All, This is my first time posting, I apologize in advance if it is too much of a "newbie" question I am working on a project with libvirt and want to use some of the features in the 0.9.4 release. The first platform I wanted to test this on is RHEL 5.7. I have d/l libvirt and compiled but have the following questions 1) RHEL 5.7 ships with libvirt version, 0.8.2-22. I am guessing that I can not simple overwrite the existing files with the files from 0.9.4. Is there a way to upgrade to 0.9.4? Do I need to build an rpm so that the version is properly reported in the rpm db? I am also guessing some of the other packages the rely on libvirt may no longer work. In addition, I would imagine RH does not support doing this. To summarize, can the lbivrit on RHEL be upgraded and if so does anyone have any info they can point me to? 2) If there is not a way to update RHEL, is there a different distro CentOS, Ubuntu, Fedora that is a better choice to test my project on? 3) I am also guessing if my project is using API's that are not in 0.8.2-22 but are in 0.9.4., I will not be able to connect remotely to the RHEL server and have them pull the data correctly. For example, I want to use virDomainGetMemoryParameters. Thanks in advance. Keith
