[Xen-users] how to setup a hvm using image file, which include LVM partition, as backend

["thomas fan" <thomas.hf.fan@xxxxxxxxx>]

Basically, I want to use a VMWare image in the XEN.

 

I have a RHEL43 installation using LVM at VMWare, and then I convert the .vmdk file into a raw .img file using qemu-img file, name it as rhel43-flat.img.

#fdisk -l -u rhel43-flat.img
You must set cylinders.
You can do this from the extra functions menu.

Disk rhel43-flat.img: 0 MB, 0 bytes
255 heads, 63 sectors/track, 0 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes

          Device Boot      Start         End      Blocks   Id  System
rhel43-flat.img1   *          63      208844      104391   83  Linux
rhel43-flat.img2          208845    41929649    20860402+  8e  Linux LVM
Partition 2 has different physical/logical endings:
     phys=(1023, 254, 63) logical=(2609, 254, 63)

I searched a lot, there are follwing instructions on how to setup a hvm:

# lvcreate -L 20G -n rhel43 vg
# dd if=rhel43-flat.img of=/dev/vg/rhel43 bs=1M

It uses a logical volume to finish this job, however I want to know if there is a way to setup the hvm using the file as backend instead of LVM(We can split the original image into multiple image through dd, but just not use a logical volume). Is there anybody having some ideas?

Thanks,

Thomas
