Citrix XenServer SOA Performance Engineering Team, wrote OSA a series of articles on how they reached a density of 500 VMs per host on XenServer 6.2. This is a must read for anyone interested in understanding the performance of the hypervisor and architecture and includes information on how our engineering team investigate the performance and throughput and internal secrets. Warning contains a depth technical overview!
Jonathan Davies, AO first blog on the subject gives an overview of events in XenServer channels and improvements in our engineering team has done. His colleague Felipe Franciosi continues the story covering the CPU usage of the QEMU process and USB emulation; Jonathan then resumes the tale in a new blog detailing our position today covering XenServer architectural features such as dom0, blktap2, xenstored, requests for aio, comforted and low dom0 memory.
Many of our partners such as Dell and HP are now making very large servers and be able to support that number VM provides customers should not experience all the limitations of the hypervisor. It, AOS also great for other Citrix products that are deployed on the XenServer platform such as NetScaler SDX, XenDesktop, and CloudPlatform VDI-in-a-box.
There, AOS much marketing information on why the VM density issues available, but these new blogs are intended for developers and engineers who want to know how we did it. Just a few weeks we started a blog developer to developer on vGPU and we were delighted with the interest it has generated. Our developers consistently displayed deep technical dives on xenserver.org blogs and we actively welcome comments and questions to our developers mailing list or Q & A section of the site. We also Aore very interested in writing more of these blogs for developers by developers so please make a comment if subjects you as a developer want to know more about!
