10.1 ISO Image Attached to Virtual Machine Is Not Uploaded

When you try to export a virtual machine with an attached ISO image from Oracle VM to Oracle Cloud Infrastructure, the Export VM to OCI wizard does not list the ISO image in the Boot Disk or Additional Disks lists. The attached ISO image does not upload.

Workaround: There is no workaround for this issue.

Bug 31202000

10.2 Export Process Is Aborted If Oracle VM Exporter Appliance Is Restarted or Stopped

When you restart or stop the Oracle VM Exporter Appliance during the export process, the export process fails with an error message.

Workaround: Resume the export operation from Oracle VM Manager once the Oracle VM Exporter Appliance is up and running or do not restart and stop the virtual machine during the export process.

Bug 31233553

10.3 Export Virtual Machine Job Hangs After Disabling the Storage Network Interface

If the Oracle VM Exporter Appliance has a vNIC connected to a separate storage network and during the export you disable the storage NIC, the export job should fail gracefully. Instead it remains in a Converting disk image... state because virt-v2v does not timeout or error out when the network connection to storage is lost.

Workaround: You have the following options to workaround this issue:

Review the /var/log/vmexporter/virt-v2v_vm_id.log file to check and see if virt-v2v is stuck waiting or still progressing.
Abort the job.
Retry the export. If the storage network connection is still out, you receive an error. If the network connection exists, the job resumes restarting at the virt-v2v conversion.

10.4 An Oracle Linux 5 Virtual Machine Instance Cannot Be Accessed Using SSH or Serial Console

When an Oracle Linux 5 (64-bit or 32-bit) virtual machine is exported to Oracle Cloud Infrastructure, you cannot ssh to the virtual machine instance or access it using a serial console.

Workaround: There is no workaround for this issue.

Bug 31187778

10.5 Oracle VM Manager Limits VMAPI Messages to 1024 Characters

When you configure a virtual machine to send VMAPI messages and select the Log Message check box in the Create VM Message dialog box, you get a pop-up error stating the number of characters is out of range because the Oracle VM Manager certificate is a string of more than 1400 characters. Only messages containing between 1 and 1024 characters can be logged. If you attempt to log the message using the Oracle VM Manager Command Line Interface, you get a Job failed on Core error message.

Workaround: Do not check Log Message during Oracle VM Exporter Appliance provisioning because the Oracle VM Manager certificate that is sent using VMAPI is a string of more than 1400 characters.

Bug 31085768

10.6 UI Allows Setting of Incorrect Boot Volume Size for Windows Virtual Machine

Even though the valid boot volume range for a Windows virtual machine is between 256 GB and 32 TB, the Oracle VM Manager Web Interface logic lets you set the boot volume size outside of this range.

Workaround: Set the Windows virtual machine boot volume size within range of 256 GB and 32 TB.

Bug 31353494

10.7 ovmd Service Start Is Delayed for Exported Oracle Linux 6 Virtual Machine

If you create an Oracle Linux 6 virtual machine with ovmd service enabled and export the virtual machine to Oracle Cloud Infrastructure, it takes several minutes for the ovmd service to start in Oracle Cloud Infrastructure.

Workaround: Stop the ovmd service using chkconfig ovmd off and restart the virtual machine in Oracle Cloud Infrastructure.

Bug 31323718

10.8 Export of a VM fails but does not abort cleanly because the Oracle Cloud Infrastructure network is down

The export of a VM fails because the network connection to Oracle Cloud Infrastructure has failed. A restart of the export of the failed VM displays the message An export operation is already in progress for VM vm-name.

Workaround: Either (1) wait until the export operation fails gracefully after the Oracle Cloud Infrastructure timeout for the operation, or (2) restart the Oracle VM Exporter Appliance, which aborts all running export jobs.
