Management muscle

We appreciated the flexibility that Virtuozzo offered us for managing VPSes.

We could create, monitor, update and manage our guest instances from a fat-client graphical console application that ran on both Windows and Linux workstations, from a Web-based administration portal, or from the command line of our Virtuozzo for Linux host system.

We were impressed with the range of management tasks we could undertake from all the Virtuozzo tools.

In addition to connecting directly to one of our guest instances via SSH (Secure Shell)—as weve been accustomed to doing with the VMware and Microsoft Virtual Server products weve recently tested—the Virtuozzo management consoles enabled us to start, stop and set default run levels for installed services. We could also browse and modify the file systems of the VPSes wed created.

Read here about how SWsoft virtualizes Egeneras blade servers. We could manipulate a variety of network configuration options on our VPSes, such as setting firewall rules, configuring network interfaces and setting traffic-shaping properties.

We also could add, remove and modify users and groups on our guest instances, as well as configure per-user disk quotas using Virtuozzos resource allocation features.

Virtuozzo exposes a somewhat dizzying array of resource allocation beancounters with which we could fine-tune the share of our host system so that each guest instance was assured access.

For example, the console presented us with 21 memory-related parameters to configure, either individually or, more simply, by choosing a sample configuration such as that for a VPS with 256MB of RAM.

We could also bump up the resource settings for a particular VPS en masse—such as by raising CPU, memory and storage limits by a factor of 1.5 across the board—or individually.

The products management tools also include consoles for managing FTP, mail and HTTP servers. During tests, we were able to get an FTP server on one of our Fedora Core 4 guests up and running rather simply by choosing the application template for ProFTPD for our VPS and checking the access, upload and connections options we desired.

We were impressed by the set of monitoring tools offered. We could choose which diagnostic characteristics to chart and then track them from the Virtuozzo consoles. We could also access detailed network traffic information.

We could join two or more hosts running Virtuozzo into a cluster, which enabled us to migrate VPSes from one host to another without disrupting their uptime, as well as back up our VPSes between the hosts in the cluster.
