[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 11414
Summary:
Changeset 11414
- XEN panic booting an 64bit SMP HVM guest with/without noapic.
32bit SMP HVM guests get the same error and then boot up OK
but with only one of their two CPUs.
(failure.3 (XEN) malloc vlapic regs error for vcpu 1)
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

Failures:
1. BUG 666: 32bit guests fail ltp gettimeofday02:
"Time is going backwards"
2. FIXED: HVM guests fail to boot:
Error: (12, ''Cannot allocate memory'')
3. dom0 panic booting an 64bit SMP HVM guest:
(XEN) malloc vlapic regs error for vcpu 1)
These may be fixed but I''m unable to verify until
failure #3 is corrected:
6. 32bit SMP (pae) XEN panic in:
sh2_page_fault__shadow_3_guest_3+0x493/0xdd0
NOTE: On c/s 11269 sh2 becomes sh
7. 32bit SMP (pae) Guest domain crash:
sh2 error: sh2_remove_shadows(): can''t find all
shadows of mfn 10ef3 (shadow2_flags=00000100)
domain_crash called from shadow2-common.c:2251
NOTE: On c/s 11269 sh2 becomes sh
