Hi,
We're using oVirt 4.3 and want to use spice streaming to better user experience, for
example youtube etc.
I've tried to use before_vm_start script, but lots of problems came out.
1 - on default environmet, hook script returns of no such file or directory, because
python3 does not exist on the system
if i install python3, vdsm stops working
if change interpreter in the script, vdms retuns rc=0 error code hook=114 and it
does not appear on the vm custom properties
So, could you help me to run this hook properly
we've tested
https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/spiceoptions
Master and 4.3 branch returns same error code and nothing appeared on the "custom
properties"
is there anyone who is use it successfully
2 - for this experince is GPU neccessery (not vGPU) , our server has standard 8mb onboard
gpu
thanks

Sorry, I can't help much on the oVirt hook/setup ...
2 - for this experince is GPU neccessery (not vGPU) , our

... but no, you don't need GPU in the host for this feature.
Spice streaming in the host supports two encoders: a mjepg
implementation in spice and a gstreamer one with support to
mjpeg, h264 and vp8. The encoding parameters are hardcoded but
I've tested them all in the past and worked well for youtube-like
scenarios... but feel free to open bugs upstream if not [0]

Good luck with the hook.

So, can you discribe how can i use streaming method on Ovirt 4.3?
do i need to change something on host or engine
I need to solve youtube or other video problems
Additionally, steraming needs to hardware accelerator, all streaming apps or offers
hardware acceletor for best performace
thanks

Looking at the hook you posted earlier:
https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/spiceoptions/before_...
It needs user to provide the options and for this feature to work
streaming=filter or streaming=all must be giving to spice server
to enable streaming.

For mjpeg encoding, you don't need to change anything. For
x264/vp8 with GStreamer, spice must be built with GStreamer
option enabled. You can check if that's the case for your spice
server library by running ldd in the .so file, e.g:
spice (master 717ed19a) $ ldd ~/dev/lib64/libspice-server.so | grep -i gst
libgstreamer-1.0.so.0 => /lib64/libgstreamer-1.0.so.0 (0x00007f393b57d000)
libgstapp-1.0.so.0 => /lib64/libgstapp-1.0.so.0 (0x00007f393b568000)
libgstbase-1.0.so.0 => /lib64/libgstbase-1.0.so.0 (0x00007f393b0df000)
Plus, you need the plugins for encoding in your host.
Additionally, steraming needs to hardware accelerator, all
streaming apps or offers hardware acceletor for best performace
As mentioned earlier, the encoding parameters are hardcoded [0]
so, even if you argue that gpu is preferred, that's not currently
supported but patches are welcome!

Video streaming like Youtube, you should get audio sync, lower
bandwidth, etc.

my first problem is hook file.
When i add file before_vm_start directory and restart engine, it shows under host hooks
file on the web page. But options cannot be displayed under vm custom properties section
if i set spiceoptions ;
engine-config -s UserDefinedVMProperties=spiceoptions=^.*$ --cver=4.3
engine-config -g UserDefinedVMProperties
UserDefinedVMProperties: version: 4.1
UserDefinedVMProperties: version: 4.2
UserDefinedVMProperties: spiceoptions=^.*$ version: 4.3
systemctl restart ovirt-engine
after that under vm custom options shows spiceoptions section. But nothing works.
according to hook file README, needs to be appear options and youtube became more fluent

Hm, could you try instead:
spiceoptions={'streaming':{'mode':'all'}}
engine-config -g UserDefinedVMProperties
UserDefinedVMProperties: version: 4.1
UserDefinedVMProperties: version: 4.2
UserDefinedVMProperties: spiceoptions=^.*$ version: 4.3
I can tell if streaming is enable if you provide qemu cmd line
for what is running (e.g: ps aux | grep -i qemu ...)
systemctl restart ovirt-engine
after that under vm custom options shows spiceoptions section.
But nothing works. according to hook file README, needs to be
appear options and youtube became more fluent
What do you mean with nothing works exactly?

In terms of packages, that can vary a bit due license/patent
code but as quick check, spice's autotools does checks the
following:
https://gitlab.freedesktop.org/spice/spice/-/blob/master/configure.ac#L93
x264enc element is in gst-plugins-ugly while vp8enc and vp9enc in
gst-plugins-good. You can check if you have each of those in the
path by running gst-inspect-1.0, eg:
$ gst-inspect-1.0 vp8enc | head
Factory Details:
Rank primary (256)
Long-name On2 VP8 Encoder
Klass Codec/Encoder/Video
Description Encode VP8 video streams
Author David Schleef <ds(a)entropywave.com>, Sebastian Dröge
<sebastian.droege(a)collabora.co.uk>
Plugin Details:
Name vpx
Description VP8 plugin
