similar to: relatime in plus kernel

Dear Yagi-san, > I heard from the horse's mouth that the CentOS team is working on the > 100Hz centosplus kernel. I think your request triggered the action :-) > They want make people happy. That sounds nice! This TIPS, CONFIG_HZ=100, is one of FAQs. It will make most of us happy. Now we can get kernel-vm package on dev.centos.org. Is it a test release of the special kernel? I

Dear CentOS lovers, Could you consider to include a patch, http://www.psc.edu/networking/projects/hpn-ssh/ for openssh maybe as CentosPlus packages? It has great speed impact for long-distance ( high delay ) transfer. Regards, Yuji Tsuchimoto

The memory relating guest domain should be allocated from NUMA node on which the guest runs. Because the latency of the same NUMA node is faster than that of a different one. This patch fixes memory allocation for Address Translation Structure of VT-d. VT-d uses two types of Structures for DMA address translation. The one is Device Assignment Structure. The other is Address Translation

I assigned FC-HBA to guest domain, but it did not work. FC-HBA seems to write its internal memory which is mapped to host memory space via pci transaction. But there is no mapping in IOMMU''s page table, so that page fault occurs in IOMMU. I think that MMIO resource mapped via p2m table should be mapped via IOMMU''s page table too. In other word, XEN_DOMCTL_memory_mapping

Greetings, I am aware that mounting filesystems with noatime option greatly increases speed. I have tried to follow discussion on the pros and cons of using noatime. I have however not been able to mount with the option relatime in centos 5.2. But in a production db server, which is backed up by HP DP, is it advisable to mount with noatime? Anybody care to share their experience on it?

I am submitting the patch which supports more Capability Structures and Device Specific Registers for passthrough device. In Xen 3.3 unstable, qemu-dm supports Configuration Header, MSI Capability Structure, and MSI-X Capability Structure. But qemu-dm does not support PCI Express Capability Structure, Device Specific Registers, etc (writing them is ignored). To support various I/O devices, I

Hello, This is my first post in this e-mail list and I hope it's enough to justify calling for help. In case it's not, sorry. I'm trying to do analysis and graphics using a factor as a criteria to split data and do the analysis/graphics for each subset of data. Right now what I'm trying to do is to fit and plot the following logistic model, according to a third variable named

This patch adds the function that reassign page-aligned memory resources, to dom0 linux. The function is useful when we assign I/O device to HVM domain using pci passthrough. When we assign a device to HVM domain using pci passthrough, the device needs to be assigned page-aligned memory resources. If the memory resource is not page-aligned, following error occurs. Error: pci: 0000:00:1d.7:

On 32e, we create one guest, then hotplug attach one NIC to guest, guest can not get IP address via dhcp, guest qemu log shows "libpci read error. No emulation ". Here is the bug entry: One 32e, hotplug attaching VT-d NIC to guest failed. http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1316. -- haicheng _______________________________________________ Xen-devel mailing list

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the

Hi I wanted to instal the exellent DVBviewer application for viewing DVB-T-Television under fedora9 / wine? Under WinXP i need to do the following 3 steps: 1) installing the Driver of my technisat DVB-hardware via the windows control-panel 2) installing the software of my technisat DVB-hardware 3) installing the DVBviewer application. So under fedora9 / wine i don't know to to the first step

Hi, I have installed Xen 3.3.1 with Ubuntu 8.04 as dom0 and fedora9 (from jailtime.org) as Dom1. I have more instances of the same fedora9 with separate config files running as other guest domains. But these guest domains dont have any program / application running. So, xm list shows that they are in blocked state as no activity is happening. I wrote a shell script that counts upto large numbers

Hi, I am using rsync for file server mirroring by Linux(Redhat7.2). Please tell me, How to read about rsync last verbose message. wrote 3000000000 bytes read 2000000 bytes 600000.00 bytes/sec total size is 400000000000 speedup is 125.30 "bytes/sec" Is this figure only as a result of a file transfer? Or is it the total result of since the rsync command is performed? I had connected by

This patch fixes libpci error handling. It can be applied to both ioemu-remote and ioemu. libpci returns ALL F when error occurs. Currently, if libpci returns ALL F, emulation stops. But it is possible that the field of real register which is read by guest software is ALL F. After applying this patch, if libpci returns ALL F, ioemu will log warning message and continue the emulation.

libvirt-3.0.0 When attemping to create a virtual machine I receive the error "error : Failed to switch root mount into slave mode: Permission denied”.
