Libvirt native C API and daemons
7eabd5503e
A possible fix to issue: http://www.redhat.com/archives/libvir-list/2014-August/thread.html#00227 While doing migration on KVM host, found problem sometimes: VM is already running on the target host and disappears from source host, but 'virsh migrate' command line hangs, cannot exit normally. If pressing "ENTER" key, it will exit. The code hangs at tools/virsh-domain.c: cmdMigrate ->vshWatchJob->poll(): poll() is trying to select pipe_fd, which is used to receive message from doMigrate thread. In debugging, found that doMigrate finishes and at the end it does call safewrite() to write the retval ('0' or '1') to pipe_fd, and the write is completed. But cmdMigrate poll() cannot get the event. If pressing "ENTER" key, poll() can get the event and select pipe_fd, then command line can exit. In current code, authentication thread which is called by vshConnect will use stdin, and at the same time, in cmdMigrate main process, poll() is listening to stdin, that probably affect poll() to get pipe_fd event. Better to move authentication before vshWatchJob. With this change, above problem does not exist. Signed-off-by: Chunyan Liu <cyliu@suse.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.
