[libvirt] Release of libvirt-4.10.0
by Daniel Veillard 03 Dec '18

03 Dec '18

As planned I tagged the release in git earlier today and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ I also pushed the python bindings at ftp://libvirt.org/libvirt/python This release seems to be very heavy on new features, but under the hood there is as usuall a number of bug fixes and refactoring patches: New features: - qemu: Add Hyper-V PV IPI and Enlightened VMCS support The QEMU driver now has support for Hyper-V PV IPI and Enlightened VMCS for Windows and Hyper-V guests. - qemu: Added support for PCI devices on S390 PCI addresses can now include the new zpci element which contains uid (user-defined identifier) and fid (PCI function identifier) attributes and makes the corresponding devices usable by S390 guests. - Support changing IOThread polling parameters for a live guest Introduced virDomainSetIOThreadParams which allows dynamically setting the IOThread polling parameters used by QEMU to manage the thread polling interval and the algorithm for growth or shrink of the polling time. The values only affect a running guest with IOThreads. The guest's IOThread polling values can be viewed via the domain statistics. - Xen: Add support for PVH The libxl driver now supports Xen's PVH virtual machine type. PVH machines are enabled with the new "xenpvh" OS type, e.g. <os><type>xenpvh</type></os> - qemu: Added support for CMT (Cache Monitoring Technology) Introduced cache monitoring using the monitor element in cachetune for vCPU threads. Added interfaces to get and display the cache utilization statistics through the command 'virsh domstats' via the virConnectGetAllDomainStats API. - qemu: Add support for nested HV for pSeries guests Nested HV support makes it possible to run nested (L2) guests with minimal performance penalty when compared to regular (L1) guests on ppc64 hardware. Bug fixes: - Xen: Handle soft reset shutdown event The pvops Linux kernel uses soft reset to handle the crash machine operation. The libxl driver now supports the soft reset shutdown event, allowing proper crash handling of pvops-based HVM domains. Thanks everybody for your contribution toward this release, be it with ideas, bug reports, patches reviews, docs, localization... Remember, next release should be around mid-January, 5.0.0, in the meantime enjoy the release and end of years vacations you may have !

[libvirt] [PATCH 0/7] Restructure firewall rules for virtual networks into private chains
by Daniel P. Berrangé 03 Dec '18

03 Dec '18

The virtual networks in NAT mode are supposed to only allow outbound network access for guests. Unfortunately due to ordering of the firewall rules libvirt creates, when you have multiple virtual networks, guests on the more recently created virtual networks can connect to guests on old virtual networks. This was reported way back in 2008 but we always thought the fix would be very complicated to deal with, so we've been putting it off forever. In parallel with this there's also been a long standing desire since 2009 to move our firewall rules out of the builtin chains, to libvirt private chains. This is to make it easier for admins to use hook scripts to setup rules in the builtin chains that take priority over rules libvirt creates. In implementing the changes to use private chains, I suddenly realized that fixing the network to network traffic blocking problem was trivial if I grouped the forwarding rules into three distinct sets. So this series finally fixes an annoying 10 year old bug, and implements a 9 year old RFE. It may take us a while, but we'll get to your bugs eventually ;-) Daniel P. Berrangé (7): util: refactor iptables APIs to share more code util: add iptables API for creating base chains util: prepare iptables for putting rules into private chains network: setup default iptables chains util: switch over to creating rules in private chains tests: remove duplicated test case in networkxml2firewalltest tests: fix dry run handling in network firewall test src/libvirt_private.syms | 1 + src/network/bridge_driver_linux.c | 3 + src/util/viriptables.c | 317 ++++++++++++++---- src/util/viriptables.h | 2 + .../nat-default-linux.args | 150 ++++++++- .../nat-ipv6-linux.args | 166 +++++++-- .../nat-many-ips-linux.args | 178 ++++++++-- .../nat-no-dhcp-linux.args | 164 +++++++-- .../nat-tftp-linux.args | 152 ++++++++- .../route-default-linux.args | 140 +++++++- tests/networkxml2firewalltest.c | 17 +- 11 files changed, 1107 insertions(+), 183 deletions(-) -- 2.19.1

[libvirt] [PATCH v3 00/11] Autoselect a DRM node for egl-headless add it to cmdline
by Erik Skultety 03 Dec '18

03 Dec '18

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1628892. The problem is that we didn't put the DRI device into the namespace for QEMU to access, but that was only a part of the issue. The other part of the issue is that QEMU doesn't support specifying 'rendernode' for egl-headless yet (patches are already in upstream) Instead, QEMU's been autoselecting the DRI device on its own. There's no compelling reason for libvirt not doing that instead and thus prevent any permission-related issues. Since v1: - updated capabilities to 3.1.0-rc2 containing the necessary QEMU patches - provided more test cases as requested - added a new XML sub-element <gl> for egl-headless graphics type Since v2: - The cmdline code wouldn't play nicely with old QEMU where I'd pick a rendernode automatically and then fail if we didn't have the corresponding capability, so this was fixed for v3 - v2 converted some tests to CAPS_LATEST only which would also be wrong because QEMU can still pick a DRM node so that's a valid use case (not a practical one though) - the 3.1.0 capabilities patch was merged separately Erik Skultety (11): util: Introduce virHostGetDRMRenderNode helper conf: Introduce virDomainGraphics-related helpers qemu: process: spice: Pick the first available DRM render node qemu: command: Introduce qemuBuildGraphicsEGLHeadlessCommandLine helper qemu: caps: Introduce QEMU_EGL_HEADLESS_RENDERNODE capability conf: gfx: Add egl-headless as a member to virDomainGraphicsDef struct conf: gfx: egl-headless: Introduce a new <gl> subelement qemu: domain: egl-headless: Add the DRI device into the namespace qemu: cgroup: gfx: egl-headless: Add the DRI device into the cgroup list security: dac: gfx: egl-headless: Relabel the DRI device qemu: command: gfx: egl-headless: Add 'rendernode' option to the cmdline docs/formatdomain.html.in | 11 ++- docs/schemas/domaincommon.rng | 17 +++- src/conf/domain_conf.c | 84 +++++++++++++++++++ src/conf/domain_conf.h | 12 +++ src/libvirt_private.syms | 4 + src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_cgroup.c | 10 +-- src/qemu/qemu_command.c | 42 +++++++++- src/qemu/qemu_domain.c | 9 +- src/qemu/qemu_process.c | 32 ++++++- src/security/security_dac.c | 15 ++-- src/util/virutil.c | 53 ++++++++++++ src/util/virutil.h | 2 + .../caps_3.1.0.x86_64.xml | 1 + ...egl-headless-rendernode.x86_64-latest.args | 31 +++++++ .../graphics-egl-headless-rendernode.xml | 33 ++++++++ .../graphics-egl-headless.x86_64-latest.args | 31 +++++++ .../graphics-spice-gl-no-rendernode.args | 25 ++++++ .../graphics-spice-gl-no-rendernode.xml | 24 ++++++ ...play-spice-egl-headless.x86_64-latest.args | 2 +- ...isplay-vnc-egl-headless.x86_64-latest.args | 2 +- tests/qemuxml2argvmock.c | 9 ++ tests/qemuxml2argvtest.c | 2 + .../graphics-egl-headless-rendernode.xml | 41 +++++++++ tests/qemuxml2xmltest.c | 2 + 26 files changed, 464 insertions(+), 33 deletions(-) create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless-rendernode.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless-rendernode.xml create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless.x86_64-latest.args create mode 100644 tests/qemuxml2argvdata/graphics-spice-gl-no-rendernode.args create mode 100644 tests/qemuxml2argvdata/graphics-spice-gl-no-rendernode.xml create mode 100644 tests/qemuxml2xmloutdata/graphics-egl-headless-rendernode.xml -- 2.19.1

[libvirt] [PATCH v2] qemu: handle multicast overflow on macvtap NIC_RX_FILTER_CHANGED
by Jason Baron 03 Dec '18

03 Dec '18

Guest network devices can set 'overflow' when there are a number of multicast ips configured. For virtio_net, the limit is only 64. In this case, the list of mac addresses is empty and the 'overflow' condition is set. Thus, the guest will currently receive no multicast traffic in this state. When 'overflow' is set in the guest, let's turn this into ALLMULTI on the host.
