[libvirt] [PATCH] tools: console: Relax stream EOF handling
by Roman Bolshakov 27 Aug '19

An attempt to poweroff a VM from inside triggers the error for existing session of virsh console and it returns with non-zero exit code: error: internal error: console stream EOF The message and status code are misleading because there's no real error.

[libvirt] [RFC PATCH 0/2] qemu: Enable -blockdev [READ ME!] (blockdev-add saga finale?)
by Peter Krempa 26 Aug '19

26 Aug '19

With the patches I've posted to the list libvirt should be mostly prepared to use -blockdev instead of -drive to specify disk images. There's one gothcha though. Internal snapshots don't work due to qemu considering every monitor-owned node for snapshot as well. With blockdev everything became monitor-owned including the 'file' nodes which are definitely not snapshottable. Even when qemu fixes that bug I don't think it will be introspectable. Our options are either to wait for the qemu fix and then try to detect it somehow, perhaps as a version check (yuck), or go ahead and inform users to upgrade to a newer qemu afterwards. Any other ideas or suggestions?

[libvirt] [PATCH 0/6] Honour use of /run instead of /var/run on distros
by Daniel P. Berrangé 26 Aug '19

26 Aug '19

Distros using systemd all use /run instead of /var/run. Libvirt has not adapted, relying on the symlink between the two for compat. This is an issue for UNIX sockets though, as systemd rewrites /var/run to /run before binding to a socket and this means libvirtd cannot identify sockets it is passed with old systemd. Daniel P. Berrangé (6): build: use $(COMMON_UNIT_VARS) for logging/locking systemd units systemd: honour $runstatedir in socket unit files build: honour $(runstatedir) in make rules src: honour the RUNSTATEDIR variable in all code build: support customization of runstatedir variable with old autoconf rpm: set runstatedir to /run directory configure.ac | 23 +++++++++++++++++ libvirt.spec.in | 15 +++++------ src/Makefile.am | 2 +- src/bhyve/bhyve_utils.h | 2 +- src/interface/interface_backend_netcf.c | 2 +- src/interface/interface_backend_udev.c | 2 +- src/libvirt-admin.c | 2 +- src/libxl/Makefile.inc.am | 4 +-- src/libxl/libxl_conf.h | 2 +- src/locking/Makefile.inc.am | 20 ++++----------- src/locking/lock_daemon.c | 18 +++++++------- src/locking/lock_driver_lockd.c | 2 +- src/locking/virtlockd-admin.socket.in | 2 +- src/locking/virtlockd.pod | 8 +++--- src/locking/virtlockd.socket.in | 2 +- src/logging/Makefile.inc.am | 16 +++--------- src/logging/log_daemon.c | 18 +++++++------- src/logging/log_manager.c | 2 +- src/logging/virtlogd-admin.socket.in | 2 +- src/logging/virtlogd.pod | 8 +++--- src/logging/virtlogd.socket.in | 2 +- src/lxc/Makefile.inc.am | 4 +-- src/lxc/lxc_conf.h | 2 +- src/lxc/lxc_process.c | 2 +- src/network/Makefile.inc.am | 4 +-- src/network/bridge_driver.c | 4 +-- src/network/leaseshelper.c | 2 +- src/node_device/node_device_hal.c | 2 +- src/node_device/node_device_udev.c | 2 +- src/nwfilter/nwfilter_dhcpsnoop.c | 4 +-- src/nwfilter/nwfilter_driver.c | 4 +-- src/qemu/Makefile.inc.am | 8 +++--- src/qemu/qemu_conf.c | 4 +-- src/remote/Makefile.inc.am | 4 +++ src/remote/libvirtd-admin.socket.in | 2 +- src/remote/libvirtd-ro.socket.in | 2 +- src/remote/libvirtd.conf.in | 2 +- src/remote/libvirtd.pod | 10 ++++---- src/remote/libvirtd.socket.in | 2 +- src/remote/remote_daemon.c | 24 +++++++++--------- src/remote/remote_daemon_dispatch.c | 4 +-- src/remote/remote_driver.c | 6 +++++ src/remote/test_libvirtd.aug.in | 2 +- src/secret/secret_driver.c | 2 +- src/security/virt-aa-helper.c | 20 ++++++--------- src/storage/storage_driver.c | 2 +- src/util/virhostdev.c | 2 +- src/util/virpidfile.c | 8 +++--- src/util/virsystemd.c | 33 ++++++++++++++++--------- src/vz/vz_driver.c | 2 +- 50 files changed, 172 insertions(+), 151 deletions(-) -- 2.21.0

[libvirt] [PATCH] qemu: Use the same def when attaching device live and config
by wujing (O) 26 Aug '19

26 Aug '19

Patch 55ce6564634 caused a problem fixed in 1e0534a7702, described as below: Some members are generated during XML parse (e.g. MAC address of an interface); However, with current implementation, if we are plugging a device both to persistent and live config, we parse given XML twice: first time for live, second for config. This is wrong then as the second time we are not guaranteed to generate same values as we did for the first time. To solve that, we should use the same def when attaching a device config and live. And leave the current process unchanged when using --config and --live separately.
