           Summary: most of qcow images cannot boot since c/s 16958
           Product: Xen
           Version: unstable
          Platform: Other
        OS/Version: Windows
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Tools
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: haicheng.li@xxxxxxxxx


We found since c/s 16958, most of our qcow images will hang on boot; xm
dmesg shows:
(XEN) HVM3: int13_harddisk: function 41, unmapped device for ELDL=81
(XEN) HVM3: int13_harddisk: function 08, unmapped device for ELDL=81
(XEN) HVM3: *** int 15h function AX=00C0, BX=0000 not yet supported!

When this hang happens, "xm destroy" command cannot destroy that domain
any more; and xend will lose response after running "xm destroy" until
this qemu process is killed by "kill -9".

This issue blocks our testing. And c/s 16945 has no such issue. 

Detailed xm dmesg log is attached.
