[RFC PATCH 0/5] Implement amd-iommu device to libvirt
by Han Han 27 Sep '24

27 Sep '24

Here is a draft patch series for amd-iommu device. It will implement amd-iommu device and its attributes: intremap, device-iotlb, xtsup. However, its secret device AMDVI-PCI will occupy a PCIe slot and cause VM failed to start: Domain XML: <domain type='kvm'> ... <video> <model type='virtio' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/> </video> <iommu model='amd'/> ... </domain> ➜ ~ virsh create /tmp/fedora.xml error: Failed to create domain from /tmp/fedora.xml error: internal error: QEMU unexpectedly closed the monitor (vm='fedora'): 2024-09-27T07:55:46.132886Z qemu-system-x86_64: -device {"driver":"virtio-vga","id":"video0","max_outputs":1,"bus":"pcie.0","addr":"0x1"}: PCI: slot 1 function 0 not available for virtio-vga, in use by AMDVI-PCI,id=(null) I'll update the series when QEMU fixes the blocker.

[libvirt PATCHv2] ci: adapt to 'dtrace' package split

Fedora has decided to separate dtrace out of the systemtap-sdt-devel package: https://fedoraproject.org/wiki/Changes/Separate_dtrace_package Similarly, these are split in OpenSUSE Tumbleweed, however in a backward-compatbile way: https://build.opensuse.org/package/show/openSUSE:Factory/systemtap Require the new 'systemtap' package mapping, as well as the old 'dtrace'.

[PATCH] cpu_map: Fix SierraForest CPU model
by Jiri Denemark 25 Sep '24

25 Sep '24

The model was defined with two CPU features that cannot be explicitly configured in QEMU (it knows the MSR bits, but there's no name associated with them). The features should have never existed in the CPU map. While removing them from the list of features and existing CPU models is not trivial (to avoid compatibility issues), we can at least fix the SierraForest CPU model added in this release cycle. The rest will be handled later in a separate series.

[RFC PATCH v1 0/6] swtpm: Add support for profiles
by Stefan Berger 24 Sep '24

24 Sep '24

Upcoming libtpms v0.10 and swtpm v0.10 will have TPM profile support that allows to restrict a TPM's provided set of crypto algorithms and commands and through which backwards compatibility and migration from newer versions of libtpms to older ones (up to libtpms v0.9) is supported. For the latter to work it is necessary that the user chooses the right profile. This series adds support for passing a profile choice to swtpm_setup by setting it in the domain XML using the <profile/> XML node. An optional attribute 'remove_disabled' can be set in this node and accepts two values: "check": test a few crypto algorithms (tdes, camellia, unpadded encryption, and others) for whether they are currently disabled due to FIPS mode on the host and remove these algorithms in the 'custom' profile if they are disabled; "fips-host": do not test but remove all potentially disabled crypto algorithms Also extend the documentation but point the user to swtpm and libtpms documentation for further details.
