build OpenShift environment within KVM

Referred to http://openshift.github.io/documentation/oo_deployment_guide_vm.html#download-vm

KVM host

[root@localhost ~]# cat /etc/fedora-release ;uname -ri Fedora release 19 (Schrödinger’s Cat) 3.10.9-200.fc19.x86_64 x86_64 [root@localhost ~]#

on KVM host, install mdns

The VM seems to use multicast DNS for name resolution.

on the KVM hsot

# yum install -y nss-mdns

edit /etc/nsswitch.conf

from

hosts:      files dns mdns4_minimal

to

hosts:      files mdns4_minimal [NOTFOUND=return] dns myhostname mdns4

convert VM image format from vmdk to row.

# qemu-img convert -O raw openshift-origin.vmdk openshift-origin.img

# mv openshift-origin.img /var/lib/libvirt/images/

register the VM via virt-manager

start the VM and access to the VM over HTTPS
