[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 13650



Summary:
Changeset 13650
- gettimeofday02 nanosleep01/02 ltp tests fail (failure.1)
- After a 256MB guest has been up and running for some time
  on a 2GB node, launching another 256MB guest fails with:
  Error: (12, 'Cannot allocate memory') (failure.2)
- 32bit non-pae uniprocessor kernel guest hangs on boot.
   xm list shows no cpu time consumption (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
64bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdc)
      pae=1, acpi=1, apic=1

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
