[libvirt] [GSoC] Update ideas page
by Michal Prívozník 07 Jan '19

07 Jan '19

Dear list, Google announced another round of GSoC [1]. The organization applications can be filled mid January next year (~1.5 month to go). Please update our Ideas page [2] if you have any idea for student projects (you do not have to mentor it if you don't feel like it). Similarly, if you want to mentor certain idea and there is no mentor assigned yet, do not hesitate to add yourself there.

[libvirt] [RFC PATCH] maint: let MIN/MAX evaluate only once, on modern compilers
by Eric Blake 04 Jan '19

We might as well take advantage of gcc's extensions for a safer MIN()/MAX() macro. Signed-off-by: Eric Blake <eblake(a)redhat.com> --- RFC because we could also try to fall back to older gcc's typeof(a)_a=(a) when the newer __auto_type _a=(a) is not present, and because I don't know how to properly probe for __auto_type and/or typeof support in clang (I know that clang added __auto_type in 2015, per https://reviews.llvm.org/D12686) I also don't know if we have officially stated that we require gcc/clang (because of attribute((cleanup)), which really cannot be emulated without extensions), or if we still try to allow compilation with other compilers; if we have, I don't know if we have declared a minimum compiler version that we demand (qemu has recently demanded gcc 4.8 or clang 3.4 [branded 5.1 on Apple]). src/util/virutil.h | 20 ++++++++++++++++++-- 1 file changed, 18 insertions(+), 2 deletions(-) diff --git a/src/util/virutil.h b/src/util/virutil.h index 908d8920ec..364e354bcb 100644 --- a/src/util/virutil.h +++ b/src/util/virutil.h @@ -28,10 +28,26 @@ # include <sys/types.h> # ifndef MIN -# define MIN(a, b) ((a) < (b) ?

[libvirt] [PATCH RFC] qemu: caps: invalidate kvm capable qemu binaries on every restart
by Nikolay Shirokovskiy 04 Jan '19

04 Jan '19

If qemu binary exposes kvm then caps depends heavily on host state. We are already check explicitly some host features - kernel version, microcode version, nested flag state. This won't nesserily help if somebody change CPU on host. Let's instead invalidate such caps on every daemon restart. This makes kernel version and microcode version check excessive but nested flag is still need to be checked. Cache invalidating on restart is archived by keeping list of binaries that whose caps cache was validated at least once. If binary in not yet validated and supports kvm then we need to invalidate it's caps cache.

[libvirt] configuration support to allow devices into cgroup devices devices.list inside libvirt_lxc container
by Mohan R 02 Jan '19

02 Jan '19

Hi, I was having trouble with losetup inside libvirt_lxc container. Then I found that <mknod state="on"> will provide CAP_MKNOD capability. Even after enabling CAP_MKNOD in my container, I was not able to do 'losetup' because cgroup's device.list for my container dont have 'rwm' flags for loop devices ('b 7:* rwm' in /sys/fs/cgroup/devices/machine.slice/machine- lxc*.scope/user/*/c1.session/devices.list) Currently I have to manually do echo "b 7:* rwm" into /sys/fs/cgroup/devices/machine.slice/machine-lxc*.scope/devices.allow file before I login into the container in order to use loop devices. It will be useful if we have a way to do this through domain xml rather than manually doing it like what I'm doing now. I looked into rng files, but I'm not able to find a way to define 'b 7:* rwm' in xml. I just want to check with the devs if this is possible already. Otherwise I'll file one improvement bug. I think lxc already have a way to do this through lxc.cgroup.devices.allow Thanks, Mohan R

[libvirt] [PATCH v2 RESEND] qemu: Process RDMA GID state change event
by Yuval Shaia 24 Dec '18

24 Dec '18

This event is emitted on the monitor when a GID table in pvrdma device is modified and the change needs to be propagate to the backend RDMA device's GID table. The control over the RDMA device's GID table is done by updating the device's Ethernet function addresses. Usually the first GID entry is determine by the MAC address, the second by the first IPv6 address and the third by the IPv4 address. Other entries can be added by adding more IP addresses. The opposite is the same, i.e. whenever an address is removed, the corresponding GID entry is removed. The process is done by the network and RDMA stacks. Whenever an address is added the ib_core driver is notified and calls the device driver's add_gid function which in turn update the device. To support this in pvrdma device we need to hook into the create_bind and destroy_bind HW commands triggered by pvrdma driver in guest. Whenever a changed is made to the pvrdma device's GID table a special QMP messages is sent to be processed by libvirt to update the address of the backend Ethernet device. Signed-off-by: Yuval Shaia <yuval.shaia(a)oracle.com> --- Hi, Corresponding qemu commit was merged to master as part of the following patch-set: https://www.mail-archive.com/qemu-devel@nongnu.org/msg583387.html Appreciate if this patch can be reviewed and merged as well.

[libvirt] [PATCH v3] qemu: Process RDMA GID state change event
by Yuval Shaia 23 Dec '18

23 Dec '18

This event is emitted on the monitor when a GID table in pvrdma device is modified and the change needs to be propagate to the backend RDMA device's GID table. The control over the RDMA device's GID table is done by updating the device's Ethernet function addresses. Usually the first GID entry is determine by the MAC address, the second by the first IPv6 address and the third by the IPv4 address. Other entries can be added by adding more IP addresses. The opposite is the same, i.e. whenever an address is removed, the corresponding GID entry is removed. The process is done by the network and RDMA stacks. Whenever an address is added the ib_core driver is notified and calls the device driver's add_gid function which in turn update the device. To support this in pvrdma device we need to hook into the create_bind and destroy_bind HW commands triggered by pvrdma driver in guest. Whenever a changed is made to the pvrdma device's GID table a special QMP messages is sent to be processed by libvirt to update the address of the backend Ethernet device.

[libvirt] [PATCH v5 00/11] update NVDIMM support
by Luyao Zhong 22 Dec '18

22 Dec '18

Hi libvirt experts, There are some gaps between qemu and libvirt, libvirt has not supported several config options about NVDIMM memory while qemu has now, including 'align', 'pmem', 'unarmed'. So these three options is introduced in this patch set. The 'align' and 'unarmed' was renamed to 'alignsize' and 'readonly' in domain xml file for user-friendly definition. Regards, Luyao Zhong Luyao Zhong (11): nvdimm: introduce 'alignsize' element into xml for NVDIMM memory nvdimm: introduce 'pmem' element into xml for NVDIMM memory nvdimm: introduce 'readonly' element into xml for NVDIMM memory qemu_capabilities: introduce QEMU_CAPS_OBJECT_MEMORY_FILE_ALIGN qemu_capabilities: introduce QEMU_CAPS_OBJECT_MEMORY_FILE_PMEM qemu_capabilities: introduce QEMU_CAPS_DEVICE_NVDIMM_UNARMED nvdimm: use DO_TEST_CAPS_LATEST to do nvdimm qemuxml2argvdata test nvdimm: qemu command-line generating for align property nvdimm: qemu command-line generating for pmem property nvdimm: qemu command-line generating for unarmed property nvdimm: update news.xml docs/formatdomain.html.in | 80 +++++++++++++--- docs/news.xml | 9 ++ docs/schemas/domaincommon.rng | 23 ++++- src/conf/domain_conf.c | 57 ++++++++++-- src/conf/domain_conf.h | 3 + src/qemu/qemu_capabilities.c | 16 +++- src/qemu/qemu_capabilities.h | 5 + src/qemu/qemu_command.c | 44 ++++++++- src/qemu/qemu_command.h | 3 +- src/qemu/qemu_hotplug.c | 2 +- .../caps_2.10.0.x86_64.replies | 62 ++++++++----- tests/qemucapabilitiesdata/caps_2.10.0.x86_64.xml | 2 +- .../caps_2.11.0.x86_64.replies | 62 ++++++++----- tests/qemucapabilitiesdata/caps_2.11.0.x86_64.xml | 2 +- tests/qemucapabilitiesdata/caps_2.12.0.aarch64.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.ppc64.xml | 1 + tests/qemucapabilitiesdata/caps_2.12.0.s390x.xml | 1 + .../caps_2.12.0.x86_64.replies | 78 ++++++++++------ tests/qemucapabilitiesdata/caps_2.12.0.x86_64.xml | 3 +- .../qemucapabilitiesdata/caps_2.6.0.x86_64.replies | 46 ++++++--- tests/qemucapabilitiesdata/caps_2.6.0.x86_64.xml | 2 +- .../qemucapabilitiesdata/caps_2.7.0.x86_64.replies | 46 ++++++--- tests/qemucapabilitiesdata/caps_2.7.0.x86_64.xml | 2 +- .../qemucapabilitiesdata/caps_2.8.0.x86_64.replies | 46 ++++++--- tests/qemucapabilitiesdata/caps_2.8.0.x86_64.xml | 2 +- .../qemucapabilitiesdata/caps_2.9.0.x86_64.replies | 62 ++++++++----- tests/qemucapabilitiesdata/caps_2.9.0.x86_64.xml | 2 +- tests/qemucapabilitiesdata/caps_3.0.0.ppc64.xml | 1 + tests/qemucapabilitiesdata/caps_3.0.0.riscv32.xml | 1 + tests/qemucapabilitiesdata/caps_3.0.0.riscv64.xml | 1 + tests/qemucapabilitiesdata/caps_3.0.0.s390x.xml | 1 + .../qemucapabilitiesdata/caps_3.0.0.x86_64.replies | 103 +++++++++++++++------ tests/qemucapabilitiesdata/caps_3.0.0.x86_64.xml | 4 +- tests/qemucapabilitiesdata/caps_3.1.0.ppc64.xml | 2 + .../qemucapabilitiesdata/caps_3.1.0.x86_64.replies | 102 ++++++++++++++------ tests/qemucapabilitiesdata/caps_3.1.0.x86_64.xml | 5 +- .../memory-hotplug-nvdimm-access.args | 31 ------- ...memory-hotplug-nvdimm-access.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-align.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-align.xml | 58 ++++++++++++ .../memory-hotplug-nvdimm-label.args | 31 ------- .../memory-hotplug-nvdimm-label.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-pmem.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-pmem.xml | 58 ++++++++++++ ...mory-hotplug-nvdimm-readonly.x86_64-latest.args | 36 +++++++ .../memory-hotplug-nvdimm-readonly.xml | 58 ++++++++++++ tests/qemuxml2argvdata/memory-hotplug-nvdimm.args | 31 ------- .../memory-hotplug-nvdimm.x86_64-latest.args | 36 +++++++ tests/qemuxml2argvtest.c | 15 ++- .../memory-hotplug-nvdimm-align.xml | 1 + .../memory-hotplug-nvdimm-pmem.xml | 1 + .../memory-hotplug-nvdimm-readonly.xml | 1 + tests/qemuxml2xmltest.c | 3 + 53 files changed, 1047 insertions(+), 339 deletions(-) delete mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-access.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-access.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-align.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-align.xml delete mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-label.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-label.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-pmem.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-pmem.xml create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-readonly.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm-readonly.xml delete mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm.args create mode 100644 tests/qemuxml2argvdata/memory-hotplug-nvdimm.x86_64-latest.args create mode 120000 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-align.xml create mode 120000 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-pmem.xml create mode 120000 tests/qemuxml2xmloutdata/memory-hotplug-nvdimm-readonly.xml -- 2.7.4

[libvirt] [PATCH 0/9] qemu: sav/restore inactive persistent config
by Nikolay Shirokovskiy 21 Dec '18

21 Dec '18

This series address the same issue as seemingly abandomed patch series [1]. Implementation is written from scratch however as I don't see need to introduce new flags for the purpose of this patch series. However I read John's comments and addressed them where applied. The option for not reverting inactive config in case of restoring active persistent domain that Jiri suggested in [2] is new functionality actually and is left for future work. The purpuse of patch series is described in patch 3 "qemu: snapshot: save/restore inactive persistent config": In case of active persistent domain snapshot metadata is not complete. We save only active configuration and on restore use it both for active and inactive configuration. Let's fix it and save and restore both in this case.

[libvirt] [PATCH v2] qemu: Introduce caching whether /dev/kvm is accessible
by Marc Hartmayer 21 Dec '18

21 Dec '18

Introduce caching whether /dev/kvm is usable as the QEMU user:QEMU group. This reduces the overhead of the QEMU capabilities cache lookup. Before this patch there were many fork() calls used for checking whether /dev/kvm is accessible. Now we store the result whether /dev/kvm is accessible or not and we only need to re-run the virFileAccessibleAs check if the ctime of /dev/kvm has changed. Suggested-by: Daniel P.

[libvirt] [PATCH v2 0/2] qemu: fix misc noisy logs for optional storage sources
by Nikolay Shirokovskiy 21 Dec '18

21 Dec '18

John, I still did not add anything to formatdomain.html.in because when I gave this a thought it looks odd to add something like "we don't get stats for missing storage source" - it is obvious because such getting stats is simply not possible. It you feel there is need to add something to the docs then please help me formulate it and we include it in the patch(es) on pushing. Nikolay Diff from v1: ============ - add error logs examples to commit messages - add notices at INFO level of handling optional disks with missing sources in a special way - comment why handling such cases in a special manner in code - check for cold_boot flag in qemuProcessPrepareHostStorage Nikolay Shirokovskiy (2): qemu: don't log error for missing optional storage sources on stats qemu: don't log error for missing optional storage sources on start src/qemu/qemu_domain.c | 9 +++++++++ src/qemu/qemu_domain.h | 3 +++ src/qemu/qemu_driver.c | 14 ++++++++++++++ src/qemu/qemu_process.c | 10 +++++++++- 4 files changed, 35 insertions(+), 1 deletion(-) -- 1.8.3.1

[libvirt] CfP for VHPC ‘19: HPC Virtualization Paper Registration due January 25, 2019 - 14th Virtualization in High-Performance Cloud Computing Workshop@ISC
by VHPC 19 20 Dec '18

20 Dec '18

Please accept our apologies if you receive multiple copies of this Call for Papers ==================================================================== CALL FOR PAPERS 14th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '19) held in conjunction with the International Supercomputing Conference - High Performance, June 16-20, 2019, Frankfurt, Germany. (Springer LNCS Proceedings) ==================================================================== Date: June 20, 2019 Workshop URL: http://vhpc.org Abstract Submission Deadline: January 25, 2019 Springer LNCS, rolling abstract submission Abstract/Paper Submission Link: https://edas.info/newPaper.php?c=25685 Call for Papers Containers and virtualization technologies constitute key enabling factors for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Various virtualization-containerization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; lastly, unikernels provide for many virtualization benefits with a minimized OS/library surface. I/O Virtualization in turn allows physical network interfaces to take traffic from multiple VMs or containers; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology is furthermore enabling virtualization of HPC infrastructures. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC, containers-virtualization and the cloud.

[libvirt] [PULL v3 30/44] hw/i386: Remove deprecated machines pc-0.10 and pc-0.11
