[PATCH] spec: Fix 'obsoletes' for 'libvirt-daemon-driver-storage-zfs'
by Peter Krempa 24 Nov '25

24 Nov '25

From: Peter Krempa <pkrempa(a)redhat.com> On Fedora 43 and newer the 'fuse-zfs' package was removed. Commit bd30147e740 added an 'Obsoletes' directive so that the storage driver core package will update properly but hardcoded the obsoleted version as 11.4 (when the change was comitted) similarly to the old sheepdog/rbd packages. Unfortunately that doesn't work if the sub-package removal happened based on an external dependancy, rather than complete removal of said module in libvirt. If users have e.g. virt-preview repos enabled they'll get libvirt-11.9 currently installed, but the obsoleted version is just 11.4, thus upgrades to Fedora 43 with virt-preview are broken. Fix this by obsoleting everything up to the current build.

[PATCH] src: cap the data size in stream I/O functions
by Daniel P. Berrangé 24 Nov '25

24 Nov '25

From: Daniel P. Berrangé <berrange(a)redhat.com> The main stream I/O functions have a design flaw in that they accept 'size_t' as the input data length, while intending to return the amount actually processed in an 'int'. Fortunately all functions explicitly document that less data may be processed than requested, and with the remote driver data cap we will never get anywhere near exceeding an 'int' even on 32-bit. For sanity, however, lets explicitly cap the data size in the public API to fix the design flaw. Signed-off-by: Daniel P.

[RFC v2 0/5] cover: RFE libvirt secret encryption on disk
by Arun Menon 24 Nov '25

24 Nov '25

Libvirt secrets are stored unencrypted on the disk. With this series we want to start encrypting the secrets. 1. Introduce the GnuTLS decryption wrapper functions that work exact opposite to the encryption wrappers. 2. Add a new service called virt-secrets-init-encryption, that is linked to the virtsecretd service. virtsecretd service only starts after the new service generates a random encryption key. 3. Add a new secrets.conf configuration file that helps user to set a. secrets_encryption_key - allows the user to specify the encryption key file path, in case the default key is not to be used. b. encrypt_data - set to 0 or 1. If set to 1, then the newly added secrets will be encrypted. 4. Add functionality to store the encryption scheme (none, aes256cbc, etc.) to the disk. This will be helpful during service restarts or migrating from an older version. Depending on the scheme, the secrets will be reloaded to the daemon. If no scheme is present in the xml configuration, then the secrets will be stored/loaded in the default base64 encoded format. 5. Once we have the encryption key, and a reliable way to tell the daemon what encryption scheme the secret object is using, we can encrypt the secrets on disk and store them in <uuid>.<encryption_scheme> format. It is important to note that if the encryption key is changed between restarts, then the respective secret will not be loaded by the driver. This is a sincere attempt to improve upon the already submitted patch https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/KE6G… Resolves: https://issues.redhat.com/browse/RHEL-7125 --- Changes in v2: - Corrected the encryption key length check. It should be 32. - Added a new patch that introduces the encryption scheme attribute. This will help us identify which secrets are encrypted. - A new systemd unit service file added that starts before virtsecretd, helping us to construct a random encryption key and pass it to the virtsecretd service. - Parsing logic of secrets.conf moved to a separate file. - Spec file changes, augeas.

[PATCH v2 0/5] qemu: Implement support for iommufd
by Nathan Chen 22 Nov '25

22 Nov '25

Hi, This is a follow up to the first patch series [0] for using iommufd to propagate DMA mappings to the kernel for VM-assigned host devices in a qemu VM. We add a new 'iommufd' attribute for hostdev devices to be associated with the iommufd object. For instance, specifying the iommufd object and associated hostdev in a VM definition: <devices> ... <hostdev mode='subsystem' type='pci' managed='no'> <driver iommufd='yes'/> <source> <address domain='0x0009' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x15' slot='0x00' function='0x0'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='no'> <driver iommufd='yes'/> <source> <address domain='0x0019' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x16' slot='0x00' function='0x0'/> </hostdev> ... </devices> This would get translated to a qemu command line with the arguments below. Note that libvirt will open the /dev/iommu and VFIO cdev, passing the associated fd number to qemu: -object '{"qom-type":"iommufd","id":"iommufd0","fd":"24"}' \ -device '{"driver":"vfio-pci","host":"0009:01:00.0","id":"hostdev0","iommufd":"iommufd0","fd":"22","bus":"pci.21","addr":"0x0"}' \ -device '{"driver":"vfio-pci","host":"0019:01:00.0","id":"hostdev1","iommufd":"iommufd0","fd":"25","bus":"pci.22","addr":"0x0"}' \ Note that when Libvirt launches the qemu process as an unprivileged user, i.e. libvirt-qemu, it is bound by the RLIMIT_MEMLOCK limit calculated based on how much RAM is assigned to the VM. IOMMUFD's unified memory accounting causes ENOMEM errors for large device BARs that exceed the process memlock limit. VFIO without IOMMUFD does not check device memory against the limit and therefore does not show this behavior. To work around the issue, we can specify CAP_IPC_LOCK=ep capability for the qemu binary to bypass the RLIMIT_MEMLOCK limit. I am working on a long-term fix in the kernel to mark device memory regions so they do not count against the RLIMIT_MEMLOCK limit for how much memory can be locked/pinned, as I/O device BARs do not consume host RAM.
