Yes, there are at least two issues in ocf:heartbeat:VirtualDomain:

1/ dealing with user input derived value, in an unchecked manner, while
   such value can be an empty string or may contain spaces
   (for the latter, see also I've raised back then:

2/ agent doesn't try to figure out whether is tries to parse
   a reasonably familiar file, in this case, it means it can
   be grep'ing file spanning up to terabytes of data

In your case, you mistakenly pointed the agent (via "config" parameter
as highlighted above) not to the expected configuration, but rather to
the disk image itself -- that's not how talk to libvirt -- only such
a guest configuration XML shall point to where the disk image itself
is located instead.  See ocf_heartbeat_VirtualDomain(7) or the output
you get when invoking the agent with "meta-data" argument.

Such configuration issue could be indicated reliably with "validate-all"
passed as an action for configured set of agent parameters would
1/ and/or 2/ not exist in the agent's implementation.
Please, file issues against VirtualDomain agent to that effect at

In addition, there may be some other configuration discrepancies as
pointed out by Ken.  Let us know if any issues persist once all these
are resolved.
