Description (last modified by aeichner) (diff)

I have a Centos 5 Host and I install a Debian Lenny Guest. It's a 4 GB RAM/Dual Xeon Server. I create the VM with only 200 MB and when I do simple tasks (like an apt-get), I got this error.

Bellow, the tail of VBox.log and the free command. I don't understand why I have a lot of buffers and cached memory (2.5 MB) and the system can't allocate this. Have I do tune any sysctl parameters to coorect this ???

Please retry with 2.1.4. In case this happens again, please attach the whole VBox.log file.

Best regards.

Interesting. Btw, you should install the RHEL5 rpm which should fit better to the CentOS host.

Not able to reproduce with a PAE kernel on CentOS 5.2, though with a 2GB system. Please could you attach the output of dmesg after you tried to start the VM?

Hi Frank. I installed whe rpm version from site (VirtualBox-2.1.4_42893_rhel5-1.i386.rpm).

adaldeia@server1 [~]# uname -a Linux 2.6.18-92.1.10.el5.centos.plusPAE #1 SMP Thu Aug 7 12:55:59 EDT 2008 i686 i686 i386 GNU/Linux

I use the VBOXHeadless to start the machine because this is a remote server. This Debian VM, the system starts normally, but after sometime it freezes, with the error explained by VBox.log. I tried to install OpenSUSE and the error occurs in the instalation. This machine has the VirtualBox 1.6 version. I removed it with rpm -e and then install the 2.1.2 and 2.1.4. I sucessfull installed the debian in VirtualBox 1.6... When I install the 2.1.2, I removed the .VirtualBox dir to start again with a new Debian and OpenSUSE, without success.

Why the Centos does not reclaim the cache space to supply more 'normal' memory ?

Please could you check if this problem still happens with the last release (2.2.2)? There were some important memory-related changes.

comment:7 Changed 9 years ago by adaldeia

Hi frank,

After update to 2.2.2, the problem has not been solved yet. But I update the kernel too (2.6.18-128.1.6.el5.centos.plusPAE) and recompile the module. After this, everthing is fine !!!

Thank you very much and thanks to all VB team for this awesome product !
