Summary: Changeset 10960 - 32bit and 64bit SMP and UP HVM guests boot cleanly and pass most Regression tests - Running a 32bit and 64bit guest together crash with a "Couldn't alloc shadow page!" under load. Test Configuration: Dell Precision WorkStation 380, Dual Core, 2GB, 3 SATA (Intel VT) 64bit XEN 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 kernargs noapic 64bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdc) pae=1, acpi=1, apic=1 kernargs noapic 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 | |----------|------|-------|------|-------|------|-------|------|-------| | 10960 | Pass | | Pass | 846/6 | Pass | | Pass | 852/0 | | | | | | (1,2) | | | | | |----------|------|-------|------|-------|------|-------|------|-------| | 10949 | Pass | | Pass | 846/6 | Pass | | Pass | 851/1 | | | | | | (1,2) | | | | (1) | |----------|------|-------|------|-------|------|-------|------|-------| | 10925 | Pass | | Pass | 846/6 | Pass | | Pass | 852/0 | | | | | | (1,2) | | | | | |----------|------|-------|------|-------|------|-------|------|-------| | 10910 | Pass | | Pass | 846/6 | Pass | | Pass | 852/0 | | | | | | (1,2) | | | | | |----------|------|-------|------|-------|------|-------|------|-------| | 10899 | Pass | | Pass | 726/4 | Pass | | Pass | 852/0 | | | | | | (1,2*)| | | | | ---------------------------------------------------------------------- * Test run did not complete because failure.2 locked up the node.
