Create a Guest Virtual Machine

Can I name a guest "ose36.master", or "environment-name.host-in-environment-name"?. It would be useful in virsh list.

Virtualization host storage and host-level networking must be configured as a prerequisite to creating guest virtual machines. Once storage pools and storage volumes are made available, and the networking is configured, guest virtual machines can be created with

virt-install

If the XML definition of a virtual machine is available, it can be created with:

virsh define
