[PATCH v6 0/8] qemu: acpi-generic-initiator support
by Andrea Righi 08 Sep '25

08 Sep '25

= Overview = This patch set introduces support for acpi-generic-initiator devices, supported by QEMU [1]. The acpi-generic-initiator object is required to support Multi-Instance GPU (MIG) configurations on NVIDIA GPUs [2]. MIG enables partitioning of GPU resources into multiple isolated instances, each requiring a dedicated virtual NUMA node definition. = Implementation = This patch set implements the libvirt counterpart to the new QEMU feature, enabling users to configure acpi-generic-initiator objects within libvirt domain XML in an abstracted way, used to configure the GPU partitioning. This includes: - adding a "nodeset" attribute to the <acpi> object to assign the list of virtual NUMA nodes to a PCI device, - resolving the nodeset definitions into the proper QEMU command-line arguments, - ensuring compatibility with existing PCI and NUMA configuration. = Example = - Domain XML: ``` ... <cpu mode='host-passthrough' check='none'> <numa> <cell id='0' cpus='0-15' memory='8388608' unit='KiB'/> <cell id='1' memory='0' unit='KiB'/> <cell id='2' memory='0' unit='KiB'/> <cell id='3' memory='0' unit='KiB'/> <cell id='4' memory='0' unit='KiB'/> <cell id='5' memory='0' unit='KiB'/> <cell id='6' memory='0' unit='KiB'/> <cell id='7' memory='0' unit='KiB'/> <cell id='8' memory='0' unit='KiB'/> </numa> </cpu> ... <devices> ... <hostdev mode='subsystem' type='pci' managed='no'> <source> <address domain='0x0009' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x03' slot='0x00' function='0x0'/> <acpi nodeset='1-8'/> </hostdev> </devices> ``` - Generated QEMU command line options: ``` ... /usr/bin/qemu-system-aarch64 \ ... -object '{"qom-type":"memory-backend-ram","id":"ram-node0","size":8589934592}' \ -numa node,nodeid=0,cpus=0-15,memdev=ram-node0 \ -numa node,nodeid=1 \ -numa node,nodeid=2 \ -numa node,nodeid=3 \ -numa node,nodeid=4 \ -numa node,nodeid=5 \ -numa node,nodeid=6 \ -numa node,nodeid=7 \ -numa node,nodeid=8 \ ... -device '{"driver":"vfio-pci","host":"0009:01:00.0","id":"hostdev0","bus":"pci.3","addr":"0x0"}' -object acpi-generic-initiator,id=gi0,pci-dev=hostdev0,node=1 \ -object acpi-generic-initiator,id=gi1,pci-dev=hostdev0,node=2 \ -object acpi-generic-initiator,id=gi2,pci-dev=hostdev0,node=3 \ -object acpi-generic-initiator,id=gi3,pci-dev=hostdev0,node=4 \ -object acpi-generic-initiator,id=gi4,pci-dev=hostdev0,node=5 \ -object acpi-generic-initiator,id=gi5,pci-dev=hostdev0,node=6 \ -object acpi-generic-initiator,id=gi6,pci-dev=hostdev0,node=7 \ -object acpi-generic-initiator,id=gi7,pci-dev=hostdev0,node=8 ``` = References = [1] https://lore.kernel.org/all/20231225045603.7654-2-ankita@nvidia.com/ [2] https://www.nvidia.com/en-in/technologies/multi-instance-gpu/ ChangeLog v5 -> v6: -

[PATCH 0/1] x86: install modules-load.d file to load msr module
by Hector Cao 08 Sep '25

08 Sep '25

This submission is a follow-up of the discussion (RFC) that was happening at: https://lists.libvirt.org/archives/list/devel@lists.libvirt.org/thread/ADJ4… On x86, libvirt makes use of the API exposed by the msr kernel module to read the MSR (Model Specific Registers) values. On some Linux distros, this module is not loaded by default so libvirt might fail to read the MSR values and falls back to /dev/kvm to obtain these values. KVM might be behind in term of exposing all the values of the MSRs so using /dev/kvm is not ideal. This submission tries to make libvirt deploy the modules-load.d configuration so that linux loads the msr module at next boot. One caveat, libvirt installs only the file and does not trigger the load that is only done at next reboot, it is up to each distro to trigger immediately the load of the module without a reboot.

[PATCH 0/3] A couple improvements when auto-adding PCI controllers
by Laine Stump 08 Sep '25

08 Sep '25

The 1st patch fixes a tiny omission from a feature added several years ago, which slightly improves the error message when you attempt to add a pcie-to-pci-bridge controller to a domain that has no PCIe bus. The 2nd improves that error message a bit more, along with improving some comments in the code. The 3rd eliminates said error message completely when you're adding a pcie-to-pci-bridge controller to a domain that *does* support PCIe, but doesn't currently have an open pcie-root-port to plug in the pcie-to-pci-bridge (by auto-adding another pcie-root-port). The impetus for these was https://issues.redhat.com/browse/RHEL-62032 Laine Stump (3): conf: add forgotten clause to virDomainPCIControllerConectTypeToModel() conf: improve error message when a PCI controller can't be auto-added conf: auto-add a pcie-root-port when needed while plugging in pcie-to-pci-bridge src/conf/domain_addr.c | 43 +++++++++++++++---- .../pcie-root-port-too-many.x86_64-latest.err | 2 +- 2 files changed, 35 insertions(+), 10 deletions(-) -- 2.51.0

[PATCH] esx: Satisfy curl type checks
by Michal Privoznik 08 Sep '25

08 Sep '25

From: Michal Privoznik <mprivozn(a)redhat.com> Since its commit [1] curl now performs type checks on curl_easy_setopt(). Some options expect long but we're passing an int. The fix consists mostly of specifying type of numbers passed to the function. Except for two cases: proxy_type and proxy_port which are stored in a structure of ours (_esxUtil_ParsedUri). These have their types switched from int to long and unsigned long, respectively. 1: https://github.com/curl/curl/commit/79b4e56b3f30dc1ac28a81128a07d27338e5219e Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/esx/esx_stream.c | 2 +- src/esx/esx_util.c | 4 ++-- src/esx/esx_util.h | 4 ++-- src/esx/esx_vi.c | 18 +++++++++--------- 4 files changed, 14 insertions(+), 14 deletions(-) diff --git a/src/esx/esx_stream.c b/src/esx/esx_stream.c index 1439940330..4f3ca09379 100644 --- a/src/esx/esx_stream.c +++ b/src/esx/esx_stream.c @@ -411,7 +411,7 @@ esxStreamOpen(virStreamPtr stream, esxPrivate *priv, const char *url, curl_easy_setopt(streamPriv->curl->handle, CURLOPT_READDATA, streamPriv); } else { curl_easy_setopt(streamPriv->curl->handle, CURLOPT_UPLOAD, 0); - curl_easy_setopt(streamPriv->curl->handle, CURLOPT_HTTPGET, 1); + curl_easy_setopt(streamPriv->curl->handle, CURLOPT_HTTPGET, 1L); curl_easy_setopt(streamPriv->curl->handle, CURLOPT_WRITEFUNCTION, esxVI_CURL_WriteStream); curl_easy_setopt(streamPriv->curl->handle, CURLOPT_WRITEDATA, streamPriv); diff --git a/src/esx/esx_util.c b/src/esx/esx_util.c index 7ee0e5f7c0..8e725ed04f 100644 --- a/src/esx/esx_util.c +++ b/src/esx/esx_util.c @@ -125,8 +125,8 @@ esxUtil_ParseUri(esxUtil_ParsedUri **parsedUri, virURI *uri) *tmp++ = '\0'; - if (virStrToLong_i(tmp, NULL, 10, - &(*parsedUri)->proxy_port) < 0 || + if (virStrToLong_ul(tmp, NULL, 10, + &(*parsedUri)->proxy_port) < 0 || (*parsedUri)->proxy_port < 1 || (*parsedUri)->proxy_port > 65535) { virReportError(VIR_ERR_INVALID_ARG, diff --git a/src/esx/esx_util.h b/src/esx/esx_util.h index 58bc44e744..51f1151eb7 100644 --- a/src/esx/esx_util.h +++ b/src/esx/esx_util.h @@ -40,9 +40,9 @@ struct _esxUtil_ParsedUri { bool noVerify; bool autoAnswer; bool proxy; - int proxy_type; + long proxy_type; char *proxy_hostname; - int proxy_port; + unsigned long proxy_port; char *path; char *cacert; }; diff --git a/src/esx/esx_vi.c b/src/esx/esx_vi.c index d25f819bc5..65e19e179e 100644 --- a/src/esx/esx_vi.c +++ b/src/esx/esx_vi.c @@ -315,13 +315,13 @@ esxVI_CURL_Connect(esxVI_CURL *curl, esxUtil_ParsedUri *parsedUri) } curl_easy_setopt(curl->handle, CURLOPT_USERAGENT, "libvirt-esx"); - curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1); - curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0); - curl_easy_setopt(curl->handle, CURLOPT_FOLLOWLOCATION, 0); + curl_easy_setopt(curl->handle, CURLOPT_NOSIGNAL, 1L); + curl_easy_setopt(curl->handle, CURLOPT_HEADER, 0L); + curl_easy_setopt(curl->handle, CURLOPT_FOLLOWLOCATION, 0L); curl_easy_setopt(curl->handle, CURLOPT_SSL_VERIFYPEER, - parsedUri->noVerify ? 0 : 1); + parsedUri->noVerify ? 0L : 1L); curl_easy_setopt(curl->handle, CURLOPT_SSL_VERIFYHOST, - parsedUri->noVerify ? 0 : 2); + parsedUri->noVerify ? 0L : 2L); curl_easy_setopt(curl->handle, CURLOPT_COOKIEFILE, ""); curl_easy_setopt(curl->handle, CURLOPT_HTTPHEADER, curl->headers); curl_easy_setopt(curl->handle, CURLOPT_READFUNCTION, @@ -386,8 +386,8 @@ esxVI_CURL_Download(esxVI_CURL *curl, const char *url, char **content, curl_easy_setopt(curl->handle, CURLOPT_URL, url); curl_easy_setopt(curl->handle, CURLOPT_RANGE, range); curl_easy_setopt(curl->handle, CURLOPT_WRITEDATA, &buffer); - curl_easy_setopt(curl->handle, CURLOPT_UPLOAD, 0); - curl_easy_setopt(curl->handle, CURLOPT_HTTPGET, 1); + curl_easy_setopt(curl->handle, CURLOPT_UPLOAD, 0L); + curl_easy_setopt(curl->handle, CURLOPT_HTTPGET, 1L); responseCode = esxVI_CURL_Perform(curl, url); } @@ -426,7 +426,7 @@ esxVI_CURL_Upload(esxVI_CURL *curl, const char *url, const char *content) curl_easy_setopt(curl->handle, CURLOPT_URL, url); curl_easy_setopt(curl->handle, CURLOPT_RANGE, NULL); curl_easy_setopt(curl->handle, CURLOPT_READDATA, &content); - curl_easy_setopt(curl->handle, CURLOPT_UPLOAD, 1); + curl_easy_setopt(curl->handle, CURLOPT_UPLOAD, 1L); curl_easy_setopt(curl->handle, CURLOPT_INFILESIZE, strlen(content)); responseCode = esxVI_CURL_Perform(curl, url); @@ -1223,7 +1223,7 @@ esxVI_Context_Execute(esxVI_Context *ctx, const char *methodName, curl_easy_setopt(ctx->curl->handle, CURLOPT_URL, ctx->url); curl_easy_setopt(ctx->curl->handle, CURLOPT_RANGE, NULL); curl_easy_setopt(ctx->curl->handle, CURLOPT_WRITEDATA, &buffer); - curl_easy_setopt(ctx->curl->handle, CURLOPT_UPLOAD, 0); + curl_easy_setopt(ctx->curl->handle, CURLOPT_UPLOAD, 0L); curl_easy_setopt(ctx->curl->handle, CURLOPT_POSTFIELDS, request); curl_easy_setopt(ctx->curl->handle, CURLOPT_POSTFIELDSIZE, strlen(request)); -- 2.49.1

[PATCH] qemu: block: Always enable discard forwarding for 'throttle' filter layer
by Peter Krempa 08 Sep '25

08 Sep '25

From: Peter Krempa <pkrempa(a)redhat.com> Discards ought to be forwarded to the protocol nodes where we control if discard actually happens. Unconditionally enable discard='unmap' for the intermediate layer.
