[PATCH v2 0/5] Fix crash when reverting/deleting external snapshots
by Peter Krempa 27 Jan '26

27 Jan '26

v2: - modified explanation of why virStorageSourceIsSameLocation was called with NULL - fixed the call to virStorageSourceGetMetadata which caused the NULL deref - fixed permission issue when calling qemu-img if files are owned by root:root after restoring seclabels - improved error message when generating snapshot path fails (not related to original bug, just annoying when I've had a messed up VM) Peter Krempa (5): qemuSnapshotDiskHasBackingDisk: Avoid call of virStorageSourceIsSameLocation with NULL argument qemuSnapshotUpdateBackingStore: Remove stale comment qemuSnapshotDiskHasBackingDisk: Use proper 'max_depth' when calling 'virStorageSourceGetMetadata' virDomainSnapshotDefAssignExternalNames: Improve error message qemuSnapshotUpdateBackingStore: Retry as curent user if qemu-img fails src/conf/snapshot_conf.c | 4 +-- src/qemu/qemu_domain.c | 2 -- src/qemu/qemu_domain.h | 1 + src/qemu/qemu_snapshot.c | 61 ++++++++++++++++++++++++++++------------ 4 files changed, 46 insertions(+), 22 deletions(-) -- 2.52.0

[PATCH] qemu: Connect NVMe devices to PCIe bus
by Akihiko Odaki 26 Jan '26

NVMe has PCIe transport, so connect NVMe devices to PCIe bus instead of classic PCI bus if available.

[PATCH] qemu: introduce the "virtualization" feature
by Roman Bogorodskiy 26 Jan '26

26 Jan '26

The "virt" board in QEMU has a "virtualization" option that is documented like this: virtualization Set ``on``/``off`` to enable/disable emulating a guest CPU which implements the Arm Virtualization Extensions. The default is ``off``. (from system/arm/virt.rst) According to the documentation, the "virtualiaztion" option is related to the "gic-version" option. Specifically, gic version=4 requires virtualization to be enabled. And gic version=max will use version=4 when virtualization is enabled, and 3 when not. Libvirt does not currently model neither gic version "3" nor "max" though. It is also documented for the "vexpress-a(9|15)" boards, where it is also disabled by default: - QEMU defaults to providing a CPU which does not provide either TrustZone or the Virtualization Extensions: if you want these you must enable them with ``-machine secure=on`` and ``-machine virtualization=on`` (system/arm/vexpress.rst). On the command line it looks like: qemu-system-aarch64 -machine type=virt,virtualization=on .. Model it using the "virtualization" element in the "features" section: <features> <virtualization/> </features> Signed-off-by: Roman Bogorodskiy <bogorodskiy(a)gmail.com> --- docs/formatdomain.rst | 4 ++ src/conf/domain_conf.c | 4 ++ src/conf/domain_conf.h | 1 + src/conf/schemas/domaincommon.rng | 5 +++ src/qemu/qemu_command.c | 9 ++++ src/qemu/qemu_validate.c | 1 + ...64-virt-virtualization.aarch64-latest.args | 38 ++++++++++++++++ ...h64-virt-virtualization.aarch64-latest.xml | 45 +++++++++++++++++++ .../aarch64-virt-virtualization.xml | 25 +++++++++++ tests/qemuxmlconftest.c | 2 + 10 files changed, 134 insertions(+) create mode 100644 tests/qemuxmlconfdata/aarch64-virt-virtualization.aarch64-latest.args create mode 100644 tests/qemuxmlconfdata/aarch64-virt-virtualization.aarch64-latest.xml create mode 100644 tests/qemuxmlconfdata/aarch64-virt-virtualization.xml diff --git a/docs/formatdomain.rst b/docs/formatdomain.rst index 04ef319a73..ad74d91950 100644 --- a/docs/formatdomain.rst +++ b/docs/formatdomain.rst @@ -2378,6 +2378,10 @@ are: one IMSIC device present per core), or ``none`` (no support for AIA).

[PATCH v2 0/3] esx: Form URLs containing IPv6 addresses correctly
by Richard W.M. Jones 26 Jan '26

26 Jan '26

v1: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/YRCX… In v2, replace multiple VIR_DEBUG with just one, and add the Reported-by and Reviewed-by tags on the last commit. I'm sure this can't be the only place in libvirt that has to solve this problem (nor the "is this hostname IPv6" problem for that matter), but my searching skills are not good enough to find any other places.

[PATCH] bhyve: improve loader handling on arm64
by Roman Bogorodskiy 26 Jan '26

26 Jan '26

Bhyve on arm64 does not have the bhyveload(8) tool. That means that it cannot be used as a default if the loader is not configured for the domain. To prevent users from getting unusable configurations, handle loader configuration on arm64 like that: - if loader is specified in the domain XML, just use it - if not specified, try to check whether the default uboot loader is available on the system. In case it is, set is as the loader, otherwise fail with the error.

[PATCH 0/3] esx: Form URLs containing IPv6 addresses correctly
by Richard W.M. Jones 26 Jan '26

26 Jan '26

https://issues.redhat.com/browse/RHEL-138300 This bug requires a further fix to allow libvirt to access ESXi servers over IPv6. The way that we constructed the URL (for fetching things from the SDK with curl) was wrong. We formed URLs like: https://1234:56:0:789a:bcde:72ff:fe0a:7baa:443/sdk but with IPv6 we need to put [...] around the IPv6 address. The first patch just adds some debugging so we can see what URLs we are passing to curl. THe second patch is a bit of abstraction so that we're only creating URLs in one place (but two functions). The third detects if the server name is an IPv6 address and adds the square brackets as appropriate. Tested by me, by connecting to an IPv6 VMware server and listing all the domains, and getting the libvirt XML of a single domain. I didn't test all possible operations in depth. The bug was reported by Ming Xie. Rich.

[PATCH v3 0/2] Include test cases for virSocketAddrFormatWithPrefix
by Julio Faracco 23 Jan '26

23 Jan '26

Recently, we removed the masked argument in commit 6f07a8e6 from the respective function. But, in sockettest.c, we don't have any test case to cover this function. This series adds some test cases for virSocketAddrFormatWithPrefix and an extra patch to increase the testFormat debugging info.

[PATCH] Standardize socket family checks with proper macro
by Julio Faracco 23 Jan '26

23 Jan '26

There is a macro called VIR_SOCKET_ADDR_IS_FAMILY that checks the socket family. There are several occurrences of raw checks in libvirt code. This commit just standardizes the socket family checks by using its macro.
