[Xen-devel] Testing status of fully virtualized guests (Intel VT) on 64bit XEN unstable

[Ed Smith <esmith@xxxxxxxxxxxxxxx>]

Summary: 64 bit guests are booting again on 2 CPU Hypervisors
         32 bit guests are NOT booting on 2 CPU Hypervisors

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, acpi=1, apic=1
      kernargs clock=pit
64bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdc)
      pae=1, acpi=1, apic=1
      kernargs clock=pit 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:
851 tests (850 ltp tests and one 30 minute user load test)
Tests are marked #Pass/#Fail where (n) points to a failure description
