How To Increase Disk Space on a Xen Server VM
I know this is a simple task, but to just give a few easy pointers for those who can't see it.
With XenCenter 5.6 you can select the VDI from the storage tab of the virtual machine click Properties, select Size and Location, then increase the size of the disk without using the command line.
Using Disk Management:
Right click My Computer select Manage.
Select Disk Management, right click on the disk you want to extend, and select Extend:
This starts the Extend Volume Wizard. Follow the prompts to complete the process.
