| Live Migration of EL4U6 PVHVM virtual machine fails |
| Live migration of EL4U6 PVHVM virtual machine |
| xm migrate command hang or virtual machine boot on the destination server hangs. |
| Bug fix is available, upgrade the virtual machine kernel version to 2.6.9-67.0.22.0.1 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 |

| Live migration of EL5U2 x86_64 PVHVM virtual machine may panic |
| Live migration of EL5U2 x86_64 PVHVM virtual machine. |
| Migration of EL5U2 x86-64 PVHVM virtual machine fails with the xm migrate command completing but the virtual machine panics on the destination machine. |
| Bug 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. |

| Unable to boot PVHVM virtual machine after adding second disk as SCSI |
| 32 bit PVHVM virtual machines with IDE (hda) as primary disk |
| Virtual Machine failure to boot or the newly added SCSI disk discovery failure |
| For 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. |

| EL4U6/U7/U8 PVM virtual machine scsi driver do not recognize scsi disk added by vm manager. |
| EL4U6/U7/U8 PVM virtual machine with IDE (hda) as primary disk |
| Virtual Machine failure to recognize the newly added SCSI disk |
| Remove 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 2.6.9-67.0.22.0.1.ELxenU kernel, mkinitrd --omit-scsi-modules --with=xenblk --with=xennet /boot/initrd-2.6.9-67.0.22.0.1.ELxenU.img.scsifix 2.6.9-67.0.22.0.1.ELxenU |

| Startup of multipathd results in cannot open /sbin/dasd_id and /sbin/gnbd_import |
| None so far |
| When 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 |
| Fixed in OVM 2.2. For OEL5U3 and OEL5U4, contact Oracle support |

| System time on virtual machine may drift |
| Applications that require time synchronization across the servers or virtual machines. This affects both hardware virtualized and paravirtualized virtual machines. |
| The symptoms include the network to restart on a system configured with dhcp; cron jobs may not be executed at the required time. |
| To 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". |
