Part II Managing virtual machines with libvirt #Edit source

Virtual Machine Manager's Details view offers in-depth information about the VM Guest's complete configuration and hardware equipment. Using this view, you can also change the guest configuration or add and modify virtual hardware. To access this view, open the guest's console in Virtual Machine Manager and either choose View › Details from the menu, or click Show virtual hardware details in the toolbar.

You can use virsh to configure virtual machines (VM) on the command line as an alternative to using the Virtual Machine Manager. With virsh, you can control the state of a VM, edit the configuration of a VM or even migrate a VM to another host. The following sections describe how to manage VMs by using virsh.

You can enhance the security of your virtual machines with AMD Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP). The AMD SEV-SNP feature isolates virtual machines from the host system and other VMs, protecting the data and code. This feature encrypts data and ensures that all changes with the code and data in the VM are detected or tracked. Since this isolates VMs, the other VMs or the host machine are not affected by threats.

This section explains the steps to enable and use AMD SEV-SNP on your AMD EPYC server with openSUSE Leap 15.7.
