Listing 7.7 contai ns a sample guest configuration file for an HVM guest to be populated from a disc image. Listing 7.

8 contains a sample configuration for an HVM guest to be built from a physical disc. Most of the configuration file in Listing 7.8 is the same as the ISO Image Configuration in Listing 7.

7 (thus this part is omitted), with the exception of the disk parameter, in which we use a physical device (phy: ) instead of a disk image file (tap:aio ). Listing 7.7.

Automated Population with virt-install On Fedora/RHEL sys tems, HVM guests may be easily populated using the included virt-install utility. virt-install asks a series of questions and automatically prepares the guest configuration file according to user input. Listing 7.
