192.168.253.11: /* Images umwandeln */

=Installation=
==Vorbereitung==
Testen ob VT Unterstützung der CPU vorhanden ist
egrep -c '(vmx|svm)' /proc/cpuinfo
0 bedeutet keine Unterstützung
1 (oder mehr) Unterstützung vorhanden
==Basis Pakete==
apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils virtinst
apt-get install ssh-askpass

==Verifizieren der Installation==
virsh -c qemu:///system list
Id Name Status
----------------------------------
==Installation des Virtmanagers(GUI)==
apt-get install virt-manager
==Installation des Linux capabilities tools==
apt-get install libcap2-bin
==Vergeben der CAP_NET_ADMIN Fähigkeit==
setcap cap_net_admin=ei /usr/bin/qemu-system-x86_64
setcap cap_net_admin=ei /usr/bin/qemu-system-i386

==Erlauben der Beerchtigung für den Adminuser==
echo cap_net_admin xinux >> /etc/security/capability.conf

==Netzwerk mit Bridgefunktion==
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet manual

auto br0
iface br0 inet static
address 192.168.240.101
netmask 255.255.240.0
gateway 192.168.240.100
bridge_ports eth0
bridge_stp off
bridge_fd 1
bridge_maxwait 12

Damit libvirt-bin automatisch start muss man in der Datei /etc/default/libvirt-bin die Option start_libvirtd auf "yes" setzen.
vi /etc/default/libvirt-bin
start_libvirtd="yes"

=Domain-Installation=

virt-install --connect qemu:///system --name orion --ram 1024 --disk path=/dev/data/orion \
--cdrom /isos/ubuntu-10.04-server-amd64.iso --vnc --noautoconsole --os-type linux --accelerate --network=bridge:br0

=Handling=
This command outputs the guest's XML configuration file to standard out (stdout).
You can save the data by piping the output to a file. An example of piping the output to a file called guest.xml:

virsh dumpxml GuestID > guest.xml

= Migration zu neuem Host =
virsh migrate --live <GuestName> <DestinationURL>

Beispiel:
# virsh migrate --live galactica qemu+ssh://test2.example.com/system

=Autostart =
virsh atutostart <domain>
virsh atutostart <domain> --disable
=An/Aus=
Connecten auf Hypervisor
virsh -c qemu+ssh://''SERVER''/system
In Konsole eingeben

Zum starten:
start ''VM''
Zum virtuellen Stecker rausziehn:
destroy ''VM''
Nach Installation von '''acpid''' auf ''VM''

Normales herunterfahren:
shutdown ''VM''

=Configure a Serial Console in the Guest=
==Enable on the VM==

cat /etc/init/ttyS0.conf

# ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec /sbin/getty -L 115200 ttyS0 xterm

Run the following command to initiate the Serial Console (or restart the VM):

sudo start ttyS0

==Connect on Host to VM==

console VM
00:50:56:00:31:f9

=Virtuelle MACAdresse vergeben=

gaius=KVM server

virsh console XXXXXXX
VM: cp /etc/udev/rules./70-persistent.net(cd).rules 70-persistent.net(cd).rules.orig
VM: herunterfahren...
gaius: vi /etc/libvirt/qemu/XXXXXX.xml

-> MAC eintragen

gaius: virsh define XXXXXXXX
gaius: virsh start XXXXXXXX

Damit libvirt-bin automatisch start muss man in der Datei /etc/default/libvirt-bin die Option start_libvirtd auf "yes" setzen.
vi /etc/default/libvirt-bin
start_libvirtd="yes"

=Domain-Installation=

virt-install --connect qemu:///system --name orion --ram 1024 --disk path=/dev/data/orion \
--cdrom /isos/ubuntu-10.04-server-amd64.iso --vnc --noautoconsole --os-type linux --accelerate --network=bridge:br0

--name Name der Domain

--disk Diese Images werden in die Domain eingebunden. Es können mehrere Disks eingebunden werden, sowie weitere Optionen getrennt mit Leerzeichen gemacht werden.

--ram Zu Verfügung stehender Arbeitspeicher der Domain

--os-type linux, windows, solaris etc.

--os-variant ubuntukarmic, winxp etc.

--hvm Gebraucht full virtualization.

--accelearte Benutze kvm oder KQEMU, wenn vorhanden.

--import Die Installation ist bereits im Disk-Image enthalten.

--vnc Aktiviert VNC-Display und öffnete einen beliebigen Port >5000, falls nicht --vncport angegeben ist.

--vncport Setzt den Port für VNC fest.

192.168.253.11: /* Links */

=Installation=
==[ALL] Initial setup==
Install required packages:
sudo apt-get install pacemaker cman resource-agents fence-agents gfs2-utils gfs2-cluster ocfs2-tools-cman openais drbd8-utils
Make sure each host can resolve all other hosts. Best way to achive this is by adding their IPs and hostnames to /etc/hosts on all nodes. In this example, that would be:

eth0
192.168.244.161 fix
192.168.244.162 foxy
eth1
10.168.244.161 fix-ha
10.168.244.162 foxy-ha

Disable o2cb from starting:

update-rc.d -f o2cb remove

==[ALL] Create /etc/cluster/cluster.conf==
Paste this into /etc/cluster/cluster.conf:

<?xml version="1.0"?>
<cluster config_version="1" name="pacemaker">
<cman two_node="1" expected_votes="1"> </cman>
<fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/>
<clusternodes>
<clusternode name="fix" nodeid="1" votes="1">
<fence>
<method name="pcmk-redirect">
<device name="pcmk" port="fix"/>
</method>
</fence>
</clusternode>
<clusternode name="foxy" nodeid="2" votes="1">
<fence>
<method name="pcmk-redirect">
<device name="pcmk" port="foxy"/>
</method>
</fence>
</clusternode>
</clusternodes>
<fencedevices>
<fencedevice name="pcmk" agent="fence_pcmk"/>
</fencedevices>
</cluster>

Validate the config
# ccs_config_validate
Configuration validates

==[ALL] Edit /etc/corosync/corosync.conf==

Find pacemaker service in /etc/corosync/corosync.conf and bump version to 1:

service {
# Load the Pacemaker Cluster Resource Manager
ver: 1
name: pacemaker
}

Replace bindnetaddr with the IP of your network. For example:

bindnetaddr: 10.168.244.0

'0' is not a typo.

==[ALL] Enable pacemaker init scripts==

update-rc.d -f pacemaker remove
update-rc.d pacemaker start 50 1 2 3 4 5 . stop 01 0 6 .
==[ALL] Start cman service and then pacemaker service==
deactivat quorum
# echo CMAN_QUORUM_TIMEOUT=0 >> /etc/default/cman

# service cman start

==[ALL] Enable pacemaker init scripts==

update-rc.d -f pacemaker remove
update-rc.d pacemaker start 50 1 2 3 4 5 . stop 01 0 6 .

service pacemaker start
Starting Pacemaker Cluster Manager: [ OK ]

==[ONE] Setup resources==
Wait for a minute until pacemaker declares all nodes online:

==[ALL] Initial setup==
Install required packages:
sudo apt-get install pacemaker cman resource-agents fence-agents gfs2-utils gfs2-cluster ocfs2-tools-cman openais drbd8-utils
Make sure each host can resolve all other hosts. Best way to achive this is by adding their IPs and hostnames to /etc/hosts on all nodes. In this example, that would be:

eth0
192.168.244.161 fix
192.168.244.162 foxy
eth1
10.168.244.161 fix-ha

==[ALL] Initial setup==
Install required packages:
sudo apt-get install pacemaker cman resource-agents fence-agents gfs2-utils gfs2-cluster ocfs2-tools-cman openais drbd8-utils
Make sure each host can resolve all other hosts. Best way to achive this is by adding their IPs and hostnames to /etc/hosts on all nodes. In this example, that would be:

eth0
192.168.244.161 fix
192.168.244.162 foxy
eth1
10.168.244.161 fix-ha
10.168.244.162 foxy-ha

Disable o2cb from starting:

update-rc.d -f o2cb remove

==[ALL] Create /etc/cluster/cluster.conf==
Paste this into /etc/cluster/cluster.conf:

<?xml version="1.0"?>

Find pacemaker service in /etc/corosync/corosync.conf and bump version to 1:

}

Replace bindnetaddr with the IP of your network. For example:
