[PATCH] virsh: Display vhostuser socket path in domblklist
by dinglimin 09 Sep '21

09 Sep '21

The domblklist command is designed to show a brief information about the blocks of a domain. One piece of information that is shows is "Target "and "Source". Before the modification, the Vhost disk of SPDK is displayed as "-". After the modification, the socket associated with it can be displayed Signed-off-by: dinglimin <dinglimin(a)cmss.chinamobile.com> --- tools/virsh-domain-monitor.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/tools/virsh-domain-monitor.c b/tools/virsh-domain-monitor.c index f7cf82acdf..eb3e0ef11a 100644 --- a/tools/virsh-domain-monitor.c +++ b/tools/virsh-domain-monitor.c @@ -644,7 +644,8 @@ cmdDomblklist(vshControl *ctl, const vshCmd *cmd) "|./source/@dev" "|./source/@dir" "|./source/@name" - "|./source/@volume)", ctxt); + "|./source/@volume" + "|./source/@path)", ctxt); } if (details) { -- 2.18.2

[PATCHv4 0/9] ch: Add Console support
by William Douglas 09 Sep '21

09 Sep '21

This series enables console support in the cloud-hypervisor driver. Cloud-hypervisor only supports a single console or serial device at a time, hence the checks to ensure the domain configuration is only passing one or the other. Changes since v3: * Reset ch monitor's curl handle after a get info request * Improved PTY validation logic * Updated deviceValidateCallback to handle PTY validation * Added error reporting for unexpected PTY json data * Dropped the parallels scanning for PTY * Added a fix for handling deviceValidateCallback failures Changes since v2: * Squashed an additional patch. Changes since v1: * Added missing patch to add the virChrdev device * Added handling for multiple curl WRITEFUNCTION call backs * Added missing free for data.content * Removed redundant console configuration check * Improved handling of pty JSON data to make use of g_autoptr * Squashed two patches William Douglas (9): ch_domain: Add virChrdevs for console support ch_monitor: Make unused function static ch_monitor: Update virCHMonitorGet to handle accept a response ch_monitor: Use virCHMonitorGet to access cloud-hypervisor API ch_monitor: Add pty json builder function ch_process: Handle enabled console devices ch_domain: Allow controller and chr devices ch_driver: Add handler for console API ch_driver: Handle validation failure correctly src/ch/ch_domain.c | 40 +++++++++++++++++++- src/ch/ch_domain.h | 3 ++ src/ch/ch_driver.c | 76 ++++++++++++++++++++++++++++++++++++- src/ch/ch_monitor.c | 91 +++++++++++++++++++++++++++++++++++++++++++-- src/ch/ch_monitor.h | 3 ++ src/ch/ch_process.c | 84 +++++++++++++++++++++++++++++++++++++++++ 6 files changed, 290 insertions(+), 7 deletions(-) -- 2.31.1

[PATCH 00/24] virstoragetest: Re-instate testing of images without backing format
by Peter Krempa 09 Sep '21

09 Sep '21

Most of the series are refactors to make virstoragetest less archaic, the last commit then re-introduces testing of images which don't have backing format recorded in the metadata which can't be formatted using qemu-img any more but have security implications if we'd mishandle them. Peter Krempa (24): virstoragetest: Drop testing of RBD backends via parsing real images virstoragetest: Drop testing of NBD backends via parsing real images testutils: Introduce helper for stripping bulilddir/srcdir from test outputs virstoragetest: Store output of TEST_CHAIN in output files virstoragetest: Remove redundant arguments for chain lookup tests virstoragetest: Rework TEST_LOOKUP* cases to work on fake backing chain virstoragetest: Test backing chain loops with hardcoded images virstoragetest: Use existing directory in the source tree for 'directory' probing tests virstoragetest: Use a pre-formatted QED file for testing backing store extraction virstoragetest: Use pre-formatted file for non-path extraction test virstoragetest: Use preformatted file for testing missing backing store virstoragetest: Use existing file for testing 'raw' image lookup virstoragetest: Convert symlink and relative image testing use preformatted images virstoragetest: Use preformatted qcow2 image for testing relative paths virstoragetest: Unify testing of QCOW2 images with absolute backing virstoragetest: Stop rewriting images in 'mymain' virstoragetest: Don't rewrite the 'qcow2' image virstoragetest: Assume that 'qemu-img' supports '-o compat=' virstoragetest: testPrepImages: Don't reuse 'cmd' pointer virstoragetest: testPrepImages: Use 'qemu-img' to format 'raw' image virstoragetest: testStorageChain: Skip test if filename is NULL virstoragetest: Don't skip the whole test when qemu-img fails to format images virstoragetest: Remove pointless goto from mymain

While looking at users of virCPU.*Free, I found some code that is supposed to deal with Xen < 4.7.

Personally, I feel like all the cases caught by new Clang's -Wunused-but-set-variable behavior were also unnecessarily difficult to read for humans, we should be more obvious when relying purely on side effects of g_auto and the warning is worth keeping.

[PATCH 0/1] qemu: add virtio-blk queue-size option
by Hiroki Narukawa 06 Sep '21

06 Sep '21

Hello, The option "queue-size" in virtio-blk was added in qemu-2.12.0, and default value increased from qemu-5.0.0. However, increasing this value may lead to drop of random access performance. This is configurable value, so we want to use it via libvirt. Sorry, my previous e-mail had wrong CC address that is rejected, please reply to this message and not previous one.

RBD encryption support in libvirt
by Or Ozeri 05 Sep '21

05 Sep '21

Hi, I wanted to get your advice on a patch I'm preparing for libvirt. It touches the code-path that allows using LUKS encryption on top of an RBD image. We recently added LUKS and LUKS2 encryption support in Ceph's librbd. We exposed this in qemu in a recent patch by adding new optional "encrypt" member to BlockdevOptionsRbd. This patch was included in the recent release of qemu 6.1. To enable libvirt users to use librbd encryption, we need libvirt to use this new "encrypt" when it builds the blockdev options for RBD. The interesting question is how to define the libvirt XML syntax that will trigger the use of librbd encryption. My thought was to use the already existing <encryption> tag. In that case, we just need to add a new format VIR_STORAGE_ENCRYPTION_FORMAT_LUKS2 to the enum virStorageEncryptionFormatType. This type will be checked in qemuBlockStorageSourceGetRBDProps. The problem with this approach is that it only works for LUKS2. librbd encryption also supports LUKS1. We want to allow the user to choose between the qemu LUKS implementation and the librbd one. One reason to keep support both is that on the one hand librbd only supports XTS mode. On the other hand, qemu implementation will not support a chain of uniquely encrypted RBD images (each serving as a backing store for the previous one). So we need a way in the XML API to support both implementations. Our current thought is to add a new "engine" attribute to the encryption tag. By default, encryption will use the QEMU LUKS implementation, unless <encryption engine='rbd' ...> is specified. To make this more general, we can have engine='backend' instead of engine='rbd' to denote that the encryption is to be delegated to the backend storage properties (instead of the format properties). This way, the encryption tag will only be parsed in the flow of qemuBlockStorageSourceGetBackendProps, instead of in qemuBlockStorageSourceGetBlockdevProps We'll appreciate any feedback you have on this. Thanks, Or

[libvirt PATCH v2 0/1] Add a PCI/PCIe device VPD Capability
by Dmitrii Shcherbakov 02 Sep '21

02 Sep '21

Add support for deserializing the binary PCI/PCIe VPD format and exposing VPD resources as XML elements in a new nested capability of PCI/PCIe devices called 'vpd'. The VPD format is specified in "I.3. VPD Definitions" in PCI specs (2.2+) and "6.28.1 VPD Format" PCIe 4.0. As section 6.28 in PCIe 4.0 notes, the PCI Local Bus and PCIe VPD formats are binary compatible and PCIe 4.0 merely started incorporating what was already present in PCI specs. Linux kernel exposes a binary blob in the VPD format via sysfs since v2.6.26 (commit 94e6108803469a37ee1e3c92dafdd1d59298602f) which requires a parser to interpret. There are usage scenarios where information such as the board serial number needs to be retrieved from PCI(e) VPD. Projects like Nova can utilize this information for cases which involve virtual interface plugging on SmartNIC DPUs but there may be other scenarios and types of information useful to retrieve from VPD. The fact that the format is binary requires proper parsing instead of substring searching hence the full parser is proposed. Likewise, checksum validation requires proper parsing as well. The patch follows a prior discussion on the mailing list which has additional context about the use-case but a narrower proposal: https://listman.redhat.com/archives/libvir-list/2021-May/msg00873.html https://www.mail-archive.com/libvir-list@redhat.com/msg218165.html The new functionality is mostly contained in virpcivpd with a couple of new functions added to virpci. Additionally, the necessary XML serialization/deserialization and glue code is added to expose the VPD capability to external clients as XML. A new capability flag is added along with a new capability in order to allow for filtering of PCI devices with the VPD capability using virsh: virsh nodedev-list --cap vpd sudo virsh nodedev-dumpxml --device pci_dddd_bb_ss_f In this example having the root uid is required in order to access the vpd sysfs entry, therefore, the nodedev XML output will only contain the VPD capability if virsh is run as root. The capability is treated as dynamic due to the presence of read-write sections in the VPD format per PCI/PCIe specs (the idea being that read-write resource fields may potentially be altered by the DPU OS over time independently from the host OS). Unit tests cover the parser functionality (including many possible invalid cases), in-memory representation as well as XML serialization and deserialization. Manual functional testing was performed with 2 DPUs and several other NIC models which expose PCI(e) VPD. Testing have also been performed for devices that do not have VPD or those that expose a VPD capability but exhibit invalid behavior (I/O errors while reading a sysfs entry). Per the existing guidelines, the implementation relies heavily on glib for various purposes. https://libvirt.org/glib-adoption.html The v2 of the patch is rebased on top of Libvirt 7.7.0 and fixes a couple of minor typos.
