Spice in unstable

[Fantu]

I see there is spice support in unstable, seem to be a very good vdi and we
want use it on server with xen but I not found documentation about in xen,
only about kvm.

The syntax is also documented in the xl.cfg(5) manpage which is
available online at
http://xenbits.xen.org/docs/unstable/man/xl.cfg.5.html#spice_graphics_support

I suspect it needs device_model_version="qemu-xen" (i.e. upstream qemu)
as well.

Re: Spice in unstable

I have try Precise PV on HVM with qemu upstream and spice but not work.
Dom0 is Squeeze 6.0.4 64 bit with kernel 2.6.32-5-xen-amd64 version
2.6.32-41, xen from xen-unstable.hg changeset 24709:8ba7ae0b070b 

DomU xl configuration file:
----------------------------------------------------------------

apic=1

----------------------------------------------------------------

Without spice the domU starts but vnc is unusable and network doesn't work.

With spice it doesn't start:

spice is not supported by this qemu build.

Is there something wrong on configuration file or are there some bugs?
Thanks for any reply and sorry for bad english.

You shouldn't use xvda/xvdb in HVM guests config file unless you want a
PV only disk, that is OK for a secondary disk but you are not going to
be able to boot from it.
So at least your primary disk should be hda.

Those are quite a serious issues, what kind of guest is this?
I suggest you try to get network and vnc to work without spice before
proceeding any further.
I use upstream qemu with xen rather regularly and I haven't seen these
problems. Could you please post your qemu logs? Does the guest work
correctly with the old qemu?

Your QEMU build doesn't support spice. You might have to compile
upstream QEMU yourself, passing the right option to configure to enable
spice.
The QEMU tree is cloned in tools/qemu-xen-dir by default, give a look at
tools/Makefile:subdir-all-qemu-xen-dir to see the configure options used
by the Xen build system.
Something like this should work:

./configure --enable-xen --target-list=i386-softmmu --extra-cflags="-I$(XEN_ROOT)/tools/include -I$(XEN_ROOT)/tools/libxc -I$(XEN_ROOT)/tools/xenstore" --extra-ldflags="-L$(XEN_ROOT)/tools/libxc -L$(XEN_ROOT)/tools/xenstore" --disable-kvm --enable-spice

provided that you have all the dependencies to build qemu+spice on your
system and that XEN_ROOT points to the xen-unstable directory.
I have to warn you that spice requires lots of libraries in order to
compile succesfully, see:

http://people.adams.edu/~cdmiller/posts/Ubuntu-Lucid-server-qemu-kvm-spice/

Once you manage to do this, maybe you would like to volunteer to update
the wiki with more detailed instructions on how to compile and use SPICE
on Xen? ;-)

Re: Spice in unstable

[Fantu]

I have redo...

Install precise daily build 64 bit with this config:
------------------------------------------------------------------------------
name='PRECISEHVM'
builder="hvm"
memory=1024
vcpus=2
hap=1
pae=1
acpi=1
apic=1
nx=1
vif=['bridge=xenbr0']
#vfb=['vnc=1,vncunused=1,vnclisten="0.0.0.0",keymap="it"']
disk=['/mnt/vm/disks/PRECISEHVM.disk1.xm,raw,hda,rw',
'/dev/scd0,raw,hdb,ro,cdrom']
boot='d'
xen_platform_pci=1
device_model_version='qemu-xen'
vnc=1
vncunused=1
vnclisten="0.0.0.0"
keymap="it"
stdvga=0
sdl=0
------------------------------------------------------------------------------
Vnc is working but have refresh heavy lag and and some partial refresh
problem (I not know good english for explain good), , is near unusable,
network now seem to be working.

After I change boot to 'c', vnc same problem.

Nothing on log about, and vnc on PV domU work correctly.

I tried also with qemu traditional and the mouse is not working (is lock on
center), performance problem persist but there aren't partial image refresh
problem.

About spice need compiled as default, I'll try to do the patch for the
missing parts in build and xl and xen requirements in readme.

Thanks for any reply and sorry for bad english.

I take you are talking about Ubuntu 12.04?

Try to disable Compiz in the guest and/or set stdvga=1 in the config
file. Does it help?

Re: Spice in unstable

[Fantu]

Thanks for reply, stdvga=1 seem to solve some of the more important problem
but not all and not performance/refresh, also try with add videoram=16 but
not improve.
I tried also with compiz disabled and gnome classic instead of unity but
nothing changed.
