[libvirt] [PATCH 0/9] extend virsh domstate to show additional information
by Bjoern Walk 16 Jul '18

16 Jul '18

This patch series introduces the ability to save additional information for the domain state and exposes this information in virsh domstate. For example in the case of QEMU guest panic events, we can provide additional information like the crash reason or register state of the domain. This information usually gets logged in the domain log but for debugging it is useful to have it accessible from the client. Therefore, let's introduce a new public API function, virDomainGetStateParams, an extensible version of virDomainGetState, which returns the complete state of the domain, including newly introduced additional information. Let's also extend virsh domstate and introduce a new parameter --info to show the domain state, reason and additional information when available. virsh # domstate --info guest-1 crashed (panicked: disabled-wait core='1' psw-mask='0x000000000010f146' \ psw-addr='0x0002000180000000') Bjoern Walk (9): conf: add info to virDomainStateReason conf: set/retrieve state information lib: introduce virDomainGetStateParams function remote: implement remoteDomainGetStateParams qemu: implement qemuDomainGetStateParams qemu: set state information for guest panic event virsh: domstate: report detailed state if available news: add entry for virDomainGetStateParams qemu: fix order of S390 panic event information docs/news.xml | 11 ++++++ include/libvirt/libvirt-domain.h | 24 ++++++++++++ src/conf/domain_conf.c | 16 +++++++- src/conf/domain_conf.h | 7 ++++ src/driver-hypervisor.h | 7 ++++ src/libvirt-domain.c | 56 ++++++++++++++++++++++++++ src/libvirt_private.syms | 1 + src/libvirt_public.syms | 5 +++ src/qemu/qemu_driver.c | 61 ++++++++++++++++++++++++++++- src/qemu/qemu_monitor.c | 39 ++++++++++++++++-- src/qemu/qemu_monitor.h | 1 + src/remote/remote_daemon_dispatch.c | 1 - src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 20 +++++++++- src/remote_protocol-structs | 11 ++++++ tools/virsh-domain-monitor.c | 31 ++++++++++++--- tools/virsh.pod | 5 ++- 17 files changed, 281 insertions(+), 16 deletions(-) -- 2.17.0

[libvirt] [PATCH v2] qemu: fix broken autostart symlink after renaming domain.
by Julio Faracco 16 Jul '18

16 Jul '18

If a domain is configured to start on boot, it has a symlink to the domain definition inside the autostart directory. If you rename this domain, the definition is renamed too. The symlink need to be pointed to this renamed file. This commit recreates the symlink after renaming the XML file.
