[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 11690

Summary:
Changeset 11690
- XEN crash running ltp "mtest01 -p80" on 32bit SMP HVM guest:
  BUG at multi.c:2967 from sh_page_fault__shadow_3_guest_3 (failure.3)

Test Configuration:
Dell Precision WorkStation 380, Dual Core, 2GB, 3 SATA (Intel VT)
64bit XEN RELEASE Build Hypervisor on a RHEL4U2 64bit root (/dev/sda)
32bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdb)
      pae=1(smp) pae=0(up), acpi=1, apic=1
      kernargs noapic
64bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdc)
      pae=1, acpi=1, apic=1
      kernargs noapic

Boot Tests:
Boot a fully virtualized (HVM) guest to the login prompt
Results are marked Pass|Fail where (n) points to a failure description

Regression Tests:
852 tests (851 ltp tests and one 30 minute user load test)
Tests are marked #Pass/#Fail where (n) points to a failure description

Failures:
 1. BUG 666: 32bit guests fail ltp gettimeofday02
    and nanosleep01/02 with clock problems
 2. NOT REPRODUCED: XEN crash on an xm destroy of a dead guest
    32bit SMP HVM guest:
    Fatal page fault - put_page_from_l1e+0x85/0x140
 3. XEN crash running ltp "mtest01 -p80" on 32bit SMP HVM guest:
    BUG at multi.c:2967 from sh_page_fault__shadow_3_guest_3
 4. XEN crash running ltp "mtest01 -p80" on 32bit SMP HVM guest:
    BUG at multi.c:4082 from sh_clear_shadow_entry__shadow_3_guest_3
 5. FIXED: 64bit UP and SMP guests crash domain on boot
    domain_crash_sync called from vmx.c:2268
 6. FIXED: 32bit SMP HVM Guests hang on boot:
    "Uncompressing Linux... OK booting the kernel"
 7. FIXED: 64bit UP/SMP HVM Guests hang on boot:
    "Decompressing Linux... done booting the kernel"
 8. Domain crash running ltp "mtest01 -p80" on 32bit SMP
    HVM guest and then XEN locked up requiring a hard reset:
    domain_crash_sync called from private.h:495
