RE: [Xen-devel] Unable to bring up x86_64 UP DomU on processor #32

["Puthiyaparambil, Aravindh" <aravindh.puthiyaparambil@xxxxxxxxxx>]

The reason why this is happening is that on line 1093 in
XendDomainInfo.py, "1" is being treated as an int. My python skills are
weak. How can I cast it as a long or unsigned long? I tried using long()
and "0x1L". Both don't seem to be working.

XendDomainInfo.py: 1093     xc.domain_pincpu(self.domid, 0, 1 << cpu)

Thanks,
Aravindh
