[PATCH 0/5] x86/vmware: Steal time accounting support
Hello, This patchset introduces steal time accounting support for the VMware guest. The idea and implementation of guest steal time support is similar to KVM ones and it is based on steal clock. The steal clock is a per CPU structure in a shared memory between hypervisor and guest, initialized by each CPU through hypercall. Steal clock is got updated by the hypervisor and read by the guest.

DRBD + Remus High IO load frozen
Dear all, I have installed DRBD 8.3.11 compiled from sources. However the backend block will freeze if there is high IO load. I use Remus to support high availability and checkpointing is controlled by remus for each 400ms. If I check the Iostat I got the idle CPU will decreasing extremely each checkpointing and when its reach 0% of idle cpu the local backing device will freeze and damage the

Call Stealing
Hi All, I'd appreciate some help on how to implement "call stealing". That is, where you dial a code to redirect any call on the system to your handset. I'm getting rid of my BRI service and I'm trying to replace the functionality of my existing ISDN2e PBX (Cybergear Gold) with VOIP and Asterisk. On my ISDN PBX, the short-code *46 does this. For example, if I take a call on

[PATCH v10 12/19] unfair qspinlock: Variable frequency lock stealing mechanism
In order to fully resolve the lock waiter preemption problem in virtual guests, it is necessary to enable lock stealing in the lock waiters. A simple test-and-set lock, however, has 2 main problems: 1) The constant spinning on the lock word put a lot of cacheline contention traffic on the affected cacheline, thus slowing tasks that need to access the cacheline. 2) Lock starvation is a

Call stealing
Hi, How can I (through the manager interface) steal a call from one phone, and transfer it to another? Does asterisk provide for actions like this? It's a common action in Lucent systems it seems.

How to steal an answered call?
Hello, I'm familiar with Pickup/PickupChan for taking a ringing call, but does anyone know how a phone can "steal" an already answered call from another phone? Our users have decided that call parking is too long-winded and don't want to use that. For example: phone A calls phone B, phone B answers the call, phone C dials something to "steal" the call from B, and

[PATCH v7 08/11] x86, kvm/x86.c: support vcpu preempted check
Support the vcpu_is_preempted() functionality under KVM. This will enhance lock performance on overcommitted hosts (more runnable vcpus than physical cpus in the system) as doing busy waits for preempted vcpus will hurt system performance far worse than early yielding. Use one field of struct kvm_steal_time ::preempted to indicate that if one vcpu is running or not. Signed-off-by: Pan Xinhui

How to protect your code? Obfuscater?
I just made a rails application that I plan to sell and dsitribute. I want to distribute it without having to worry about someone stealing the code and selling their own version. How do I do this? Is there a ruby obfuscator or anything that can keep someone from seeing the code? Thanks for your help. -- Posted via http://www.ruby-forum.com/.
