Choosing the right scheduler on a virtual maschine (kvm)

Posted on Tue 20 August 2013 in Linux • Tagged with KVM, Linux, VMware, Notepad • 1 min read

The default i/o scheduler is the Completely Fair Queuing (cfq) in the 2.6 kernel. This is not the first choice for a virtual machine/hypervisor. The combination of the noop and the deadline scheduler is much better for a virtualization host.

virtual machine: noop
hypervisor: deadline

Gentoo - Jenkins startup script

Posted on Wed 19 September 2012 in Linux • Tagged with Gentoo, linux, notepad • 1 min read

Not the best but its working for me...maybe JENKINS_* and JAVA_OPTS can be moved to /etc/conf.d/jenkins or something else.

#!/sbin/runscript

depend() {
        use logger dns
        need apache2
        provide jenkins
}

JENKINS_USER=jenkins
LOCKFILE=/var/run/jenkins.pid

Windows 7 error 0x80300001

THANKS Microsoft for this self-explanatory error message during a installation:

"Windows is unable to install to the selected location. Error: 0x80300001."

You should write "FOOOOO! Maybe you have the wrong CD/DVD in your drive."

(I had the virtio drivers cd in my drive...)

CONFIG_DEVPTS_MULTIPLE_INSTANCES
CONFIG_VETH
CONFIG_MACVLAN
CONFIG_NETFILTER_XT_TARGET_CHECKSUM
CONFIG_NETFILTER_ADVANCED
CONFIG_BRIDGE_NF_EBTABLES
