[ovirt-users] Ovirt api function

[Shanil S]

Hi,

VM rebuild means...Rebuild the VM with the same existing
configuration...just erase the Vdisk and install again (like Fresh
install).
We want to rebuild the VM with the same existing OS template...also it will
be good if user can select other OS template also for the rebuild
purpose...
With CD_ISO it require the manual installation...we don't want the manual
installation...we looking for a way to rebuild the VM with OS templates....
Is there any API method to achieve this ??

Regarding the statitics report, is there any API method to fetch the
monthly and weekly usages report ?, we are planning to create a usage chart
by using these values.

Shanil
