2012-03-30qtest: add test frameworkAnthony Liguori1-0/+8
The idea behind qtest is pretty simple. Instead of executing a CPU via TCG or KVM, rely on an external process to send events to the device model that the CPU would normally generate. qtest presents itself as an accelerator. In addition, a new option is added to establish a qtest server (-qtest) that takes a character device. This is what allows the external process to send CPU events to the device model. qtest uses a simple line based protocol to send the events. Documentation of that protocol is in qtest.c. I considered reusing the monitor for this job. Adding interrupts would be a bit difficult. In addition, logging would also be difficult. qtest has extensive logging support. All protocol commands are logged with time stamps using a new command line option (-qtest-log). Logging is important since ultimately, this is a feature for debugging.

2012-02-10vnc: implement shared flag handling.Gerd Hoffmann1-0/+13
VNC clients send a shared flag in the client init message. Up to now qemu completely ignores this. This patch implements shared flag handling. It comes with three policies: By default qemu behaves as one would expect: Asking for a exclusive access grants exclusive access to the client connecting. There is also a desktop sharing mode which disallows exclusive connects (so one forgetting -shared wouldn't drop everybody else) and a compatibility mode which mimics the traditional (but non-conforming) qemu behavior.

2012-02-09iSCSI: add configuration variables for iSCSIRonnie Sahlberg1-4/+12
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. Example : qemu-system-i386 -drive file=iscsi://127.0.0.1/iqn.ronnie.test/1 -readconfig iscsi.conf Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

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.

2012-02-01Add support for net bridgeCorey Bryant1-13/+60
The most common use of -net tap is to connect a tap device to a bridge. This requires the use of a script and running qemu as root in order to allocate a tap device to pass to the script. This model is great for portability and flexibility but it's incredibly difficult to eliminate the need to run qemu as root. The only really viable mechanism is to use tunctl to create a tap device, attach it to a bridge as root, and then hand that tap device to qemu. The problem with this mechanism is that it requires administrator intervention whenever a user wants to create a guest. By essentially writing a helper that implements the most common qemu-ifup script that can be safely given cap_net_admin, we can dramatically simplify things for non-privileged users. We still support existing -net tap options as a mechanism for advanced users and backwards compatibility. Currently, this is very Linux centric but there's really no reason why it couldn't be extended for other Unixes. A typical invocation would be similar to one of the following: qemu linux.img -net bridge -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper" -net nic,model=virtio qemu linux.img -netdev bridge,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 The default bridge that we attach to is br0. The thinking is that a distro could preconfigure such an interface to allow out-of-the-box bridged networking. Alternatively, if a user wants to use a different bridge, a typical invocation would be simliar to one of the following: qemu linux.img -net bridge,br=qemubr0 -net nic,model=virtio qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0" -net nic,model=virtio qemu linux.img -netdev bridge,br=qemubr0,id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0 -device virtio-net-pci,netdev=hn0,id=nic1 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Richa Marwaha <rmarwah@linux.vnet.ibm.com> Signed-off-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This mode is useful when guests may not be sending flushes when appropriate and therefore leave data at risk in case of power failure.

2011-07-29showing a splash picture when startwayne1-2/+14
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.
