Subject: Testing status of HVM (Intel VT) on 64bit XEN unstable c/s 12472
Date: Fri, 17 Nov 2006 13:27:48 -0500 [thread overview]
Message-ID: <455DFF24.5000307@virtualiron.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 4150 bytes --]
Summary:
Changeset 12472
- 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

Failures:
1. BUG 666: 32bit guests fail ltp gettimeofday02
and nanosleep01/02 with clock problems
2. 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')
4. FIXED: HVM guests boot up but do not see the network
