After the growpart package is installed for the image OS, the root partition of the BMS provisioned using the image can automatically expand disk capacity. SUSE OSs have growpart by default. However, the growpart version of SUSE 11 SP4 is too late, and you must install growpart of an earlier version. Ubuntu OSs have growpart by default and the growpart version meets requirements. During the XenServer installation, partitions cannot be selected. Therefore, automatic capacity expansion of the root partition is not supported.
