OpenVZ inside KVM
Hi all, I want review my infra after 5 months in BETA and now 1 month in production.
We have deployed all our OVZ infra, installing the OVZ kernel on a KVM VPS.
We use Proxmox as a CloudDataCenter software.

Before starting the project, on Q3-2012, I try to find some review, everybody says that I will receive very poor performance... but wait! I'm using SSD disks, so I say that I will try.
Now, 6 months later and around 250 containers running on 6 KVM nodes ( 3 dedicated servers with 2 KVM VPS each one), the performance is Ok and not any problem related stability, (CentOS 6 has full support for VirtIO drivers).
Virtualization inside virtualization = More scalability and more backup options.
Hardware problem? -> I will migrate the KVM VPS, and I'm migrating several containers, yeah!
Maybe you are interested to hear this.
