Netbsd guest eucalyptus

Recently I was assigned a task to make NetBSD
as a Guest to run in Eucalyptus.

By default, Eucalyptus does not supports NetBSD Guest.
The reason behind is that Eucalyptus considers a Linux guest to
be splitted into 3 parts
1 . Root File System
2.  Kernel
3.  RamDisk

Some where I studied that, NetBSD  does not have RamDisk.

So here we are required to do a tweaking.

I found the following link to be very useful build a NETBSD File System,and NetBSD Kernel.


http://wiki.netbsd.org/amazon_ec2/build_your_own_ami/

By following these steps, you could build NETBSD File System,and NetBSD Kernel from Source.This will take nearly 2 - 3 Hours

We solved 2 issues by applying some patches.
This I shall write in my next post.

Now once a Kernel and File System is built for NetBSD,
upload and register
NETBSD Kernel as EKI
NETBSD Kernel as ERI
NETBSD FileSystem as EMI

That 's it !!!
