Deployed on Kebecloud to test on the same VM documented in OS-8683 here: OS-8683?focusedCommentId=132359
First I installed the experimental build on the head node.
[root@moe (kebecloud) ~]# sdcadm health vmapi
INSTANCE SERVICE HOSTNAME ALIAS HEALTHY
bdd3c089-444a-43de-9f0f-ad92dbece8de vmapi moe vmapi0 true
00000000-0000-0000-0000-0cc47a07f6ee global headnode global true
[root@moe (kebecloud) ~]# sdcadm services vmapi
sdcadm services: error (Usage): too many args: vmapi
[root@moe (kebecloud) ~]# sdcadm services | grep vmapi
vm 6c830538-2c09-46ca-a295-73eb5e1c1f1b vmapi 01686563-e2fa-463f-8548-dac9a47f9a60 1
[root@moe (kebecloud) ~]# Then let’s kick off a reprovision using VMAPI itself:
[root@moe (kebecloud) ~]# sdc-vmapi /vms/b66a6b8a-7e4f-4d98-9787-d39b0cfa5995\?action=reprovision -X POST -d '{ "image_uuid": "d89041d8-41b9-481d-918a-722be4598dd1" }'
