[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 10949
Summary:
Changeset 10949
- 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
