2020-10-26machine: remove deprecated -machine enforce-config-section optionPaolo Bonzini1-8/+0
Deprecated since 3.1 and complicates the initialization sequence, remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-10-22Remove deprecated -no-kvm optionThomas Huth1-3/+0
The option has never been mentioned in our documentation, it's been deprecated since years, it's marked with QEMU_ARCH_I386 (which does not make sense anymore since KVM is available on other architectures, too), it does not do anything by default in upstream QEMU (since TCG is the default here anyway), and we're spending too much precious time each year discussing whether it makes sense to keep this option as a nice suger or not... let's finally put an end on this and remove it.

2020-09-16manual: escape backslashes in "parsed-literal" blocksLaszlo Ersek1-54/+54
According to <https://docutils.sourceforge.io/docs/ref/rst/directives.html#parsed-literal>, "inline markup is recognized and there is no protection from parsing. Backslash-escapes may be necessary to prevent unintended parsing". The qemu(1) manual page (formatted with Sphinx 2.2.2) has several overlong lines on my system. A stand-alone backslash at EOL serves as line continuation in a "parsed-literal" block. Therefore, escape the backslashes that we want to appear as such in the formatted documentation.

2020-08-27hw/smbios: add options for type 4 max-speed and current-speedYing Fang1-1/+1
Common VM users sometimes care about CPU speed, so we add two new options to allow VM vendors to present CPU speed to their users. Normally these information can be fetched from host smbios. Strictly speaking, the "max speed" and "current speed" in type 4 are not really for the max speed and current speed of processor, for "max speed" identifies a capability of the system, and "current speed" identifies the processor's speed at boot (see smbios spec), but some applications do not tell the differences.

This patch follows up on Markus comments in the above link. Purpose of this patch: We want to print guest name for errors, warnings and info messages. This was the first of two patches the second being MCE errors targeting a VM with guest name prepended. But in a large fleet we see many other errors that disable a VM or crash it. In a large fleet and centralized logging having the guest name enables identify of owner and customer.

2020-07-03crypto: Add tls-cipher-suites objectPhilippe Mathieu-Daudé1-0/+19
On the host OS, various aspects of TLS operation are configurable. In particular it is possible for the sysadmin to control the TLS cipher/protocol algorithms that applications are permitted to use. * Any given crypto library has a built-in default priority list defined by the distro maintainer of the library package (or by upstream). * The "crypto-policies" RPM (or equivalent host OS package) provides a config file such as "/etc/crypto-policies/config", where the sysadmin can set a high level (library-independent) policy. The "update-crypto-policies --set" command (or equivalent) is used to translate the global policy to individual library representations, producing files such as "/etc/crypto-policies/back-ends/*.config". The generated files, if present, are loaded by the various crypto libraries to override their own built-in defaults. For example, the GNUTLS library may read "/etc/crypto-policies/back-ends/gnutls.config". * A management application (or the QEMU user) may overide the system-wide crypto-policies config via their own config, if they need to diverge from the former. Thus the priority order is "QEMU user config" > "crypto-policies system config" > "library built-in config". Introduce the "tls-cipher-suites" object for exposing the ordered list of permitted TLS cipher suites from the host side to the guest firmware, via fw_cfg. The list is represented as an array of bytes. The priority at which the host-side policy is retrieved is given by the "priority" property of the new object type. For example, "priority=@SYSTEM" may be used to refer to "/etc/crypto-policies/back-ends/gnutls.config" (given that QEMU uses GNUTLS). The firmware uses the IANA_TLS_CIPHER array for configuring guest-side TLS, for example in UEFI HTTPS Boot. [Description from Daniel P.

2020-04-14docs: Improve our gdbstub documentationPeter Maydell1-6/+18
The documentation of our -s and -gdb options is quite old; in particular it still claims that it will cause QEMU to stop and wait for the gdb connection, when this has not been true for some time: you also need to pass -S if you want to make QEMU not launch the guest on startup. Improve the documentation to mention this requirement in the executable's --help output, the documentation of the -gdb option in the manual, and in the "GDB usage" chapter.

This commit contains hand-written fixes for some issues with the autogenerated rST fragments in qemu-options.hx: * Sphinx complains about the UTF-8 art table in the documentation of the -drive option. Replace it with a proper rST format table. * rST does not like definition list entries with no actual definition, but it is possible to work around this by putting a single escaped literal space as the definition line. * The "-g widthxheight" option documentation suffers particularly badly from losing the distinction between italics and fixed-width as a result of the auto conversion, so put it back in again. * The script missed some places that use the |qemu_system| etc macros and need to be marked up as parsed-literal blocks. * The script autogenerated an expanded out version of the contents of qemu-option-trace.texi; replace it with an qemu-option-trace.rst.inc include.

2020-03-03net/filter.c: Add Options to insert filters anywhere in the filter listLukas Straub1-5/+26
To switch the Secondary to Primary, we need to insert new filters before the filter-rewriter. Add the options insert= and position= to be able to insert filters anywhere in the filter list. position should be "head" or "tail" to insert at the head or tail of the filter list or it should be "id=<id>" to specify the id of another filter. insert should be either "before" or "behind" to specify where to insert the new filter relative to the one specified with position.

2020-02-07docs: stop documenting the e1000 NIC model as the defaultDaniel P. Berrangé1-5/+7
The default NIC model for QEMU varies per machine type, and is liable to change across machine type versions. Documenting e1000 NIC as the default for PC/i386 is thus misleading to users at best. In particular the PC q35 machine type switched to use e1000e, but only in machine type versions after 2.11. Rather than try to explain which NIC model is used for each machine type version, remove mention of e1000 as the default, and steer users towards always specifying their desired model.

2020-01-23qemu-block-drivers: Convert to rSTPeter Maydell1-1/+1
The qemu-block-drivers documentation is currently in docs/qemu-block-drivers.texi in Texinfo format, which we present to the user as: * a qemu-block-drivers manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-block-drivers manpage * part of the system/ Sphinx manual This follows the same pattern we've done for qemu-ga and qemu-nbd. We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.

The first machine property to fall is Xen's Intel integrated graphics passthrough. The "-machine igd-passthru" option does not set anymore a property on the machine object, but desugars to a GlobalProperty on accelerator objects. The setter is very simple, since the value ends up in a global variable, so this patch also provides an example before the more complicated cases that follow it.

2019-12-17Remove the core bluetooth codeThomas Huth1-79/+0
It's been deprecated since QEMU v3.1. We've explicitly asked in the deprecation message that people should speak up on qemu-devel in case they are still actively using the bluetooth part of QEMU, but nobody ever replied that they are really still using it. I've tried it on my own to use this bluetooth subsystem for one of my guests, but I was also not able to get it running anymore: When I was trying to pass-through a real bluetooth device, either the guest did not see the device at all, or the guest crashed. Even worse for the emulated device: When running qemu-system-x86_64 -bt device:keyboard QEMU crashes once you hit a key. So it seems like the bluetooth stack is not only neglected, it is completely bitrotten, as far as I can tell. The only attention that this code got during the past years were some CVEs that have been spotted there. So this code is a burden for the developers, without any real benefit anymore. Time to remove it. Note: hw/bt/Kconfig only gets cleared but not removed here yet. Otherwise there is a problem with the *-softmmu/config-devices.mak.d dependency files - they still contain a reference to this file which gets evaluated first on some build hosts, before the file gets properly recreated. To avoid breaking these builders, we still need the file around for some time. It will get removed in a couple of weeks instead.
