* vl: add -object option to create QOM objects from the command lineAnthony Liguori2012-11-161-0/+8
| | | | | | | | | | | This will create a new QOM object in the '/objects' path. Note that properties are set in order which allows for simple objects to be initialized entirely with this option and then realized. This option is roughly equivalent to -device but for things that are not devices. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

* qemu-config: Add new -add-fd command line optionCorey Bryant2012-10-241-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* qemu-options.hx: Change from recommending '?' to 'help'Peter Maydell2012-10-191-21/+17Star
| | | | | | | | | | | | | | | | Update the -help output and documentation so that it recommends 'help' rather than '?' for the various "list valid values for this option" cases. '?' is deprecated (as it can fail confusingly if not quoted), so it's better to steer users towards 'help'. ('?' still works, for backwards compatibility.) This is the -help option part of the change otherwise done in commit c8057f9, since we are now past release 1.2 and free to change our help text without worrying about breaking libvirt.

* add a boot parameter to set reboot timeoutAmos Kong2012-09-261-3/+9
| | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides a way to optionally suppress spurious interrupts, as a workaround for systems described below: Some old operating systems do not handle spurious interrupts well, and qemu tends to generate them significantly more often than real hardware. Examples: - Microport UNIX System V/386 v 2.1 (ca 1987) (The main problem I'm fixing: Without this patch, it panics sporadically when accessing the hard disk.) - AT&T UNIX System V/386 Release 4.0 Version 2.1a (ca 1991) See screenshot in "QEMU Official OS Support List": http://www.claunia.com/qemu/objectManager.php?sClass=application&iId=9 (I don't have this system to test.) - A report about OS/2 boot lockup from 2004 by Hampa Hug: http://lists.nongnu.org/archive/html/qemu-devel/2004-09/msg00367.html (My patch was partially inspired by his.)

* vga: add some optional CGA compatibility hacksMatthew Ogilvie2012-08-241-0/+19
| | | | | | | | | | | | | | | | | | | | | | This patch adds some optional compatibility hacks (default disabled) to allow Microport UNIX to function under qemu. I've tried to structure it to be easy to add more hacks for other old CGA programs, if anyone ever needs them. Microport UNIX System V/386 v 2.1 (ca 1987) tries to program the CGA registers directly with neither the assistance of BIOS, nor with proper handling of EGA/VGA-only registers. Note that it didn't work on real VGA hardware, either (although in that case, the most obvious problems seemed to be out-of-range hsync and/or vsync signalling, rather than the issues in this patch). Eventually real MDA and/or CGA support might provide an alternative to this patch, although a hybrid approach like this patch might still be useful in marginal cases.

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.

* iscsi: Pick default initiator-name based on the name of the VMRonnie Sahlberg2012-08-091-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the iscsi layer to automatically pick a 'unique' initiator-name based on the name of the vm in case the user has not set an explicit iqn-name to use. Create a new function qemu_get_vm_name() that returns the name of the VM, if specified. This way we can thus create default names to use as the initiator name based on the guest session. If the VM is not named via the '-name' command line argument, the iscsi initiator-name used wiull simply be iqn.2008-11.org.linux-kvm If a name for the VM was specified with the '-name' option, iscsi will use a default initiatorname of iqn.2008-11.org.linux-kvm:<name> These names are just the default iscsi initiator name that qemu will generate/use only when the user has not set an explicit initiator name via the commandlines or config files.

* vnc: disable VNC password authentication (security type 2) when in FIPS modePaul Moore2012-08-031-0/+11
| | | | | | | | | | | | | | | | FIPS 140-2 requires disabling certain ciphers, including DES, which is used by VNC to obscure passwords when they are sent over the network. The solution for FIPS users is to disable the use of VNC password auth when the host system is operating in FIPS compliance mode and the user has specified '-enable-fips' on the QEMU command line. This patch causes QEMU to emit a message to stderr when the host system is running in FIPS mode and a VNC password was specified on the commend line. If the system is not running in FIPS mode, or is running in FIPS mode but VNC password authentication was not requested, QEMU operates normally.

* Support 'help' as a synonym for '?' in command line optionsPeter Maydell2012-08-021-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.

| | | | | | | | | | | | | | When using guestfwd=, Qemu only connects the virtual server's TCP port to a single chardev. This is useless in most cases, as we usually want to have more than a single connection from the guest to the outside world. This patch adds a new cmd: target to guestfwd= that allows for execution of a command on every TCP connection.

|/ | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | This enable us to do passthrough equivalent security model on NFS directory. NFS server mostly do root squashing and don't support xattr. Hence we cannot use 'passthrough' or 'mapped' security model Also added "mapped-xattr" security to indicate earlier "mapped" security model Older name is still supported. POSIX rules regarding ctime update on chmod are not followed by this security model. Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.vnet.ibm.com>
* | Add support for net bridgeCorey Bryant2012-02-011-13/+60

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>
