similar to: A special kernel for linux as guest os

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

Dear CentOS lovers, Is someone interested in the linux-2.6-smarter-relatime.patch for centosplus kernel? This patch solves disk I/O performance dramatically on servers, And recent distributions (fedora9 and later, etc.) and official kernel applies it. RHEL6 may include it, but RHEL5 is not. How about the linux-2.6-smarter-relatime.patch? Best Regards, Yuji

Hi , I am using Centos 5 for virtualization , i have installed Centos 5 as Host OS and trying install Centos 5 as a guest OS but system is stuck at final screen Starting Install process. This may take saveral minutes...... and its not doing anything else after that i am waiting for at leat 30-40 minutes. Kernel and Hardware details are as follows: Kernel Linux xen 2.6.18-8.el5xen #1 SMP

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

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 ".

Hello, The XEN kernel in "XEN RELEASE-4.0.1" is shipped with the following config parameters: CONFIG_HZ_1000=y CONFIG_HZ=1000 At many blogs and forums there is a discussion that the CONFIG_HZ parameter should be changed to 250 HZ or 300 HZ. We will operate a DomU and the Dom0 with the same 1000HZ Kernel. Is this setup possible and recommended. How high is the performance cut-off?

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 there! I appear to be having problems with trusted domains using 3.0a21. Using Samba as a member server, as user "nirs" on domain "Exanet-il" I am unable to log on to a member server ("snow") who is a member of the "Exanet-qa" domain. The "exanet-qa" is supposed to trust "exanet-il", and it all worked with 2.2 . This is the relevant

Hello, I have read over all of the FAQ's I could find, read all of the documnetation that I could find and still I cannot find an answer to the following problem. When I use the smbclient to check to see if Samba is working correctly I get the following response. This is running on Solaris 7 on a Sun box. If you need any other info please let me know. Any help would be very much

Hello, which .tdb files in /var/lib/samba are safe to remove (rebuilt automatically)? Long story: I have posted a couple of times lately regarding some mysterious freeze effects we've been having on the clients. We have now tried 2.2.4, 2.2.7a (this one makes it even worse) and 2.999 (3.0 pre-X) and have the same trouble on all. It seems the same configuration does NOT cause this

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 compilation error when CONFIG_PCI_REASSIGN is not set. The patch depends on following patches I have sent.

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.
