Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.

This introduces a new event type VIR_DOMAIN_EVENT_ID_IO_ERROR This event includes the action that is about to be taken as a result of the watchdog triggering typedef enum { VIR_DOMAIN_EVENT_IO_ERROR_NONE = 0, VIR_DOMAIN_EVENT_IO_ERROR_PAUSE, VIR_DOMAIN_EVENT_IO_ERROR_REPORT, } virDomainEventIOErrorAction; In addition it has the source path of the disk that had the error and its unique device alias. It does not include the target device name (/dev/sda), since this would preclude triggering IO errors from other file backed devices (eg serial ports connected to a file) Thus there is a new callback definition for this event type typedef void (*virConnectDomainEventIOErrorCallback)(virConnectPtr conn, virDomainPtr dom, const char *srcPath, const char *devAlias, int action, void *opaque); This is currently wired up to the QEMU block IO error events * daemon/remote.c: Dispatch IO error events to client * examples/domain-events/events-c/event-test.c: Watch for IO error events * include/libvirt/libvirt.h.in: Define new IO error event ID and callback signature * src/conf/domain_event.c, src/conf/domain_event.h, src/libvirt_private.syms: Extend API to handle IO error events * src/qemu/qemu_driver.c: Connect to the QEMU monitor event for block IO errors and emit a libvirt IO error event * src/remote/remote_driver.c: Receive and dispatch IO error events to application * src/remote/remote_protocol.x: Wire protocol definition for IO error events * src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h, src/qemu/qemu_monitor_json.c: Watch for BLOCK_IO_ERROR event from QEMU monitor |

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.
