[PATCH v2 0/2] qemu: Ignore RESET/SHUTDOWN events during startup
by Peter Krempa 30 Jul '21

30 Jul '21

Before we resume the CPUs there was no guest code executed so the events emitted by qemu are purely based on libvirt actions. Ignore them since they are emitted when we are resetting the machine so that it picks up hotplugged disks.

[libvirt PATCH] gitlab: use custom docker:dind image
by Daniel P. Berrangé 30 Jul '21

30 Jul '21

The current docker:dind container has broken default seccomp filter that results in clone3 being blocked, which in turn breaks Fedora 35 rawhide. This custom image has a workaround that causes the seccomp filter to return ENOSYS for clone3 instad of EPERM, thus triggering glibc to fallback to clone correctly. Signed-off-by: Daniel P.

Entering freeze for libvirt-7.6.0
by Pavel Hrdina 30 Jul '21

30 Jul '21

I have just tagged v7.6.0-rc1 in the repository and pushed signed tarballs and source RPMs to https://libvirt.org/sources/ Please give the release candidate some testing and in case you find a serious issue which should have a fix in the upcoming release, feel free to reply to this thread to make sure the issue is more visible. If you have not done so yet, please update NEWS.rst to document any significant change you made since the last release. Thanks, Pavel

[libvirt][PATCH v4 0/4] Support query and use SGX
by Haibin Huang 28 Jul '21

28 Jul '21

This patch series provides support for enabling Intel's Software Guard Extensions (SGX) feature in guest VM. Giving the SGX support in QEMU is still pending for reviewing, this patch series is not submmited for code review, but only describe the SGX enabling solution design that contains changes to virConnectGetDomainCapabilities API response and domain definition. All comments/suggestions would be highly appreciated. Intel Software Guard Extensions (Intel® SGX) is a set of instructions that increases the security of application code and data, giving them more protection from disclosure or modification. Developers can partition sensitive information into enclaves, which are areas of execution in memory with more security protection. The typical flow looks below at very high level: 1. Calls virConnectGetDomainCapabilities API to domain capabilities that includes the following SGX information. <feature> ... <sgx supported='yes'> <epc_size unit=’KiB’>N</epc_size> </sgx> </feature> 2. User requests to start a guest calling virCreateXML() with SGX requirement. It should contain <launchSecurity type='sgx'> <epc_size unit='KiB'>N</epc_size> </launchSecurity> Haibin Huang (1): Support to query SGX capability Lin Yang (3): conf: Introduce SGX related element

Turning off -Werror

commit 3c3c55be66e230ef09ad927eda038dc32f01a166 Author: Daniel P. Berrangé <berrange(a)redhat.com> Date: Thu Apr 8 11:50:30 2021 +0100 meson: don't probe for -Werror if --werror is enabled Builds are failing in Fedora Rawhide at the moment because of a warning being turned into an error. Fedora's spec file has this which is supposed to turn off -Werror, but it no longer works after the above commit was added. https://src.fedoraproject.org/rpms/libvirt/blob/rawhide/f/libvirt.spec#_189 I'm trying to understand how you're supposed to turn off -Werror. According to meson documentation omitting --werror should work. According to some different docs, use --werror=false. Neither are working for me. I'm actually wondering if the commit above is wrong.
