[PATCH] tests: validate an XML config with USB vendor/product set
by Daniel P. Berrangé 01 Jul '25

01 Jul '25

From: Daniel P. Berrangé <berrange(a)redhat.com> The USB vendor/product is usually translated into a device/bus at startup using the hostdev logic. We don't run the latter in the unit test suite, but we can fake it by hardcoding a translation. This demonstrates that we format the command line with the normal device/bus properties, even when vendor/product is set. Signed-off-by: Daniel P.

[PATCH] tls: Don't require 'keyEncipherment' to be enabled altoghther
by Peter Krempa 01 Jul '25

01 Jul '25

From: Peter Krempa <pkrempa(a)redhat.com> Key encipherment is required only for RSA key exchange algorithm. With TLS 1.3 this is not even used as RSA is used only for authentication. Since we can't really check when it's required ahead of time drop the check completely. GnuTLS will moan if it will not be able to use RSA key exchange. In commit 11867b0224a2 I tried to relax the check for some eliptic curve algorithm that explicitly forbid it. Based on the above the proper solution is to completely remove it.

Release of libvirt-11.5.0
by Jiri Denemark 01 Jul '25

01 Jul '25

The 11.5.0 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 * qemu: Don't accept VIR_DUMP_LIVE flag in virDomainCoreDumpWithFormat() Unfortunately, QEMU always pauses vCPUs when doing a core dump. Therefore, there is no way for Libvirt to honor VIR_DUMP_LIVE flag semantics. Instead of silently pretending the flag works, an appropriate error is now reported. * New features * vmx: Add support for reporting NVMe disks in the domain XML * qemu: Add support for NVMe disks NVMe disks can now be emulated by using an ``nvme`` bus, but require a serial due to the hypervisor:: <target dev='nvme0n1' bus='nvme'/> <serial>qwertyuiop</serial> Multiple disks can be represented as different namespaces on the same controller, but they cannot have a different serial number due to the fact that it is the controller which ultimately has the serial number attached to it, but for ease of use it is automatically copied from the disk serial. * esx: Add support for specifying alternative CA bundle for remote peer verification Users can now use ``cacert`` parameter in the URI to specify a file path with CA certificate(s) that will be used for remote peer certificate validation. * qemu: add support for AMD IOMMU device The ``amd`` model for the ``<iommu>`` device is now supported. New attributes ``passtrhough`` and ``xtsup`` are also supported for this model. * Improvements * Include supported console types in domain capabilities Domain capabilities now include information about supported console types, such as:: <console supported='yes'> <enum name='type'> <value>pty</value> <value>tcp</value> </enum> </console> * virsh: Add waiting for domain state via ``virsh await`` The new helper command ``virsh await`` simplifies waiting on domain state which is normally announced via events. Currently two waiting conditions are implemented: ``domain-inactive``, and ``guest-agent-available``. * Bug fixes * qemu: Be more forgiving when acquiring QUERY job when formatting domain XML Since ``libvirt-11.0.0`` the ``virDomainGetXMLDesc()`` API used to format domain XML acquires QUERY job. But this caused a regression when the API might timeout for incoming migration. This is now fixed. * qemu: Fix shared filesystem detection on nonexistent paths Since ``libvirt-11.1.0`` nonexistent paths within directories marked as shared filesystem (via the ``shared_filesystems`` option in ``qemu.conf`` would not be properly detected as being on a shared filesystem. * qemu: Properly emulate USB cdrom device CD-ROM devices on USB bus are now properly emulated as such which was not the case since libvirt switched to the modern qemu commandline sytnax for storage backends. Enjoy. Jirka

pci-hole64-size on q35 questions
by mitchell.augustin＠canonical.com 30 Jun '25

30 Jun '25

Hi, I'm trying to get a better understanding of how libvirt VMs interact with the default QEMU setting for pci-hole64-size on q35 hosts, to assess why my libvirt VMs behave differently from a similarly configured lxd VM. As I understand, both libvirt and lxd are using qemu q35 VMs under the hood, and both are inheriting their pci-hole64-size from qemu's default setting (correct me if that's wrong), but in my tests, I'm getting different behavior from them. I know lxd is probably out of scope from the libvirt project perspective, so consider this more of a libvirt question w/ some added lxd context. All of this is on a DGX B200 host, which contains large (~180GB VRAM) GPUs. With libvirt/virt-install, I created a q35 virtual machine with CPU host passthrough and 1 or more GPUs passed-through via --host-device. Without additional modifications, this works as expected, and I can initialize the GPU driver in the VM and run nvidia-smi. With lxd (which creates a q35 virtual machine with CPU host passthrough by default), I attached 1 GPU via "lxc config device add passthroughtest gpu gpu pci=1b:00.0". On that machine, the pci-hole64-size is too small by default, since I see these in my dmesg: [ 1.099110] pci 0000:00:01.5: bridge window [mem size 0x6000000000 64bit pref]: can't assign; no space [ 1.120274] pci 0000:00:01.5: bridge window [mem size 0x6000000000 64bit pref]: can't assign; no space [ 1.183281] pci 0000:06:00.0: BAR 2 [mem size 0x4000000000 64bit pref]: can't assign; no space [ 1.186320] pci 0000:06:00.0: BAR 0 [mem size 0x04000000 64bit pref]: can't assign; no space [ 1.189340] pci 0000:06:00.0: BAR 4 [mem size 0x02000000 64bit pref]: can't assign; no space and I cannot initialize the GPU driver since the BARs weren't mapped correctly. When I apply a larger hole size to my lxd VM via `lxc config set passthroughtest raw.qemu=' -global q35-pcihost.pci-hole64-size=8192G'`, I don't see any "can't assign; no space" messages, and the driver works as expected. My question about libvirt is - where (if at all) does libvirt interact with qemu's pci-hole64-size value? If libvirt does not automatically do something functionally similar to changing the hole size like I need to do above for lxd, and is in fact just using a qemu default value, is there some other related interaction happening in libvirt that might explain why my libvirt VMs don't require a manual change to pci-hole64-size, despite the fact that the relevant parts of the underlying qemu machine should be the same?

[PATCH v3] remote/stream-event: Fix a memory leak in remoteStreamCallbackFree()
by liu.xuemei1＠zte.com.cn 30 Jun '25

30 Jun '25

From: Liu Song <liu.song13(a)zte.com.cn> The ff callback is never called in remoteStreamCallbackFree() because cbdata->cb can not be NULL. This causes a leak of 'cbdata->opaque'.
