    VirtualBox memory leak and high CPU utilization

    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?

    Similar issue on 32-bit, lucid host. Lucid-guest slowly eats all available memory in 5-8 h (but does not kill host, just becomes unusable/unresponsive/black screen). Sure looks a lot like a mem-leak.

    Anyone here ever solve the problem or suggest another distro that would be easy to setup and install.

    I can also tell you I have this bug. It seams if I set low enough ram it does not happen but if I put to much ram into the VM being 64bit the ram will slowly eat up till she goes booom.


    This really really blows btw I used the installer script on the xen wiki I use this as my statup:

    Code:
    -- quiet console=hvc0 partman/default_filesystem=ext3

    I hope someone found a cure for this.

    I also have this bug.
    Slowly the _host_ memory gets eaten up, but the guest stays the same, more or less.

    I get this problem whenever I run VirtualBox, whether it's a Win XP Guest or an Ubuntu Guest.

    I'm running Virtual Box 3.2.10 on Ubuntu 10.04 64 bit.

    Even after I close Virtual Box my system is still using 60% of its ram (4 GB). But when I open up the system monitor I can't find the culprit.

    Looks like a memory leak..
