similar to: Xen on CentOS 6.4

I just did a yum update on a CentOS 7 / Xen 4.6 server which took me from kernel-3.18.34-20.el7.x86_64 -> kernel-3.18.44-20.el7.x86_64 After rebooting, the following notice is printed immediately upon xl create'ing a domain: libxl: notice: libxl_numa.c:499:libxl__get_numa_candidate: NUMA placement failed, performance might be affected Indeed performance is significantly degraded. This

Hello Dovecot list, We've been running a really old CentOS 5 server with the stock dovecot from yum (1.0.7) for years and years with absolutely no problems. If it ain't broke, don't fix it, or something like that. Well it finally broke, but only due to the server no longer being able to handle the load of the increasing user base (many thousands now, with hundreds of concurrent

I have migrated KVM VMs from a CentOS 6 to a CentOS 7 host. All work fine post-migration, CentOS 3 (don't ask ...), CentOS 6, CentOS 7, Windows. But the CentOS 5 VMs failed. At some point during the boot process, they became unpingable and also inaccessible. I have correlated this to the start of the irqbalance service and was wondering if it is generally considered best practice to turn it

Hi, In general, PV tends not to be supported in newer distribution releases. This is mostly due to HVM performance and flexibility nowadays, which just was not the case back in the days when PV ruled. I am curious why you are trying PV. -yoctozepto On Sat, Sep 19, 2020 at 6:41 PM 9f9dcad3f78905b03201--- via CentOS-virt <centos-virt at centos.org> wrote: > > All, > > Just

Solved. For the archives: Noticed in xl info output that only 1 core was recognised, even though nr_cpus should show 16 on this box. Tried rebooting and selecting the old .34 kernel, console printed "smpboot: do_boot_cpu failed(-1) to wakeup CPU#1" and CentOS failed to boot. Powered down the box fully and started back up with the latest .44 kernel and everything is working fine

Hi, We use a git submodule for gnu-efi. What would be the downside of changing git clone git://repo.or.cz/syslinux.git into git clone --recursive git://repo.or.cz/syslinux.git on the Syslinux wik?

I''m trying to get some answers as to why I (my company actually) would go with RoR over TurboGears. The developer staff is fluent in both Ruby and Python so that is not an issue. Rails is well into its release cycle whereas Turbogears won''t be at 1.0 until later this week. They both do essentially the same thing and they both have cool features unique to themselves

I have a working Samba 4.0.0 AD DC running and am able to manage users etc using the Windows tools. Great. Now I want to as much as possible eliminate the need for an additional directory service (OpenLDAP and/or Open Directory) if not entirely. I need automount working and Posix users. I believe it's possible to set this up but haven't been able to find any solid documentation - Can

Hello Asterisk Users, Hope you all doing fine! I am working with a quite complex dialplan, and I've come to some situations where it makes some nasty use of pre-bridge handlers. The pre-bridge handlers wiki (https://wiki.asterisk.org/ wiki/display/AST/Pre-Bridge+Handlers) doesn't have the big warning the pre-dial one has indicating it must return and must not put the caller/callee in

I'm trying to use my copy and whenever I reboot I have to reconfigure everything again using vmware-config.pl. Any idea why I might have to do this? Is there something about the way services are setup under CentOS 4 or something? Preston

Dear useRs, I have written a function that implements a Bayesian method to compare a patient's score on two tasks with that of a small control group, as described in Crawford, J. and Garthwaite, P. (2007). Comparison of a single case to a control or normative sample in neuropsychology: Development of a bayesian approach. Cognitive Neuropsychology, 24(4):343?372. The function (see

I am having trouble doing the following. I have a data.frame like this, where x and y are a variable that I want to do calculations on: Name Year x y ab 2001 15 3 ab 2001 10 2 ab 2002 12 8 ab 2003 7 10 dv 2002 10 15 dv 2002 3 2 dv 2003 1 15 Before I do all the other things I need to do with this data, I need to summarize or collapse the data by name and year. I've

Dear Rusers, I tried to implement a function comparing mean scores between one subject (the patient) and a group a control subjects. The function returns attended results, but I also obtained the following warning : Warning message: the condition has length > 1 and only the first element will be used in: if (substr(fp, 1, 1) == "<") fp else paste("=", fp) Maybe

I have a question regarding application of model coefficients between datasets. In particular, I have several datasets which I would like to apply a model estimated from only a single dataset (sort of a crude - out of sample application - to show the variances). lets say, names(a) [1] "stdnoi" "momentum" "tbm3" "metcons" "premium"

My wife does and here's the problem. It automatically mounts the flash memory of the player. But it doesn't mount the SD card slot. I used Ubuntu 5.10 recently and it mounted both of them. Both as separate USB sticks. How do I get CentOS to do the same thing? Or can it not discern that two USB flash devices are plugged in? Preston

Folks, I'm trying to configure my dovecot installation to require client certificates for external/Internet connections, while still allowing my local network to not need certificates. This configuration is for Dovecot 2 (2.0.8 in Fedora 14), and I've tried to use the "remote" block to give different definitions for my local network vs the defaults. While most options seem to

Greetings - I will be getting a new server for my company in the next few months and am trying to get a better understanding of some of the basic theoretical approaches to using Centos KVM on a server. I have found plenty of things to read that discuss how to install KVM on the host and how to install a guest and setup the network bridge, and all the other rudimentary tasks. But all of

So I did a fresh install today. Decided to go ahead and upgrade. Everything seems okay save for three problems. #1 - I get a message during boot saying that an Intel microcode update didn't work. Something about not being able to find /proc/microcode. #2 - I can't use the Firefox extension HTML Parser. Anyone use this. #3 - Off and on GDM crashes and I get dropped into a prompt. Any
