BOSH and KVM

[gandalf.co...@gmail.com]

Is possible to use BOSH with KVM hosts instead ESX ?

By the way, with a standard BOSH deployment, BOSH automatically span VMs across any hosts in the cluster? For example, if I create a Virtual Datacenter made with 10 servers, is BOSH smart enough to place VMs across multiple servers in the same cluster?

It's more like a bosh-dev question. but i would try to answer it here.

In theory, yes. You can use bosh with openstack as CPI, and configure KVM in openstack. That's an easy way. A hard way is to write KVM CPI, which needs a lot of hacking.

Simple answer is no. Bosh wouldn't know the underlining implementation details of IaaS. That's more like a cluster resource management thing, and it's hard to have an abstraction across various implementation of IaaS, which bosh needs to be support.

From a quick read of bosh source code, it looks like AZs are changable per resource pool; or put another way, one AZ per resource pool.

https://github.com/cloudfoundry/bosh/blob/master/aws_cpi/lib/cloud/aws/cloud.rb#L114-L116

The implementation of select_availability_zone is https://github.com/cloudfoundry/bosh/blob/master/aws_cpi/lib/cloud/aws/cloud.rb#L417-L433

Any guide about writing custom CPI?

I don't use openstack, esx or aws but OpenNebula

... by the way, opennebula has some api with AWS compatibility, probably i can use AWS module

Take a look at https://github.com/cloudfoundry/bosh/blob/master/cpi/lib/cloud.rb for the CPI interface. It is straight-forward. 

Also probably some changes in agent and stemcell builder are needed as well: 

https://github.com/cloudfoundry/bosh/tree/master/agent/lib/agent/infrastructure

https://github.com/cloudfoundry/bosh/tree/master/agent/misc/stemcell/build2/spec

Post in bosh-dev, you'll have more clue :) 

Thanks,

Anfernee

I would post this in https://groups.google.com/a/cloudfoundry.org/forum/m/?fromgroups#!forum/bosh-dev

KVM is a hypervisor. BOSH works with an IaaS API via It's CPI. An open source IaaS you can use on KVM would be openstack. BOSH has a openstack CPI implementation available.

Here is how the setup would go:

Hypervisor (KVM, ESX) ---> IaaS (openstack, vsphere) ---> BOSH ( which deploys Cloud Foundry)

[gandalf.co...@gmail.com]

With 'vSphere' do you mean this?

http://www.vmware.com/products/vsphere-hypervisor/overview.html

is possible to use the free version?

Any plans to support XCP/XenServer as IaaS infrastructure or OCCI API ?
