Hi,

When I tested xm create command, I saw the following error message. I expected an error message "Error: (12, 'Cannot allocate memory')" because I intentionally caused a memory shortage on the test. But the error message was different from my expectation.

# xm create /xen/HVMdomain.1 Using config file "/xen/HVMdomain.1". Error: an integer is required

I looked at xend.log to examine the cause why the error message was shown. (Could you see the attached xend.log?) xend had the error message "Error: (12, 'Cannot allocate memory')" first. But xend changed the error message to "Error: an integer is required" halfway. I'm not sure about the cause why an exception occurred in logging processing. But when I applied an attached patch, I confirmed that the error message that I expected was shown. The patch does not call xc.domain_destroy_hook() if self.domid is None.

Could you comment on the patch? I'd like to solve the problem because I think that users want correct error message.
