I recently upgraded by OVM to 3.4.3(.1511), but now my Oracle Enterprise Linux 6.9 PVM guests won’t start up any more. They don’t finish the ‘Starting automount’ in the boot / startup screen. It does not fail, it just won’t continue.
There is nothing special in the /etc/fstab I guess… : Continue reading
Ok, I added a new disk (well old actually, but new for the machine) to my Oracle VM server. It discovered it (or do it manually) and I wanted to create a new repository on it. Unfortunately it came with the following error:
Server error: 'The backing device /dev/mapper/3500a075109146bee is not allowed to contain partitions'
During the installation of Oracle 12c (12.1) I encountered the following error:
Error in invoking target 'irman ioracle' of makefile
See '/u01/app/oraInventory/logs/installActions2015(...).log' for details.
Inside the logfile the following error is encountered:
INFO: collect2: ld terminated with signal 9 [Killed]
According to metalink doc 2040972.1 this is due to less memory available (in a VM environment). Continue reading
It seems Oracle VM (<=3.3.1 *) and Oracle Linux (<= 5.10/6.6 *) both install ISOs and installed OS’s are not capable of booting when UEFI on the bare-metal hardware is used. I have seen two configurations now where this happened, one using a USB HDD drive capable providing a ISO to boot from as CD/DVD (Zalman ZM-VE300) and one HP iLO4 (http and local ISO) ‘remote’ booting.

After updating Oracle Linux 6.3 to 6.4 or installing 6.4 from scratch will give a corrupt (blank) VNC remote console when launching the console from Oracle VM Manager:
As discussed in https://oss.oracle.com/ol6/docs/RELEASE-NOTES-U4-en.html#idp513536 and Oracle Support note ‘Corrupted VNC console in PVM guests running Oracle Linux 6.4 on Oracle VM’ (Doc ID 1537278.1), this issue is addressed in ‘X Window System Does Not Run in a PVHVM guest’.
Uninstalling the xorg-x11-drv-cirrus guest driver solves the issue
If you uninstall the xorg-x11-cirrus driver from the guest OS, it will solve this issue.
# rpm -ev --nodeps xorg-x11-drv-cirrus
Reboot the guest OS after uninstalling.
I have been trying to run VBoxManage.exe from the Windows Task Scheduler to periodically list vms. The problem I had was that it wouldn’t list the VM’s I had registered, even if the task was run as the user that created the VM’s and with the ‘Run with highest privileges’ selected.
When searching the Internet, I saw more people having difficulties running it this way, so I started experimenting. Using ‘psexec‘ and ‘runas’ (use the /savecred option and run it once manually from command line) did work when running the VBoxManage.exe as the VM’s creator user while being logged as someone else, but running it from the Task Scheduler still did not work.

I had a virtual machine in VirtualBox for an OracleVM Server to test an OracleVM setup, but it froze every 5 minutes and had to restart the OVS again and again.
I got this tip from Robert Pastijn, Oracle Netherlands; When you create a virtual machine in VirtualBox for OracleVM Server, do _not_ choose the ‘Intel PRO’ type adapter type, but the ‘PCnet-FAST‘ one!
You can update your Oracle VM Servers (3.x) with the Oracle Public Yum Server. In the Oracle VM Manager console go to the ‘Tools and Resources’ tab and click ‘Server Update Management (YUM)’.
For the ‘YUM Base URL:’, use:
When enabling the GPG key, use:
(Oracle VM 3.x is based on OEL5) Continue reading
If you don’t want to use Null, Guest or External Host authentication when using VirtualBox Remote Display, one can add an extra external option called VBoxAuthSimple as explained here: http://www.virtualbox.org/manual/ch07.html#vbox-auth . You will use a separate password for connecting remotely to the VirtualBox’ Guest. This username/password will be stored in the machine’s XML settings file.
(trouble with mstsc.exe?)
I had this problem, when trying to connect with the External Authentication Method, using the Remote Display server in VirtualBox (4.1.8 and 4.2.0). When I want to connect with Microsoft’s Remote Desktop (mstsc.exe), it failed every time with “Your Remote Desktop session has ended. Your network administrator might have ended the connection (…)”.
