Since we switched from direct host migration scheme to the one, where we connect to the destination and then just pass a FD to a qemu, we have uncovered a qemu bug. Qemu expects migration FD to block. However, we are passing a nonblocking one which results in cryptic error messages like: qemu: warning: error while loading state section id 2 load of migration failed The bug is already known to Qemu folks, but we should workaround already released Qemus. Patch has been originally proposed by Stefan Hajnoczi <stefanha@gmail.com> (cherry picked from commit ceb31795af40f6127a541076b905935ff83e5b11)
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.
