[libvirt] [PATCH] qemuProcessHandleMonitorEOF: Disable namespace for domain
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1430634
If a qemu process has died, we get EOF on its monitor. At this
point, since qemu process was the only one running in the
namespace kernel has already cleaned the namespace up. Any
attempt of ours to enter it has to fail.
This really happened in the bug linked above. We've tried to
attach a disk to qemu and while we were in the monitor talking to
qemu it just died. Therefore our code tried to do some roll back
(e.g. deny the device in cgroups again, restore labels, etc.).
However, during the roll back (esp. when restoring labels) we
still thought that domain has a namespace. So we used secdriver's
transactions. This failed as there is no namespace to enter.

[libvirt] [PATCH] qemuxml2argvtest: Don't overwrite driver stateDir
by Michal Privoznik
This is a very historic artefact. Back in the old days of
830ba76c3e when we had macros to add arguments onto qemu command
line (!) we thought it was a good idea to let qemu write out the
PID file. So we passed -pidfile $stateDir/$domName onto the
command line. Thus, in order for tests to work we needed stable
stateDir in the qemu driver. Unfortunately, after 16efa11aa696
where stateDir is mkdtemp()-d, this approach lead to a leak of
temp dir.

[libvirt] [PATCH v2] Revert "conf: move iothread XML validation from qemu_command"
by Pavel Hrdina
This reverts commit c96bd78e4e71c799dc391566fa9f0652dec55dca.
So our code is one big mess and we modify domain definition while
building qemu_command line and our hotplug code share only part
of the parsing and command line building code. Let's revert
that change because to fix it properly would require refactor and
move a lot of things.

[libvirt] Revisiting qemu monitor timeout on VM start
by Jim Fehlig
Hi All,
Encountering a qemu monitor timeout when starting a VM has been discussed here
before, e.g.
https://www.redhat.com/archives/libvir-list/2014-January/msg00060.html
https://www.redhat.com/archives/libvir-list/2014-January/msg00408.html
Recently I've received reports of the same when starting large memory VMs backed
by 1G huge pages. In one of the reports, Matt timed how long it takes to
allocate 402GB worth of hugetlbfs pages (these are 1G pages, but the time is
similar for 2M):
real 105.47
user 0.05
sys 105.42
The time is spent entirely in the kernel zero'ing pages and as you can see it
exceeds the 30 second monitor timeout in libvirt. Do folks have any suggestions
on how to avoid the timeout?
Obviously one solution is to introduce a knob in qemu.conf to control the
timeout, as was proposed in the above threads. Another solution that came to
mind is changing qemu to open the monitor earlier, making it available while the
kernel is off scrubbing pages. I'm not familiar enough with qemu code to know if
such a change is possible, but given the amount of initialization done in main()
prior to calling mon_init_func(), my confidence in this idea is low. Perhaps
someone more familiar with qemu initialization can comment on that. Thanks in
advance for comments on these ideas or alternate proposals!
Regards,
Jim

[libvirt] [PATCH] domain_conf: move iothread check for address type back to qemu_command
by Pavel Hrdina
This partially reverts commit c96bd78e4e.
If an API virDomainAttachDevice(Flags) is used the device address
is assigned after the validation and the address type may not be set.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1430275

[libvirt] [PATCH] doc updates
by Philipp Hahn
Hi,
here are 3 patches to improve the documentation:
the 1st one is a re-sent from 2013,
the 2nd one is my version of a patch proposed 2011,
the 3rd is probably most controversal, so drop it if you don't like it. The
QEMU homepage spellts it "QEMU" and "qemu" is used a lot for the binary, but
"Qemu" is used very little.
Philipp Hahn (3):
doc: add storage format entries
doc: Correct the default werror policy
doc: fix writing of QEMU
