Scripted way for installing a virtual XenServer/XCP hypervisor.

Requirements:

• 64 bit machine, 64 bit operating system (tested on Ubuntu 12.04)
• XCP/XenServer or KVM or VirtualBox
• Ubuntu packages: p7zip-full genisoimage fakeroot fuseiso

You can download manually the latest xcp distribution, or you could use the script provided to download XCP 1.6 :

./scripts/download_hypervisor_iso.sh

If you would like to use a XenServer, please download the iso manually.

The answerfile could be generated to the standard output, by:

./scripts/generate_answerfile.sh dhcp > answers

This example should work with KVM

./scripts/generate_answerfile.sh static -h myvirtserv -i 10.0.2.69 -m 255.255.255.0 -g 10.0.2.2 > answers

Please run scripts/generate_answerfile.sh to see the various options available.

Remaster a XenServer/XCP iso, so that it installs automatically. Specify the downloaded iso file, the target iso, and the answerfile

./scripts/create_customxs_iso.sh hypervisor.iso customxs.iso answers

Given, your network's name is net and your xenserver host is xshost.somedomain, and you want to give the name VMH1 to your new virtual hypervisor, you should type:

scripts/xs_start_create_vm_with_cdrom.sh customxs.iso xshost.somedomain net VMH1

After this, you'll have a virtual hypervisor installed with the name VMH1.

There are simple scripts, which assume, you have customxs.iso in your working directory, and use that to install a hypervisor.

To create a new VM with the remastered iso, all you have to do, is to run:

./create_virtual_hypervisor.sh

This installs the hypervisor on KVM. Should you wish to use VirtualBox, specify the virtualbox option:

./create_virtual_hypervisor.sh virtualbox

As the script is finished, you should have a vm, with the hypervisor installed inside. To start the vm, for the kvm case, you should type:

./scripts/kvm_start_vm.sh

In the VirtualBox case, go to the UI, and start the VM there. In both cases the ssh port of the VM is forwarded to the host's 2222 port.

The virtual hypervisor's ssh port is forwarded to your localhost's 2222 port.

ssh -p 2222 root@localhost

The password for the root user could be found in the generated answerfile. It could be set with via commandline options. The default password is:

somepass

Run:

./teardown.sh

This will remove the VM, and the generated iso.

You need to use raring, due to these bugs:
