...
The server has two main modules: v2v-diskmanager and mechadora.
v2v-diskmanager performs format conversions
mechadora performs dumps to volumes and reads from volumes and disks.
The v2v-diskmanager uses two utilities to convert templates: qemu and vBoxManageSVC.

Possible issues with the BPM and V2V Server
...
The working folder for V2V Conversions is /opt/abiquo/v2v-conversions.
The completed conversions are stored in the catalogue (on the NFS repository) in the formats folder.
...
Check a V2V conversion that is in progress
...
If a conversion is in progress, the v2v-diskmanager and mechadora processes will be running. You can check them with the following commands.
Check the
v2v-diskmanagerprocess is running - see Service Management#v2v-diskmanager.:ps aux | grep v2v
Check the
mechadoraprocess is running withps aux | grep mechadora
Using top
If a conversion is in progress and you are running "top", you will see the following:
...
The V2V properties are shown in the following sample file (by default this is: /opt/abiquo/config/examples/abiquo.properties.v2v)
Sample abiquo.properties on V2V Server
| Code Block |
|---|
[remote-services] abiquo.rabbitmq.host = <RabbitMQ-Server-IP> abiquo.rabbitmq.port = 5672 abiquo.rabbitmq.username = guest abiquo.rabbitmq.password = guest abiquo.datacenter.id = Abiquo |
You should set
abiquo.rabbitmq.hostto the IP address of the RabbitMQ Server. The default is the Abiquo Server.The
abiquo.datacenter.idshould be a unique value for each datacenter and the same value as for the Remote Services server.The other values should be set to appropriate values for your installation of RabbitMQ. You do not need to change these values for a default installation.
See Abiquo configuration properties
...
Yes, the NFS Repository is required on the V2V Conversion Services machine. Check that the NFS repository is mounted in the correct location. You can use the "df" command for example. The default location is /opt/vm_repository
...
Check the appropriate ports are open for the V2V Server
