Subject RE: [PROPOSAL] Support OVA files with multiple disks for templates and uploaded volumes in VMWare
Date Mon, 30 Sep 2013 15:26:54 GMT
Chip,

In Cloudstack, for Xen and KVM hypervisors since the files used for templates and volumes
are virtual disks (VHD, QCOW2) the current CS assumption of template and volumes containing
a single virtual disk seems fine. But since for VMware the files used for templates and volumes
are in OVA format which is an archive that can contain multiple VMDKs this improvement seems
appropriate only for VMware?
 
Thanks,
Likitha
