[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Testing status of fully virtualized guests (Intel VT) on 32bit XEN unstable
* NEW: My 32bit XEN builds are still not PAE enabled. Chasing done
why this is. For now I stopped running the 32b SMP Guests.
Test Configuration:
Dell PowerEdge 430, Dual Core, 2GB, 3 SATA (Intel VT)
32bit XEN PAE Hypervisor on a RHEL4U2 32bit root (/dev/sda)
dom0_mem=256M (required to boot domUs)
32bit fully virtualized (HVM) guest RHEL4U2 256MB (/dev/sdb)
pae=0, acpi=1, apic=1
kernargs clock=pit
32bit fully virtualized (HVM) guest RHEL3U6 256MB (/dev/sdc)
pae=0, acpi=1, apic=1
kernargs clock=pit
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:
851 tests (850 ltp tests and one 30 minute user load test)
Tests are marked #Pass/#Fail where (n) points to a failure description

----------------------------------------------------------------------
Failures:
1. 32 bit SMP guests hang on boot
"Uncompressing Linux... Ok, booting the kernel."
2. 32bit UP guest fail ltp gettimeofday02
"Time is going backwards"
3. [Fixed in 9920] Build broken:
cc1: warnings being treated as errors
mm.c: In function subarch_init_memory:
mm.c:163: warning: format %ld expects type long int,
but argument 2 has type unsigned int
mm.c:163: warning: format %ld expects type long int,
but argument 3 has type unsigned int
4. The RHEL3 UP tests run OK however they take 12 hours
to complete where on RHEL4 UP the run for ~4 hours.
There seems to be some performance issue running a
2.4 kernel fully virtualized guest. One test in
particular ltp's aso-stress025 takes 4 hour to run
on RHEL3U6-32b while it take 4 minutes on RHEL4U2-32b.
