Not in the wild yet, we hope
We have to await the details of Citirx' Oct. 1 announcement. Let's hope it's not in the wild yet. But once news of the exploit and the details of how it works are published, it will go into th wild, unless servers are protected against it.

Re: If hypervisor compromised, so potentially are 'private cloud' tenants
So we are talking about a hypervisor defect in the wild. That is notable given this has been a theoretical "what if" discussion until now among the virtualization community.

If hypervisor compromised, so potentially are 'private cloud' tenants
Amazon offers p-rivate cloud in a multi-tenant setting. The VPN and other connections are private, but on the same multi-tenant server sits a customer with an unsecured desktop. That's OK, provided there's no breach in the barriers imposed by the hypervisor, points out Scalr's Sebastian Stadil. If there is a breach, then Amazon's concept of private cloud as well as customers' "private" production systems are at risk. That's probably part of the reason Amazon is acting with such urgency in this case.
