Adapun cara untuk me-resize hardisk virtual sebuah vm di host xenserver 6.2 melalui command line adalah sebagai berikut (gunakan fitur "tab complete" untuk mempermudah dalam menuliskan perintah xe command yang tersedia).

Nah, cukup mudah bukan ?. Lihatlah sekarang ukuran hardisk virtual vm CentOS 6.4 Minimal sudah menjadi 170 GB (virtual-size ( RO): 171798691840).
Sampai disini tugas kita telah selesai. Langkah selanjutnya yang harus dilakukan adalah memperbesar ukuran partisi dari OS CentOS 6.4 Minimal itu sendiri. Untuk melakukan hal ini saya telah membahasnya pada tutorial yang telah lalu dan dapat anda baca disini.
Walaupun begitu saya tetap akan memperlihatkan proses memperbesar kapasitas hardisk didalam OS tersebut melalui baris-baris perintah dibawah ini.
[root@CentOS-6 ~]# fdisk /dev/xvdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0xa95dc7bc. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.
