Summary:
Changeset 14201
- 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)
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

Failures:
1. HVM guests fail gettimeofday02, nanosleep01/02 with
clock problems
2. 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')
3. FIXED: 32bit non-pae uniprocessor kernel guest hangs on boot
xm list shows no cpu time consumption
4. FIXED: After a guest has been up overnight, launching a 2nd
guest results in "Error: an integer is required". Destroying
the guest that had been running overnight allows the new
guest to launch fine.
File: failure.1
