2014-08-25cpus: Define callback for QEMU "nmi" commandAlexey Kardashevskiy1-2/+2
This introduces an NMI (Non Maskable Interrupt) interface with a single nmi_monitor_handler() method. A machine or a device can implement it. This searches for an QOM object with this interface and if it is implemented, calls it. The callback implements an action required to cause debug crash dump on in-kernel debugger invocation. The callback returns Error**. This adds a nmi_monitor_handle() helper which walks through all objects to find the interface. The interface method is called for all found instances. This adds support for it in qmp_inject_nmi(). Since no architecture supports it at the moment, there is no change in behaviour. This changes inject-nmi command description for HMP and QMP.

2014-08-06backends: Introduce chr-testdevPaolo Bonzini1-1/+2
From: Paolo Bonzini <pbonzini@redhat.com> chr-testdev enables a virtio serial channel to be used for guest initiated qemu exits. hw/misc/debugexit already enables guest initiated qemu exits, but only for PC targets. chr-testdev supports any virtio-capable target. kvm-unit-tests/arm is already making use of this backend. Currently there is a single command implemented, "q". It takes a (prefix) argument for the exit code, thus an exit is implemented by writing, e.g. "1q", to the virtio-serial port. It can be used as: $QEMU ... \ -device virtio-serial-device \ -device virtserialport,chardev=ctd -chardev testdev,id=ctd or, use: $QEMU ... \ -device virtio-serial-device \ -device virtconsole,chardev=ctd -chardev testdev,id=ctd to bind it to virtio-serial port0.

It is necessary to reset RTC interrupt reinjection backlog if guest time is synchronized via a different mechanism, such as QGA's guest-set-time command. Failing to do so causes both corrections to be applied (summed), resulting in an incorrect guest time. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Reviewed-by: Michael S.

2014-06-27char: report frontend open/closed state in 'query-chardev'Laszlo Ersek1-1/+7
In addition to the on-line reporting added in the previous patch, allow libvirt to query frontend state independently of events. Libvirt's path to identify the guest agent channel it cares about differs between the event added in the previous patch and the QMP response field added here. The event identifies the frontend device, by "id". The 'query-chardev' QMP command identifies the backend device (again by "id"). The association is under libvirt's control.

2014-05-19block: optimize zero writes with bdrv_write_zeroesPeter Lieven1-15/+37
this patch tries to optimize zero write requests by automatically using bdrv_write_zeroes if it is supported by the format. This significantly speeds up file system initialization and should speed zero write test used to test backend storage performance.

2014-02-09block: add native support for NFSPeter Lieven1-0/+1
This patch adds native support for accessing images on NFS shares without the requirement to actually mount the entire NFS share on the host. NFS Images can simply be specified by an url of the form: nfs://<host>/<export>/<filename>[?param=value[&param2=value2[&...]]] For example: qemu-img create -f qcow2 nfs://10.0.0.1/qemu-images/test.qcow2 You need LibNFS from Ronnie Sahlberg available at: git://github.com/sahlberg/libnfs.git for this to work. During configure it is automatically probed for libnfs and support is enabled on-the-fly. You can forbid or enforce libnfs support with --disable-libnfs or --enable-libnfs respectively. Due to NFS restrictions you might need to execute your binaries as root, allow them to open priviledged ports (<1024) or specify insecure option on the NFS server. For additional information on ROOT vs. non-ROOT operation and URL format + parameters see: https://raw.github.com/sahlberg/libnfs/master/README Supported by qemu are the uid, gid and tcp-syncnt URL parameters. LibNFS currently support NFS version 3 only. Signed-off-by: Peter Lieven <pl@kamp.de> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
