[Xen-users] How to convert windows 2003 from XenServer to Xen

[Adam Goryachev <mailinglists@xxxxxxxxxxxxxxxxxxxxxx>]

I'm having some trouble converting a MS Windows 2003 server from
XenServer 5.6 to Xen.

What I've done:
1) Export of the VM from XenCenter and saved to a file
2) Converted the tar file, and re-built a raw image file
3) Wrote the final file to a LVM, fdisk -l <LVM> shows the partition table
4) Exported the LVM via iSCSI, the remote physical machine can see the
partition table on the iSCSI device
5) Started the VM

What I get:
Normal boot up process, except when doing a normal boot, I get stuck
with the black screen, windows logo, and the moving blue bar across the
bottom. This continues for more than 6 hours.... ie, it hangs, though
the blue bar is still moving.

I've copied this config from another machine which is running a windows
2003 VM successfully....

Just realised, this seems to repeat approx once per minute.

I can boot into "safe mode" and get a working system, but obviously I
need to be able to boot normally...

If any additional information needs to be provided, please let me know.

Can anybody suggest a solution to make this work?
PS, yes, I made an iso image of all the GPLPV drivers (current version)
so that once the machine boots I can install them, but I don't seem to
get far enough to install them....

Regards,
Adam
