2018-05-14net: Remove the deprecated "vlan" parameterThomas Huth
It's been marked as deprecated since QEMU v2.9.0, so that should have been enough time for everybody to either just drop unnecessary "vlan=0" parameters, to switch to the modern -device + -netdev syntax for connecting guest NICs with host network backends, or to switch to the "hubport" netdev in case hubs are really wanted instead.

2018-05-09qemu-options: Remove deprecated -no-kvm-irqchipThomas Huth
We've never documented this option in our qemu-doc, so apart from the users that already used the old qemu-kvm fork before, most users should not be aware of this option at all. It's been marked as deprecated in the source code for a long time already, and officially marked as deprecated in the documentation since QEMU v2.10, so it should be fine to remove this now.

2018-03-30qemu-doc: Rework the network options chapter to make "-net" less prominentThomas Huth
"-net" is clearly a legacy option. Yet we still use it in almost all examples in the qemu documentation, and many other spots in the network chapter. We should make it less prominent that users are not lured into using it so often anymore. So instead of starting the network chapter with "-net nic" and documenting "-net <backend>" below "-netdev <backend>" everywhere, all the "-net" related documentation is now moved to the end of the chapter. The new "-nic" option is moved to the beginning of the chapter instead, with a new example that should demonstrate how "-nic" can be used to shortcut "-device" with "-netdev". The examples in this chapter are changed to use the "-device" and "-netdev" options or "-nic" instead of "-net nic -net <backend>". While we're at it, also remove a legacy remark about very old Linux distributions. Also remove the "[...]" from the examples in this chapter since we are not using this ellipsis in any other examples in our docu- mentation.

2018-03-06balloon: Fix documentation of the --balloon parameter and deprecate itThomas Huth
There are two issues with the documentation of the --balloon parameter: First, "--balloon none" is simply doing nothing. Even if a machine had a balloon device by default, this option is not disabling anything, it is simply ignored. Thus let's simply drop this option from the documentation to avoid to confuse the users (but keep the code in vl.c for backward compatibility). Second, the documentation claims that "--balloon virtio" is the default mode, but this is not true anymore since commit 382f074371f7dc32a34. Since that commit, the option also has no real use case anymore, since you can simply use "--device virtio-balloon" nowadays instead. Thus to simplify our complex parameter zoo a little bit, let's deprecate the the parameter now and tell the user to use "--device virtio-balloon" instead.

2018-03-05net: Add a new convenience option "--nic" to configure default/on-board NICsThomas Huth
The legacy "-net" option can be quite confusing for the users since most people do not expect to get a "vlan" hub between their emulated guest hardware and the host backend. But so far, we are also not able to get rid of "-net" completely, since it is the only way to configure on-board NICs that can not be instantiated via "-device" yet. It's also a little bit shorter to type "-net nic -net tap" instead of "-device xyz,netdev=n1 -netdev tap,id=n1". So what we need is a new convenience option that is shorter to type than the full -device + -netdev stuff, and which can be used to configure the on-board NICs that can not be handled via -device yet. Thus this patch now provides such a new option "--nic": It adds an entry in the nd_table to configure a on-board / default NIC, creates a host backend and connects the two directly, without a confusing "vlan" hub inbetween.

2018-02-19mem: add share parameter to memory-backend-ramMarcel Apfelbaum
Currently only file backed memory backend can be created with a "share" flag in order to allow sharing guest RAM with other processes in the host. Add the "share" flag also to RAM Memory Backend in order to allow remapping parts of the guest RAM to different host virtual addresses. This is needed by the RDMA devices in order to remap non-contiguous QEMU virtual addresses to a contiguous virtual address range. Moved the "share" flag to the Host Memory base class, modified phys_mem_alloc to include the new parameter and a new interface memory_region_init_ram_shared_nomigrate.

2018-02-07Add memfd based hostmemMarc-André Lureau
Add a new memory backend, similar to hostmem-file, except that it doesn't need to create files. It also enforces memory sealing. This backend is mainly useful for sharing the memory with other processes. Note that Linux supports transparent huge-pages of shmem/memfd memory since 4.8. It is relatively easier to set up THP than a dedicate hugepage mount point by using "madvise" in /sys/kernel/mm/transparent_hugepage/shmem_enabled. Since 4.14, memfd allows to set hugetlb requirement explicitly. Pending for merge in 4.16 is memfd sealing support for hugetlb backed memory.

2018-01-29net: Allow hubports to connect to other netdevsThomas Huth
QEMU can emulate hubs to connect NICs and netdevs. This is currently primarily used for the mis-named 'vlan' feature of the networking subsystem. Now the 'vlan' feature has been marked as deprecated, since its name is rather confusing and the users often rather mis-configure their network when trying to use it. But while the 'vlan' parameter should be removed at one point in time, the basic idea of emulating a hub in QEMU is still good: It's useful for bundling up the output of multiple NICs into one single l2tp netdev for example. Now to be able to use the hubport feature without 'vlan's, there is one missing piece: The possibility to connect a hubport to a netdev, too. This patch adds this possibility by introducing a new "netdev=..." parameter to the hubports. To bundle up the output of multiple NICs into one socket netdev, you can now run QEMU with these parameters for example: qemu-system-ppc64 ... -netdev socket,id=s1,connect=:11122 \ -netdev hubport,hubid=1,id=h1,netdev=s1 \ -netdev hubport,hubid=1,id=h2 -device e1000,netdev=h2 \ -netdev hubport,hubid=1,id=h3 -device virtio-net-pci,netdev=h3 For using the socket netdev, you have got to start another QEMU as the receiving side first, for example with network dumping enabled: qemu-system-x86_64 -M isapc -netdev socket,id=s0,listen=:11122 \ -device ne2k_isa,netdev=s0 \ -object filter-dump,id=f1,netdev=s0,file=/tmp/dump.dat After the ppc64 guest tried to boot from both NICs, you can see in the dump file (using Wireshark, for example), that the output of both NICs (the e1000 and the virtio-net-pci) has been successfully transfered via the socket netdev in this case.

2018-01-26usb: Remove legacy -usbdevice options (host, serial, disk and net)Thomas Huth
The option have been marked as deprecated since QEMU 2.10, and so far nobody complained that the host, serial, disk and net options are urgently required anymore. So let's now get rid at least of this legacy pile, to simplify the usb code quite a bit. This patch removes the usbdevices host, serial, disk and net. These devices use their own complicated parameter parsing mechanisms, so they are just ugly to maintain, without real benefit for the users (the users can use the corresponding "-device" parameters instead which have the same complexity as the "-usbdevice" devices here). Note that the other rather simple -usbdevice options (mouse, tablet, etc.) are not removed yet (the code is really simple here, so it does not hurt much to keep it), as well as the two devices "braille" and "bt" which are easier to use with -usbdevice than with -device.

2018-01-19hostmem-file: add "align" optionHaozhong Zhang
When mmap(2) the backend files, QEMU uses the host page size (getpagesize(2)) by default as the alignment of mapping address. However, some backends may require alignments different than the page size. For example, mmap a device DAX (e.g., /dev/dax0.0) on Linux kernel 4.13 to an address, which is 4K-aligned but not 2M-aligned, fails with a kernel message like [617494.969768] dax dax0.0: qemu-system-x86: dax_mmap: fail, unaligned vma (0x7fa37c579000 - 0x7fa43c579000, 0x1fffff) Because there is no common approach to get such alignment requirement, we add the 'align' option to 'memory-backend-file', so that users or management utils, which have enough knowledge about the backend, can specify a proper alignment via this option.

2017-12-22i386: hvf: add code base from Google's QEMU repositorySergio Andres Gomez Del Real
This file begins tracking the files that will be the code base for HVF support in QEMU. This code base is part of Google's QEMU version of their Android emulator, and can be found at https://android.googlesource.com/platform/external/qemu/+/emu-master-dev This code is based on Veertu Inc's vdhh (Veertu Desktop Hosted Hypervisor), found at https://github.com/veertuinc/vdhh. Everything is appropriately licensed under GPL v2-or-later, except for the code inside x86_task.c and x86_task.h, which, deriving from KVM (the Linux kernel), is licensed GPL v2-only. This code base already implements a very great deal of functionality, although Google's version removed from Vertuu's the support for APIC page and hyperv-related stuff. According to the Android Emulator Release Notes, Revision 26.1.3 (August 2017), "Hypervisor.framework is now enabled by default on macOS for 32-bit x86 images to improve performance and macOS compatibility", although we better use with caution for, as the same Revision warns us, "If you experience issues with it specifically, please file a bug report...". The code hasn't seen much update in the last 5 months, so I think that we can further develop the code with occasional visiting Google's repository to see if there has been any update. On top of Google's code, the following changes were made: - add code to the configure script to support the --enable-hvf argument. If the OS is Darwin, it checks for presence of HVF in the system. The patch also adds strings related to HVF in the file qemu-options.hx. QEMU will only support the modern syntax style '-M accel=hvf' no enable hvf; the legacy '-enable-hvf' will not be supported. - fix styling issues - add glue code to cpus.c - move HVFX86EmulatorState field to CPUX86State, changing the the emulation functions to have a parameter with signature 'CPUX86State *' instead of 'CPUState *' so we don't have to get the 'env'.

2017-12-20qemu-options qemu-doc: Move "Device URL Syntax" to qemu-docMarkus Armbruster
Commit 0f5314a (v1.0) added section "Device URL Syntax" to qemu-options.hx. It's enclosed in STEXI..ETEXI, thus affects only qemu-options.texi, not --help. It appears as a subsection under section "Invocation". Similarly, qemu.1 has it as a subsection under "OPTIONS". Commit f9dadc9 (v1.1.0) dropped new option -iscsi into the middle of this section. No effect on qemu-options.texi. It appears in --help run together with the "Bluetooth(R) options:" header. Commit c70a01e (v1.5.0) gives it is own heading in --help by moving commit 0f5314a's DEFHEADING(Device URL Syntax:) outside STEXI..ETEXI. Trouble is the heading makes no sense for -iscsi. Move all of the "Device URL Syntax" Texinfo to qemu-doc.texi. Mark it for inclusion in qemu.1 with '@c man begin NOTES'. This turns it into a separate section outside the list of options both in qemu-doc and in qemu.1. There's substantial overlap with the existing qemu-doc section "Disk Images". Mark with a TODO comment. Output of --help will be fixed next.

Commit 43f187a broke --help: it put colons into blank lines. It removed the colon from DEFHEADING(TITLE:) and added it back in the macro expansion of DEFHEADING(TITLE), so hxtool can emit "@subsection TITLE" more easily. Trouble is it's added back even for the blank lines made with DEFHEADING(). Put the colons back where they were before commit 43f187a, and strip them in hxtool instead.

2017-10-13tpm: Added support for TPM emulatorAmarnath Valluri
This change introduces a new TPM backend driver that can communicate with swtpm(software TPM emulator) using unix domain socket interface. QEMU talks to the TPM emulator using QEMU's socket-based chardev backend device. Swtpm uses two Unix sockets for communications, one for plain TPM commands and responses, and one for out-of-band control messages. QEMU passes the data socket to be used over the control channel. The swtpm and associated tools can be found here: https://github.com/stefanberger/swtpm The swtpm's control channel protocol specification can be found here: https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification Usage: # setup TPM state directory mkdir /tmp/mytpm chown -R tss:root /tmp/mytpm /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek # Ask qemu to use TPM emulator with given tpm state directory qemu-system-x86_64 \ [...] \ -chardev socket,id=chrtpm,path=/tmp/swtpm-sock \ -tpmdev emulator,id=tpm0,chardev=chrtpm \ -device tpm-tis,tpmdev=tpm0 \ [...] Signed-off-by: Amarnath Valluri <amarnath.valluri@intel.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Tested-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
