parascsi 是 vmware 中一种高性能的 scsi 控制器。 在此之前，scsi 只包括 "lsilogic", "lsilogicsas", "buslogic"; 而别名为 pvscsi 的 parascsi 没有被包含进来；并且，一个 pci controller只能挂一个 scsi controller， 这会导致如果在一个拥有 pvscsi 的机器上添加普通scsi驱动类型的磁盘，就会替换驱动； 反之亦然。这会导致驱动的 key 不是我们指定的key，并且在添加磁盘的时候替换驱动的 类型有些随意。再者，我们的驱动类型的选择其实并没有暴露给前端。 所以，在寻找相应的controller时，将 parascsi 也纳入 scsi 类型。 尽量避免在创建磁盘的时候做硬件的改动，所以在创建磁盘的时候不区分 scsi 还是 pvscsi，如果两种 controller 均没有，就按照请求的类型创建一个。 此外，在 CloneVM 的时候，如果支持，优先使用 parascsi。

What is Yunion OneCloud?
Yunion OneCloud is an open source unified-IaaS cloud platform.
As its name sugguests, 'Yun' means 'cloud' in Chinese and 'Yunion OneCloud' means to unify many distinct clouds into the one that behaves like an integral cloud platform.
As trends show, the enterprise IT infrastructure in the future would be unavoidably heterogeneous and the public clouds should be the major infrastructure providers for many enterprises. Further, the infrastructure would most likely be prepared for the cloud-native applications running on Kubernetes. Yunion OneCloud is built to provide the cloud architecture for this scenario such that it is the middle layer between the underlying cloud infrustructures and the overlay kubernetes clusters across many clouds.
Many may consider Yunion OneCloud as a multi-cloud management platform (MCMP). Rather, we would view it as an IaaS platform as it does not only manage the resources and services from many clouds, but also hides the differences of underlying technologies and exposes one set of APIs that allow programatically interacting with the compute/storage/networking resources across many clouds.
Yunion OneCloud is working on abstracting APIs for the following resources:
- Compute, including virtual machines, images, etc.
- Storage, including disks, snapshots, object storages, etc.
- Networking, including load balancers, VPC, virtual networks, NAT gateways, security groups, etc.
- Accouting and billing, etc.
- ...
over the following many cloud providers:
- On-premise IT resources, including kvm VM, baremetal, VMware vsphere/ESXi, etc.
- Private clouds, including OpenStack, etc.
- Public clouds, including Aliyun, AWS, Azure, Tencent Cloud, Huawei Cloud, etc.
You are welcome to install and try Yunion OneCloud. Looking forward to your feedback.
