Even as its Xen brain trust has departed, Citrix is moving ahead with an open source cloud IaaS strategy.
The deal is a big step forward for the virtualization company, which recently lost its two top Xen gurus, the founders of Xen.org, who left to launch a startup.
But there is a pending question: what will happen to Cloud.com's KVM support?
Citrix is committed to an OpenStack strategy and Cloud.com is now hypervisor agnostic. But today's press release makes no mention of KVM:
The Cloud.com product line will continue to support leading commercial hypervisors such as Citrix XenServer® and VMware vSphere, as well as open source hypervisors like Xen®. Citrix intends to add support for Microsoft products like Hyper-V and System Center to the Cloud.com product line, as well as support a full range of “platform-as-a-service” development environments, storage systems, servers and management software.
In March, Cloud.com announced a major upgrade of its platform that specifically points out support for KVM and Xen -- both open source hypervisors. Citrix has announced plans to support OpenStack.
Citrix has endorsed Xen for some time.
Here's Cloud.com's release on March, as compared to today's Citrix announcement:
CloudStack 2.2., which became available March 15, is a hybrid cloud solution that is hypervisor agnostic and ships with support for VMware vSphere 4, Citrix XenServer 5.6 and the open source Kernel-based Virtual Machine (KVM) running simultaneously in a single cloud, the company announced.
Update: Citrix confirmed that Cloud.com will continue to support KVM.
