vbox4.3.26 and Oracle Linux 6.3 boot console can't show

[fkong2000]

Recently I download one linux ova file and import into vbox 4.3.26. The vbox is runing on Win7 64bit. After successful importing and start this new oracle linux 6.3 vm, I cannot access the VM console but from "Preview" I can see it startup screen until login screen shows. trying many tweaks including give "Display" 32 MB video memory and recreate importing several times, still same. I have other VMs never met such issue, once started, the boot console will automatically popup. only this VMs, I never can access popup boot console, I can see progress only in "preview".

Can someone help, Thanks so much!!

This question does not seem to concern "Using VirtualBox". Moved to "Linux Guests".

Please post a VM log file. Right click VM in GUI, select "Show Log", save "VBox.log" (only) to a file, zip file and attach here. Make sure the VM is shut down before you collect the log of the session.

The issue is solved by extended desktop display.
