Re: [Xen-devel] libxl: error: libxl_dm.c:1212:device_model_spawn_outcome: domain 1 device model: spawn failed (rc=-3) when creating VM using upstream qemu on Xen 4.2.

[Fabio Fantoni <fantonifabio@xxxxxxxxxx>]

Hello,

I've tested Xen 4.2 on CentOS 6.3(x86_x64)

My goal is to connect to Windows VM on Xen 4.2 using SPICE client.

Installation of Xen 4.2 was successful. 

Also creating Windows VM using qemu-dm and connecting to it using VNC are OK.

But qemu-dm can't support SPICE, so I installed upstream qemu. (http://wiki.xen.org/wiki/QEMU_Upstream)

I also installed spice-server and spice-protocol as newest version.

Configuration and installation seems like successful. But not work with error message above.

Hi, is also my goal have spice working on xen, is over one year that I'm testing it.
Now the main problem for me is a qemu crashes when running spice + qxl.
Start trying build with internal qemu upstream instead of external one (I did the same), see patch below and remove on domU cfg the qemudm override:
