Methods used to obtain the guide for removing a VM from or adding a VM to a domain
In the FusionCloud desktop solution, the operations for adding a VM to and removing a VM from a domain are the same as those on PCs. Adding a VM to a domain must be performed by the administrator. When a user has logged in to a VM, the user can remove it from the domain and add it to a workgroup. Only the administrator can format data disks. Currently, Huawei does not provide an independent guide for removing a VM from or adding a VM to a domain in the FusionCloud desktop solution.

Whether an account can be bound to a user VM
An account is bound to a user VM during VM creation. When creating a VM, you need to perform the following configuration: When VM group type is set to Full copy, configure the Set assignment type, Add user, and Setting User Group parameters. When VM group type is set to Linked clone and Full memory, configure the Number of VMs and Add User (Group) parameters. After the VM has been created, the account is bound to the VM.

Method used to implement VM encryption (including data disk encryption)
To implement VM disk encryption, deploy encryption and decryption agents on a user VM and use the Intel CPU's AES-IN encryption instructions for hardware acceleration. All user and application data is dynamically encrypted when it is written to the virtual disk (volume) and decrypted when it is read from the virtual disk (volume). The data stored in virtual disk files is in ciphertext, and will not be disclosed even if the physical disk or volume and snapshot files are stolen. Prototype test: About 10% performance compromises.

Methods used to copy files to a VM
You can copy files to a VM in the following ways: 1. Configure a USB port redirection policy and copy the files using USB devices, such as a USB flash drive. 2. Enable the VM's remote desktop function and copy the files. 3. Copy the files in folder sharing mode.

Steps for scanning VM hard disks
You can scan a hard disk as follows: 1. On the taskbar of the VM OS, select Start and enter compmgmt.msc in Search programs and files to go to the Computer Management window. 2. In the navigation tree on the left, expand Storage. 3. Right-click Disk Management and choose Rescan Disks.
