https://bugzilla.redhat.com/show_bug.cgi?id=871452 Okay, so we allow users to 'virsh create' an already existing domain, providing completely different XML than the one stored in Libvirt. Well, as long as name and UUID matches. However, in some drivers the code that handles errors unconditionally removes the domain that failed to start even though the domain might have been persistent. Fortunately, the domain is removed just from the internal list of domains and the config file is kept around. Steps to reproduce: 1) virsh dumpxml $dom > /tmp/dom.xml 2) change XML so that it is still parse-able but won't boot, e.g. change guest agent path to /foo/bar 3) virsh create /tmp/dom.xml 4) virsh dumpxml $dom 5) Observe "No such domain" error Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
