User-agent: Thunderbird 1.5.0.2 (X11/20060420)
Test Configuration:
Dell PowerEdge 430, Dual Core, 2GB, 3 SATA (Intel VT)
32bit XEN Hypervisor on a RHEL4U2 32bit root (/dev/sda)
      dom0_mem=256M (required to boot domUs)
32bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdb)
      pae=1, acpi=1, apic=1
      kernargs clock=pit
32bit fully virtualized (HVM) guest RHEL3U6 256MB (/dev/sdc)
      pae=1, acpi=1, apic=1
      kernargs clock=pit

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
