VirtualBox - crashing / freezing

Sat, 05 Sep 2009 00:00:00 +1200

I’ve had some problems since my upgrade to virtualbox 2.2.0 on OpenSolaris. After some time all of my linux boxes seem to just die. The virtual machine just stops responding. Strangely there was no problem with my windows vms after the update.

From what i can tell it looks like the upgrade turned off “IO APIC” - this is the bit that seemed to cause the problem. Re-enabling this on all of my linux boxes seems to have fixed the problem. I’ll continue testing for another week and update this post if any problems re-occur.

OpenSolaris - Headless server

Sun, 26 Jul 2009 00:00:00 +1200

I’ve moved from a CentOS linux distro running vmware server 2.0 to OpenSolaris running VirtualBox. My previous system was totally headless and i wanted something similar to replace it.

I’ve just started getting into OpenSolaris for many reasons (Sun has some cool stuff - ZFS / VirtualBox). But I have always wanted to run OpenSolaris as a headless server, and from what i initially found VirtualBox didn’t have the easy to use autostart on boot features that vmware server had. But there are always ways to get things working…

VirtualBox - Dup on ping

Mon, 22 Jun 2009 00:00:00 +1200

I’ve had this with certain kernels (2009.06) on opensolaris. Seems there is some incompatibility between some kernels and the opensolaris virtualbox network emulation. This only seems to effect linux virtual guests.

When you try to ping an address you get something like this…

[root@VA-DHCPWEB ~]# ping 192.168.9.15 PING 192.168.9.15 (192.168.9.15) 56(84) bytes of data. 64 bytes from 192.168.9.15: icmp_seq=1 ttl=128 time=1.85 ms 64 bytes from 192.168.9.15: icmp_seq=1 ttl=127 time=1.88 ms (DUP!)

Linux - Installing VirtualBox additions

Wed, 04 Feb 2009 00:00:00 +1300

The following works on CentOs / Fedora / redhat etc…

Logon to your distro. The packages you need are the kernel-devel.i686, kernel.i686 (if not the latest), and gcc.i386 (complier)

yum -y install kernel.i686 gcc.i386

reboot as the kernel needs to load, then logon again install the kernel dev;

yum -y install kernel-devel.i686

Now you want to present the virtualbox additions to the cdrom drive on your distro. Click “install additions” on the virtualbox guest console.

OpenSolaris - Autologon

Thu, 29 Jan 2009 00:00:00 +1300

There are two ways to setup the auto login for OpenSolaris (2008.11);

One - You can fire up the GUI using gdmsetup. Update : this didnt actually work when i tried it recentely - it might not be in this release of opensolaris.

Two - go to /etc/x****11/gdm/custom.conf (in newer releases its just /etc/gdm/custom.conf) and manually modify the required fields in the [daemon] section and add the following;

[daemon] AutomaticLoginEnable=true AutomaticLogin=username

OpenSolaris - SMF and VirtualBox

Thu, 29 Jan 2009 00:00:00 +1300

So… i’m looking for a way to fire up some VirtualBox machines after a reboot on OpenSolaris. SMF is the key. Just need to create some XML docs that fire up a couple of headless vm’s.

Shouldn’t be too hard. Lets see what i can come up with.

Here is a good pdf about migrating Legacy RC services into SMF, which has given me a few pointers….
