Hello,everyone
I have some questions about OpenStack Nova Compute(Essex).
According the Nova API Docs(http://api.openstack.org/),I sent stop command
to my vm
instance like follows:
curl -i -X POST -H "Content-Type: application/json" -H 'X-Auth-Token:<my
token>' \
-d '{"os-stop":null} ' \
http://localhost:8774/v1.1/<tenant id>/servers/<vm id>/action
Next,I checked the vm status:
nova list
This command returnd follows:
+--------------------------------------+----------+--------+-----------------+
| ID | Name | Status | Networks
|
+--------------------------------------+----------+--------+-----------------+
| e5d76e77-01eb-46a8-8086-f66835b39029 | vm_test2 | STOPED |
br100=10.16.2.5 |
+--------------------------------------+----------+--------+-----------------+
Well,I checked if the vm exsited:
virsh list --all
While,I found nothing.
Then, I sent start command to my vm instance like follows:
curl -i -X POST -H "Content-Type: application/json" -H 'X-Auth-Token:<my
token>' \
-d '{"os-start":null} ' \
http://localhost:8774/v1.1/<tenant id>/servers/<vm id>/action
check the vm:
nova list
+--------------------------------------+----------+--------+-----------------+
| ID | Name
| Status | Networks |
+--------------------------------------+----------+--------+-----------------+
| e5d76e77-01eb-46a8-8086-f66835b39029 | vm_test2 | ACTIVE |
br100=10.16.2.3 |
Here is my question:
1. Is the stop operation of vm instance means to delete the vm and keep
nothing except keep
this record in databases ?
2. Is the start operation of vm means to creat a new vm instance according
to the
recorde in databases ?
Waiting your reply . Thanks !
