2012-06-04qemu-config: introduce qemu_find_opts_err()Luiz Capitulino
This is like qemu_find_opts(), except that it takes an Error argument. This new function allows for a incremental conversion of code using qemu_find_opts(). Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
2012-06-04qemu-config: find_list(): use error_set()Luiz Capitulino
Note that qemu_find_opts() and qemu_config_parse() need to call error_report() to maintain their semantics on error. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-By: Laszlo Ersek <lersek@redhat.com>
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>

2012-02-17Make -machine/-enable-kvm options merge into a single listPeter Maydell
Make the "machine" option list use list merging, so that multiple -machine arguments (and the -enable-kvm argument) all merge together into a single list. Drop the calls to qemu_opts_reset() which meant that only the last -machine or -enable-kvm option had any effect. This fixes the bug where "-enable-kvm -machine foo" would ignore the '-enable-kvm' option, and "-machine foo -enable-kvm" would ignore the '-machine foo' option.

2012-02-09iSCSI: add configuration variables for iSCSIRonnie Sahlberg
This patch adds configuration variables for iSCSI to set initiator-name to use when logging in to the target, which type of header-digest to negotiate with the target and username and password for CHAP authentication. This allows specifying a initiator-name either from the command line -iscsi initiator-name=iqn.2004-01.com.example:test or from a configuration file included with -readconfig [iscsi] initiator-name = iqn.2004-01.com.example:test header-digest = CRC32C|CRC32C-NONE|NONE-CRC32C|NONE user = CHAP username password = CHAP password If you use several different targets, you can also configure this on a per target basis by using a group name: [iscsi "iqn.target.name"] ... The configuration file can be read using -readconfig.

2012-02-08kvm: Allow to set shadow MMU sizeJan Kiszka
Introduce the KVM-specific machine option kvm_shadow_mem. It allows to set a custom shadow MMU size for the virtual machine. This is useful for stress testing e.g. Only x86 supports this for now, but it is in principle a generic concept for all targets with shadow MMUs.

2011-08-23block: add cache=directsync parameter to -driveStefan Hajnoczi
This patch adds -drive cache=directsync for O_DIRECT | O_SYNC host file I/O with no disk write cache presented to the guest. This mode is useful when guests may not be sending flushes when appropriate and therefore leave data at risk in case of power failure. When cache=directsync is used, write operations are only completed to the guest when data is safely on disk. This new mode is like cache=writethrough but it bypasses the host page cache.

2011-07-29showing a splash picture when startwayne
Added options to let qemu transfer two configuration files to bios: "bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command -boot splash=P,splash-time=T P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit is ms. With these two options, if user invoke qemu with menu=on option, then a splash picture would be showed in a given time. For example: qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000 would make boot.bmp shown as a brand with 5 seconds in the booting up process.

-machine somehow suggests that it selects the machine, but it doesn't. Fix that before this command is set in stone. Actually, -machine should supersede -M and allow to introduce arbitrary per-machine options to the command line.

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.

2011-05-08Introduce -machine command option.Anthony PERARD
This option gives the ability to switch one "accelerator" like kvm, xen or the default one tcg. We can specify more than one accelerator by separate them by a colon. QEMU will try each one and use the first whose works. So, ./qemu -machine accel=xen:kvm:tcg which would try Xen support first, then KVM and finally TCG if none of the other works. By default, QEMU will use TCG. But we can specify another default in the global configuration file.

2010-05-26Add cache=unsafe parameter to -driveAlexander Graf
Usually the guest can tell the host to flush data to disk. In some cases we don't want to flush though, but try to keep everything in cache. So let's add a new cache value to -drive that allows us to set the cache policy to most aggressive, disabling flushes. We call this mode "unsafe", as guest data is not guaranteed to survive host crashes anymore. This patch also adds a noop function for aio, so we can do nothing in AIO fashion.
