Summary:
Changeset 11760
- Several ltp clock 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)
- The ltp "mtest01 -p80" crashes XEN:
Error: shadow lock held by shadow_update_cr3 (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)

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
