I have a IBM System x3600 series server with UEFI. I managed to compile the xen EFI (xen-4.2-unstable.efi). The machine is currently running Ubuntu with grub2. I can see a grubx64.efi in /boot/efi/EFI/ubuntu/grubx64.efi Where should I put the xen efi ? I tried creating a efi/EFI/xen/xen-4.2-unstable.efi and added it as a boot option using efibootmgr. All I get in that case is a blank screen. I

The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to

https://bugs.freedesktop.org/show_bug.cgi?id=50121 Bug #: 50121 Summary: [Regression] NV34 Fx5200 fails to resume with commit 5d720f2450 Classification: Unclassified Product: xorg Version: git Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority:

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block
