[libvirt] [PATCH 0/9] Resolve libvirtd hang on termination with connected long running client
by John Ferlan
RFC:
https://www.redhat.com/archives/libvir-list/2018-January/msg00318.html
Adjustments since RFC...
Patches 1&2: No change, were already R-B'd
Patch 3: Removed code as noted in code review, update commit message
Patch 4: From old series removed, see below for more details
Patch 9: no change
NB: Patches 5-8 and 10 from Nikolay Shirokovskiy <nshirokovskiy(a)virtuozzo.com>
are removed as they seemed to not be necessary
Replaced the former patch 4 with series of patches to (slowly) provide
support to disable new connections, handle removing waiting jobs, causing
the waiting workers to quit, and allow any running jobs to complete.
As it turns out, waiting for running jobs to complete cannot be done
from the virNetServerClose callbacks because that means the event loop
processing done during virNetServerRun will not allow any currently
long running worker job thread a means to complete.
So when virNetDaemonQuit is called as a result of the libvirtd signal
handlers for SIG{QUIT|INT|TERM}, instead of just causing virNetServerRun
to quit immediately, alter to using a quitRequested flag and then use
that quitRequested flag to check for long running worker threads before
causing the event loop to quit resulting in libvirtd being able to run
through the virNetDaemonClose processing.
John Ferlan (9):
libvirtd: Alter refcnt processing for domain server objects
libvirtd: Alter refcnt processing for server program objects
netserver: Remove ServiceToggle during ServerDispose
util: Introduce virThreadPoolDrain
rpc: Introduce virNetServerQuitRequested
rpc: Introduce virNetServerWorkerCount
rpc: Alter virNetDaemonQuit processing

[libvirt] Call to virDomainIsActive hangs forever
by Mathieu Tarral
Hi !
I'm submitting my messages on this mailing list to request a bit of
help on a case that I have
where a Python application makes a call to virDomainIsActive, and the
call never returns.
I have tried to investigate, but as there are no debug symbols for
libvirt on Debian Stretch,
i can only have the following GDB backtrace:
(gdb) bt
#0 pthread_cond_wait@(a)GLIBC_2.3.2 () at
../sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185
#1 0x00007f49026f5b76 in virCondWait () from /usr/lib/libvirt.so.0
#2 0x00007f4902808bab in ?? () from /usr/lib/libvirt.so.0

#4 0x00007f490280abe2 in virNetClientProgramCall () from /usr/lib/libvirt.so.0
#5 0x00007f49027e0ea4 in ?? () from /usr/lib/libvirt.so.0
#6 0x00007f49027ea1bb in ?? () from /usr/lib/libvirt.so.0
#7 0x00007f49027b0ef3 in virDomainIsActive () from /usr/lib/libvirt.so.0
#8 0x00007f4902b7fbd0 in libvirt_virDomainIsActive () from
/usr/lib/python3/dist-packages/libvirtmod.cpython-35m-x86_64-linux-gnu.so
#9 0x0000558eeec696df in PyCFunction_Call () at ../Objects/methodobject.c:109
The libvirt driver used is QEMU, and i have a specific monitoring in
place using virtual machine introspection:
https://github.com/KVM-VMI/kvm-vmi
Now this specific monitoring somehow triggers this bug, and at this
point, i don't know if
it's a corner case in the libvirt QEMU driver or not.
That's why i would like to have your lights on this.
libvirt version: 3.0.0-4
-> Could you tell me where i should look in the code ?
-> Do you have more information about this virCondWait ? Which
condition is it waiting for ?
-> How can i get the symbols without having the recompile libvirt and
install it system wide, erasing the binaries installed by the package
?
Best regards,

[libvirt] [PATCH 00/12] Various apparmor related changes (part )
by Christian Ehrhardt
Hi,
this is a continuation of the ongoing effort to feed back Ubuntu apparmor
Delta on libvirt to the community (or to sort out remaining todos or to keep
them distro specific).
In that it is a follow on to:
- https://www.redhat.com/archives/libvir-list/2017-May/msg00630.html
- https://www.redhat.com/archives/libvir-list/2017-May/msg00887.html
I punted those we had discussions on and decided to rework in the last rounds
out of the submission.
But in exchange pulled in some more changes we had that are now ready for
discussion. That way I prepared the next set of 12 changes which I hereby
submit for your consideration into 3.11.
Christian Ehrhardt (3):
apparmor, libvirt-qemu: add default pki path of lbvirt-spice
apparmor, libvirt-qemu: add generic base vfio device
apparmor, libvirt-qemu: qemu won't call qemu-nbd
Jamie Strandboge (5):
apparmor, libvirt-qemu: Allow read access to sysfs system info
apparmor, libvirt-qemu: Allow qemu-block-extra libraries
apparmor, libvirtd: Allow ixr to /var/lib/libvirt/virtd*
apparmor, virt-aa-helper: Allow access to ecryptfs files
apparmor, virt-aa-helper: Allow access to /sys/bus/usb/devices
Serge Hallyn (3):
apparmor, libvirt-qemu: Allow use of sgabios
apparmor, libvirt-qemu: Allow read access to max_mem_regions
apparmor, libvirt-qemu: Allow access to hugepage mounts
Stefan Bader (1):
apparmor, libvirt-qemu: Silence lttng related deny messages

[libvirt] [PATCH] qemu: Honour <on_reboot/>
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1476866
For some reason, we completely ignore <on_reboot/> setting for
domains. The implementation is simply not there. It never was.
However, things are slightly more complicated. QEMU sends us two
RESET events on domain reboot. Fortunately, the event contains
this 'guest' field telling us who initiated the reboot. And since
we don't want to destroy the domain if the reset is initiated by
a user, we have to ignore those events. Whatever, just look at
the code.

[libvirt] [PATCH] bhyve: add support for passing stdin to loader
by Fabian Freyer
This commit adds the <bootloader_stdin> node to the domain definition,
with the following semantics:
To pass standard input verbatim to the bootloader, set
<bootloader_stdin>some stdin</bootloader_stdin>
Multiline standard input can be set using a CDATA tag:
<bootloader_stdin><![CDATA[
this standard input
will be passed in with
newlines and indentation.
]]></bootloader_stdin>
Standard input can be read from a file as follows:
<bootloader_stdin file="/path/to/some/file"/>

[libvirt] [GSoC] Design ideas for implementing cleanup attribute
by Sukrit Bhatnagar
Hi,
I am interested in implementing the GCC cleanup attribute for automatic
resource freeing as part of GSoC'18. I have shared a proposal for the same.
This mail is to discuss the code design for implementing it.
Here are some of my ideas:
This attribute requires a cleanup function that is called automatically
when the corresponding variable goes out of scope. There are some functions
whose logic can be reused:
- Functions such as virCommandFree, virConfFreeList and virCgroupFree can
be directly used as cleanup functions. They have parameter and return type
valid for a cleanup function.
- Functions such as virFileClose and virFileFclose need some additional
consideration as they return a value. I think we can set some global
variable in a separate source file (just like errno variable from errno.h).
Then the value to be returned can be accessed globally.
- Functions such as virDomainEventGraphicsDispose need an entirely new
design. They are used as callbacks in object classes and passed as an
argument in virClassNew. This would require making changes to
virObjectUnref's code too. *This is the part I am not sure how to implement
cleanup logic for.*
Also, since the __attribute__((__cleanup__(anyfunc))) looks ugly, a macro
like autoclean (ideas for macro name welcome!) can be used instead. As
Martin pointed out in my proposal, for some types, this can be done right
after typedef declarations, so that the type itself contains this attribute.
Basically, at most places where VIR_FREE is used to release memory
explicitly, the corresponding variable can use the attribute. The existing
virFree function also can be reused as it takes void pointer as an argument
and returns nothing.
One of the exceptions to this will be those variables which are struct
members. The cleanup of member has to be done when the enclosing struct
variable is cleaned.
I can create new files vircleanup.{c,h} for defining cleanup functions for
types which do not have an existing cleanup/free function. This can be done
separately for each driver supported.
For example, cleanups pertaining to lxc driver will be in
src/lxc/lxc_cleanup.c.
Your suggestions are welcome.
Thanks,
Sukrit Bhatnagar

[libvirt] [RFC 0/3] LXC with block device and enabled userns
by Radostin Stoyanov
Problem background
------------------
The LXC driver has support for the filesystem types "file" and "block"
that allow a disk image to be mounted in the guest (container). [1]
However, when user-namespace is enabled (uid/gid mapping is used) the
mount of the root filesystem block device fails. [2]
According to "man 7 user_namespaces":
Mounting block-based filesystems can be done only by a process that holds
CAP_SYS_ADMIN in the initial user namespace.
Suggested approach
------------------
Mount the root file system block device before the clone() call, then set
filesystem type to VIR_DOMAIN_FS_TYPE_MOUNT and filesystem source to the folder
where it was mounted.
Issues encountered
--------------------
This patch series implements the basic idea of the mentioned approach.
In result, a container with configured idmap and NBD filesystem is able to start.
However, on guest shutdown this kernel error [3] occurs.
Similar messages [4] occur on shutdown when NBD filesystem is used with LXC
container without idmap.
Perhaps, one reason could be that on guest shutdown the LXC driver kills qemu-nbd
process without sending disconnect for the specified device.
