There is an error detected with Pandora FMS’ VMware® image on VMware® 4.1 systems. The error detected is the following:
Module DevicePowerOn power on failed. Unable to create virtual SCSI device for scsi0:0, '/vmfs/volumes/5113db7a-9a00a928-45ad-001a646a1c38/Pandora 4.0.3/Pandora_4.0.3_OpenSource_Appliance.i686-0.0.22.vmdk' Failed to open disk scsi0:0: Unsupported or invalid disk type 7. Make sure that the disk has been imported.
To solve this error just change the virtual disk format. To do this clone the disk using the following command
vmkfstools -d thin -i "Pandora_4.0.3_OpenSource_Appliance.i686-0.0.22-s001.vmdk" "Pandora_4.0.3_new.vmdk"
Now you can assign this new one called Pandora_4.0.3_new.vmdk to the virtual machine and it should start without problems.
