Subject Re: Unable to create template
Date Sat, 13 Jun 2015 00:10:51 GMT
Sudhansu or any other XenServer expert, any ideas why my dom0 has this vdi
mounted?  Is it safe to unmount?  Is it because of some hierarchy of vhd
files?
My users are trying to create a templates from existing machines but are
blocked by this.

thanks,
Carlos
