This was a Virtual Machine creation in Xen Server with Windows 2008 Server OS - Enterprise Edition serves just fine if not going to use intensively 8 or plus CPUS, and Memory 32/64 GB

Creation

From the maretec user at the MrtXnSrv, 192.168.20.125 with putty was created a virtual machine to handle FTP site:

Mounted a ISO

First mounted the Windows OS folder from kepler (192.168.20.131) so that can be used for virtual machine OS install (Windows 2008 Server):

ex: sudo /bin/mount -t cifs -o [credentials] [Folder Origin location] [Folder Destination location]

>sudo /bin/mount -t cifs -o username=Administrator,password=XXXXX,workspace=MARETEC //192.168.20.131/Software/Windows_2008_Server_32bits 
/home/maretec/mnt/ISO

Created a new Logical Volume (LV)

It was created a LV with 200GB (50 for OS).

ex: sudo /sbin/lvcreate -n [Name of LV] -L [size of LV] [Volume group where LV will be]

>sudo /sbin/lvcreate -n vmmrtsrv08_FTP -L 200GB dados01

Created a new config file

It was created a config file based on vmmrtsrv06-1.0.cfg and adapted to ISO file and LV created.

• vmmrtsrv08_1.cfg

It was used command vi to edit the file

Created the Virtual Machine (VM) and started it

in /home/maretec/xen_configs the config file was used to create the VM

Checked port for VNC connection

>sudo /usr/sbin/xm list -l VMMRTSRV08_FTP
see in location localhost: 5904

Configuration

In the VM first was installed the OS and then configured.

Accessed the domain via a console with VNC

Access the domain with a VNC client, such as <goto>TightVNC</goto>. The domain console access port with VNC is 192.168.20.125:5904.

OS Installation - in the console

See instructions in How to Install Windows on a new machine These steps include windows updates, antivirus installation, format of non system partition, enable remote desktop.

Attention Windows 2008 Server Enterprise Edition serves just fine if not going to use intensively 8 or plus CPUS, and Memory 32/64 GB

Attention Do not create partitions in windows installation. Check how to do this with logical volumes (2 one for system and one for work) it will facilitate migration.

Attention - do not add the machine to the MARETEC domain!!! As this machine was to be in the DMZ, adding to the maretec domain may cause problems to the domain administrator This was made in the installation and caused some problems.

OS Update with drivers

Mail from Marco Reis

Actualizei múltiplos drivers do sistema VMMRTSRV08_FTP, fazendo uso do VMDP (Virtual Machine Driver Pack) específico para o Windows 2008 32bits, e que já havia oportunamente  instalado no host Xen (portanto o dom0, ou seja o MRTSRV01).

Uma listagem dos pacotes (rpm) relevantes:
mrtsrv01:~ # rpm -qa | grep -i vmdp
vmdp-1.2.0-4
vmdp-xen-rhel5-1.2.0-4
vmdp-xen-winxp-1.2.0-4
vmdp-xen-rhel4-1.2.0-4
vmdp-xen-win2000-1.2.0-4
vmdp-xen-win2008-1.2.0-4
vmdp-xen-winvista-1.2.0-4
vmdp-xen-win2003-1.2.0-4
mrtsrv01:~ # 

Para obter a path específica do ISO relevante para o sistema em causa:
mrtsrv01:~ # rpm -ql vmdp-xen-win2008-1.2.0-4 /opt/novell/vm-driver-pack/xen/vmdp-xen-Win2008-32bit-drivers.iso
/opt/novell/vm-driver-pack/xen/vmdp-xen-Win2008-64bit-drivers.iso
mrtsrv01:~ # 

O ISO em questão está aliás agora montado na drive de CD-ROM do VMMRTSRV08_FTP.
Para mudarem para outro ISO basta fazer um comando do tipo:
> xm block-configure VMMRTSRV08_FTP file:/caminho/para/ficheiro.iso 
> hdc:cdrom r

Claro está que (isto na visão retorcida da Microsoft) a instalação de novos drivers para o interface de rede implicou a criação de um novo (que designei por
DMZ): foi assim necessário fazer a reconfiguração desse através de VNC.

IP changed - in the console

Attention this step was not necessary because the machine was to be added to the DMZ

IP changed to fixed IP: IP:192.168.20.40

SubNet Mask  : 255.255.255.0

Default Gateway  : 192.168.20.1

Preferred DNS Server: 192.168.20.1

Attention this step was not necessary because the machine was to be added to the DMZ

Changed the bridging between the LAN and the DMZ

Switching from LAN(eth0) to DMZ(eth1) - in the Xen Server

> sudo /usr/sbin/xm shutdown VMMRTSRV08_FTP                                                            (shutdown machine - appears in xm list)
> sudo /usr/sbin/xm list -l VMMRTSRV08_FTP > xen_configs/VMMRTSRV08_1.cfg                              (see actual config)
> sudo /usr/sbin/xm delete VMMRTSRV08_FTP                                                              (delete machine - does not appear in xm list)
> cp xen_configs/VMMRTSRV08_1.cfg xen_configs/VMMRTSRV08_2.cfg                                         (create new config - 2)
> vim xen_configs/VMMRTSRV08_2.cfg                                                                     (start edit config - 2)
08_2.cfg> (bridge eth1) [click insert twice to replace 0 with 1]
08_2.cfg> :w (to write file)
08_2.cfg> ZZ (to save and exit)
> cd /xen_configs                                                                                      (go to config dir)
> sudo /usr/sbin/xm new -F VMMRTSRV08_2.cfg                                                            (create new machine)
> sudo /usr/sbin/xm start VMMRTSRV08_FTP                                                               (start new machine)

IP change - in the console

Then, use TighVNC to enter the domain through console access as ???user???:

• Network And Sharing Center--> Local Area Connection (view status) --> Properties --> TCP/IPv4
• Static ip-->192.168.21.30
• Subnet mask-->255.255.255.0
• Gateway--> 192.168.21.1
• Save.

Allow Remote Desktop in FireWall Settings

Open Ports

Finally, you need to ask Marco Reis from Conexa to configure the router firewall so it links the ports between the LAN firewall and the DMZ firewall (reverse tunneling, height port). You might as well ask also to open up ports 21, 20, 80, 443 and 8080.

FTP configuration

Marco said there are bether tools, in what concerns performance, security, versality than IIS. Ask examples.

Do a Snapshot of the VM

Created a snapshot in 18-01-2009

ex: sudo /sbin/lvcreate -n [Name of the snapshot] -s [path to LV that will be snapshoted] -L [snapshot size]

>sudo /sbin/lvcreate -n VMMRTSRV08_FTP_SNAP20100118 -s /dev/dados01/vmmrtsrv08_FTP -L 200G

Question: Need to do this process again? Or the exception table will keep all the block changes now on?
