Hi All,

I need help for creating private file system for Guest OS: XenU

I had successfully booted my host OS with Xen0 which is running linux2.6.18 version and is using the physical device /dev/hda1.

Now my next step is to boot the guest OS and for that I first need to create the private file system for this guest OS. As you mentioned there could be 3 methods to create a private file system:
* File Based image
* LVM Based
* Physical Partition

Now as per my understanding, File Based Image is easy to create but has some poor I/O performance and from I/O performance perspective, Physical Partition is better. My requirement for installing Xen is to do some OS profiling on Guest OS, so that way it seems Physical Partition could be right choice for me.

Could you please let me know the step-by-step approach to set up Physical partiton for booting XenU. Also let me know the changes I need to make for my config file for booting XenU-(Guest OS).

Also, if possible let me know for file based image so that I can have one different domain running on File Based image(File system) and can try profiling on this also.

My available drives are /dex/hda2 /dev/sda1 /dev/sda2 /dev/sdb1 /dev/sdb2
I like using LVM, because I can more gracefully resize or snapshot the partitions and work with the snapshot, rather than the original partition, for backup purposes. It's performance is similar if not identical to that of a physical partition.

Are you comfortable working with fdisk to create partitions? And what does your partitioning look like right now? If all your extra disk is already in LVM "physical volumes" and "group volumes", it'll be simpler to create a new "logical volume" with the command 'lvcreate'.

You've also failed to say what OS your Dom0 is, which affects the tools available for building your DomU, and whether you want full virtualization or para-virtualization. It makes a difference!
