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.

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

Is it possible to disable the unbond resolver in the asterisk configuration? Or, it is necessary just to disable the module? Best regards, Leonid Fainshtein On Thu, Aug 27, 2020 at 3:29 PM Joshua C.

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.

Hi, Olaf we have tested the xenpaging feature and found some problems. (1) the test case like this : when we start a VM with POD enable, the xenpaging is started at the same time. this case will cause many problems ,finally, we fixed the BUG, the patch is attached below. (2) there is a very serious problem. we have observed many VM crash examples, the error code is not always the same.

Hello, Recently many advanced memory mechanisms are introduced into Xen. One problem we found is the conflict between p2m query and setting. For example, backend drivers always map domU’s page to its own space, during the mapping procedure, situations as follow may happen, when mfn is obtained by gfn_to_mfn(), this mfn is likely to be paged out. first case: grant mapping

hi, How can I get corresponding shadowed page number of a virtual address in vm? -- Best Regards, Mohamad Rezaei

I deleted the res_resolver_unbound.so module, and now it works as expected. So, the problem is related to the 'unbound' resolver? FYI: I'm using Asterisk 16.2 installed from Debian 10 repository.

I am running HTB on a PowerPC platform and using following script to do rate limit. When I set rate of class 1:11 lower than 4mbit, I can get traffic rate close to the setting. However, if I set the rate higher than 4mbit, I will get much lower bandwidth (roughly 4.5mbit) than the setting, no matter how big the setting is. To verify the script, I run it on PC with then I got correct result. Could

Good day, I would like to know if there is an efficient and accurate method for computing the power of a tridiagonal matrix in R? The "obvious" method would be eigen-decomposition, but I find that this is not very accurate, probably because the dimensions of the matrix I am considering are large and the eigenvectors are not well approximated. Here is an example of what I am trying to

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

Hi, I have a couple workstations running WinXP x64 that connect to a few servers running Centos 5.1 with Samba version 3.0.25b. I'm experiencing this really strange problem with two of the boxes. Two of them have 3ware RAID cards with XFS partitions. I export the partion across both NFS and SMB. These are the two that I'm having problems.with. When I save a large file through an

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

This patch series introduces the shared ring used by the front-end to pass request descriptors to tapdisk, as well as responses from tapdisk to the front-end. Requests from this ring end up in tapdisk''s standard request queue. When the tapback daemon detects that the front-end tries to connect to the back-end, it spawns a tapdisk and tells it to connect to the shared ring. The shared

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and
