Re: [libvirt-users] username and passwd after create VM from XML dump

If you use only libvirt to do a guest clone, then the clone will have the same OS credentials as the original. That's probably not what you want. You seem to be asking about libguestfs - but that's a higher-level application than libvirt, so you may want to migrate your questions to the libguestfs list. http://libguestfs.org/virt-sysprep.1.html gives an overview of the sort of things you can do when prepping a cloned system via libguestfs, such as setting up a known account with a known password. Again, libvirt could care less what passwords your guest OS uses, as passwords are not hardware, so dumpxml is unable to show you that information(well, you COULD use libvirt's virDomainSetMetadata to store custom XML that records that information, and then dumpxml would repeat back the custom XML you associated with the guest - but again, that's something you do as management, and not something libvirt tracks natively). Libguestfs knows how to introspect guest file systems, and may help you create a new password, but if you were careless enough to lose track of what password an existing guest was using, I seriously doubt there is anything that we can do to help you recover that password, at least if it was stored securely by the guest OS. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
