Ubuntu guest runs very slow with VBox 3.2.0

Host type: Windows

Description

I installed VBox 3.2.0 on Windows 7 64-bit, Intel i3 laptop.

When I installed Ubuntu 10.04, it took hours to finish and took minutes to boot to shell.

Then I removed 3.2.0 and installed 3.1.8, using same vdi and VM configuration, it took 5 sec to boot to shell. Other operation noticeably ran faster in VBox3.1.8.

The log attached.

Does it make any difference if you turn off nested paging?

comment:2 Changed 4 years ago by ezjd

Yes, disabling nested paging does make big difference as Guest is pretty much usable. I also notice that in 3.1.8, nested paging is enabled.

Could you attach the log of a 3.2.0 session with nested paging disabled? Can you confirm that performance is as expected with nested paging off or not?
