This is the follow up of [1]: [PATCH v1 0/3] mm/memory_hotplug: Make virtio-mem play nicely with kexec-tools I realized that this is not only helpful for virtio-mem, but also for dax/kmem - it's a fix for that use case (see patch #3) of persistent memory. Also, while testing, I discovered that kexec-tools will *not* add dax/kmem memory (anything not directly under the root when parsing

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
