Possible to add some code in volumeObject->
processEvent(ObjectInDataStoreStateMachine.Event event, Answer answer)
if (this.dataStore.getRole() == DataStoreRole.Primary) {
if (answer instanceof CopyCmdAnswer) {
else if (answer instanceof CreateObjectAnswer) {
if (newvol.getImageFormat() != null) {
vol.setImageFormat(newvol.getImageFormat())
}
In the KVM resource code, need to return an image format in
kvmstorageProcessor:
Answer createVolume(CreateObjectCommand cmd)
And also need to move the following code:
VolumeVO volVO = _volsDao.findById(vol.getId());
volVO.setFormat(getSupportedImageFormatForCluster(rootDiskHyperType));
_volsDao.update(volVO.getId(), volVO);
