Review request for cloudstack and Abhinandan Prateek.


Did you file a bug with XS that 13 is a limit since the users of CS might get confused why
this being the limit instead of 14?

>> Following up with XenServer team on this.


Support for up to 16 VDIs per VM on XS 6.0 and above (16 VDIs => root + cd + 14 data volumes).
Currently in CS number of data disk that can be attached to VM is hard-coded to 6. Made this
setting configurable by moving it to hypervisor capabilities. Although XS 6.0 and above supports
upto 16 VDIs but while testing on XS 6.0.2 found that only 13 data volumes can be attached
to a VM. So for XS 6.0 and 6.0.2 max_data_volumes_limit is set to 13 currently.
