[Xen-API] blktap2 xcp

[Donald van der Wurf <d.vander.wurf@xxxxxxxxx>]

Goal: trying to get xencenter running to manage my vm's.

- ubuntu 12.04

- custom  kernel 3.4.9 built from sources. (folllowing this guide: http://wiki.xen.org/wiki/Comprehensive_Xen_Debian_Wheezy_PCI_Passthrough_Tutorial#Compiling_a_Custom_Linux_Kernel)

- after that I installed xcp and changed default  toolstack (xapi) has  been selected, and works.

now when i start a vm (from xe command, or xencenter the VM won't start. 

root@ubuntu:~/src/linux/linux-3.2.32# xe vm-start vm=windows

There was an SR backend failure.

status: non-zero exit

    raise Exception, "blktap kernel module not installed: try 'modprobe blktap'"

Exception: blktap kernel module not installed: try 'modprobe blktap'

next i tried: 

modprobe blktap2

FATAL: Module blktap2 not found

modprobe blktap

FATAL: Module blktap not found.

So, where can i get the kernel module from? i installed the following on my system, but no luck until now. Searched a lot on the Internet, but no luck...

Any ideas?
