Summary:
Changeset 12621
- NEW: RHEL4U2-64bit uniprocessor kernel guest panics on boot:
Kernel panic from APIC_init_uniprocessor+133 (failure.4)
- nanosleep01/02 tests run much better, taking many passes before
failing. The gettimeofday02 ltp clock test still fails (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. BUG 666: 32bit guests fail ltp gettimeofday02
and 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 and 64bit HVM domains crash on boot
(XEN) a6, This opcode isn't handled yet!
4. 64bit uni-processor guest doesn't boot:
