[PATCH rfcv4 00/13] LIBVIRT: X86: TDX support
by Zhenzhong Duan 02 Apr '25

02 Apr '25

Hi, This series brings libvirt the x86 TDX support. * What's TDX? TDX stands for Trust Domain Extensions which isolates VMs from the virtual-machine manager (VMM)/hypervisor and any other software on the platform. To support TDX, multiple software components, not only KVM but also QEMU, guest Linux and virtual bios, need to be updated. For more details, please check link[1]. This patchset is another software component to extend libvirt to support TDX, with which one can start a TDX guest from high level rather than running qemu directly. * Misc As QEMU use a software emulated way to reset guest which isn't supported by TDX guest for security reason. We simulate reboot for TDX guest by kill and create a new one in FakeReboot framework. Complete code can be found at [2], matching qemu code can be found at [3]. There is a 'debug' property for tdx-guest object which isn't in matching qemu[3] yet. I keep them intentionally as they will be implemented in qemu as extention series of [3]. * Test start/stop/reboot with virsh stop/reboot trigger in guest stop with on_poweroff=destroy/restart reboot with on_reboot=destroy/restart * Patch organization - patch 1-4: Support query of TDX capabilities. - patch 5-8: Add TDX type to launchsecurity framework. - patch 9-11: Add reboot support to TDX guest - patch 12-13: Add test and docs TODO: - update QEMU capabilities data in tests, depending on qemu TDX merged beforehand - add reconnect logic in virsh command [1] https://lore.kernel.org/kvm/cover.1708933498.git.isaku.yamahata@intel.com [2] https://github.com/intel/libvirt-tdx/commits/tdx_for_upstream_rfcv4 [3] https://github.com/intel/qemu-tdx/tree/tdx-qemu-upstream-v5 Thanks Zhenzhong Changelog: rfcv4: - add a check to tools/virt-host-validate-qemu.c (Daniel) - remove check of q35 (Daniel) - model 'SocktetAddress' QAPI in xml schema (Daniel) - s/Quote-Generation-Service/quoteGenerationService/ (Daniel) - define bits in tdx->policy and add validating logic (Daniel) - presume QEMU choose split kernel irqchip for TDX guest by default (Daniel) - utilize existing FakeReboot framework to do reboot for TDX guest (Daniel) - drop patch11 'conf: Add support to keep same domid for hard reboot' (Daniel) - add test in tests/ to validate parsing and formatting logic (Daniel) - add doc in docs/formatdomain.rst (Daniel) - add R-B rfcv3: - Change to generate qemu cmdline with -bios - drop firmware auto match as -bios is used - add a hard reboot method to reboot TDX guest rfcv3: https://www.mail-archive.com/devel@lists.libvirt.org/msg00385.html rfcv2: - give up using qmp cmd and check TDX directly on host for TDX capabilities. - use launchsecurity framework to support TDX - use <os>.<loader> for general loader - add auto firmware match feature for TDX A example TDVF fimware description file 70-edk2-x86_64-tdx.json: { "description": "UEFI firmware for x86_64, supporting Intel TDX", "interface-types": [ "uefi" ], "mapping": { "device": "generic", "filename": "/usr/share/OVMF/OVMF_CODE-tdx.fd" }, "targets": [ { "architecture": "x86_64", "machines": [ "pc-q35-*" ] } ], "features": [ "intel-tdx", "verbose-dynamic" ], "tags": [ ] } rfcv2: https://www.mail-archive.com/libvir-list@redhat.com/msg219378.html Zhenzhong Duan (13): tools: Secure guest check for Intel in virt-host-validate qemu: Check if INTEL Trust Domain Extention support is enabled qemu: Add TDX capability conf: expose TDX feature in domain capabilities conf: add tdx as launch security type qemu: Add command line and validation for TDX type qemu: force special parameters enabled for TDX guest Add Intel TDX Quote Generation Service(QGS) support qemu: add FakeReboot support for TDX guest qemu: Support reboot command in guest qemu: Avoid duplicate FakeReboot for secure guest Add test cases for Intel TDX docs: domain: Add documentation for Intel TDX guest docs/formatdomain.rst | 68 ++++ docs/formatdomaincaps.rst | 1 + src/conf/domain_capabilities.c | 1 + src/conf/domain_capabilities.h | 1 + src/conf/domain_conf.c | 312 ++++++++++++++++++ src/conf/domain_conf.h | 75 +++++ src/conf/schemas/domaincaps.rng | 9 + src/conf/schemas/domaincommon.rng | 135 ++++++++ src/conf/virconftypes.h | 2 + src/qemu/qemu_capabilities.c | 36 +- src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 139 ++++++++ src/qemu/qemu_firmware.c | 1 + src/qemu/qemu_monitor.c | 28 +- src/qemu/qemu_monitor.h | 2 +- src/qemu/qemu_monitor_json.c | 6 +- src/qemu/qemu_namespace.c | 1 + src/qemu/qemu_process.c | 75 +++++ src/qemu/qemu_validate.c | 44 +++ ...unch-security-tdx-qgs-fd.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-fd.xml | 30 ++ ...ch-security-tdx-qgs-inet.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-inet.xml | 30 ++ ...ch-security-tdx-qgs-unix.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-unix.xml | 30 ++ ...h-security-tdx-qgs-vsock.x86_64-latest.xml | 77 +++++ .../launch-security-tdx-qgs-vsock.xml | 30 ++ tests/qemuxmlconftest.c | 24 ++ tools/virt-host-validate-common.c | 22 +- tools/virt-host-validate-common.h | 1 + 30 files changed, 1407 insertions(+), 5 deletions(-) create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-fd.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-fd.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-inet.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-inet.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-unix.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-unix.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-vsock.x86_64-latest.xml create mode 100644 tests/qemuxmlconfdata/launch-security-tdx-qgs-vsock.xml -- 2.34.1

[PATCH] virt-aa-helper: delete dynamic files
by Alessandro 01 Apr '25

01 Apr '25

We attempted multiple ways to clean up dynamic files; however, we must preserve user overrides, which requires keeping the file /etc/apparmor.d/libvirt/libvirt-uuid This commit proposes to move user overrides into /etc/apparmor.d/libvirt/libvirt-uuid.local and include it, if present, unconditionally. When we stop the domain, we remove libvirt.uuid and libvirt-uuid.files, whereas we preserve libvirt-uuid.local if present. Applying the patch, it produces the following: root@virt-hv-lab002:/etc/apparmor.d/libvirt# ls -1 libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033* libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033 libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033.files root@virt-hv-lab002:/etc/apparmor.d/libvirt# cat libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033 profile libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033 flags=(attach_disconnected) { #include <abstractions/libvirt-qemu> #include if exists <libvirt/libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033.files> #include if exists <libvirt/libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033.local> } root@virt-hv-lab002:/etc/apparmor.d/libvirt# cat libvirt-e7424556-ffc1-4f6e-bafa-84e66c4dc033.files "/var/log/libvirt/**/testing-9a4be628.log" w, "/var/lib/libvirt/qemu/domain-testing-9a4be628/monitor.sock" rw, "/var/lib/libvirt/qemu/domain-4-testing-9a4be628/*" rw, "/var/run/libvirt/**/testing-9a4be628.pid" rwk, "/var/run/libvirt/**/*.tunnelmigrate.dest.testing-9a4be628" rw, "/var/lib/libvirt/images/testing-9a4be628.qcow2" rwk, "/var/lib/libvirt/images/noble-server-cloudimg-amd64.img" rk, # don't audit writes to readonly files deny "/var/lib/libvirt/images/noble-server-cloudimg-amd64.img" w, "/var/lib/libvirt/images/testing-9a4be628-ds.qcow2" rwk, "/usr/share/OVMF/OVMF_CODE_4M.fd" rk, # don't audit writes to readonly files deny "/usr/share/OVMF/OVMF_CODE_4M.fd" w, "/var/lib/libvirt/qemu/nvram/testing-9a4be628_VARS.fd" rwk, "/dev/vhost-net" rw, "/var/lib/libvirt/qemu/domain-4-testing-9a4be628/{,**}" rwk, "/run/libvirt/qemu/channel/4-testing-9a4be628/{,**}" rwk, "/var/lib/libvirt/qemu/domain-4-testing-9a4be628/master-key.aes" rwk, "/dev/net/tun" rwk, "/dev/userfaultfd" rwk, Fixes: https://gitlab.com/libvirt/libvirt/-/issues/451 Signed-off-by: Alessandro <alessandro(a)0x65c.net> --- src/security/virt-aa-helper.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/security/virt-aa-helper.c b/src/security/virt-aa-helper.c index 034c042..6a1fb85 100644 --- a/src/security/virt-aa-helper.c +++ b/src/security/virt-aa-helper.c @@ -1495,8 +1495,10 @@ main(int argc, char **argv) rc = parserLoad(ctl->uuid); } else if (ctl->cmd == 'R' || ctl->cmd == 'D') { rc = parserRemove(ctl->uuid); - if (ctl->cmd == 'D') + if (ctl->cmd == 'D') { unlink(include_file); + unlink(profile); + } } else if (ctl->cmd == 'c' || ctl->cmd == 'r') { g_autofree char *included_files = NULL; g_auto(virBuffer) buf = VIR_BUFFER_INITIALIZER; @@ -1561,12 +1563,18 @@ main(int argc, char **argv) /* create the profile from TEMPLATE */ if (ctl->cmd == 'c' || purged) { g_autofree char *tmp = NULL; + g_autofree char *tmp_local = NULL; + char *new_tmp = NULL; #if defined(WITH_APPARMOR_3) const char *ifexists = "if exists "; #else const char *ifexists = ""; #endif tmp = g_strdup_printf(" #include %s<libvirt/%s.files>\n", ifexists, ctl->uuid); + tmp_local = g_strdup_printf(" #include %s<libvirt/%s.local>\n", ifexists, ctl->uuid); + new_tmp = g_strconcat(tmp, tmp_local, NULL); + g_free(tmp); + tmp = g_steal_pointer(&new_tmp); if (ctl->dryrun) { vah_info(profile); -- 2.49.0

Release of libvirt-11.2.0
by Jiri Denemark 01 Apr '25

01 Apr '25

The 11.2.0 release of both libvirt and libvirt-python is tagged and signed tarballs are available at https://download.libvirt.org/ https://download.libvirt.org/python/ Thanks everybody who helped with this release by sending patches, reviewing, testing, or providing feedback. Your work is greatly appreciated. * Removed features * Remove support for qemu-6.1 and older Libvirt now requires *qemu-6.2* or newer based on our platform support policy. * New features * qemu: Add new 'image_format' parameter to virDomainSaveParams ``virDomainSaveParams`` now supports an ``image_format`` parameter for specifying the save image format on a per-domain basis. The parameter accepts the same values as the driver-wide ``save_image_format`` setting in ``qemu.conf``. An image format specified via ``virDomainSaveParams`` takes precedence over the driver-wide setting. * qemu: Added guest load averages to the output of virDomainGetGuestInfo This feature will be available with qemu guest agent 10.0 onwards. * qemu: Add support for multiple iothreads for ``virtio-scsi`` controller It's now possible to map multiple iothreads to the ``virtio-scsi`` controller or even map them to specific virtqueues similarly to the ``virtio-blk`` device allowing for better performance in certain scenarios. * qemu: integrate support for VM shutdown on host shutdown It is now possible to instruct the QEMU driver to automatically perform managed save, graceful shutdown, or hard poweroff on running VMs, when a host shutdown is requested. This feature is intended to eventually replace usage of the libvirt-guests script. The new approach improves on the libvirt-guests script, by proactively monitoring logind for a signal that a host shutdown has been requested. It will initiate the chosen action on running guests immediately, allowing shutdown inhibitors to be released sooner. The new solution is also able to iteratively try multiple actions until one of them succeeds in shutting down the VM. Since it must be mutually exclusive with the libvirt-guests script, this feature currently requires a manual opt-in through editing of the /etc/libvirt/qemu.conf configuration file. The libvirt-guests script must be disabled before doing this. * qemu: Add 'sparse' as a new save image format QEMU's ``file`` migration has been supplemented with the new stream format ``mapped-ram``, where RAM pages are mapped directly to offsets in the migration file. ``mapped-ram`` is now supported by augmenting the existing save image formats with the ``sparse`` format. * qemu: Add support for parallel save/restore The ``sparse`` image format can support reading and writing by multiple channels. ``virDomainSaveParams`` and ``virDomainRestoreParams`` now support specifying the number of IO channels used for parallel save and restore. Using multiple channels can reduce the time required to save and restore domains. * virsh: Introduce new hypervisor-cpu-models command Added a new virsh command ``hypervisor-cpu-models``. The command pulls from the existing domcapabilities XML and uses xpath to parse CPU model strings. By default, only models reported as usable by the hypervisor on the host system are printed. A user may specify ``--all`` to also print models which are not supported on the host. * qemu: Introduce os/shim element For secure boot environments where ``<loader/>`` is signed, it may be unfeasible to keep the binary up to date (esp. when revoking certificates contained within). To address that, new ``<shim/>`` element is introduced which allows hypervisor to side load another UEFI binary, which can then contain new certification authorities and/or list of revocations. * ch: Enable SEV SNP support Cloud Hypervisor guests can be now started with SEV SNP enabled. * qemu: Support for Block Disk Along with Throttle Filters Introduce support for multiple throttle groups per block disk in QEMU, enhancing I/O control and performance optimization. This update builds on the existing throttling functionality by allowing more granular control with the ability to assign different throttle groups to multiple block devices, improving shared throttling across devices. * Improvements * qemu: Improved guest agent corner case error reporting The APIs using the guest agent now report two specific error codes aimed at helping management applications/users to differentiate between timeout while libvirt was synchronizing with the guest agent and timeout after a command was already sent. The new error codes are ``VIR_ERR_AGENT_COMMAND_TIMEOUT`` and ``VIR_ERR_AGENT_COMMAND_FAILED``. * qemu: Use common check for shared memory use for ``vhost-user`` network devices Historically libvirt printed only a warning if the ``vhost-user`` network was misconfigured. Since we enforce proper configuration for other device types using ``vhost-user`` it is now enforced also for network devices and prints an actual error on misconfiguration. * Introduce constants for discoverability of entries in bulk stats APIs Libvirt introduced constants exposed by our API description XML which allows discoverability of new entries in typed parameter names returned by ``virConnectGetAllDomainStats``, ``virDomainListGetStats``, and ``virDomainGetGuestInfo``. * qemu: Reflect MAC address change in live domain XML When a guest changes MAC address on one of its vNICs the new MAC address is now visible in the live XML under ``currentAddress`` attribute of ``<mac/>`` element. At the same time, ``VIR_DOMAIN_EVENT_ID_NIC_MAC_CHANGE`` event is emitted so that management applications can update their internal state. * Bug fixes * qemu: attach virtio-mem with CCW address Attaching a virtio-mem device on s390 without an address type now gets a default type CCW address assigned. A specified CCW address is now used for the virtio-mem device instead of getting overwritten by a PCI address. * ch: Various memory leak fixes There were some memory leaks identified in the Cloud Hypervisor driver. They are fixed now. Enjoy. Jirka
