[libvirt] [PATCH] virDirRead: Fix d_type if needed
by Michal Privoznik
Some of our code iterates over a directory and does some
decisions based on entry type (e.g. if it's not a regular file
continue with next iteration). This is done by looking at
ent->d_type struct member. However, in some cases (e.g. for some
filesystems) the d_type can be set to DT_UNKNOWN which
effectively defeats the aforementioned checks. For instance, some
XFS' (depending on how they were created) might not bother
filling the member.
Fix this by running stat() and filling in the member ourselves.
If needed.

With Dan's patch that fixes stat() mocking, I'm passing tests
successfully everywhere I tried (32bit fedora and gentoo on RPi, RHEL-7,
amd64 gentoo, fedora rawhide on x86_64)

[libvirt] [PATCH v2] examples: fix 64-bit integer formatting on Windows
by Daniel P. Berrangé
The Windows printf functions don't support %llu/%lld for printing 64-bit
integers. For most of libvirt this doesn't matter as we rely on gnulib
which provides a replacement printf that is sane.
The example code is designed to compile against the normal OS headers,
with no use of gnulib and thus has to use the platform specific printf.
To deal with this we must use the macros PRI* macros from inttypes.h
to get the platform specific format string.

[libvirt] [PATCH 0/3] introducing QEMU_CAPS_QUERY_CURRENT_MACHINE and QEMU_CAPS_WAKEUP_SUSPEND_SUPPORT
by Daniel Henrique Barboza
Hi,
In this series, I present the Libvirt support for a QEMU API that
will be introduced in QEMU 4.0, called 'query-current-machine'.
More background info about the API and its purpose can be found in
the commit msg of patch 1.
Patch 1 contains the caps declarations (a short patch, perhaps
squashable with patch 2).
Patch 2 enable the QEMU_CAPS_WAKEUP_SUSPEND_SUPPORT cap by querying
'query-current-machine', if the QEMU binary supports it.
Patch 3 uses the caps inside qemuDomainPMSuspendForDuration to avoid
suspending a domain that can't wake up from suspend.
Daniel Henrique Barboza (3):
adding QEMU_CAPS_QUERY_CURRENT_MACHINE and
QEMU_CAPS_WAKEUP_SUSPEND_SUPPORT
setting QEMU_CAPS_WAKEUP_SUSPEND_SUPPORT qemu capability
qemuDomainPMSuspendForDuration: check for
QEMU_CAPS_WAKEUP_SUSPEND_SUPPORT

[libvirt] Can jobs suck like qemu-pr-helper does be transfered to libvirtd?
by Zhangbo (Oscar)
Hi all:
qemu-pr-helper exits to help qemu do the high-privileged scsi related jobs. LIBVIRTD is responsible to launch qemu-pr-helper and qemu, and set selinux/DAC labels for them and their socket.
#
#
#
#
# ___________
# ___________|libvirtd |__________
# | |___________| |
# | | |
# | | |
# _________|________ _____|______ ___|____
# | qemu-pr-helper |__| vm1.sock |_____| qemu1 |
# |__________________| |____________| |________|
There may be other jobs quite like qemu-pr-helper, shall we make them as "complex" as the qemu-pr-helper scheme?
Will it be OK to just let qemu send an EVENT to libvirtd, and let libvirtd do the SCSI/other jobs? Will it be OK if we remove qemu-pr-helper and similar processes?
What's the disadvantage if we let libvirtd do there high privileged jobs instead qemu-pr-helper-like processes?
Thanks!

[libvirt] vcpupin reports bogus vcpu affinities
by Allen, John
Sent this out to the list a few days ago, but never saw it appear on the
archives. Resending--hopefully this makes it to the list.
---
For pinned vcpus, vcpupin will report inaccurate affinity values on machines
with high core counts (256 cores in my case). The problem is produced as
follows:
$ virsh vcpupin myguest 0 4
$ virsh vcpupin myguest 0
VCPU CPU Affinity
---------------------------
0 4,192,194,196-197
Running taskset on the qemu threads shows the correct affinity, so this seems
to be a reporting problem. Strangely, the value "192" is significant. If I pin
a cpu greater than 192, the problem no longer appears.
I believe the cause of the problem in my case is that in this case in
src/conf/domain_conf.c:virDomainDefGetVcpuPinInfoHelper:
...
if (vcpu && vcpu->cpumask)
bitmap = vcpu->cpumask;
...
vcpu->cpumask is "shortened" in that it is only long enough to contain the last
set bit in the mask. However, when we go to copy the mask to the buffer that is
returned, we use the masklen passed to the function which is the "full"
masklen with a bit for each cpu. So it seems virBitmapToDataBuf copies some
extra data past the end of the bitmask. Why the "192" value is always set and I
typically see similar bogus bits set is still unknown.
What is the function meant to assume in this case? Is it sane to assume that
the bitmask is the full length of the buffer here and it's the responsibility
of the setter of vcpu->cpumask to provide the length of the bitmap we're
expecting? Or should we assume that we may receive a shortened bitmask here and
expand the bitmask before copying to the buffer?

[libvirt] [PATCH] virerror: Make error reporting prettier
by Michal Privoznik
So far, if something goes wrong we print an error message, e.g.
like this:
virsh # start fedora
error: Failed to start domain fedora
error: internal error: process exited while connecting to monitor: 2019-04-01T08:08:49.753850Z qemu-system-x86_64: -object memory-backend-memfd,id=ram-node0,hugetlb=yes,hugetlbsize=0,size=8589934592,host-nodes=0,policy=bind: Property 'memory-backend-memfd.hugetlbsize' doesn't take value '0'
This is very boring and usually too low level for users to know
what is going on or how to fix the problem. Let's reimplement our
error reporting then. After this patch the previous error turns
into (my favourite):
virsh # start fedora
error: Failed to start domain fedora
error: operation failed: the printer thinks its a router.
