The following two patches allow the parallel use of memsharing, xenpaging and xen-access by using an independent ring buffer for each feature. Please review. v2: - update mem_event_check_ring arguments, check domain rather than domain_id - check ring_full first because its value was just evaluated - check if ring buffer is initialized before calling mem_access_domctl/mem_paging_domctl

Hi, All Intel QA conducted a full validation for xen 4.1 rc1, it includes VT-x, VT-d, SRIOV, RAS, TXT and xl tools testing. 24 issues were exposed. Refer the bug list, please. We already assigned 14 bugs to Intel developers (which has an ''Intel'' tag in the bug title), most of the rest 10 bugs are related xl command. For the these bugs, need community''s help to fix

The following two patches are about how to speed up in xenpaging when page in pages. On suse11-64 with 4G memory,if we page out 2G pages,it will cost about 15.5 seconds, but take 2088 seconds to finish paging in.If page-in costs too much time,it will cause unmesurable problems when vm or dom0 access the paged_out page,such as BSOD,crash. What鈥檚 more,the dom0 is always in high I/O pressure.

ging_prep ensures that an mfn is backing the paged-out gfn, and transitions to the next state in the paging state machine for this page. Foreign mappings of the gfn will now succeed. This is the key idea, as it allows the pager to now map the gfn and fill in its contents. Unfortunately, it also allows any other foreign mapper to map the gfn and read its contents. This is particularly dangerous

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. The first patch modifies creation of the hvmloader key in xenstore and adds creation of a new read/write hvmloader/generation-id-addr key. The second patch changes hvmloader to use the new key (as

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. The vast majority of the code is in second patch. The first patch merely changes the xenstore key name used by hvmloader to store the buffer address.

This patch set adds XSM security labels to useful debugging output locations, and fixes some assumptions that all interrupts behaved like GSI interrupts (which had useful non-dynamic IDs). It also cleans up the policy build process and adds an example of how to use the user field in the security context.

Hi all, this small patch series fixes the build breakage introduced by f1dbf015dfb0aa7f66f710a1f1bc58b662951de2 with Xen < 4.2. The problem is that xc_hvm_inject_msi is only defined from Xen 4.2 onwards so we need to provide a compatibility function for older Xen versions. Stefano Stabellini (2): xen,configure: detect Xen 4.2 xen: add a dummy xc_hvm_inject_msi for Xen < 4.2

The following is a revised patch series to add support for a VM generation ID virtual device for HVM guests. The basic requirements of this device are as follows: - It must be exposed somewhere in ACPI namespace with a _CID of "VM_Gen_Counter". - It must also include a _DDN of "VM_Gen_Counter". - It must contain a _HID object but no particular value is required. - It must
