I do have a Virtuozzo VPS hosted in Melbourne, and the hosting company provides HSP complete control panel for me to login and view and change my account details. The column on the left also reports the resource usage of your VPS, showing you total traffic, amount of disk space, and the current “CPU usage”.

As you can see my VPS is currently using up 53% of CPU resource, out of 100% that is available. No wonder why my VPS feels so slow. However, when I actually jumped onto the VE and have a look, my processes weren’t using much CPU at all! vmstat shows my user and sys has always been under 5% combined (and under 2% most of the time). Type in upload shows that it is my 1 minute load average that is hovering around 0.5. HSP complete just conveniently interpreted to end user that VPS has used 50% of CPU resource, without trying to explain what load average is. That’s mad.

I was just reading Liam Eagle’s blogpost on SWSoft and Parallels. Apparently, Parallels, the developer of the Parallels Desktop — a hardware virtualization software on Windows, Linux and Mac — has actually been under a new management for three years. Who is the new owner? SWsoft, home of popular virtualization (Virtuozzo) and server automation (Plesk) software.

Kir Kolyshkin wrote on the OpenVZ blog, Why Virtuozzo is good for OpenVZ,

The first version of Virtuozzo was released about 6 years ago, so it is not something new. Virtuozzo costs money, and is used by big corporations for mission-critical applications. Virtuozzo customers expect it to be very stable, fast, bug-free, well documented, etc. And to sell the product successfully, those expectations must be met.
