The 'V-Index' study shows that across the countries an average of 39 percent of servers are virtualized, with a typical large business running 470 virtual machines and 113 hosts.
Over nine in 10 businesses use virtualization to some degree, the research found. But four in 10 see reliability concerns as a barrier to further virtualization, with a similar proportion waiting to refresh their hardware first.
The most widely used hypervisor is VMware, used by 84 percent of firms. Six in 10 also use Microsoft Hyper-V, fifty-five percent use Citrix Xen and 12 percent use alternatives.
The results were taken from a Vanson Bourne survey of 544 businesses, commissioned by virtualization management firm Veeam. The company plans to conduct the research quarterly and build the V-Index site into a community site where businesses can share their virtualization experiences.
"While the results show that virtualization has become a standard technology in most enterprises, it is clear that there is still room for increased penetration," said Ratmir Timashev, chief executive at Veeam.
