Public bug reported:
Sluggish performance in Virtualbox after Natty->Oneiric upgrade.
Choppy audio, and poor disk I/O performance. Underlying system as VM
extensions enabled in the BIOS. I've experimented with the execute-flag
setting in the host's BIOS after some web-searches, but these have no
effect. The host has an SSD as main storage.
I've observed this with Windows 7 guests, and I haven't done anything
performance-sensitive with a non-Windows guest.
The VirtualBox Guest Additions appear to be up-to-date, and don't appear
to have changed since the version of VirtualBox I was using with Natty.
Also, the host was upgraded from Natty to Oneiric via the install CD.
This is not a fresh install.
The VM guests are just plain sluggish, and much slower than they were
before the Oneiric upgrade. Before the upgrade, VM guests were snappy,
and audio worked flawlessly.
I'll be happy to perform any additional diagnostic steps that you
suggest, especially since I haven't been able to isolate a cause for
this one.
Thanks!
