Fedora :: Kvm Shows (vmx) In /proc/cpuinfo But Can't Load Into Kernel?
May 13, 2011
I have fedora 14 installed and wish to use/learn kvm. I installed via groupinstall the virtualization group. I see vmx in /proc/cpuinfo. but when I start virt-manager I get a message that kvm is not installed or cannot be leaded into the kernel (to make a long message short). I am at a loss here as to what to do. I run cat /proc/modules and see "kvm 257420 0 - Live 0xffffffffa022a000". also after running modprobe kvm I run [root@fed14 ~]# lsmod | grep -i kvmkvm 257420 0 and see kvm there.
Is there a simple way to determine the CPU socket from the output of /proc/cpuinfo. Determining the type of processor is simple enough, but the processor I have (Celeron) has two different possible sockets. The output of /proc/cpuinfo is:
processor : 0 vendor_id : GenuineIntel cpu family : 15
[Code]...
I've looked on the Intel processor finder web site with appropriate filters, but the stepping values do not appear to match anything.
My CPU has 2 cores, so I can see two parts in /proc/cpuinfo.But, I want to know if CPUs that support Hyper-Threading (or similar tech), will /proc/cpuinfo give CPU info per core or per thread (or call it sibling)?I only know that Windows Task Manager will give CPU usage statistics per thread if the CPU supports HT.
I recently built a new computer. For CPU, I am using AMD Athlon II X2 @ 2.8GHz... However, when I do cat /proc/cpuinfo, I get the following:
processor : 0 vendor_id : AuthenticAMD cpu family : 16 model : 6 model name : AMD Athlon(tm) II X2 240 Processor stepping : 2 cpu MHz : 800.000 cache size : 1024 KB
and same thing for processor: 1 Notice that for cpu MHz, it says 800.000. However, that is not correct... Shouldn't it say 2800? Is this a bug? Am I looking at this wrong?
I'm trying to retrieve a single string or value from /proc/cpuinfo, but when I try to extract the model (not the model name) the model name comes with it, also it likes to print it twice...
There is a computer with two "Xeon(R) CPU X5550 @ 2.67GHz" CPU. The Hyper-threading is enabled, so it looks like 16-core system, but really there is only 8 physical cores.
I know that when hyperthreading is enabled, each physical core is splitted into two virtual cores. I want to know, which pair of virtual cores shares a physical core and which are not. Or, how (in what order) will Linux enumerate HT-cores comparing to real cores. (enumerating is done for sched_setaffinity and taskset masks).
I have a dump of /proc/cpuinfo file from the system.
I think there are possible:
CPU0-CPU7 are not sharing phys. core. CPU8-CPU15 too. But sharing is in pairs CPU0+CPU8, CPU(i)+CPU(i+8) and so on. or CPU0+CPU1 are from single physical, CPU2+CPU3, CPU(2*i)+CPU(2*i+1). or exotic CPU0+CPU15 sharing, CPU1+CPU14 ... or random?
The hard moment in this case is that there are 2 physical dies of CPU (two sockets), and usual recommendation of using "physical id:" field can't help
The cpuinfo:
processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Xeon(R) CPU X5550 @ 2.67GHz
I have found that APACHE or 'httpd' is installed in my machine. But the problem is I can start or stop the httpd but whenever I load the url http://localhost in Mozilla it shows a page load error.I have done this ,
$ /etc/init.d/httpd start then this $ /etc/init.d/httpd graceful
I reinstalled fedora the other day, and it's been working just fine, apart from the internet. It shows that I have a full connection with the wireless network, but it's really difficult to actually load a page. 80% of the time it just fails and shows "Page Load Error". It's really frustrating because it is connected to the internet. In fact, the icon in the address bar even loads from the site I try to access, but websites just will not load.
I've tested my wireless internet with another laptop which is running vista, and it works perfectly on that. Also, I'm running Fedora 10 on an Acer Extensa laptop.
I've got the F13 LiveCD that I was able to boot and use using the "nomodeset" boot option. From the desktop I'm trying to perform an Install to Hard Drive. I've read the Install from LiveCD post regarding the creation of a /boot partition and a / root partition. I've tried creating them without the LVM group and with. But every time I appempt to install I get...
An error occurred mounting device proc as /proc: mount failed: (9, None). This is a fatal error and the install cannot continue.

I am trying to edit the file shmmax in proc/sys/kernel/. I want to increase the value. I am using vim to edit it. But when I try to write and close the file I get the following error: "shmmax" E667: Fsync failed Press ENTER or type command to continue

I have read that this can be cause by a full disk. I checked with df and have plenty of space available.
How do I get modules in the Kernel to load automatically at boottime? I''m specifically trying to get i810fb to load during the boot process. In Ubuntu, I just had to edit a file and update my initramfs. How do I do this in Fedora?
im trying to install the driver for my nvidia GeForce 7300 GS.i have Fedora 12 installed in an Intel duo core 2 processor 64 bits.kernel installed is 2.6.31.5-127.fc12.x86_64...i followed leigh's guide i did the 4 steps but after reboot screen goes blanck and X dont work.the log says:
-> Kernel module load error: insmod inserting './usr/src/nv/nvidia.ko' -1 no such device
I think I know quite well what my problem is. However, I'm still too much of a newbie to know how to solve it.My problem: I no longer get a login screen on my server after I ran a yum update which updated my kernel (thank god, vnc server still works).Cause: During startup Fedora complains that it can't load the module nvidia.ko. Reason: The module doesn't match the current kernel.
For a diskfull node (the OS installed in a disk), I can use the 'insmod' command to insert a kernel module into the kernel. And after the reboot, the module is still in the kernel. I have a question here: how, when and which kernel module will be loaded in the boot up process for a diskfull node?And for the diskless node, can I use the chroot or some other ways to install the kernel modules into ramdisk, so that kernel module can work when the diskless node boot up? I think it needs certain mechanism to load the kernel like the boot up of diskfull node.
I'm new to Ubuntu and i set up my wireless myself and I think I may have put in wrong settings. I looked through the forum and found these commands to put in the terminal from other posts. Could someone please see if they can fathom what I've done wrong. I have an wG111v2 netgear usb which works fine in windows but is very sluggish on Ubuntu. It worked for a while but since i have deleted and reinstalled my wireless numerous times I now can't get iternet at all. I have Ubuntu 9.10 on my machine which I duel boot with winXP.

I was just wondering why my Dual-core Processor shows basically a mirror image where CPU core loads cross. On something like a file transfer, shouldn't they both be at the same level?
I am an experienced Linux admin and have been using SuSE for many years. My development machine has had every version of SuSE since '02 and although it is a little old, is in good working order. (AMD 2400, 2 gig RAM, 160 Gig IDE disks - SuSE on disk 2) (OpenSuSE 11.1 with the latest kernel works perfectly. This install is on a spare HDD prior to doing a full install on my usual HDD.)
When I try to install SuSE 11.2 from DVD, the load kernel operation hangs at 97% (using both normal and safe kernel), however, I can install from live CD without any problem. I have tried the same DVD on a few "older" machines and had the same problem. I initially thought it was the actual DVD but re-burning has the same problem. I have also tried another DVD writer - same problem.
Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.
I use Linux Mint, and I installed a linux-rt from the repository, but when I restart my computer no grub menu shows up. It just boots linux mint. How can I get it to show the menu so I can choose the real time kernel?
today i install centos x86_64 in my server, but /proc/cpuinfo display 2000Mhz . My processor model name : Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz, before the server had centos i386 and display 2800Mhz.
i have problem with samba share everytime when i want to browse shared folders on fedora machine from windows i always get this msg (SELinux is preventing samba (smbd) "getattr" to /proc/fs/nfsd (nfsd_fs_t).)here is my selinuxlog

I had Fedora 7 and Windows Vista dual booting on my computer. I just installed Fedora 10. When the live CD asked me where to install it, I chose "Remove all Linux Partitions and create default layout" The installation went perfectly, but now when reboot my computer, it boots directly into Fedora; GRUB does not load to ask me which OS I want to load. I know I did not overwrite Vista because I can still view my Vista files through Fedora. Here is my grub.conf file:

What do I need to do to make GRUB load again upon booting?
Following a zypper dup and turning my computer off for a few hours; when I rebooted, I got a message saying, "error: you need to load the kernel first press any key to continue . . . " And then it goes back to the grub menu for of the same if I select openSUSE 11.2.SystemrescueCD won't boot it. I've tried to "repair installed system" and "rescue" with my openSUSE 11.1 DVD -- it won't even acknowledge (as it were) the presence of 11.2 or the system on the other hard drive (though it does recognise the partitions).The PCLinuxOS 2009 KDE and GNOME live CDs will redo the MBR of installed systems (at least, as far I know, PCLinuxOS is one of systems). In my experience, the 11.2 live CD won't. I was hoping the 11.1 DVD would. What to do?
I m new user for Ubuntu..I m using ubuntu for last 5 Months.I love very much and also i m spreading ubuntu community in my place.I have a problem now to use Ubuntu.When i on the ubuntu...Its says in grub kernel is not load...
I can choose which kernel I want to boot by default, instead of having to hold the shift key down every time I want to choose the kernel I want to boot into. I am running multiple kernels.
