Best practice for 3.1 RHEV Manager DR?
Hi,
With the exception of clustering service/HA. I am curious as to what methods other sites are leveraging to recover RHEV Manager to a new system? The recovery outline in the documents and knowledge base has not been successful for me.

More or less this is what we're doing with dd. Coupling a clone with snapshots will bypass a manual rebuild, obviously. Thought there would be a bit more insight into the restore and rebuilding process of an existing RHEV-M system to a new one. The documented process has been YMMV.
Thanks!
I do a cold image backup to a USB harddrive of the RHEV-M KVM machine. Just like the post https://access.redhat.com/node/67855, my first step in recovery is to look for a RHEL host put it on (haven't got that currently at the DR site).
Here is part of my script for doing the image backup:
echo -e "\n begin shutdown of rh6-baronne: "
/usr/bin/virsh shutdown rh6-baronne
i=0
while /usr/bin/virsh list |grep -q "rh6-baronne "
do
sleep 5
i=$i+5
echo -n "."
done
echo -n " $i seconds"
echo -e "\n verify shutdown complete: "
date
/usr/bin/virsh list
cp /etc/libvirt/qemu/rh6-baronne.xml $MAXTOR/$DIR/$SUBDIR/
cp baronne.raw $MAXTOR/$DIR/$SUBDIR/baronne.raw.${today}
sync
date
/usr/bin/virsh start rh6-baronne
