Summary:
Changeset 13899
- gettimeofday02 nanosleep01/02 ltp tests fail (failure.1)
- 32bit non-pae uniprocessor kernel guest hangs on boot.
xm list shows no cpu time consumption (failure.3)
- 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. (failure.4)
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. BUG 666: 32bit 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. 32bit non-pae uniprocessor kernel guest hangs on boot
xm list shows no cpu time consumption
4. 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.
