[PATCH libvirt v3 00/11] Support AP card, AP queues and AP matrix
by Shalini Chellathurai Saroja 03 Dec '20

03 Dec '20

Add support for AP card devices, AP queues and AP matrix devices in libvirt node device driver. --- v3: - Modify schema definition of ap-adapter to support hex values alone. - Modify schema definition of ap-domain to support hex values alone. - Verify domain value of AP queue device to be within the supported range during parsing. - Re-organized patches 6 and 10 according to review comment. - Minor changes according to review comments. v2: - The tests included in the patches to detect the node devices (AP card, AP queues and AP matrix) are moved to separate patches. These patches are not divided further due to the following reasons: - The previous patches that add support for node devices in libvirt are not divided further into smaller patches (eg: 53aec799fa31711ffaeacc7ec17ec6d3c2e3cadf). - It would be easier to identify the patches relevant to support AP node devices. - The number of lines in each of these patches are around 125, which is not too much. - Modified according to review comments. - New patch to detect mdev_types capabilty of AP matrix device is added to this patch series.

qemu no-shutdown feature in libvirt
by Luna Xu 03 Dec '20

03 Dec '20

Hi developers, Thanks for developing and maintaining such a great tool. I'm new and I'm trying to use the no-shutdown feature of qemu with libvirt. I've confirmed with the user list that currently there's no such feature in libvirt that supports what I want to do, so I'm posting here and see if anyone is aware of any existing project that can achieve this or anything under development to avoid re-implementing the wheel. Here is what I'm doing on qemu: When I start a VM with the qemu command I can specify the -no-shutdown flag so that my qemu process doesn't quit even if I shutdown the VM from the inside (issue shutdown or halt command inside VM). The VM is shutdown but the qemu process is not killed so that the jobs I submitted before for example backup (drive-backup) can continue to run even after VM gets shutdown by the user, and I'm able to check the status of the job through qmp commands (by communicating with the qemu process). Is anyone aware of any project that is currently implementing this functionality? Thanks for reading. Thanks, Luna

[PATCH] qemu_conf: Fix double free problem for cfg->firmwares
by Tuguoyi 02 Dec '20

02 Dec '20

cfg->firmwares still points to the original memory address after being freed by virFirmwareFreeList(). As cfg get freed, it will be freed again even if cfg->nfirmwares=0 which eventually lead to crash. The patch fix it by setting cfg->firmwares to NULL explicitly after virFirmwareFreeList() returns Signed-off-by: Tuguoyi <tu.guoyi(a)h3c.com> --- src/qemu/qemu_conf.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/qemu/qemu_conf.c b/src/qemu/qemu_conf.c index 83de26a..98593b5 100644 --- a/src/qemu/qemu_conf.c +++ b/src/qemu/qemu_conf.c @@ -832,6 +832,7 @@ virQEMUDriverConfigLoadNVRAMEntry(virQEMUDriverConfigPtr cfg, VIR_AUTOSTRINGLIST fwList = NULL; virFirmwareFreeList(cfg->firmwares, cfg->nfirmwares); + cfg->firmwares = NULL; if (qemuFirmwareFetchConfigs(&fwList, privileged) < 0) return -1; -- 2.7.4 -- Best regards, Guoyi

[libvirt][PATCH v1 0/1] support system default memory policy with numatune
by Luyao Zhong 02 Dec '20

02 Dec '20

Hi libvirt experts, ---------- what does this patch support ---------- This patch seeks the support of system default memory policy when numatune is configured. Before this patch, numatune only has three memory modes: static, interleave and prefered. These memory policies are ultimately set by mbind() system call. Memory policy could be 'hard coded' into the kernel, but none of above policies fit our requirment under this case. mbind() support default memory policy, but it requires a NULL nodemask. So obviously setting allowed memory nodes is cgroups' mission. That means if 'default' mode is specified in numatune, numatune config will be completely cgroups setting, which restricting the memory nodes allowed for each vcpu thread in different cells. <numatune> <memory mode="default" nodeset="1-4,^3" migratable="yes" /> <memnode cellid="0" mode="default" nodeset="1"/> <memnode cellid="2" mode="default" nodeset="2"/> </numatune> Above is current design, we introduce a new "migratable" attribute and a new option "default" for "mode" attribute in numatune. ---------- summary of discussion ---------- But at the beginning in RFC[1], Martin Kletzander and I got a consensus, just introducing a new "migratable" attribute to indicates that we rely on operating system to operate memory policy. <numatune> <memory mode="strict" nodeset="1-4,^3" migratable="yes" /> <memnode cellid="0" mode="strict" nodeset="1"/> <memnode cellid="2" mode="preferred" nodeset="2"/> </numatune> the mode will be ignored, and libvirt will not set those memory policy related configs in qemu command line. Then initial patch got Peter Krempa's comments[2], if I understood it correctly, that means config should not be ignored directly (I just stated in document it will be ignored), it should be rejected in code and output log to lead user correct the config. But when I updated the patch, I found I had to add a new option 'default' for mode attribute since its default value is "strict", if not setting mode it will still be formatted to "strict" at the end. So I sent a RFC[3] again, but unfortunately it sunk into the mail sea. (sorry for the RFC/PATCH title changing) [1] https://www.redhat.com/archives/libvir-list/2020-August/msg00960.html [2] https://www.redhat.com/archives/libvir-list/2020-October/msg00396.html [3] https://www.redhat.com/archives/libvir-list/2020-October/msg01033.html mbind(): https://man7.org/linux/man-pages/man2/mbind.2.html Though we have "migratable" in current implementation, actually we can support this feauture without it since we have "default" mode, so is "migratable" still neccessary?

regression in meson build, AC_PATH_PROG lost
by Olaf Hering 02 Dec '20

02 Dec '20

autoconf allows to specify the path to a runtime binary that is not required during build via an environment variable: AC_PATH_PROG([PARTED], [parted], [], [$LIBVIRT_SBIN_PATH]) meson lacks such essential feature. As a result the package build environment needs to have more packages than necessary installed. This excessive list also pushes libvirt closer to the end of the build dependency chain. Was this considered while the buildsystem was switched to meson? Since meson does not support environment variables it seems the only way to address this is to introduce an option in meson_options.txt for each runtime executable. Will such change be accepted?

[PATCH 00/21] move checks from parse functions to post parse
by Daniel Henrique Barboza 01 Dec '20

01 Dec '20

Hi, This started as a simple NVDIMM change, then I realized there is a Gitlab work item for it [1], so I took the extra mile and did a bit more. I'll copy/paste here the motivation for this kind of change, provided by Cole in [1]: ----- The code that handles domain/VM XML parsing (virDomainDefParseXML in src/domain/domain_conf.c) has various validation checks sprinkled within it. Many of these checks should be moved out of the parse step and into virDomainDefPostParse, so they can be shared by various places in the code that build a domain definition without XML, such as converting from native vmware/virtualbox/xen formats. ----- There are still checks to be moved after this work. If this is accepted I'll update [1] with more details/tips about how to proceed with the remaining checks. Some g_auto* cleanups were done along the way.

[PATCH v2] lxc: Cleanup after failed startup
by Michal Privoznik 01 Dec '20

01 Dec '20

If starting an container fails, the virLXCProcessStop() is called. But since vm->def->id is not set until libvirt_lxc is spawned (the domain's ID is PID of that process), virLXCProcessStop() returns early as virDomainObjIsActive() returns false. But doing so leaves behind resources reserved for the containers during the startup process. Most notably, hostdevs are not re-attached to the host, the domain's transient XML is not removed, etc. To resolve this, virLXCProcessCleanup() is called in this case. However, it is modified to accept @flags which allows caller to run only specific cleanups (depending how far in container creation the failure occurred). There is plenty of cleanups which don't need this guard because either they detect a NULL pointer or try to release an unique resource.
