Hello.
Did someone have experience with many-many instances on a single host?
What kind of issues you find on '200 instances' (300) borderline? Any
specific performance issues, stability? (KVM)
I've just start playing with that idea and I see that 150 instances
consume significant amount of CPU for nothing (300%, with 4% per qemu
process), and libvirtd eats for 30% in the peak, plus about 11% for
nova-compute. But this is in the lab conditions.
Any real-life experience?
Thanks!
