Hi, Here is a little patch that attempt to fix the issue regarding xen_platform_pci=0 not been handled. There is one patch left from the previous version. The patch that was adding qemu_machine_override have been removed as it is unnecessary. If someone wants to change the -machine, it can always add it to device_model_args_hvm, as QEMU appear to use the last one. Regards, Anthony PERARD (1):

The user has the option of disabling the platform driver: 00:02.0 Unassigned class [ff80]: XenSource, Inc.

I tried setting xen_platform_pci=0 on my test ubuntu 11.10 livecd VM hoping it would run in HVM only mode, but the guest''s logs showed it detecting the Xen host and loaded the PV netfront driver (after modprobe). Is this expected behavior? Is there no way to force HVM only and not PVHVM or total PV? Setup: Xen Unstable Qemu Upstream Thanks, David

This patch series provides the facility to eject and insert a cdrom when the used device-model is qemu-xen. The only difference between both device-model is a call to a QMP command as `xl cd-insert ...` will still update xenstore, even if it''s not used by QEMU.

Hi everyone, after following in the footsteps of the following discussion (http://lists.xenproject.org/archives/html/xen-users/2013-09/msg00106.html) I had been able to turn my GTX 480 into a Quadro 6000. When I VT-d passthrough it to a Debian jessie VM it shows up fine and CUDA 5.5 seems to function properly up to a point: lspci -v: 00:04.0 VGA compatible controller: NVIDIA Corporation GF100GL

Coding style has recently been changed for libxl. The convenience macro LOG() has been introduced, and invocations of the old macro LIBXL__LOG() are to be replaced with it. Change occurences of the old macro to the new one in the functions qmp_handle_response() and qmp_handle_error_response(). The new macros need access to a local libxl__gc *gc, so add it as a parameter to both these functions,

This hotplug state will be used to remove a device without the guest cooperation.

Hi All, We did some testing for Xen-unstable tree with upstream QEMU. We covered basic guest booting up, power management, VT-d, SR-IOV features. We found 4 new bugs which only exist in upstream QEMU not in qemu-xen. We followed the below wiki page to use upstream QEMU. http://wiki.xen.org/wiki/QEMU_Upstream test tree: xen-unstable-tree.hg: C/S 26193 (about 20 days ago) qemu.git: commit

This moves the xen_modified_memory call from cpu_physical_memory_map to cpu_physical_memory_unmap because the memory could be migrated before the device model have written to it. But because we need to know the guest address and to avoid rewriting a new function, the call is moved to qemu_invalidate_entry. So this later has to new parameters, the length of the mapping and if it was a write.

Greeting, We are about to update the centos-release-xen package to point to Xen 4.8 rather than 4.6. I'll push the update next week. As a reminder, you can "pin" your installation to Xen 4.6 by installing centos-release-xen-46 and then removing centos-release-xen. And for the more adventurous, that update will come with a new package centos-release-xen-410 to install Xen 4.10.

When read() return 0, the current code just tries again. But this leads to an infinite loop if QEMU died too soon. Also, retry select if a signal was caught.
