Red Hat / Fedora :: Multicore Virtual Machine On 14?

Mar 17, 2011

I am experiencing a multicpre problem with fedora14 / kernel 2.6.35.6-45.fc14.x86_64 #1 SMP. (standard from the distro). The host has a total of 2 cores .yet a virtual machine started with 'smp 2' ( or xml : <vcpu>2</vcpu>) will not run on 2 pyhs cores . it will use just 1 core ('top' at the host shows 100%cpu while running an endless loop process on the VM) and libvirt 'virsh vcpuinfo <vm name>' shows only 1 physical cpu used (although 2 vcpus are used : 0, 1) The kernel seems to be an SMP one ( so says the uname -a . what does '#1 SMP' mean ?) . Am I missing something ? same XML on a DEBIAN machine will run the VM with 2 phys cores as should although the host there has 4 cores (>2)Should I recompile the kernel src with some addtional flag ?

Ubuntu Servers :: How To Torque On Ubuntu 10.04 On A Single Multicore Machine

Jun 17, 2010

I updated this on jul 21 using comments below Torque is a batch job queuing system that is used on clusters. But I find it handy to use it on my multi-core workstation as well. It allows jobs that need to be run to be schedule by multiple users. The scheduler will make sure that not too many jobs are run simultaneously which could cause high system loads or memory issues. I previously posted how to install torque on ubuntu hardy from the torque source package. However, torque is now in the repositories of lucid and here are the steps that I had to take to get it to work on my workstation.

For this setup I kept the server host name 'torqueserver' which is the default in the package. You can do the same or use a fully qualified domain name. In that case, you will have to adept the steps somewhat. My workstation has 8 cores, and I only want to give 6 of them to the que. Please adapt your numbers accordingly.

0) open root terminal

Code:

sudo -s

1) add torqueserver as an alias to /etc/hosts.

Code:

gedit /etc/hosts
change 127.0.1.1myHostName to 127.0.1.1myHostName torqueserver*) see post by drlemon.

Alternatively use a resolvable host name (check with 'host $HOSTNAME') in the file:

/var/lib/torque/server_name and whereever torqueserver is used below, use that host name

2) install torque from repositories

Code:

apt-get install torque*

[code]....

This works for me but probably requires more configuration in a demanding computing environment. Check out the torque website for more queue configurations, user management etc.

Fedora :: How To Set Up A Virtual Machine

Feb 3, 2011

how do I set up a virtual machine in Fedora 14? Do I do it through Quemu? I did not see Virtualboxose within the repositories. If some one would be so kind as to instruct me (please simple step by step instructions for setting up a virtual machine or for downloading and installing Virtualboxose or any other version of Virtualbox I would forever be indebted to you. I would like to install Fedora on my laptop instead of Ultimate Edition 2.8 of which I am getting tired of any Ubuntu based distribution.Oh by the way I tried the new Gnome 3.0 shell with Laughlin 15 and I was impressed. I can't wait til it is released. Also could someone point me in the right direction as to where I might ask, request, or just offer suggestions for software packages to be placed within the repositories.

Fedora :: Virtual Machine Manager

Jul 30, 2009

I'm having some issues with a windows virtual machine. The system is Fedora 11 and the virtual machine is Windows 2008 Server. If I start the virtual machine from the virtual machine manager, it only has a single cpu despite my setting it to eight. If I start the machine from the command line, I can get four cpus but not eight. In both cases windows seem to display the eight cpus in the device manager (or whatever program it is). It has been suggest that windows was imaged on a four core machine before being loaded on the eight core machine and that something in windows is maxing at four cores. But that doesn't explain why the virtual machine manager can only start one cpu. I just played around on my home machine with a fedora 10 live cd and it recognized the two cores on that machine and used them from the virtual machine manager without problem. Also upped it to three cpus without problem.

Fedora :: Loading Software On Virtual Machine?

Dec 14, 2009

I can create a virtual machine I named vm1 and the virtual-machine manager says it's running.

I don't know how to load windows XP.

The vm1 virtual machine console is frozen with the message "Booting from hard drive." But I know it can't boot from hard drive because I haven't loaded windows XP yet. When I created the vm1 virtual machine I put the windows XP CD in the optical drive and directed the menu to the CD. I heard it running, but still the console is trying to boot from the hard drive. I never got to the point where it asked me any windows XP software loading questions.

Fedora Servers :: NX And Virtual Machine Manager

Jan 22, 2010

I have an F12 installation on which I have installed NoMachine's NX server. I can remote in nicely when needed (try to do as much as possible via SSH) while not having to boot into and stay on Gnome on the server and run VNC.I noted that when I try to start the Virtual Machine Manager from an NX session, I get an error that VMM is "unable to open a connection to the libvirt management daemon". libvirtd is running, however. And, when I startx on the server and try there, VMM works fine.Is this an inherent problem with the use of VMM, or something correctable?

Fedora :: Detecting USB Devices On Virtual Machine

May 21, 2010

I am running federa 12 and just recently installed virtual Machine Manager. I've created Virtual machine and installed Windows XP on it. Everything is running OK, as far as I can see. I've installed software to manage and download pictures from Cannon camera, but I am not able to make USB port available to this Virtual machine. I tried to add hardware in VM, but not sure if I should go for STORAGE option, or PHYSICAL HOST DEVICE. I tried second option, and selected USB device. Now I've got UB hub available, but still cannot see anything attached to it (camera in my case, or USB stick with pictures).

Fedora :: Start A Virtual Machine In VirtualBox?

Jul 4, 2010

Every time I try to start a virtual machine in VirtualBox I get this error:

Code:

'/etc/init.d/vboxdrv setup' as root. Users of Ubuntu, Fedora or Mandriva should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary. So I run '/etc/init.d/vboxdrv setup' in the terminal as root and I get this:

Fedora :: Moving An LVM Based Virtual Machine

Jul 28, 2010

I'm hoping this is the right sub-forum, if not please move this post. My question is, how would I go about moving an LVM based virtual machine to a different host? Can I just use dd to copy the entire logical volume to a file, move the file to the other host, then again use dd to copy the file onto a newly created logical volume? I'm using KVM by the way.

Fedora :: Can't Create Virtual Machine With QEMU/KVM

Nov 8, 2010

I just install QEMU and virtual machine manager to use virtualization, but virt-manager cannot run properly. I can create a VM, then mount CDROM ISO, startup. With Windows installation, it runs well until format partition step, after that it is disconected and exit with error related to VNC. I dont know why have this problem cause the packages that I installed is from Fedora repo and I think they have been tested.

Here are some infos:

Fedora 14 - kernel 2.6.35.6-45.fc14.i686.PAE
qemu-2:0.13.0-0.7.rc1.fc14.i686
libvirt-0.8.3-2.fc14.i686
