Choosing the right scheduler on a virtual maschine (kvm)

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

#!/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:

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

CONFIG_VETH
CONFIG_MACVLAN
CONFIG_NETFILTER_XT_TARGET_CHECKSUM
CONFIG_NETFILTER_ADVANCED
