VirtualBox in unRAID

lainie · August 19, 2012

Memory problem ??

I have been getting the attached memory allocations errors recently (also under unraid v4.7 and v5.0).

They appear every couple of minutes.

Can someone assist?

Are you switching back & forth between 4.7 & 5rc6 on the same box?

I have not come across the errors on my box, but scanned google to see what others have. It would not hurt to run a memory test to check that your ram is ok, but seems like it could be some other things as well.

When you get errors like this, what VMs are you running?

Is it VMs you just created or are you importing old ones? Guests created prior to version 4 can be imported, but several things have to be done.

Are you running multiple VMs at once when this starts occurring (how heavy a load is it on your system).

What does free -m & vmstat look like before & after you start VirtualBox?

You previously stated you had VirtualBox set to start before the go file is run by placing it in the extras directory. To troubleshoot, try having it not start automatically, run some commands to see how the system's memory is doing... then run the commands again when starting VirtualBox & each VM to see if you can determine if the problem is due to not enough memory.

Looks like VirtualBox is now available as version 4.1.20.

I should have some time this weekend to compile the new version. I will do it for the same versions of unRAID that I currently have up... unless I see any requests for different versions.

Will update this thread once I have completed it.

Also a difference in your go file is the line "VBoxManage setproperty websrvauthlibrary null". TBoomer2 used this command & was having an authentication issue. I have not had to use this command. I would recommend trying to start VirtualBox with just the 3 commands above. If you run into issues with authenticating, then can try changing this later. I am not sure it is necessary.

The first line of errors you listed is saying a file cannot be found. I suspect that is due to not running installpkg. Let me know what you find with the above information & if you get it working for you. Good luck.

Just to clarify - I was getting this error before changing the authentication to null. Null seemed to permit access into phpVirtualbox and I had no issues spawning the Headless services after that.

Ah, I misunderstood... I never had to make that change & it seemed like that was something you tried after you ran into the problem. Thank you for clarifying.

Did you try running VirtualBox as another user aside from root? I recently changed several of my addons to use nobody, but have not tried changing VirtualBox yet.

Hi lainie,

this is my config:

unraid 5.0rc5

using these commands in my go script

installpkg /mnt/cache/install/VirtualBox-4.1.8-unRAID.tgz

vboxwebsrv -b -H 127.0.0.1 --logfile /dev/null >/dev/null

VBoxManage extpack install /boot/packages/Oracle_VM_VirtualBox_Extension_Pack-4.1.18-78361.vbox-extpack

Thanks for all the work. i am having issues with phpvirtualbox. i installed simplefeatures and the web server. all that is running good. everything installs correctly. i have the web server pointing to my cache drive where i have the www files. i even eddited the config file to add my username and password because when i would go to the site it would tell me that there was no config file. so i added that and still cant get into it. i am using admin admin. i need your guidance. getting so fristrated with this thing.

waveworm · August 24, 2012

i get error "Could not connect to host (http://127.0.0.1:18083/)"

I have also had problems accessing phpvirtualbox (see above a few posts).

try changing the following:

set the authentication to off "var $noAuth = true;" in the config.php file (under phpvirtualbox folder).

Hope it help, it did for me

also please check if you have a folder in your flash drive "/custom/vbox"

waveworm · August 24, 2012

Theone,

Thanks for your fast response. i had done that to take away the username and password but still no luck. now it says

"An error occurred communicating with your vboxwebsrv. No more requests will be sent by phpVirtualBox until the error is corrected and this page is refreshed. The details of this connection error should be displayed in a subsequent dialog box." i created that folder on the flash and still nothing.

waveworm · August 24, 2012

do i need to reboot or restart the server? should i stop vbox?

theone · August 24, 2012

do i need to reboot or restart the server? should i stop vbox?

try clearing the browser cache and restarting the server.

JonathanM · August 24, 2012

vboxwebsrv -b -H 127.0.0.1 --logfile /dev/null >/dev/null

I'm going to show my ignorance here, in that I am going to tell you to change something and I don't actually know why the change worked for me. Change the loopback address of 127.0.0.1 to your servers actual IP address and see if it starts working. You don't have to reboot the machine, just issue that command at the console, i.e.

vboxwebsrv -b -H [actual ip here] --logfile /dev/null >/dev/null

and try reloading the phpvirtualbox page.

lainie · August 24, 2012

I have the compiled versions for the newest 4.1.20 version of VirtualBox up on my SkyDrive.

I have created a directory called "archived" on my SkyDrive share. I moved all the VirtualBox 4.1.18 files into archived.

Will rewrite my instructions for version 4.1.20 later this weekend.

If you have VirtualBox 4.1.18 running the way you like it, there may be no reason to upgrade. Seems like the problems being posted are coming from configuring phpvirtualbox. The version of phpvirtualbox to use did not change (I am still using phpvirtualbox-4.1-8 ~ VirtualBox 4.1.x Compatible).

Actually that may be something to check if you are having problems with phpvirtualbox... just double check yourself to make sure you downloaded phpvirtualbox-4.1-8.zip ~ VirtualBox 4.1.x Compatible as opposed to phpvirtualbox-4.0-7.zip ~ VirtualBox 4.0.x Compatible.

From the VirtualBox website, this is what changed between version 4.1.18 to version 4.1.20:

VirtualBox 4.1.20 (released 2012-08-20)

This is a maintenance release. The following items were fixed and/or added:

VMM: fixed a crash under rare circumstances for VMs running without hardware virtualization

VMM: fixed a code analysis bug for certain displacement instructions for VMs running without hardware virtualization

VMM: fixed an interpretion bug for TPR read instructions under rare conditions (AMD-V only)

Snapshots: fixed a crash when restoring an old snapshot when powering off a VM (bugs #9604, #10491)

VBoxSVC: be more tolerant against environment variables with strange encodings (bug #8780)

VGA: fixed wrong access check which might cause a crash under certain conditions

NAT: final fix for crashes under rare conditions (bug #10513)

Virtio-net: fixed the problem with receiving of GSO packets in Windows XP guests causing packet loss in host-to-VM transfers

HPET: several fixes (bugs #10170, #10306)

Clipboard: disable the clipboard by default for new VMs

BIOS: the PCI BIOS was not properly detected with the chipset type set to ICH9 (bugs #9301, #10327)

Mac OS X hosts: adaptions to Mountain Lion

Linux Installer: fixes for Gentoo Linux (bug #10642)

Linux guests: fixed mouse integration on Fedora 17 guests (bug #2306)

Linux Additions: compile fixes for RHEL/CentOS 6.3 (bug #10756)

Linux Additions: compile fixes for Linux 3.5-rc1 and Linux 3.6-rc1 (bug #10709)

Solaris host: fixed a guru meditation while allocating large pages (bug #10600)

Solaris host: fixed possible kernel panics while freeing memory

Solaris Installer: fixed missing icon for menu and desktop shortcuts

waveworm · August 24, 2012

could it be the version of PHP installed? i originally had unraid-web installed through unmenu. i removed that and disabled php from installing automatically through unmenu, however, it still says php is installed but newer then the one available. but i know that simple-features web server comes with php so im guessing thats why.

i did change the ip address of

vboxwebsrv -b -H [actual ip here] --logfile /dev/null >/dev/null

to my own settings. but still nothing.

Dunno if it was the correct thing to do, and may be why I edited my vboxwebsrv file, but I also changed that loopback address to my server ip to make my setup work.

after i did that it added about 10sec of loading and then the same message!

lainie · August 24, 2012

I recently (within the past week) uncommented the line for "var $noAuth = true;" in my config.php file so I am no longer prompted to login with the admin / admin when bringing up http://lament:8084/phpvb/

The default user / pass lines, I left alone. I do not have an unRAID user named vbox.

Except for uncommenting the noAuth line, I believe this file was left exactly how I downloaded it. Could that be the problem? You changed the 2 lines containing the user / pass to a user on your unRAID when it should have been left default? Or did you try changing these lines after you experienced issues getting phpvirtualbox to come up?

Another thought. It has been awhile since I managed a web server for others in my job. When I use a web server, I create subdirectories for anything I download. Like in this case, my web directory contains a directory named phpvb. Inside phpvb, I have all the phpvirtualbox files. When I access phpvirtualbox, I use http://lament:8084/phpvb/ instead of having it installed in the root directory using just http://lament:8084/.

I mention this because I vaguely remember the default settings of some web servers that I managed in the past not displaying some php pages correctly. We tried & tried to use the root directory, but something prevented it from working (& I can't remember what it was). Ever since I have just used subdirectories if I am using files created by someone else. I will usually create my own basic html file that provides hyperlinks to the subdirectories & my html files worked.

Like I said this is just something I vaguely remember happening... but if the above changes do not work, well it is something else to try.

Thanks for all the replies. i have copied everything that you posted into my php config file and saved it and im still getting the same error.

is there a way for me to confirm that the web interface portion of VB is running for virtualbox? i know that the web portion of simplefeatures are working.

im at a loss of what to try next. i am not sure i didnt screw something up with trying to install virtualbox the original way earlier in the post by trying to build the headers and linux. but i have rebooted since then and everything else is working as it should.

I think that means that vboxwebsrv is already running. Does it show on a ps list? If so, try killing the process and start it again.

waveworm · August 25, 2012

i set this up all on a new flashdrive. and still cant get it to work. same issues.

lainie, would you mind zipping up your unraid flashdrive I'm contents and putting that in your skydrive? so i can take a look at it and see if it works on my end? thanks

lainie · August 25, 2012

Please post your output for:

ps -ef | grep ox

Looks like you may already have some of it running.

When you reboot, the headers you have built go away. I don't think that will be the problem.
