Accessing VNC Consoles

All the vm consoles on xenserver are per default only accessible via the http(s) interface, but with some few tricks you can access them directly:

All commands are done via SSH on xenserver

Warning - this bypasses a lot of xenservers security measures

Allow VNC ports through firewall
1. Append following line to /etc/rc.local
2. iptables --insert INPUT -p tcp --dport 5900:5999 -j ACCEPT
Set vncterm to listen on all interfaces instread of 127.0.0.1
1. Edit /opt/xensource/libexec/vncterm-wrapper
2. Alter the VNCTERM_LISTEN variable to "-v 0.0.0.0:1"

Autostart of VM's

The free xenserver doesn't allow to set a vm to autostart via xencenter, but there's a work-around that issue:

edit /etc/rc.local
add a line with "sleep 45" - to allow all the xen components to complete initialization (on more powerfull hardware the delay can be less than 45 seconds)
add a line with xe vm-start vm=<vm-name> for each vm you want to auto start

Download Xencenter from 6.0 550
Install wine > 1.2 (apt-get install wine1.3 or what ever you got)
Download winetricks: wget http://winetricks.org/winetricks
Use winetricks to install .net: sh winetricks dotnet2 ~~Use winetricks to install mono: sh winetricsk mono210~~
Install XenCenter from msi: wine start XenServer-6.0.0-XenCenter.msi
use wine to launch mono and xencenter: wine "C:\\Program Files\\Mono-2.10.6\\bin\\mono.exe" "c:\\XenCenter\\XenCenterMain.exe"

Enable standard repos in /etc/yum.repos.d/Centos-Base.repo (set enaboled=1)

list installed packages: rpm -qa (filter with grep)
search packages: yum search
install packages: yum install
apache package is called httpd
- make sure that it starts automatically (/etc/rc3.d)
- xapi uses port 80 so run apache from eg port 88 or 8080
