Im having strange problem on ubuntu 8.10
After few hours, guest machine (server 2003) starts to lag periodically every 1s for about 200-300ms (it completely stops down stops down for brief periods).

Log shows nothing suspicious.

Also guest machine sometimes start displaying 50% cpu in performance monitor - everything kernel times - while there is no user or system process using cpu..

Any ideas?

Log is here http://licho.eu/VBox.log

It usuallly takes more than 16 hours for lags to begin and they are becoming worse and worse.
50% cpu problem was unrelated one time thing.

Resolved this - was caused by intel 1000/t virtual network adapter.
Recreated machine and used defaul one - no more lags.
