Hi,
thanks for the suggestions.
To resolve part of my problem I copy the entire vhd file from the MS
HyperV to the Dom0 machine. Then I create a LV and copied the file to
the LV with the dd command. I can mount this.
My problem now is boot the machine.
I changed all the entries "/dev/hdaX" to "/dev/xvdaX" on the fstab file.
Also I changed the "root=XXX" entries on the grub, "menu.lst", and in
the config file of the VM.
But I get always the same error message:
Error: (2, 'Invalid kernel', 'xc_dom_parse_elf_kernel: ELF image has no
shstrtab\n')
I suspect this is because the kernel type.
To run RHEL guest on xen I need other kernel (a special one with xen
paravirtualization)? or I can maintain the actual.
Sorry, I'm a newbie in Xen.
I already read the:

but I need more help.
Thanks,
Edward

You can try booting the VM from an .iso live disc and using the above
trick to copy the entire FS at the block level to a premade
partition/logical volume.

Hi Thomas,
first of all I appreciate your suggestion. But I can't do this with the VMs
running on Hyper-V.
I need shutdown all VMs on the Hyper-V and them move them to the Xen
Hypervisor.
The idea is copy the vhd or convert it with something... mount this disk??
to a lvm in dom0 and boot the VMs...
Any ideas???
Or other procedures, ideas, suggestions are welcome.
Thanks,
Edward

Hello,
I have several RHEL VMs running in the MS HyperV2, but now I need move
them to Xen hypervisor.
In the MS HyperV I have a vhd for each VM.
In Xen hypervisor I want use a logical volume for each machine.
So I need to convert images?
There are any procedure that I can follow? because I'm not really
familiarized with Xen.
This will work for you....
Shutdown ALL Services in the VMs on the HyperV-Box, like mysql and
whatever because of "opened Files" which could cause a FS-Error....
All Steps below are done on the dom0....
Create a LVol on the XEN-Box
lvcreate -L 15G -n VM1-Disk $VG
Create a FS
eg.
# mkfs.ext3 /dev/$VG/VM1-Disk
Mount the LVol in Dom0
# mount /dev/$VG/VM1-Disk /mnt
Copy the entire /-FS from your Hyper-V-VM to the dom0
On the Dom0:
# rsync -avzH --numeric-ids -e ssh root@OLD-IP:/* /mnt/
Create a xen-config for your new Host and boot it up....
I appreciate any help,
Thanks,
hth,
Thomas
