			<content:encoded><![CDATA[<p><a href="http://lumanau.web.id/wp-content/uploads/2011/06/xen_logo.gif"><img class="alignleft size-full wp-image-1519" title="Xen" src="http://lumanau.web.id/wp-content/uploads/2011/06/xen_logo.gif" alt="Xen" width="149" height="67" /></a>Di salah satu perusahaan tempat saya bekerja, kebetulan sekarang ini sering overload. Dan gak punya server dengan spesifikasi yang sesuai, cuma punya beberapa server dengan specs yg &#8220;Maknyuz&#8221; dan pastinya jadi <em><a href="http://en.wikipedia.org/wiki/Overkill" target="_blank">overkill</a></em></p>
<p>Karena waktu yang mepet, daripada tidak ada tambahan <em>pasukan, </em>jadi digunain aja server itu. Cara agar biar tidak jadi <em>overkill </em>yaitu dengan membuat <span style="text-decoration: underline;"><em><a href="http://en.wikipedia.org/wiki/Virtualization" target="_blank">Virtualization</a></em></span> terhadap server tersebut. Apa sih Virtualization itu? Bahasa mudahnya, artinya ada 1 server besar, tapi kita pecah menjadi beberapa server kecil. Tapi fisiknya sendiri tetap hanya 1 server.</p>
<p>Yuk sekarang kita masuk ke bagian teknisnya <img src='http://lumanau.web.id/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p><span id="more-1517"></span>Di dalam installasi kali ini, kita akan menggunakan <a href="http://www.xen.org" target="_blank">Xen</a>. Paket2 dari Xen sendiri sudah ada di dalam repositori Debian, jadi akan jauh lebih mudah dan cepat installasi kita kali ini <img src='http://lumanau.web.id/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<p>Pertama, kita install paket2 yang dibutuhkan</p>
<blockquote><p>apt-get install -y xen-hypervisor xen-linux-system xen-utils xenstore-utils xenwatch xen-tools</p></blockquote>
<p>Selanjutnya kita buka file <strong>/etc/modules</strong>. By default, di dalam file <strong>/etc/modules</strong> ada line hanya berisi kata <em>loop</em>. Line tersebut kita edit menjadi</p>
<blockquote><p>loop max_loop=64</p></blockquote>
<p>Berikutnya, kita harus edit file <strong>/etc/xen/xend-config.sxp</strong>. Di dalam file ini, ada 2 line yang perlu kita edit dan periksa kembali. Berikut adalah line yang perlu ditambahkan</p>
<blockquote><p>(network-script &#8216;network-bridge antispoof=yes&#8217;)</p></blockquote>
<p>Line di bawah ini, seharusnya by default sudah aktif, tapi tidak ada salahnya diperiksa kembali <img src='http://lumanau.web.id/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<blockquote><p>(vif-script vif-bridge)</p></blockquote>
<p>Config? Beres.. Sekarang coba restart servernya</p>
<blockquote><p>reboot</p></blockquote>
<p>Setelah reboot selesai, kita periksa kembali, apakah server sudah booting dengan menggunakan kernel xen atau belum</p>
<blockquote><p>root@localhost:~# uname -r</p>
<p>2.6.32-5-<strong>xen</strong>-amd64</p></blockquote>
<p>OK berarti server sudah menggunakan kernel Xen. Nah untuk menggunakan fitur hypervisor pada saat sistem pertama kali booting, kita harus merubah dulu boot ordernya</p>
<blockquote><p>mv /etc/grub.d/10_linux /etc/grub.d/50_linux</p>
<p>update-grub2</p></blockquote>
<p>Apa yang terjadi abis kita upgrade grub nya? Akan muncul informasi seperti ini</p>
<blockquote><p>Generating grub.cfg &#8230;Found linux image: /boot/vmlinuz-2.6.32-5-xen-amd64</p>
<p>Found initrd image: /boot/initrd.img-2.6.32-5-xen-amd64</p>
<p>Found linux image: /boot/vmlinuz-2.6.32-5-xen-amd64</p>
<p>Found initrd image: /boot/initrd.img-2.6.32-5-xen-amd64</p>
<p>Found linux image: /boot/vmlinuz-2.6.32-5-amd64</p>
<p>Found initrd image: /boot/initrd.img-2.6.32-5-amd64</p>
<p>done</p></blockquote>
<p>Value / kernel nya kemungkinan berbeda ya, karena itu yang muncul pada saat saya coba. Sekarang kita reboot lagi servernya, agar boot ordernya berjalan sesuai dengan yang kita inginkan.</p>
<p>Setelah reboot selesai, ketik <strong>dm dmesg</strong>, akan muncul seperti</p>
<blockquote><p>root@localhost:~# xm dmesg</p>
