When retrieving VMs, you can configure the platform to skip the can request for the disk size of an ISO disk, to improve speed and reliability. This is especially useful if many VMs in your platform for ISO disks on retrieved VMs. This request depends on the full availability and speed of the datastores, and may affect the overall speed and reliability of VM retrieval, especially if many of the VMs in your environment use ISO disks.
By default
...
, from Abiquo 6.1.2 onwards, the platform does not request the size of ISO disks.
In previous versions, the platform requests the size of ISO disks.
To configure the platform to try to obtain the size of ALL disk files including ISO disk files, on the Remote Services servers, set the isoSizeSkip property to false.

Notes
This configuration The configuration to skip ISO disk size requests has the following limitations:
...
The platform updates datastore usage with a separate check, so the platform will correctly allocate datastore space.
Use cases
When you enable activate this configuration by setting isoSkipSize to true, the platform will not change the size of ISO disks already in VMs to 0.
When the configuration is enabledactivated:
If you retrieve VMs, the platform will skip the request to obtain the disk size and set disk size to
0for ISO disksIf you deploy a VM with a template that includes an ISO disk (e.g. ubuntu-install.iso), the ISO disk in the VM will have the size from the VM template
If you deploy a VM using cloud-init or add an ISO that is disk backed, the platform discovers the ISO disk, sets
size=0, and reports the datastore
After you disable deactivate this configuration, the platform will update the size of existing ISO disks in VMs to their correct size.
