Once stop_machine() is gone from the CPU offline path, we won't be able to depend on disabling preemption to prevent CPUs from going offline from under us. Use the get/put_online_cpus_atomic() APIs to prevent CPUs from going offline, while invoking from atomic context.

Hello community! I need help with a problem I haven''t been solved with the network team. I manage a network that has over a thousand computers, and the most of the servers are virtualized over Debian / Xen by me. The specific issue arises when I try to set up a DomU HVM running Debian Squeeze, the VM doesn''''t recognize the network but it runs. It gives an error

X86: Fix mce offline page bug c/s 19913 break mce offline page logic: For page_state_is(pg, free), it''s impossible to trigger the case; For page_state_is(pg, offlined), it in fact didn''t offline related page; This patch fix the bug, and remove an ambiguous comment.

Hi, I''ve installed the RPM for Xen 3.3.1 from Gitco for Centos 5.2. I actually did try to compile it directly from source before that with success but as I were having an issue (which I now know is the same), I decided to use the work from somebody else hoping it was a problem specific to my compile. As a summary, I have a dual core Intel CPU with 3 GB of RAM and this kernel running:

without starting vm, we did decompression stress test. harddisk offline did not happen. when some vms are running, we did decompression stress test. harddisk offline happened frequently. We suspect that system interruption loss causes the problem. did anybody meet this problem? or have an idea? our env : hardware : Intel(R) Xeon(R) CPU E5520 @ 2.27GHz SCSI storage

Hi, Keir, Thanks for checking in cpu online/offline support. Another thought inspired by Kevin, due to the time sequence that different cpus enter the stop machine context, there is a small window that some kind of softirqs (say softirq_A) are issued to the dying cpu right after the dying cpu has already handled softirq_A in do_softirq before entering stop_machine softirq. So this softirq_A

Hi, Keir, In debugging the issue "system hang when doing cpu offline", I identified a situation that could cause a dead lock. The scenario is: mwait_idle_with_hint inside play_dead will access per cpu variable, which causes #PF. The #PF handler will use printk, which will schedule a tasklet. In scheduling a tasklet, per cpu variables are needed, otherwise, there will be another #PF.

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 .

we have just upgraded to xen4.0+kernel2.6.31.13. however, we fonud that disk offline in high disk IO(xen4.0+kernel2.6.31.13). but whitout xen4.0, we only start with kernel2.6.31.13, the disk offline didn''t happen. I think it is a bug. test case: 57 physical machine we start 5 vm(cpu:2, memory:1024) in a physical machine.at the same time we do decompression in dom0. tar xzvf *.tar.gz tar

Hi, I just installed R software on my machine which is not supposed to have an internet access. I installed several package that I need, which are quantmod, xts, TTR etc. When I typed require(quantmod), I get " Error: package 'Defaults' could not be loaded". How do you install Defaults package if you don't have an internet access ? Does anyone know where I can find the file

Hello, For those those who speak french and are interested. I wrote a guide about Uml and Xen virtualisation solution for course purpose.
