2012-12-14pseries: Implement PAPR NVRAMDavid Gibson
The PAPR specification requires a certain amount of NVRAM, accessed via RTAS, which we don't currently implement in qemu. This patch addresses this deficiency, implementing the NVRAM as a VIO device, with some glue to instantiate it automatically based on a machine option. The machine option specifies a drive id, which is used to back the NVRAM, making it persistent. If nothing is specified, the driver instead simply allocates space for the NVRAM, which will not be persistent Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>

The external CPU models were removed on QEMU 1.2, and the support for the "cpudef" config sections was documented as deprecated, but the actual removal of the config section was pending. Now that QEMU 1.3 was released, we can finally kill the support for cpudef config sections, and support only the built-in CPU models from target-i386/cpu.c.

Releases of qemu-kvm will be interrupted at qemu 1.3.0. Users should switch to plain qemu releases. To avoid breaking scenarios which are setup with command line options specific to qemu-kvm, port these switches from qemu-kvm to qemu.git. Port drive boot option.

2012-10-29Add USB option in machine optionszhlcindy@gmail.com
When -usb option is used, global varible usb_enabled is set. And all the plaform will create one USB controller according to this variable. In fact, global varibles make code hard to read. So this patch is to remove global variable usb_enabled and add USB option in machine options. All the plaforms will get USB option value from machine options. USB option of machine options will be set either by: * -usb * -machine type=pseries,usb=on Both these ways can work now. They both set USB option in machine options.

2012-10-24qemu-config: Add new -add-fd command line optionCorey Bryant
This option can be used for passing file descriptors on the command line. It mirrors the existing add-fd QMP command which allows an fd to be passed to QEMU via SCM_RIGHTS and added to an fd set. This can be combined with commands such as -drive to link file descriptors in an fd set to a drive: qemu-kvm -add-fd fd=3,set=2,opaque="rdwr:/path/to/file" -add-fd fd=4,set=2,opaque="rdonly:/path/to/file" -drive file=/dev/fdset/2,index=0,media=disk This example adds dups of fds 3 and 4, and the accompanying opaque strings to the fd set with ID=2. qemu_open() already knows how to handle a filename of this format. qemu_open() searches the corresponding fd set for an fd and when it finds a match, QEMU goes on to use a dup of that fd just like it would have used an fd that it opened itself.

2012-09-25add a boot parameter to set reboot timeoutAmos Kong
Added an option to let qemu transfer a configuration file to bios, "etc/boot-fail-wait", which could be specified by command -boot reboot-timeout=T T have a max value of 0xffff, unit is ms. With this option, guest will wait for a given time if not find bootabled device, then reboot. If reboot-timeout is '-1', guest will not reboot, qemu passes '-1' to bios by default. This feature need the new seabios's support. Seabios pulls the value from the fwcfg "file" interface, this interface is used because SeaBIOS needs a reliable way of obtaining a name, value size, and value. It in no way requires that there be a real file on the user's host machine. Signed-off-by: Amos Kong <akong@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-09-05spice: adding seamless-migration option to the command lineYonit Halperin
The seamless-migration flag is required in order to identify whether libvirt supports the new QEVENT_SPICE_MIGRATE_COMPLETED or not (by default the flag is off). New libvirt versions that wait for QEVENT_SPICE_MIGRATE_COMPLETED should turn on this flag. When this flag is off, spice fallbacks to its old migration method, which can result in data loss.

Add a new '[,dump-guest-core=on|off]' option to the '-machine' option. When 'dump-guest-core=off' is specified, guest memory is omitted from the core dump. The default behavior continues to be to include guest memory when a core dump is triggered. In my testing, this brought the core dump size down from 384MB to 6MB on a 2GB guest. Is anything additional required to preserve this setting for migration or savevm? I don't believe so.

2012-06-24PPC: e500: allow users to set the /compatible property via -machineAlexander Graf
Device trees usually have a node /compatible, which indicate which machine type we're looking at. For quick prototyping, it can be very useful to change the contents of that node via the command line. Thus, introduce a new option to -machine called dt_compatible, which when set changes the /compatible contents to its value. Signed-off-by: Alexander Graf <agraf@suse.de>
2012-06-24dt: Add global option to set phandle start offsetAlexander Graf

2012-06-04qemu-option: qemu_opts_create(): use error_set()Luiz Capitulino
This commit converts qemu_opts_create() from qerror_report() to error_set(). Currently, most calls to qemu_opts_create() can't fail, so most callers don't need any changes. The two cases where code checks for qemu_opts_create() erros are: 1. Initialization code in vl.c. All of them print their own error messages directly to stderr, no need to pass the Error object 2. The functions opts_parse(), qemu_opts_from_qdict() and qemu_chr_parse_compat() make use of the error information and they can be called from HMP or QMP. In this case, to allow for incremental conversion, we propagate the error up using qerror_report_err(), which keeps the QError semantics Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>

2011-06-06spice: add SASL supportMarc-André Lureau
Turn on SASL support by appending "sasl" to the spice arguments, which requires that the client use SASL to authenticate with the spice. The exact choice of authentication method used is controlled from the system / user's SASL configuration file for the 'qemu' service. This is typically found in /etc/sasl2/qemu.conf. If running QEMU as an unprivileged user, an environment variable SASL_CONF_PATH can be used to make it search alternate locations for the service config. While some SASL auth methods can also provide data encryption (eg GSSAPI), it is recommended that SASL always be combined with the 'tls' and 'x509' settings to enable use of SSL and server certificates. This ensures a data encryption preventing compromise of authentication credentials. It requires support from spice 0.8.1.
