[libvirt] Performance about x-data-plane
by Weiwei Jia
Hi,
With QEMU x-data-plane, I find the performance has not been improved
very much. Please see following two settings.
Setting 1: I/O thread in host OS (VMM) reads 4KB each time from disk
(8GB in total). Pin the I/O thread to pCPU 5 which will serve I/O
thread dedicatedly. I find the performance is around 250 MB/s.
Setting 2: I/O thread in guest OS (VMM) reads 4KB each time from
virtual disk (8GB in total). Pin the I/O thread to vCPU 5 and pin vCPU
5 thread to pCPU5 so that vCPU 5 handles this I/O thread dedicatedly
and pCPU5 serve vCPU5 dedicatedly. In order to keep vCPU5 not to be
idle, I also pin one cpu intensive thread (while (1) {i++}) on vCPU 5
so that the I/O thread on it can be served without delay. For this
setting, I find the performance for this I/O thread is around 190
MB/s.
NOTE: For setting 2, I also pin the QEMU dedicated IOthread
(x-data-plane) in host OS to pCPU to handle I/O requests from guest OS
dedicatedly.
I think for setting 2, the performance of I/O thread should be almost
the same as setting 1. I cannot understand why it is 60 MB/s lower
than setting 1. I am wondering whether there are something wrong with
my x-data-plane setting or virtio setting for VM. Would you please
give me some hints? Thank you.

[libvirt] [PATCH] disk: Fixup error handling path for devmapper when part_separator='yes'
by John Ferlan
https://bugzilla.redhat.com/show_bug.cgi?id=1346566
If libvirt_parthelper is erroneously told to append the partition
separator 'p' onto the generated output for a disk pool using device
mapper that has 'user_friendly_names' set to true, then the error
recovery path will fail to find volume resulting in the pool being
in an unusable state.
So, augment the documentation to provide the better hint that the
part_separator='yes' should be set when user_friendly_names are not
being used. Additionally, once we're in the error path where the
returned name doesn't match the expected partition name try to see
if the reason is because the 'p' was erroneosly added. If so alter
the about to be removed vol->target.path so that the DiskDeleteVol
code can find the partition that was created and remove it.

[libvirt] [PATCH 00/11] Adjust build/start format checking for fs, disk, and logical backends
by John Ferlan
Two of these patches (2 and 10) are followups to no-overwrite patches
previously posted (I left links in the patches for reference).
Essentially this series works to unify the probing code from the file
system backend using blkid and the parted format reading code from the
disk backend in one common set of functions.
In doing so, the disk backend will now pick up the ability to use the
blkid 'partitions' APIs in order to "probe" the target device for a
valid/known partition format type. Additionally, the file system
probe will pick up a fallback to the parted mechanism from the disk
backend if the 'blkid' APIs are not built into the system.
A few extra bells/whistles were added for fs pool startup to ensure that
the format in the startup XML matches the format on the target disk,
which is essentially the mechanism the disk backend used (although it
was slightly broken).
Then in order to really pile on, the overwrite logic was added to the
logical pool which didn't have any such checking (both build and start).
Testing was done locally using an iSCSI device and laying down different
formats and seeing what would happen on various usages of the format
(with --overwrite and --no-overwrite).
John Ferlan (11):
storage: Introduce virStorageBackendDeviceProbeEmpty
storage: Fix implementation of no-overwrite for file system backend
storage: Add partition type checks for BLKID probing
storage: Add writelabel bool for virStorageBackendDeviceProbe
storage: For FS pool check for properly formatted target volume
storage: Move and rename disk backend label checking
storage: Adjust disk label found to match labels
storage: Clean up logical pool devices on build failure
storage: Extract logical device initialize into a helper
storage: Add overwrite flag checking for logical pool
storage: Validate the device formats at logical startup

[libvirt] Do different Virgil3D users running have the same CANVAS fingerprint?
by bancfc＠openmailbox.org
Background:
Canvas fingerprinting is a technique to track users based on their GPUs.
https://en.wikipedia.org/wiki/Canvas_fingerprinting
Someone did some testing and the good news is the fingerprint is common
for all users of the same OS across all KVM users because it presents
the same virtual GPU/drivers for everybody.
What I need your help to find out is whether this holds for Virgil3D
users that enable graphics acceleration. (I am running on Debian and the
libvirt version in the repos is too old to have this included also I
don't have multiple machines)
To test this you need:
To run plain FireFox on a virtualized distro (with GL acceleration
enabled in libvirt) of your choice and visit
https://browserleaks.com/canvas . Then repeat the same steps with that
same distro (in a VM) on another physical machine and compare values.
A good result is if you see the same numbers for both machines. That
means the virtual device fingerprint is uniform for all virtual users.

[libvirt] [PATCH 00/12] vbox: remove support for vbox 3.x and older.
by Dawid Zamirski
Hello,
This series removes support for legacy VirtualBox versions (3.x and
older) that did not have upstream support for a while and won't even
work on any relatively recent distro. The idea for doing this was
first mentioned here [1] and this makes the driver code cleaner as
the APIs for those old versions were quite different from v4.0+ and
required abstractions to handle the differences.
Please note that the first patch in the series is sent to ML as a
compressed attachment because it deletes VirtualBox SDK header files
for those old verions which are large and the patch would not pass ML
message size limit.
[1] https://www.redhat.com/archives/libvir-list/2016-November/msg01133.html
Regards,
Dawid
Dawid Zamirski (12):
vbox: remove SDK header files for vbox 3 and older.
vbox: remove calls to *InstallUniformedAPI macros.
vbox: remove code for old API versions.
vbox: remove _vboxAttachDrivesOld
vbox: do not use IHardDisk anymore.
vbox: remove getMachineForSession flag.
vbox: remove domain events support.
vbox: remove code dealing with oldMediumInterface
vbox: IVRDxServer to IVRDEServer.
vbox: fix _displayTakeScreenShotPNGToArray
vbox: consolidate vbox IID structures.
docs: add news entry in improvements section.

[libvirt] qemu-kvm blocked for more than 120 seconds when "libvirt-guests" is enabled
by Oscar Segarra
Hi,
I just have two virtual machines in my environment, I want them to
gracefully stop when host is powered off gracefully.
Nevertheless, system hangs on shutdown:
[root@vdicnode01 ~]# virsh list
Id Name State
----------------------------------------------------
1 vdicdb01 running
2 vdicone01 running
The configuration:
/usr/libexec/libvirt-guests.sh
URIS=default
ON_BOOT=ignore
ON_SHUTDOWN=shutdown
SHUTDOWN_TIMEOUT=60
PARALLEL_SHUTDOWN=5
START_DELAY=0
BYPASS_CACHE=0
CONNECT_RETRIES=10
RETRIES_SLEEP=1
SYNC_TIME=0
[root@vdicnode01 ~]# cat /etc/libvirt/qemu.conf
user = "oneadmin"
group = "oneadmin"
dynamic_ownership = 0
spice_tls = 0
With libvirt-guests service started:
[root@vdicnode01 ~]# service libvirt-guests status
Redirecting to /bin/systemctl status libvirt-guests.service

[root@vdicnode01 ~]#
If I stop locally libvirt-guests (as root) Looks work perfectly:
[root@vdicnode01 ~]# virsh list
Id Name State
----------------------------------------------------
[root@vdicnode01 ~]#
--> Now I start again the virtual machines and the libvirt-guests service
<--
[root@vdicnode01 ~]# service libvirtd restart
Redirecting to /bin/systemctl restart libvirtd.service
[root@vdicnode01 ~]# service libvirt-guests start
Redirecting to /bin/systemctl start libvirt-guests.service
[root@vdicnode01 ~]# virsh list
Id Name State
----------------------------------------------------
1 vdicone01 running
2 vdicdb01 running
[root@vdicnode01 ~]#
But If I shutdown the host it look not work properly (I attack screenshots
of the shutdown process).
Any help will be welcome.
Thanks a lot.
