[SOLVED] Virtualbox hangs the host computer

Hi all,
It's been some time since I experience this annoying bug :
Virtualbox completely hangs my computer whenever I click on the "configuration" for any virtual machine.
Even the magic sysreqs keys are not able to recover (they are enabled in /etc/sysctl.conf) , I'm obliged to hard reboot my machine
However, I can go into other menus in the GUI without problems. VMs work ok as well.
My host system :
3.7.8-1-ARCH #1 SMP PREEMPT Fri Feb 15 03:39:05 EET 2013 x86_64 GNU/Linux
virtualbox 4.2.6-1
virtualbox-host-modules 4.2.6-6
no proprietary extension pack.
(kernel was upgraded today and the computer rebooted, virtualbox-host-modules were updated as well)
Using KDE 4.10
Nvidia integrated graphics (xf86-video-nouveau 1.0.6-1)
Thanks for any help on how to overcome this bug!

Problem seems to be solved.
All I did was to click "remove all the warnings" in the Help menu, and remove some older VM files which might have been corrupt.

May a recent i Mac be installed as the host computer for a wireless community

May a recent iMac be installed as the Host Computer for a wireless community. The present situation is; the iMac is subservient to the e Mac. I do not want to have two computers. I have one guest on the wireless.

There are some wireless external hard drives that can be used with the iPad.
The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.

Log data on the host computer using cRIO-9035

Is it possible for me to log data on the host computer opposed to on the controller itself? I'm needing to log quite a bit of data and I'm not wanting to use my storage on the cRIO. I'm using scan mode on the controller.
Thanks

Lots of ways to do this. You can write a datalogger to run on the PC, to read shared variables hosted on controller and write them to a file. There is also the DSC module for logging hundreds to thousands of shared variables to a database, if you need that.

Redesignating the Host Computer

Hello. Maybe these are simple questions, but I am not an expert, so here it goes.
1. I am replacing my host computer so I will need to redisignate the host computer on my network. Do I have to start over and set up the network again, or is there an easier way that will not affect the exisiting networked computers and devices?
2. My current host is hardwired to a WRT54GS router. I am replacing the existing hardwired desktop host with a laptop that will be wireless and the router and cable modem will be stand-alones. Are there any issues associated with this I should know about? Thanks!

1) Your WRT54GS does not care which computer is the host. All network computers are treated equally. I don't know whether or not Windows cares about this - I guess this depends on how you set things up in Windows. But this definitely is not a router problem. Might be a Windows problem.
2) The only issue with this setup is that whenever you change any of your router settings, you should connect to the router by wire. Do not try to change router settings wirelessly. Changing the router settings wirelessly usually works, but sometimes can cause serious router problems. And never ever try to upgrade the router's firmware wirelessly - this will likely kill your router.

HT1766 can i back up my ipad if the host computer has lost every thing?

Can I back up my ipad if the host computer has lost its operating system and the was re-instald?

Yes, this would be like syncing to a new computer. So, some precautions are required or you might lose what's currently on the iPad.
iTunes will only let you sync to one library at a time, if you get this warning message, follow this:

[SOLVED] VirtualBox: Arch Linux host unable to reach guest over NA...

Hello everyone,
I recently installed VirtualBox on my Arch Linux install to tinker with GitLab on a Debian VM. I've set up a standard VM running Debian (wheezy) and made sure it's network settings were set to "NAT". However, I am unable to ping or ssh to this VM (which is running an ssh server among other things). Where this gets a bit weirder is that I'm perfectly able to ping and ssh to my host machine (running Arch).
I installed the version of VirtualBox available on the official repos and I'm running on the default kernel too.
I've install VirutalBox by following the infos posted on the wiki. My current user is part of the vboxusers group :
% groups duane
disk lp wheel uucp locate rfkill games network video audio optical floppy storage scanner power users vboxusers
I've added the proper kernel modules to /etc/modules-load.d/virtualbox.conf so that they are loaded automatically on boot time :
vboxdrv
vboxnetadp
vboxnetflt
vboxpci
% lsmod | grep vbox
vboxpci 14581 0
vboxnetflt 17612 0
vboxnetadp 18355 0
vboxdrv 264794 5 vboxnetadp,vboxnetflt,vboxpci
I must also note that the net-tools package is installed.
Now, I get the ip adress of my host :
% ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

valid_lft forever preferred_lft forever
inet6 fe80::5eac:4cff:fe09:d3f3/64 scope link
valid_lft forever preferred_lft forever
Then I try to ping it from my Debian guest.
user@debian:~% ping 192.168.1.22 -c 3

And I try to ping my guest from my host :

--- 10.0.2.15 ping statistics ---

There. I hope I didn't give too much information.
I don't really understand what's going on there, usually that workfow works immediately in all the distributions I tried before, and on windows as well. I think I followed all the steps to make this work and yet it doesn't, and I'm not sure this problem is related to VirtualBox itself.
Thanks in advance for any tip or comment on that.

What I do for all my VB guest VM's is to set 2 network interfaces, one the normal (default) NAT, and the other a host-only interface. That way your guests are completely hidden from the local lan which may be desirable if e.g., your host is a laptop which you move around various places. The guests can access anything outbound and you can still ssh to them from the host (and also, using ssh ProxyCommand via that host if you want to access them remotely).

How do I change the host computer name?

Hello everyone...
I completely uninstalled 9iAS.
Restarted
Renamed Computer
Restarted
Reinstalled 9iAS without incident.
But...9iAS is still picking up the old computer name and I can't start any services.
I thought I did a complete uninstall:
Uninstalled with universal installer
Removed registry entries
Deleted all assoc. folders.
I don't mind reinstalling if I have to, but what did I miss?
Can anyone help me with this, we're at a standstill?
Thanks.
Lesley.

I forgot to change the stupid hosts file.
AAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH.

TS1369 How do you unlock your Ipod when you have exceeded your attempts to unlock it? I have tried connecting it to the host computer but the computer won't recognize the Ipod because it is locked.

[SOLVED] VirtualBox 4 & USB Host

I'm moving from Virtualbox 3.x (binary PUEL edition with USB from AUR) to 4.x. My 3.x was fully working including USB host.
I've uninstalled Vbox 3.x and installed the following packages:
- virtualbox 4.0.0-2
- virtualbox-additions 4.0.0-1
- virtualbox-ext-oracle 4.0.0-2
Extension pack shows up in Virtualbox extension manager (USB host). I've also installed guest additions and enabled USB host under VM's configuration. However I'm unable to select any of my USB devices (everything is grayed out). Is there any additional step to go through in order to get access to USB devices.
Thanks
Alphazo
PS: From my previous working 3.x installation I also have my user belonging to the vboxusers group and vboxdrv module loaded by rc.conf.

According to the wiki it is no longer required to mount usbfs by modifying /etc/fstab (although you need HAL to be running).. Again I had USB host working fine with VirtualBox 3 PUEL edition. I since moved to VirtualBox 4 (GPL) + extension pack for USB (PUEL) but can't get USB to work. I'm not sure the package virtualbox-sun can solve my problem.

Time Machine makes the Host Computer unusable

I have been running Time Machine for some time now. Long enough that it started notifying me that it was deleting older backups. Shortly thereafter my computer (24" IMac) started to run very slow. So slow that it would take several seconds to type a 4 letter word and the mouse movement delay was several seconds. I went to the control panel and turned Time Machine off. That did not help. So I next disconnected the firewire disk that is hosting the Time Machine backup and my computer returned to normal.
So what do I do now? For obvious reasons I am reluctant to reconnect the Time Machine disk. Any suggestions on what might have happened and/or how I can safely reinstate Time Machine?

Obviously you are running out of space on the backup drive causing TM delays as it combs through data to determine what can be deleted to make up the space. That would suggest you need a new, larger hard drive for TM backups - might consider doubling the size at the least.
To continue with the new drive you want to clone your old backup to the new drive so you will need enclosures for both drives.
Clone using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new backup drive.
Source means the old backup drive.
Be sure to prep the new drive as follows:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Be sure you only use Disk Utility or SuperDuper! to clone the TM backup correctly.

HT2688 When using either Music Sharing or Home Sharing, can I edit song star ratings on guest devices, or just on the host computer?

I'd love to be able to add song ratings to tracks regardless of which machine/device I listen with, but it seems I can't do that currently. I'm using the "Music Sharing" option described on this support article (HT2688), which allows me to view and listen to songs, but prevents rating them. Thanks for any suggestions!

Just connect the new iPod to your computer and setup the iPod via iTunes (instead of via wifi).

Screen sharing not exactly the same as the host computer's screen

Hi all
I am using a mac mini as a media server connected via HDMI to my big TV downstairs. I am using screen sharing from my macbook air to do little tasks while not downstairs. This has been a very good setup.
One thing I wanted to do is maintain my iphoto library - going through old albums, confirming faces, red-eye etc. whatever.
Using screen sharing works for this, mostly.
When I choose a photo and click "edit", my TV downstairs shows the photo fine, but my screen sharing on my laptop shows nothing but black where the photo should be. When I zoom in, I see the navigator window appear (with the image) but I do not see the photo itself. I am including a screenshot. Note how at the bottom, you can see images, and in the zoom window you can see that there is an image there, but the image field itself is empty. On my TV I can see the image (a squirrel, as it turns out).
Others I have talked to about this claim that some video sources do not "play well" with screen sharing and/or VNC. I haven't encountered these things but I do recall old versions of windows would only display a movie on one of two screens, even when the screens were mirrored (a big pain for presentations if I recall)
Hoping that this is a bug in screen sharing that apple can fix? anyone else have this problem? anyone else can try this and confirm?
The mac mini isn't running Lion yet but the macbook air is. Other than that all software etc is up to date.
I tried screen sharing on an older laptop running the same os as the mini (snow leopard) and the same thing happens, so it isn't a problem running between 10.6 and 10.7.

I saw similar problems. Please see my Aug 21 post on vnc at https://discussions.apple.com/thread/3267893

How to get the ip address of the host computer

Hi all,
How do I get the Internet IP Address of the Machine that has the Oracle HTTP Server?
Thanks.
Allen
Edited by: A.Sandiego on Sep 12, 2008 6:52 PM

Hello,
Do you mean the internal IP address or the IP address as seen by remote machines?
If you mean the internal IP address, then you can use -
OWA_UTIL.GET_CGI_ENV('SERVER_NAME');If you mean the internet accessible IP, then that's another kettle of fish, as due to your traffic routing etc, the server itself might not necessarily know that address, so if you really need to know it then you'd need to write a process that contacted a site like whatsmyip.org and parsed the output to find out the public IP address of that machine.
It really depends what you're trying to find really?
