[one-users] Experiments with haizea and OpenNebula

[davood ghatreh]

Hi Paulo,

Here it is. Just please note it is not a copy paste procedure, and you need
to know what you are doing.
It is divided to two steps. One for Oned server, one for virtulalization
server(s). I used CentOS6 65 on all servers, and virtualization layer is
KVM.

for oned server (OpenNebula):

   25  cd /home/
rpm -ivh
http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
   48  yum install wget sqlite bridge-utils tunctl gcc python-devel scons
ruby-devel rubygems redhat-lsb
   75  wget
http://dev.opennebula.org/packages/opennebula-3.0.0/CentOS-6.0/opennebula-3.0.0-1.x86_64.rpm
   78  yum localinstall install opennebula-3.0.0-1.x86_64.rpm --nogpgcheck
   76  /usr/share/one/install_gems
  77  /usr/share/one/install_novnc.sh
   18  vi /etc/one/sunstone-server.conf and change host and check auth to
be base

   18  su oneadmin

*(REFRENCE1)*id oneadmin ==> create the same user with the same gid and uid
in MTSes (virtualization servers)

   19  mkdir ~/.one
   20  echo "oneadmin:*password*" > ~/.one/one_auth
   21  chmod 600 ~/.one/one_auth
   22  one start
   19  oneacctd start
   20  sunstone-server start
   23  to check if it is up run: onevm list

ssh-keygen
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ chmod 700 ~/.ssh/
$ chmod 600 ~/.ssh/id_dsa.pub
$ chmod 600 ~/.ssh/id_dsa
$ chmod 600 ~/.ssh/authorized_keys

to run the shared storage on NFS:
echo "/var/lib/one/ *MTSserverNames*(rw,no_root_squash)" >> /etc/export

service nfsrestart
service nfslock restart
service portmap restart
chkconfig --level 35 portmap on
chkconfig --level 35 nfslock on
chkconfig --level 35 nfs on

======================================
Now to make MTSes ready to be added in opennebula:

echo "*sharedstorageservername*:/var/lib/one/ /var/lib/one/" >>
/etc/rc.local
mount *sharedstorageservername*:/var/lib/one/ /var/lib/one/
rpm -ivh
http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
yum install bridge-utils tunctl ruby

find *XXXX *using *REFRENCE1* in Oned server and then run following in
MTSes:

groupadd --gid *XXXX* oneadmin
useradd --uid *XXXX* -g oneadmin -d /var/lib/one oneadmin
usermod --groups oneadmin,kvm,qemu oneadmin

Modify /etc/libvirt/qemu.conf to include dynamic_ownership = 0 and make
following changes:
user = "oneadmin"
group = "oneadmin"

open /etc/libvirt/libvirtd.conf and make sure following are uncommented

listen_tcp = 1
unix_sock_group = "oneadmin"
unix_sock_ro_perms = "0777"
unix_sock_rw_perms = "0777"



then create:

/etc/polkit-1/localauthority/50-local.d/50-org.example-libvirt-remote-access.pkla

[org.libvirt.unix.manage]
Identity=unix-user:*
Action=org.libvirt.unix.manage
ResultAny=yes
ResultInactive=yes
ResultActive=yes

service libvirtd restart

chmod 700 /etc/sudoers
edit /etc/sudoers and add:

oneadmin    ALL=(ALL)       NOPASSWD: ALL

then comment:
Defaults    requiretty


chmod 440 /etc/sudoers



and at last:

ln -sf /usr/libexec/qemu-kvm /usr/bin/kvm


reboot all servers and login to sunstone and add your MTSes. Keep in mind
that you need to run oned *just *as oeadmin user.

everyone is welcomed to change and improve these steps,


Thanks
Davood
