Âok, I'm using the Upstream compiled in Xen so I created the file qemu-dbg, chmoded it etc...

But that's as far as I can get:

xl create result:

The problem should solved with this in domU's xl cfg:

If the problem persist look the domU's qemu log.

Fabio, actually I would have to compile qemu-dbg during compilation of xen, right?

Because I uninstalled it for installing 4.5RC4.

If you use qemu compiled in xen is not stripped is you have debug enabled in xen config (enabled by default except stable release).

Qemu packages in debian seems not have -dbg package instead, I not remember if are at least not stripped, if are stripped and without -dbg pkg we should open a bugreport about in debian tracker.

Hello Fabio, well same thing happens with remote-viewer,

about not using dom0 as desktop, it's a laptop I'm using for those tests,

Way to go is to use a blank machine with only Xen and then virtualise all machines inside?

Try to post what version of qemu, spice ecc your are using, your domU xl cfg and backtrace of the crash (following the howto I wrote should be simple)

Fabio,

ok for all concerning rombios ...

My spicec connection keeps on dying with

"Spice-Warning **: red_peer.cpp:128:connect_to_peer: failed to connect: Connexion refusÃe (111)"

Then I can't access VM and have to destroy it.

I'm connecting with

spicec -h 0.0.0.0 -p 6000

Any idea?

spicec is very old and deprecated client and was already removed in spice git for next version.
there are spicy and virt-viewer, the second is better.
from address seems that you use dom0 as desktop, don't seems good for me^^''

if you still have the qemu crash install spice debug package and take a backtrace with gdb.

For use gdb on qemu as it child process is particular.

Small help with gdb of qemu launched by xl:
add the line below in domU's xl cfg:
device_model_override="/usr/lib/xen/bin/qemu-gdb"
vi /usr/lib/xen/bin/qemu-gdb # create the file, change the qemu path if needed
#!/bin/sh
exec gdbserver 0.0.0.0:1234 /usr/lib/xen/bin/qemu-system-i386 "$@"
# after xl create with (qemu gdb), do it fast after xl create when arrive on qemu process launch (before timeout or xl create will fails)
target remote localhost:1234 # prepare this command in other ssh to the xen dom0 and enter on xl create when arrive on qemu launch
c # press immediatly
bt full # when qemu stops with crash

Ok Fabio, thanks to your configure, some bits of hacking the install part and lots of advises/support/encouragements ;) from Mark Pryor I ended up

Âinstalling 4.5RC4 with QXL support on Deb8 unstable.

So now what do you want me to test fabio?

I have win7 x64 / win 2k8R2 vms in test mode ready to install drvers.

the numerous troubles I went through are related in the IRCcopy attached.

I actually couldn't build rombios and used seabios provided by the system -like you-

I should try to compile/find latest qxl now.

rombios is used only by qemu traditional that is very old, without spice support and hvm domUs have lower performance with it.
qxl drivers in latest spice guest tools are signed and not require windows testsigning mode, same for james haper xen gplpv.
If you want test new winpv drivers instead you need it.

For me qxl is working good on w7 domUs except after save/restore when "freeze" 2-3 minutes on screen resolution change and I not found the exact problem for now.
I also not found how to have qxl working in linux domUs, on latest test xorg crash on start with qxl driver installed.
Probably other changes are needed in hvmloader and/or xen hypervisor and/or qxl driver.
Any help testing it is appreciated.
See you in 2K15.

ok, I'm trying to patch the files with yours,

I need to do it manually right?

git apply is not working here.

If the patch need a "refresh" the conflict should be solved manually.
Taking the patch updated from here probably it can be applied to latest 4.5-rc:

There is an error in pageqs describing how to compile from sources as in 4.5

cat .config PYTHON_PREFIX_ARG=--install-layout=deb

is in fact in .INSTALL

If also you use debian you can use make debball that is better for install/remove easy and fast test build.

And for example I use this configure options with xen 4.5:
./configure --prefix=/usr --disable-blktap1 --disable-qemu-traditional --disable-rombios --with-system-seabios=/usr/share/seabios/bios-256k.bin --with-extra-qemuu-configure-args="--enable-spice --enable-usb-redir" --disable-blktap2
I use wheezy building updated packages from sid: seabios 1.7.5-1, spice 0.12.5-1, spice-protocol 0.12.7-1 and usbredir 0.7-1.
If you use jessie instead you have all packages updated.

About python I'm using this workaround (before execute configure) even if probably is not the best:
Config.mk
-PYTHON_PREFIX_ARG ?= --prefix="$(PREFIX)"
+PYTHON_PREFIX_ARG ?=

Hello Fabio,

Sure thing I will help debug the win7 and the win8 versions.

Where to start?

I'll try to see if I can patch with patch from https://github.com/Fantu/Xen/commit/fadecf8d6ee0e8c7e421fafba67aa11879e8b8fe and if not will post result.

can it be installed on my xen stack?

Yes but probably require a small refresh, I always posted the patch based on updated xen-unstable.

Here qxl patch refreshed for xen 4.5 if needed:
https://github.com/Fantu/Xen/commit/fadecf8d6ee0e8c7e421fafba67aa11879e8b8fe

Here the latest spice guest tools for windows with qxl driver included:
http://www.spice-space.org/download/binaries/spice-guest-tools/spice-guest-tools-0.74.exe

Windows >=8 and similar require a new qxl drivers, there are a beta build but latest tried some months ago have serious bug and I not found recent build full working on windows 8.

On xen windows 7 domUs qxl works good except a problem after save/restore and on linux domUs is not working, for now I not found exactly cause and solution.
On mailing list up to 2 years ago you can find many my mails about.
Any help to test it is appreciated.

Sorry for my bad english.
Also, canÂ I get invited at xendevel irc ?
