (or xe
vm-param-set uuid=df81d848-e246-8958-125e-ad53d72b32de
other-config:auto_poweron_after_tools=b2e6f6e0-c981-372e-10c0-a51bbc7164ec)
