Hi,
I also dearly needed a DR feature or at least a reasonable way to hack around
it, but in this case using an actual cloud framework (Cloudstack or anything
else) seemed to make life significantly more difficult.
I am building a virt setup right now for a customer which needs DR server(s)
of
It can be fixed. I too had same issue when I did the patch on xenserver.
The problem is after you apply patch you might lost the mount point
information for example
cat /opt/cloud/bin/heartbeat
/var/run/sr-mount/42d66763-9251-ab84-8717-8f5e9dcedc09
So just simply add mount point information on /
