Out of memory isn't the only reason the function can fail. Add a message
stating that copying of a XML node failed.
Could it still fail due to OOM as well, though? And if so, is there any
way of differentiating? (I previously looked into this for some other
libxml2 function, ended up asking DV, and I believe I was told that
there isn't any way to tell the difference, but as usual IMBES (I May Be
Experiencing Senility).
At any rate, your changed message is more correct, since it's not making
any unsubstantiated assumption about the cause of the error, while
virRemoveOOMError() was).
