Proxmox VE 1.2 is running Kernel-based Virtual Machine (KVM-85) and OpenVZ on Debian 5.0. It is a 64-bit system and works with virtualization capable CPU. It equipped with a web-based control panel and allows you to create, delete and modify the virtual guests from it. You can also backup the virtual guests with cron job. It is a very good and easy way to implement the virtualization environment. However, Proxmox VE does not support fakeRAID and software RAID. A hardware RAID card is required.
It will halt at 99% during installation and you should be patient and the process will be completed within minutes.
You can access each guest via VNC which is running under Java. It is quite responsive under my Gigabit home network. You cannot use keyboard and mouse unless you pointed your mouse cursor on the guest window. However, the mouse wheel does not work in this release. According to the reply from forum that this feature may be supported in the future. In addition, since the VNC viewer is running under Java, the guest does not support any Java applet from execution, such as http://www.ppshk.com for example.
It provides some appliances for OpenVZ, such as mail gateway, Debian, CentOS, Ubuntu, Drual, WordPress, SugarCMS and etc. You can implement the appliances with a few clicks. You can create your appliance template very easily (you can refer to her wiki website). Furthermore, You can install other Linux distributions or Windows systems via iso or CD-ROM for the KVM but not the OpenVZ.
Since my motherboard equipped 2 PCI-Express x1, I bought a 3Ware 9650SE-2LP which supports 2 SATA II ports for RAID 0, 1 and JBOD. It is quite expensive ($1,800-HK) and without battery backup. The configuration of RAID 1 is very easy via its BIOS. You can also configure the RAID card by browser through its Disk Manager software but it is not yet tested by me.
In conclusion, Proxmox VE is ideal for server virtualization. It is very easy to create, delete and modify any virtual guest server with a few clicks. Let’s go Green Computing!
