    Installing Solaris 10 in VirtualBox (watch that memory setting)

    During a recent Solaris 11 Hands on Workshop, a couple of attendees mentioned troubles installing Solaris 10 as a VirtualBox guest. In truth, it had been quite a while since I last installed Solaris 10, so I was unable to help at that particular moment, other than to recommend verifying the md5 checksum of the downloaded ISO image - a very common installation problem.

    Thinking a bit more about this, the last time I installed Solaris 10 as a guest was 10/08 (u6) and it would have been on version 3.something of VirtualBox. Thanks to Live Upgrade and VirtualBox's cloning and snapshot capabilities, I really haven't had a reason to install anything newer. Until now.

    Trying to duplicate my customer's problems, I grabbed a copy of the Solaris 10 8/11 ISO image from the Oracle Technology Network and verified the MD5 checksum. I then configured a guest VM with the following settings:

    • CPU: 1
    • Video Memory: 32MB
    • Base Memory: 1024MB
    In other words, a pretty basic 1GB guest machine. More important, it is exactly the same configuration as the half dozen or so other guests that are running 8/11 just fine, courtesy of Live Upgrade.

    After starting the guest machine with the Solaris 10 8/11 ISO image in the CDROM device, you quickly get a kernel oops that looks something like this.

    Click image to enlarge

    That's not quite what I expected, but it does look like what the workshop attendees were describing. Trying Solaris 10 10/09 (u8) produces slightly different results (the guest quietly stalls), but ultimately ends up in the same place - a failed installation. This led me down a path of changing the chipset to ICH9 and enabling IO APIC which helped with u8, but the u10 install was still punting.

    Then I remembered reading something in the release notes about the minimum memory requirements bumping up. Sure enough, when I look up the System Requirements in theSolaris 10 8/11 Installation Guide, I see that the minimum memory size for x86 is now 1.5GB. After adjusting the base memory to 1500MB in the guest, the installation completes as expected.

    The moral to this story is that minimum system requirements are documented for a reason and they really should be followed.

    VirtualBox 3.1 Beta 3 now available for download

    The third beta release of VirtualBox 3.1 is now available for testing. You can download the binaries for all platforms at http://download.virtualbox.org/virtualbox/3.1.0_BETA3/

    In addition to the new features introduced with Beta 1 (live migration, branched snapshots, new OpenSolaris USB support, 2D video acceleration, network changes while VM is running), the following are noteworthy changes since Beta 2.
    • VMM: fixes slow OpenSolaris booting (3.1.0 Beta 1 regression)
    • GUI: prevent hints being send for guest-initiated resizes
    • GUI: fix for saved mouse shape data which was incorrectly updated
    • Xml compatibility fixes with 3.0.x (CpuIdTree element)
    • Storage/VMDK: fix buffers for really huge VMDK files split into 2G pieces
    • EFI: added 64-bit firmware
    • 2D support: Saved state save/restore fixes
    • 2D support: fixed VM reset issues
    • Snapshots: suppresses the automatic resetting of immutable disk images on VM power-up if the machine has snapshots AND the current snapshot is an online snapshot, to avoid data corruption (the machine would otherwise be reset to a state which is equivalent of a poweroff of a running machine without a proper shutdown)
    • Guest Additions: fixed a rare guest crash with 2 or more guest CPUs
    • Windows Additions: improved file version lookup for guest OS information
    • Windows Additions: disabled some debug output
    • Linux Additions: fixed guests with Linux 2.4 kernels
    • Linux Additions: removed debugging symbols to save space (3.1.0 Beta 2 regression)
    • X11 Additions: fixed a bug which re-enabled the graphics (and dynamic resizing) capability when disabling seamless
    • X11 Additions: added more default resolutions for old guests
    • X11 Additions: workaround a bug in X.Org 1.3 which caused dynamic resizing to fail


    Please refer to the VirtualBox 3.1 Beta 3 Changelog for a complete list of changes and enhancements.

    Important Note: Please do not use this VirtualBox Beta release on production machines. A VirtualBox Beta release should be considered a bleeding-edge release meant for early evaluation and testing purposes.

    VirtualBox 3.0.12 has been released for all platforms. 3.0.12 is a maintenance release.

    Changes in VirtualBox 3.0.12 include
    • VMM: reduced IO-APIC overhead for 32 bits Windows NT/2000/XP/2003 guests; requires 64 bits support (VT-x only)
    • VMM: fixed double timer interrupt delivery on old Linux kernels using IO-APIC (caused guest time to run at double speed)
    • VMM: reinitialize VT-x and AMD-V after host suspend or hibernate; some BIOSes forget this (Windows hosts only)
    • VMM: fix loading of saved state when RAM preallocation is enabled
    • BIOS: ignore unknown shutdown codes instead of causing a guru meditation
    • GUI: never start a VM on a single click into the selector window
    • Serial: reduce the probability of lost bytes if the host end is connected to a raw file
    • VMDK: fix handling of split image variants and fix a 3.0.10 regression
    • VRDP: fixed occasional VRDP server crash
    • Network: even if the virtual network cable was disconnected, some guests were able to send / receive packets (E1000)
    • Network: even if the virtual network cable was disconnected, the PCNet card received some spurious packets which might confuse the guest
    • Shared folders: fixed changing case of file names
    • Windows Additions: fix crash in seamless mode
    • Linux Additions: fix writing to files opened in O_APPEND mode
    • Solaris Additions: fix regression in guest additions driver which among other things caused lost guest property updates and periodic error messages being written to the system log
