[Spice-devel] SPICE questions

Hi,

What kind of results? -
The bandwith that spice take?
The speed of rendering ? (interactive feeling)
The cpu it cunsom?

as i've written, the problems are speed.

It is even slower compared with "-vga std" option of QEMU.

Regardless if I run the client on the same machine or on a remote Windows machine, speed is always the same.

One point to mention: 

if I move the PPT to another slide it takes several seconds until the screen is updated.

After closing the spice client and restarting it again, the screen is built immediately.

So it seems that it takes a very long time until the spice server gets updated screen data.

Well this for sure not right for any machine that i have saw.
Do you sure you are using the QXL driver? when you go to:
Control Panel -> Display -> Settings

"The Display: " say Red Hat QXL GPU ?
The display says "Red Hat QXL GPU"! 

(There is a issue with windows that you got to change resoultion after you install the
driver in order to benefit from it)

I changed resolution, nothing changed regarding speed.

Thanks

Stefan

I got it compiled and running now!

I had to insert a lot of casts and do some tricking with the libasound library (had to use the 32 bit one) and finally it compiled and even started.

But the results are quite disappointing with a Windows XP virtual machine.

In my virtual machine the "Red Hat QXL GPU" driver is installed as well the "Red Hat Virtual Desktop Interface Port" driver.

Compared with Microsoft Remote Desktop the results are disappointing and even if I run QEMU without the qxl and spice option the results are better.

Has anybody an idea what I am doing wrong, how can I find out what may be the reason?

Another point: the spice client seems to be very unstable in specific situations.

When I opened MS Powerpoint and went to a specific slide with a lot of graphics it regularly crashed without leaving any message. There was no difference whether I used the self-compiled Linux client or the downloaded Windows binaries. 

Especially the speed behavior is important for me to decide if using SPICE is the right way to go and then to possibly contribute where necessary.

Thanks for any help.

Stefan

I don't really know the exact requirements, just read this in the faq.

Its possible that this is fixable, but currently it does not build on

32bit.
