[Xen-devel] using 3.1.2 c/s 15490, xend hangs when attempt to start domain with more memory than available

["Krysan, Susan" <KRYSANS@xxxxxxxxxx>]

Using 3.1.2 c/s 15492 on Unisys ES7000 configured with 32 processors and 128 gb memory, I attempted to start a 160 gb domU.  The xm create command hangs, as well as any other xm commands that are issued.  If I do ctl-c of the hanging xm create command, I am able to terminate it and then xm commands are once again functional.

 

I expected to get an error that there was not enough memory available to start the domain. 

 

Xend.log shows:
