Currently, the qemuProcessStop tries to open the domain log file and saves the original error afterwards. Then all the cleanup is done after which the error is restored back. This has however one flaw: if opening of the log file fails an error is reported, which results in previous error being overwritten (the useful one, e.g. "PCI device XXXX:XXXX could not be found"). Hence, user sees something like: error: failed to create logfile /var/log/libvirt/qemu/ovirt_usb.log: No such file or directory instead of: error: internal error: Did not find USB device 8644:8003 Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reported-by: Zhou Yimin <zhouyimin@huawei.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.
