[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 10899

[Ed Smith <esmith@xxxxxxxxxxxxxxx>]

Summary:
Changeset 10899
- 32bit and 64bit SMP and UP HVM guests boot cleanly with a
  working guest network.  Regression testing is again possible.

Test Configuration:
Dell Precision WorkStation 380, Dual Core, 2GB, 3 SATA (Intel VT)
64bit XEN 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:
    "Time is going backwards"
 2. Multiple HVM guests (32/64 SMP) crash under load:
    32bit SMP guests fail ltp mtest01w:
    "Couldn't alloc shadow page!"
    "domain_crash_sync called from shadow.c:445 "
