x86_32 (no PAE support)   

        SLES 9 SP2 on IBM xSeries 235 (512M RAM) and FC3 on IBM
        ThinkCentre
        Builds with workaround* and boots without problems
        Able to create domU
        Ran LTP on both dom0 and domU
        No problems observed
        ISSUE: 
              * Build break on SLES 9 , Bugzilla #179
              * Missing -lcurses
              * *Workaround is to change LD_LIBS in
                tools/xenstat/xentop/Makefile to include -lncurses
                instead of -lcurses

x86_32 (PAE)

        SLES 9 SP2, FC3, and RHEL 4 IBM xSeries 305, and IBM ThinkCentre
        Dom0 boots without problems; however,
        We are able to create DomUs ONLY when using *swiotlb=force* as a
        kernel parameter for dom0
        Ran LTP on both Dom0 and DomU
        
        ISSUES:
        DomU boot crashes Dom0, Bugzilla #168 
              * Workaround: use swiotlb=force as a kernel parameter when
                booting dom0
              * DomU boots up normally if using swiotlb=forceX server
                will not come up on Dom0 on a FC3 box when Xen built
                with PAE 'on', Bugzilla #137
        Networking issue on FC3 when Xen built with PAE, Bugzilla #173
              * DomU unable to get dhcp address
              * tcpdump shows lots of networking activity being 'heard'
              * ping from external box shows corrupt packets
              * DomU has no trouble getting IP address when Xen built
                non-PAE
        X server does not come up on FC3 box with PAE support, Bugzilla
        #137
              * X server comes up normally when xen built without PAE
                support
