Instalasi VMware Tools pada VM Berbasis SUSE Linux Enterprise Server Menggunakan VMware OSP

Pada tulisan sebelumnya saya sudah menulis mengenai tata cara instalasi VMware Tools pada VM berbasis SUSE Linux Enterprise Server menggunakan cara standard. Pada artikel ini saya akan membahas mengenai cara instalasi VMware Tools dengan langkah yang lebih singkat dan mudah, yaitu menggunakan Operating System Specific Packages for VMware Tools (OSPs).

Apa itu Operating System Specific Packages for VMware Tools (OSPs)?

OSPs for VMware Tools is a packaging and distribution mechanism for VMware Tools. These OSPs use the native package formats and standards of the supported guest operating systems. OSPs are an alternative to the existing mechanism used to install VMware Tools through the VMware

vSphere™ Client. With OSPs you can use the native update mechanisms of your operating system to download, install, and manage VMware Tools. With OSPs you can manage VMware Tools from the virtual machine as you would other standard software.

Berikut adalah cara instalasi VMware Tools berbasis OSP pada VM berbasis SUSE Linux Enterprise Server 11. Metode yang sama bisa digunakan pada VM berbasis Red Hat atau Debian family dengan menyesuaikan perintah instalasi package dan tipe package yang dipergunakan.

PERSIAPAN

1. Check versi VMware vSphere Host yang digunakan. Host yang saya pergunakan adalah VMware vSphere versi 5.1 update 1, bisa diketahui dari informasi VMware vSphere yang dipergunakan atau bisa juga dicheck pada data summary host vSphere
2. Check versi SUSE Linux yang dipergunakan dan tipe kernel yang sedang dipakai dengan perintah : cat /etc/SuSE-release dan uname -a. Contoh hasilnya seperti berikut ini :
   [code lang=”bash”]
   mail:~ # cat /etc/SuSE-release
   SUSE Linux Enterprise Server 11 (x86_64)
   VERSION = 11
   PATCHLEVEL = 2
   mail:~ # uname -a
   Linux mail 3.0.58-0.6.6-default #1 SMP Tue Feb 19 11:07:00 UTC 2013 (1576ecd) x86_64 x86_64 x86_64 GNU/Linux
   [/code]
   Hasil diatas menunjukkan bahwa VM menggunakan SLES 11 SP2 64 bit dengan tipe kernel : default
3. Jalankan proses instalasi dengan perintah :
   [code lang=”bash”]
   zypper ar http://packages.vmware.com/tools/esx/5.1u1/sles11.2/x86_64/ vmware-tools
   zypper ref
   zypper install vmware-tools-collection vmware-tools-esx-kmods-default vmware-tools-esx
   [/code]
   Jangan lupa ganti 5.1u1 dengan versi vSphere yang dipergunakan, sles11.2 dengan versi SUSE yang digunakan dan default dengan tipe kernel yang dipergunakan. Untuk repository versi vsphere dan versi lainnya bisa merujuk pada link http://packages.vmware.com/tools/esx
4. Tunggu prosesnya selesai dilakukan.
   [code lang=”bash”]
   mail:~ # cat /etc/SuSE-release

   PATCHLEVEL = 2
