           Summary: Memory ballooning is broken under PAE
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: jyoung5@xxxxxxxxxx


I have a dual Opteron (IBM intellistation) with 6gigs ram. When running PAE
enabled Xen ballooning memory will crash the entire system. Xm does not current
support ballooning under PAE, but you can do it from the command line. Here I am
trying to balloon dom0 down to 512mb:
