Windows 2012R2 on KVM

Not a fan. Some app requires windows though. I want to stay with KVM on Centos. Then @hballesteros and I figured (after some saint google search) to install windows loading the virtio drives from a cdrom iso over the setup process. 1.

Challenges like multi-tenancy, app security, container registry have been addressed in order to make this work (check on the slides to get more of those) Tessmaster is their own deployment, running on k8s to manage k8s. They … Continue reading eBay, a massive k8s and OpenStack ref case, releasing tessmaster to opensource #os17

Second Generation Cloud #os17
