Re: [CentOS-virt] xen and spice problem

[Christoph]

Hi

till now it are the rpm's with spice support working without problems 
(spice works to :) )


there is one issue what I have found, after install does grub2-mkconfig 
make this entry:


multiboot   /boot/xen-4.6.0-rc-2.el7.gz placeholder...

but I think it should be:

multiboot   /boot/xen.gz placeholder ...

with the first one it doesnt boot here, grub cant find it allthough its 
there in fs...

OK, I've done a build of 4.6rc4 with spice enabled.  You can install
it with --enablerepo=virt-xen-46-candidate; I haven't done any testing
on it at all (all our test  boxes are being moved today).

Let me know how it works for you.

above is a build of upstream xen with this `configure` including spice
support:
./configure --enable-systemd --prefix=/usr --enable-xsmpolicy
--enable-ocamltools \
 --libdir=%{_libdir} --enable-efi \
 --with-extra-qemuu-configure-args="--enable-spice --enable-usb-redir"

there is no associated libvirt build
Included are patches up to the HEAD of staging-4.6, so its basically

why is the spice support not in the 'offical' xen centos7 repo built in?

No, the qemu version will be one that is custom build for the xen package.

Fabio, is there a toplevel config option to enable spice when building
through the Xen build system?

Please manually CC me if you can, as I'm not getting your mails to
centos-devel...

Qemu seems crashed, can you post qemu log of this domU for see the

Also domU's xl cfg can be useful and/or backtrace of qemu crash with

thats the config of domU:

where/how I can see the qemu log?
