I have 64-bit Karmic on my 8 GB box. Fresh VirtualBox 3.2.6.r63112 hosts freshly installed 64-bit Lucid with 4 GB of RAM dedicated to it. Guest additions are also freshly installed with the same VB version. There are two major problems:
1. Virtual machine always runs with 100% CPU utilized despite the fact that guest rarely climbs over 50%. The reason I can still use my host normally is that I dedicate to VM only one CPU out of four.
2. Withing 5 hours VM slowly outgrows its 4GB limit and takes all physical memory that is left - killing the host.
Is there anyone having similar problem?
