[Xen-devel] [PATCH] Fix obscure domain creation fail error

Author: Ian Jackson <ian.jackson@xxxxxxxxxxxxx>

Ian Jackson wrote this on my laptop during the hackathon to fix some
obscure error message I was getting. Note that:

1) There are other parts that do the same, so perhaps they are worth
looking at
2) The error is still quite obscure, as the actual issue was
"virtualization extension disabled" while using xen-hvm, but the errno
choosen was about "allocating memory" and libxl complains about "parsing
the config file" which are not actual problems.
