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 XEN 64bit 2 CPU Hypervisor (booted smp): ---------------------------------------------------------------------- | XEN | Guest Kernel (SMP kernels booted with 2 CPUs) | | Changeset|-----------------------------------------------------------| | | 32bit UP | 32bit SMP | 64bit UP | 64bit SMP | | |--------------|--------------|--------------|--------------| | | Boot | Test | Boot | Test | Boot | Test | Boot | Test | |----------|------|-------|------|-------|------|-------|------|-------| | 12603 | Fail | | Fail | | Fail | | Fail | | | | (3) | | (3) | | (3) | | (3) | | |----------|------|-------|------|-------|------|-------|------|-------| | 12502 | Pass | | Pass | 851/1 | Pass | | Pass | 851/1 | | | | | | (1) | | | | (1) | |----------|------|-------|------|-------|------|-------|------|-------| | 12472 | Pass | | Pass | 850/2 | Pass | | Pass | 851/1 | | | | | | (1) | | | | (1) | |----------|------|-------|------|-------|------|-------|------|-------| | 12446 | Pass | | Pass | 850/2 | Pass | | Pass | 851/1 | | | | | | (1) | | | | (1) | |----------|------|-------|------|-------|------|-------|------|-------| | 12369 | Pass | | Pass | 850/2 | Pass | | Pass | 851/1 | | | | | | (1) | | | | (1) | ---------------------------------------------------------------------- Multiple Guest Boot Test Test is a 30 minute user load on both Guests XEN 64bit 2 CPU Hypervisor (booted smp): -------------------------------------------- | XEN | Guest Kernel | | Changeset|---------------------------------| | | 32bit 1CPU UP | 32bit 2CPU SMP | | | 64bit 1CPU UP | 64bit 2CPU SMP | | |----------------|----------------| | | Boot | Test | Boot | Test | |----------|------|---------|------|---------| | 12603 | Fail | | Fail | | | | (3) | | (3) | | |----------|------|---------|------|---------| | 12502 | Pass | Pass | Pass | Pass | | | (2) | | (2) | | |----------|------|---------|------|---------| | 12472 | Pass | Pass | Pass | Pass | | | (2) | | (2) | | |----------|------|---------|------|---------| | 12446 | Pass | Pass | Pass | Pass | | | (2) | | (2) | | |----------|------|---------|------|---------| | 12369 | Pass | Pass | Pass | Pass | | | (2) | | (2) | | -------------------------------------------- Failures: 1.
