Re: [Xen-users] RHEL VMs in HyperV to Xen

[Edward Smith <bm.unpersonal@xxxxxxxxx>]

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

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....
