Does Ali CVM support nested virtualization? General Ali cloud servers do not support secondary virtualization, but Aliyun's elastic bare metal (dragon) servers support virtualization.

Users who need to use virtualization software can purchase elastic bare metal servers, which support third-party virtualization (including but not limited to Xen, KVM, etc.) and AnyStack (including but not limited to OpenStack, ZStack, etc.).

But Ali cloud elastic bare metal server (dragon) configuration is high, the natural price is also very expensive. Suitable for encrypted computing financial business, or extreme computing power of large-scale games.

The cloud server itself is based on virtualization technology, and the cloud service data center has its own advantages.

1. Speed up redeployment. Virtualization can reduce failure problems by redeploying servers using virtual machine snapshots, with little downtime and no impact on users.

2. For better backup, in addition to traditional virtual server backup, enterprises can also create snapshots and backups of all virtual machines. Snapshots can be implemented periodically to deploy the current image on other servers, and snapshots start the machine faster than backups, minimizing downtime.

3. Better testing, virtual environment provides a good testing platform for new servers and applications. When a test goes wrong, you can quickly and easily restore the snapshot to an older version. Enterprises can also easily create test environments that are isolated from end-user access.

4. Improve disaster recovery. Snapshots of current servers and virtual machines can simplify the disaster recovery process. By including backups (if it is the enterprise's network addressing scheme), the enterprise can recreate the data center in any virtual environment.

5. Migrate to the cloud, and virtual machines can be used to create cloud-based infrastructure, which will eventually be transferred to the cloud infrastructure. Through the implementation of this virtualization technology, enterprises can access all connected devices in the cloud.
