Re: [Xen-users] nOOb to convert vmware guest to xen??

["Brian" <brian@xxxxxxxxxx>]

Had the vmware guest split into 2G chunks, converted to single growable,
verified bootable and network connectivity under VMWare. This is a good
vmdk. Here is the /etc/fstab of the VM:

/dev/sda1       /               ext3    errors=remount-ro 0       1
/dev/sda5       none            swap    sw                0       0

Next:
vmware-vdiskmanager -r vmware_image.vmdk -t 0 temporary_image.vmdk (doubt
this really needed to be done as I already converted to single growable)
qemu-img convert -f vmdk temporary_image.vmdk -O raw xen_compatible.img

Copied a swap.img from another xen vm to /var/xen/domains/xen_compat/.

/etc/xen/xen_compat.cfg:

root        = '/dev/xvda2 ro'
disk        = [
                'file:/var/xen/domains/xen_compat/swap.img,sda1,w',
                'file:/var/xen/domains/xen_compat/xen_compatible.img,sda5,w'
              ]

also tried (copied from a working xen vm)

root        = '/dev/xvda2 ro'
disk        = [
                'file:/var/xen/domains/xen_compat/swap.img,xvda1,w',
                'file:/var/xen/domains/xen_compat/xen_compatible.img,xvda2,w'
              ]

xm create -c xen_compat.cfg results:

Begin: Waiting for root file system ...

Have no idea how to pass single to a non-bootable xen VM.

Where does "mount -o remount,rw /" go, surely not in a non-bootable VM
/etc/fstab?

"edit /etc/fstab sdb to hda or whatever as in xen.cfg." I created my
xen_compat.cfg by hand, no instructions for migrated VMs.

Thanks again for any insight.
