[Libvir] [PATCH] Guard a negative value of "virsh setmem" and "virsh setmexmem"

[Masayuki Sunou]

Hi

"virsh setmem" and "virsh setmexmem" have the problem of setting a very
big value in the domain when -1 is set in the domain. 

As a result, I detected the problem of doing abnormal operation of Xen
in 64bit machine. (virsh setmem)

Therefore, I contribute the patch that corrects the argument of the
function to guard a negative value. 

This treatment is based on setMemoryTarget at XendDomainInfo.py.

Thanks,
