Browse Published Validated Configurations  >  Validated Configuration Details
Program Scope

The goal of this program is to validate hardware with Oracle Linux and Oracle VM, and to identify issues and configuration details that would impact customer deployments. Oracle developed the program to go far beyond the standard certification testing normally performed with operating systems. Hardware vendors participating in this program perform thorough testing of the hardware in real-world configurations with Oracle Linux and Oracle VM.

This is not a database certification. Oracle Database is a component of the environment because it is demanding on hardware resources (processor, memory, cache, storage, network) and the operating system, and well suited for this advanced level of testing. The validation program uses Oracle Database as a tool and hardware is not certified with Oracle Database as a result of the validation program.

For more information please see the program's Frequently Asked Questions (FAQ).

Bug No7442030
SummaryLive Migration of EL4U6 PVHVM virtual machine fails
AffectsLive migration of EL4U6 PVHVM virtual machine
Symptomxm migrate command hang or virtual machine boot on the destination server hangs.
Solution/WorkaroundBug fix is available, upgrade the virtual machine kernel version to 2.6.9- or higher for OEL 4.6 and upgrade to pvdriver version kmod-xenpv-smp-0.1-10.0.1.el4.i686.rpm or higher. On server, upgrade xen version to xen-3.1.4-0.1.21.el5.i386 or higher
Bug No7483238
SummaryLive migration of EL5U2 x86_64 PVHVM virtual machine may panic
AffectsLive migration of EL5U2 x86_64 PVHVM virtual machine.
SymptomMigration of EL5U2 x86-64 PVHVM virtual machine fails with the xm migrate command completing but the virtual machine panics on the destination machine.
Solution/WorkaroundBug fix is available, upgrade to pvdriver version kmod-xenpv-0.1-9.0.1.el5.i686.rpm or higher. For virtual machine, recreate the virtual machine initrd image and reboot the virtual machine.
Bug No7528612
SummaryUnable to boot PVHVM virtual machine after adding second disk as SCSI
Affects32 bit PVHVM virtual machines with IDE (hda) as primary disk
SymptomVirtual Machine failure to boot or the newly added SCSI disk discovery failure
Solution/WorkaroundFor EL4 virtual machine adding "alias sym53c8xx off" in /etc/modprobe.conf files prevent crash when "sda" entry is added (scsi disk) in vm.cfg file and For EL5 virtual machine, remove sym53c8xx.ko from /lib/modules/`uname -r`/ directory.
Bug No7528616
SummaryEL4U6/U7/U8 PVM virtual machine scsi driver do not recognize scsi disk added by vm manager.
AffectsEL4U6/U7/U8 PVM virtual machine with IDE (hda) as primary disk
SymptomVirtual Machine failure to recognize the newly added SCSI disk
Solution/WorkaroundRemove the SCSI driver from the virtual machine initrd image and reboot the virtual machine , E.g.: Command to remake initrd image without SCSI module (scsi_mod.ko) for 2.6.9- kernel, mkinitrd --omit-scsi-modules --with=xenblk --with=xennet /boot/initrd-2.6.9- 2.6.9-
Bug No8499326
SummaryStartup of multipathd results in cannot open /sbin/dasd_id and /sbin/gnbd_import
AffectsNone so far
SymptomWhen starting multipathd, you see the following errors:multipathd: cannot open /sbin/dasd_id : No such file or directory,multipathd: cannot open /sbin/gnbd_import : No such file or directory
Solution/WorkaroundFixed in OVM 2.2. For OEL5U3 and OEL5U4, contact Oracle support
Bug NoOracle Bugzilla 4818
SummarySystem time on virtual machine may drift
AffectsApplications that require time synchronization across the servers or virtual machines. This affects both hardware virtualized and paravirtualized virtual machines.
SymptomThe symptoms include the network to restart on a system configured with dhcp; cron jobs may not be executed at the required time.
Solution/WorkaroundTo maximize clock accuracy, ntp service should be enabled in domain0.For PVM virtual machines perform the following steps: (1) Edit /etc/sysctl to set xen.independent_wallclock to 1; run sysctl -p to make the change effective; (2) Enable ntp service: chkconfig ntpd on; service ntpd start. For PVHVM virtual machines perform the following steps: (1) Verify that timer_mode parameter in vm.cfg is set to 0 for 32bit Linux, 1 for Windows, and 2 for 64 bit Linux. With OVM 2.1. release, these values should be set manually. In OVM 2.1.1 and higher versions, those values are set automatically if the virtual machine is created by Oracle VM manager or by virt-install command invoked with --os-type and --os-variant options (2) modify /etc/grub.conf in the virtual machine to add kernel parameters "clock=pit nohpet nopmtimer".
