[Bug 1746796] [NEW] Error Compute API - Live-Migrate Server

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Good afternoon,

I'm experiencing difficulties with Computing API.

When I migrate VMs by command line everything works fine.

According to the command: openstack server migrate 7ca6ee39-bab1-422c-
a19f-1b73d2aeaf31 --live compute1 (OK)

But when I try to migrate through the API I get the following error:


{"computeFault": {"message": "Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.\n<type 'exceptions.KeyError'>", "code": 500}}


To request a migration through the API I am using the following Json:

Note: The variable $ TOKEN_AUTENTICACAO is all right, already testing.

        curl -s -H "Content-Type: application/json" -H "X-Auth-Token: $TOKEN_AUTENTICACAO" \
	-X POST http://controller:8774/v2/servers/7ca6ee39-bab1-422c-a19f-1b73d2aeaf31/action \
        -d '{
                "os-migrateLive": {
                        "host": "compute3",
                        "block_migration": "auto",
                        "force": false
                }
        }'

Can someone help me please? Sorry for English, I'm Brazilian.
