Host CPU破百.....load那麼重?
是user用的?還是service用的?

要虛擬之前先給我實體機吧

Android Mini PC遞出

我老闆洽洽相反, 要我們使用實體機, 測試才使用VM, 他的理由是一籃雞蛋放在同一個籃子不好
同事都囧了...

Likely your company management has no intentions to buy enterprise virtualization license to enable the production environment with HA/vMotion/DRS/SRM features and just wants to use the FOC ESXi/Xen/Virtualbox/KVM hypervisor to have the testing instances in Virtualization environment.
It is fine since the proper license on the VM environment are quite expensive as initial costs. The proper hardware (SAN/vCenter server/HBA cards for Servers...) are also expensive. The MS-SQL cluster also has to enable it if in the VMware environment or physical servers environment since VMware is not able to ensure the vMotion can work properly in DB instances and apps instances without native clusterware (Windows Cluster/SQL cluster/IIS MLB/Web cluster....)
If the instances are Oracle related, all Oracle license based on the # of physical servers/cores, it does not matter run on the physical hardware or VM instances. Oracle will charge you full physical servers license.

也不用擔心什麼硬碟壞掉

錯了，我的ESXi就是硬碟老是掛掉

令人度爛的是，根本不知道他掛了，只知道某個vm超慢，然後拖累整台Host

『並不是』這個vm死掉而已。

或許改用企業硬碟吧，目前ESXi 5.0+5.1讓我用得非常不滿

嗯，想使用VMware ESXi 5.1的環境！
我會建議主機安裝SSD，安裝HostOS
另外GuestOS存放在外部的儲存空間，例如家用型含有2Bay的NAS，或是中小企業級，含有5Bay的NAS，可以開iSCSI or NFS方式存取！
效能不會慢喔！
且硬碟的狀態，可以從NAS的管理介面中看到！
維護資料與管理，這樣也比較方便喔！

老闆們常常會忘記一件事實，要虛擬之前先給我實體機吧！

中小企業的老闆們常常都不把錢花在刀口上
