[libvirt] [PATCH 0/7] Support rng backend model 'builtin'
by Han Han 07 Jan '20

07 Jan '20

https://bugzilla.redhat.com/show_bug.cgi?id=1785091 This rng backend is added since QEMU 4.2. It uses getrandom() syscall to generate random instread of external rng source.

[libvirt] Xen + libvirt + TPM
by Arthur Borsboom 07 Jan '20

07 Jan '20

Hello, I am trying to get TPM 2.0 pass through to work with Xen and libvirt, but I can't get it to work. According to the following sites both Xen and libirt have TPM 2.0 support. https://wiki.xen.org/wiki/Virtual_Trusted_Platform_Module_(vTPM) https://libvirt.org/formatdomain.html#elementsTpm However, when I add a TPM device to a VM (by virt-manager), the VM guest XML does contain the TPM configuration, but the VM guest (linux) does not show any TPM device. Also, when looking in /var/log/libvirt/libxl/vmguest.log there is no mention of tpm in the (converted libvirt XML to libxl) vm structure. Is this because libvirt only supports TPM with QEMU? If so, are there any development plans for TPM support with XEN? Is there a workaround for the time being? Best regards, Arthur Borsboom.

[libvirt] [PATCHv2 0/2] Introduce the support of Intel RDT-MBM
by Wang Huaqiang 07 Jan '20

07 Jan '20

This is a followup to Daniel's review in thread https://www.redhat.com/archives/libvir-list/2019-December/msg00978.html. Hi Daniel, In this series, patch 1/2 is trying to fix a bug that using the 64bit, instead of the current 32bit, interface, to hold cache monitor value reported by underlying 64bit counter. In last series, you have suggested of adding a new field such as "cpu.cache.monitor.%zu.bank.%zu.bytes64" for new 64bit counter result, and keep the old but already exported 32bit field, to avoid reporting a truncated cache monitor result to user. But considering the fact that, in reality, CPU cache size will never exceed 4GB in size, it is safe to truccate a 64bit counter to 32 bit since the counter is counting for the cache size that vcpus are using. Change List: v2: * Using old "cpu.cache.monitor.%zu.bank.%zu.bytes" field for cache monitor result, and keeping the interface consistent. * Add 'virsh domstats --memory' document in file 'virsh.rst' Wang Huaqiang (2): util, resctrl: using 64bit interface instead of 32bit for counters Introduce command 'virsh domstats --memory' for reporting memory BW docs/manpages/virsh.rst | 22 +++++- include/libvirt/libvirt-domain.h | 1 + src/libvirt-domain.c | 21 ++++++ src/qemu/qemu_driver.c | 118 ++++++++++++++++++++++++++++++- src/util/virfile.c | 40 +++++++++++ src/util/virfile.h | 2 + src/util/virresctrl.c | 6 +- src/util/virresctrl.h | 2 +- tools/virsh-domain-monitor.c | 7 ++ 9 files changed, 211 insertions(+), 8 deletions(-) -- 2.23.0

[libvirt] [PATCH] ci: Fetch list of available container images dynamically
by Andrea Bolognani 07 Jan '20

07 Jan '20

Any static list of images is destined to become outdated eventually, so let's start generating it dynamically instead. Unfortunately there doesn't seem to be a straightforward way to get Podman/Docker to list all repositories under quay.io/libvirt, so we have to resort to searching and filtering manually; and since the two tools behave slightly differently in that regard, it's more sane to have the logic in a separate shell script than it would be to keep it inline in the Makefile with all the annoying escaping that would entail.

[libvirt] [PATCH] qemu: backup: Move capability check after inactive check

[libvirt] stream does not work in non-block mode with event loop implementation on Fibers
by senid senid 06 Jan '20

06 Jan '20

*libvirt_stream_event_add_callback* creates *passthrough* variable using *rb_ary_new2* and pass it to *virStreamEventAddCallback* at *ext/libvirt/stream.c:272*. After that ruby garbage collector removes this variable (I think because there is no references for *passthrough* in ruby code). https://bugzilla.redhat.com/show_bug.cgi?id=1787914#
