Hi, I am trying to release domU pages from page_list and xenpage_list after domU shutdown while retaining the rest of the domain information. To achieve this in __domain_finalise_shutdown i call domain_relinquish_resources. This is failing to release pages from page_list for type PGT_l2_page_tables and crashing dom0. To be specific, while testing on mini-os i saw that when

I''m having trouble switching into user mode with my domU kernel -- everytime I call __HYPERVISOR_iret, the hypervisor calls into my kernel via the registered callback handler. None of the bits in the event channel pending arrays are set. If I return via the iret call, the hypervisor immediately calls back into the handler. The user RIP never changes, so it is clearly not making forward

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

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
