Commit 4454a9efc728b91e791b1f14c26ea23a19d57f48 introduced bad behaviour on the VIR_EVENT_HANDLE_ERROR condition. This condition is only hit when an invalid FD is used in poll() (typically due to a double-close bug). The QEMU monitor code was treating this condition as non-fatal, and thus libvirt would poll() in a fast loop forever burning 100% CPU. VIR_EVENT_HANDLE_ERROR must be handled in the same way as VIR_EVENT_HANDLE_HANGUP, killing the QEMU instance. * src/qemu/qemu_monitor.c: Treat VIR_EVENT_HANDLE_ERROR as EOF
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.
