[Xen-devel] Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 11134
Summary:
Changeset 11134
- 64bit SMP HVM guests crash on boot since c/s 10070 (failure.5)
This happens with kernarg noapic. If you remove noapic it doesn''t
crash but the guest boots very slow and the guest network does
not come up.
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. Multiple HVM guests (32/64 SMP) crash under load:
32bit SMP guests fail various tests with:
"Couldn''t alloc shadow page!"
"domain_crash_sync called from shadow.c:445"
5. 64bit SMP HVM guests (noapic) crash on boot:
"Unable to handle kernel paging request at
