virtualbox.org

Host: Ubuntu 8.04 32 bit on AMD 2.4 Ghz, 2 gigs RAM running Virtualbox 2.0.4
Guest: Windows XP SP3 with 512MB RAM allocated


If iTtunes is running (idle) CPU usage on the Ubuntu host hovers at around 60%. CPU usage on the XP guest is minimal. If I try to do anyting with iTunes, CPU usage on the Ubuntu host if peaked at 100%, which maked iTunes very slow and unusable. If I close iTunes, CPU usage drops to nothing.

Same occurs on laptop with dual core 2.5Ghz and 4 gigs of RAM. running Ubuntu 8.04 64 bit as host. CPU usage hovers at around 40% when iTunes is idle in the XP guest

Tried the following without any success.
- disable iTineshelper (found this in another post)
- disable any additional apps/services such as antivirus

Anyone else have this problem?

confirming the same on Ubuntu Intrepid, WinXP Sp2 + iTunes 8.0.1.. It simply makes everything unusable. pls pls pls fix!

I too can confirm that Itunes 8 runs REALLY slowly. I usually have to change to another window manager (Enlightenment) to even make it respond.

Same here .

Me too.

Me three.

Trying to do a similar thing, what I have observed so far...

Disable the clipboard for the guest helps.
Disable the USB adapter for the guest helps.
When I was running XP for iTunes, I allocated 384 MB to the guest and disabled the page file which also helped.

Only been trying this for two days, but using Windows Server 2003 w/ 384 MB of RAM for the guest results in more responsive results for me.

Not a clear answer, just observations so far.

Same here, Windows XP guest on Archlinux 2.6.28 host with VB 2.1.0.
