[libvirt] [PATCH] remote_daemon: Log host boot time
by Michal Privoznik
This is not strictly needed, but it makes sure we initialize the
@bootTime global variable. Thing is, in order to validate XATTRs
and prune those set in some previous runs of the host, a
timestamp is recorded in XATTRs. The host boot time was unique
enough so it was chosen as the timestamp value. And to avoid
querying and parsing /proc/uptime every time, the query function
does that only once and stores the boot time in a global
variable. However, the only time the query function is called is
in a child process that does lock files and changes seclabels. So
effectively, we are doing exactly what we wanted to prevent from
happening.
The fix is simple, call the query function whilst the daemon is
initializing.

Since this will be used by security driver only, I was tempted to put
this somewhere under src/security/, but especially because of split
daemon I didn't. Placing this into remote_daemon.c makes sure all
sub-daemons will have the variable initialized and won't suffer the
problem.

[libvirt] [PATCH 1/1] qemu: hide details of fake reboot
by Nikolay Shirokovskiy
If we use fake reboot then domain goes thru running->shutdown->running
state changes with shutdown state only for short period of time. At
least this is implementation details leaking into API. And also there is
one real case when this is not convinient. I'm doing a backup with the
help of temporary block snapshot (with the help of qemu's API which is
used in the newly created libvirt's backup API). If guest is shutdowned
I want to continue to backup so I don't kill the process and domain is
in shutdown state. Later when backup is finished I want to destroy qemu
process. So I check if it is in shutdowned state and destroy it if it
is. Now if instead of shutdown domain got fake reboot then I can destroy
process in the middle of fake reboot process.
After shutdown event we also get stop event and now as domain state is
running it will be transitioned to paused state and back to running
later. Though this is not critical for the described case I guess it is
better not to leak these details to user too. So let's leave domain in
running state on stop event if fake reboot is in process.
As we don't know when stop event really arrive let's move resetting flag
after starting CPUs - at this point stop event should be handled.

[libvirt] [PATCH v2 0/4] move qemucaps validations from qemu_command to qemu_domain
by Daniel Henrique Barboza
Most of the patches were pushed in the first version. These
are the patches that didn't make the cut and needed new
versions.
After these patches I'll refrain from doing more validation
moves to qemu_domain.c. I'll send a RFC discussing how we can
move all the validations to a new file first, then we can
resume this work in the definitive location instead.
Changes from previous version 1 [1]:
- patch 1 (former patch 04): moved the validation to a new
qemuDomainDeviceDefValidateMemory() function which is called by
qemuDomainDeviceDefValidate().
- patch 2 (former patch 23): added the missing
"if (graphics->data.egl_headless.rendernode)" check.
- patch 3 (former patch 24): virReportEnumRangeError is now being
used in the "default" label error case.
- patch 4 (new): added the VMCOREINFO validation case that I
mentioned about in the cover letter of [1] as a difficult
case, but Cole mentioned that it was simpler than that and that I
was probably missing something. Cole was right.
