Summary:
Changeset 12603
- NEW: 32bit and 64bit HVM domains crash on boot
(XEN) a6, This opcode isn't handled yet! (failure.3)
- 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
