Hi all, Can Xen hypervisor modify HVM domU's Shadow page table, under the dom0's context, like trapped from dom0's hypercall? I think it have to call 2 functions at least: guest_walk_tables() and flush_tlb_all(). Can these 2 functions called in dom0's context? In my test, if hypervisor tries to modify HVM's shadow page table, it will bring down the whole system. I am not

This fixes a bug in changeset 22526:7a5ee3800417, where the wrong value is read when deciding whether to flush the VTd tables. The effect is minor: in situations where the p2m entry is changed but the mfn is the same, the VTd tables will be unnecessarily flushed. old_entry is left untouched in the second case, since having a present old_entry will cause the an unnecessary check to be taken at

Hi, all Page offline can be used by many purpose, like memory offline, memory power management, proactive action when multiple CE error happen to one page etc. In virtualization environment without guest offline support, we think offline a page usually means replace the old page with a new one transparently to guest. Currently we are trying to add page offline support in Xen environment .

Trying to migrate a 64bit PV guest with 64GB running medium to heavy load on xen 3.4.0, it is showing lot of soft lockups. The softlockups are causing dom0 reboot by the cluster FS. The hardware has 256GB and 32 CPUs. Looking into the hypervisor thru kdb, I see one cpu in sh_resync_all() while all other 31 appear spinning on the shadow_lock. I vaguely remember seeing some thread on this while

This patch series includes a series of bugs related to p2m, ept, and PoD code which were found as part of our XenServer product testing. Each of these fixes actual bugs, and the 3.4-based version of the patch has been tested thoroughly. (There may be bugs in porting the patches, but most of them are simple enough as to make it unlikely.) Each patch is conceptually independent, so they can each

Hi all, I''ve been reading through the code regarding paging --> spending a lot of time in mm/*.*, as well as some of the other parts up a level or two, but I''m still unclear as to some key things. Here''s what I think I know: I think I know how a domain''s shadow page table is first allocated E.G. the hash_table is xmalloc''ed and when it is

Hi, I am really confused about NPT walks for guest page table , and eager to know the details about it. It is treated as data writes even if the access itself is a code read in AMD NPT.I just want to know : is it the same in EPT? Could anyone help me? I would like to know that very much Thank you in advance Bo Ma _______________________________________________ Xen-devel mailing list

This patch series tidies up a few bits ofthe nested p2m code. The main thing it does is reorganize the locking so that most of the changes to nested p2m tables happen only under the p2m lock, and the nestedp2m lock is only needed to reassign p2m tables to new cr3 values. Changes since v1: - a few minor fixes - more sensible flushing policy in p2m_get_nestedp2m() - smoke-tested this time!

Hi, guys Recently I have been doing some research & I''ve got in trouble. I have altered the kernel of domU and put the code section and data section of selinux security server which locate ~/security/selinux/ss into two seperate sections in the final vmlinux image(see below) objdump -h vmlinux vmlinux: file format elf32-i386 Sections: Idx Name Size VMA

We''ve got reports of that change causing HVM data corruption issues. While I can''t see what''s wrong with the patch, I''d suggest at least reverting it from the 3.3 tree (which is what our code is based upon) for the time being.

Hi all, Can some one tell me where phys_to_machine_mapping is being initialized for a domU having paging mode set to PG_translate. I see that, populate_physmap() after calling __alloc_xen_heap_pages only updates the machine_to_physmap but how is the mfn for the allocated page being updated/set for phys_to_machine_mapping?? I see that phys_to_machine_mapping is a #defined to RO_MPT_VIRT_START

Hi, We are running Samba 2.2.5 on RedHat 7.3 rebuild with ldap support. We run Win2k Terminal Server, which provides most of the clients for the samba server. After a fairly long samba server up time (usually a couple of days, but this happened overnight), we end up with some odd entries in the smbstatus output in the "Locked files:" area.... Here is one line of the type I mean:
