Hi,     I use follow code get xenstore ring and event channel, then i wrapped writing and reading function to operate it ,but it came to oops:     struct xenstore_domain_interface {     char req[XENSTORE_RING_SIZE]; /* Requests to xenstore daemon. */     char rsp[XENSTORE_RING_SIZE]; /* Replies and async watch events. */     XENSTORE_RING_IDX req_cons, req_prod;     XENSTORE_RING_IDX rsp_cons, rsp_prod;     };     struct xenstore_domain_interface *xenstore;     xen_hvm_param...

Hi, This patch series fixes the S3 resume of a domain running xenstored and a frontend over xenbus (xen-netfront in my use case). As device resume is happening before process resume, the xenbus frontend resume is hanging if xenstored is not running, thus causing a deadlock. This patch series is fixing that issue by deferring the xenbus frontend resume when we are running xenstored in that same

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen

Hi, This is the Xen implementation for the paravirt_ops interface. The series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked in -mm with a view to being merged in 2.6.23. The first part of the series is some small changes to the core kernel. Apart from the new code added in "Allocate and free vmalloc areas" (posted many times before), they are simply a few one-liners

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
