VMI timer code. It works by taking over the local APIC clock when APIC is configured, which requires a couple hooks into the APIC code. The backend timer code could be commonized into the timer infrastructure, but there are some pieces missing (stolen time, in particular), and the exact semantics of when to do accounting for NO_IDLE need to be shared between different hypervisors as well. So

Convert VMI timer to use clock events, making it properly able to use the NO_HZ infrastructure. On UP systems, with no local APIC, we just continue to route these events through the PIT. On systems with a local APIC, or SMP, we provide a single source interrupt chip which creates the local timer IRQ. It actually gets delivered by the APIC hardware, but we don't want to use the same local

Critical bugfixes for the VMI-Timer code. 1) Do not setup a one shot alarm if we are keeping the periodic alarm armed. Additionally, since the periodic alarm can be run at a lower rate than HZ, let's fixup the guard to the no-idle-hz mode appropriately. This fixes the bug where the no-idle-hz mode might have a higher interrupt rate than the non-idle case. 2) The interrupt handler can no

Hi, Looks like this patch broke automated builds due to a lack of a matching line in the defconfigs. Below is a patch that makes this a module for xen and xen0, unconfigured for xenU. That might not be the best thing here however. Thanks kurt Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> ===================================================== diff -r cd744c5ec950

In a virtualized environment, virtual machines will time share the system with each other and with other processes running on the host system. Therefore, a VM's virtual CPUs (VCPUs) will be executing on the host's physical CPUs (pcpus) for only some portion of time. The VMI exposes a paravirtual view of time to the guest operating systems so that they may operate more effectively in a

Hello List If i have a PCI=[08:00.0](example) in any DomU config file the xm shutdown <ID> shuts down this DomU and the Dom0! Otherwise i shutdown this DomU from inside the DomU with halt or shutdown -r now, the Dom0 shuts down to. This happend on Xen 3.4.2 and Xen 4.0 (Kernel 2.6.18.8-xen, 2.6.18.8-xen0) The Operating System to Compile xen was Debian Lenny and the Dom0 os. Without

I setup Xen 3.1 on a etch 32 bit box with amd64. I compile the standard Kernel from Xen and on the other way the gentoo 2.6.20 for both dom0 uand domU. The Xen Setup was bridged. But if i download a tar file, i cant extract it cause of the following error: 09:48:35 (8.66 MB/s) - `xxx.tar.gz'' saved [64985129/64985129] tar: Skipping to next header gzip: stdin: invalid compressed

Or how to delegate special PCI devices from domain-0 to dom(u) Hi, I tried to manage some pci devices for dom(u) domains, using the fedora core 5 (xen0/u) and 6-test2 (xen) i686 kernel-xen and kernel-xen-devel rpms: In domain-0 lspci shows the pci device 00:04.01 which should be delegated to dom(u) In dom(u) lspci does not show any information (this seems to be ok) lsmod in dom(u) gives:

This patch removes disk heartbeat's modularity which makes it the default. Without this patch, userspace changes are required. This patch is not intended for permanent application, just to make it easier for users not interested in testing the userspace clustering implementation to use ocfs2. In order to switch to user clustering, use "o2cb offline" to shut down the cluster,
