The Physical cpu core is 4*2*2=16 , by default, physical cpu: vcpu is
16:1, you can change the rate.
so you have 16*16=256 core.
the memery
the memery is 96*1.5=144G
now you would know support how many vm. seem you need modify the quota, one
host seem have 16vm limit.

Hi Vladimir,
You might also need to check the flags given in nova.conf for
virtual-memory, virtual-cpu to physical-memory, physical-cpu mapping. If
not specified in nova.conf, default value is taken for them. You can have a
look at table 5.22 on this link:-

That depends on how big the VM is, and what over subscription rate you're
running out.
Generally RAM is going to be your limiting factor, it is fairly easy to over
subscribe CPU, and if you're disk is really unlimited, that isn't going to stop
you either.
Assuming you're not oversubscribing RA
Hello!
I'm starting to deploy a private cloud on OpenStack! As the hypervisor
I use nova+KVM on Centos 6.4.
Tell me how to count how many virtual machines can be placed on a single
KVM node.
How to count the number of virtual machines on single node to get
everything working perfectly?
