Ubuntu :: Slow Boot Time After Creating Virtual Disk For Virtualbox Guest

Jun 4, 2010

My laptop boot up time increased considerably (10 seconds) after allocating a virtual drive for virtualbox guest. The guest installation did not work so i removed it along with the virtual disk. Now everytime when i boot to ubuntu, after inputting my password in the login screen, it takes much longer to load the system. And during the loading time the disk activity indicator light blinks indicating the harddisk is actually busy loading the system.

I decided to search around for a possible answer and force reprofiling ureadahead does the trick Now boot time is back to what it used to be

General :: Windows XP Running As Guest On VirtualBox Is Very Slow

Aug 9, 2011

We had an old Windows XP server running a Filemaker database on a 2.6 GHz Intel CPU, but that server died. It's been replaced by a box with two 2.4 GHz Xeon CPUs and 5 GB of RAM that's running Ubuntu 11.04 natively, and Windows is running as a VirtualBox guest. 2GB of RAM has been dedicated to the Windows guest.Of course, these old Xeon CPUs don't have the VT-x extensions, so I wouldn't expect to be able to add CPUs to the VirtualBox guest, but the Filemaker database is running at least 2-3x slower than it did on the old server. I would expect that utilizing one 2.4GHz CPU out of four available shouldn't result in such an astounding difference.

I would also like to be able to continue using this setup, since it would also mean we'd be able to remove our Linux server from the rack, which is running on even slower hardware (not that the system requirements are high for its job though).So my question is: Why is this so slow? Is there anything I can do to change the situation? Or should I just give up now and find more suitable hardware?I understand that the "new" machine should be about 1% slower in theory, so please don't tell me this "should" be fine. I need more concrete answers (as in, "I've tried this before and you should do X") since in the real world, it appears to be about 50% slower. I'm about to blame "virtual" CPUs to multithreading on single core processors, and possibly the difference in CPU architecture between Xeon and Pentium 4 CPUs.

Fedora :: Slow Boot Time 12 / Cannot See Partition On 500 GB Disk, But Still Boots Up?

Mar 4, 2010

I'm using Fedora 12 since 2 years lately, I really enjoy this S.O., it's quite robust and wonderful, but a couple of months ago it is really slow to boot up when startup the computer, I've checked everything, but seems to be ok, I had a partition lost arround that date, but recover successfully, it happens when I run gparted that It cannot see partition on my 500 GB disk, but still boots up. When running Mandriva live cd, it can see (?) all partitions on that disk, even with Fedora Dolphin I can access this partitions. What could it be?

Server :: Disk Dump - Creating Virtual Directory

Apr 14, 2010

I'm quite new to linux, but I've managed to grasp some basics. Now my intention here to create a virtual directory, which I resorted to creating an Image File so that I can mount it and have my folder have a dedicated storage. I will mount this image as a loop device. Well it's not much of a problem, but I would like to know whether this is suitable. Say I want to create a 25GB Image.

Code:
dd if=/dev/zero of=/home/disk-img/25GB.ext3 bs=1G count=25

Is this recommended? I'm using block size as 1G which is really huge, so I was wondering, if this is actually recommended. From what I read, some said that it's only advisable to use 4096k or lower, but what I found was that these suggestions are very dated (year 2003), and it is now 2010, so I would like to know if it makes any big differences.

Fedora Servers :: Unable A Virtualbox Guest To Start At Boot?

Mar 27, 2010

Can anyone help me with how to create an init.d script that will startup a vm machine in virtualbox at boot? I found this script:[URL]..But it is for ubuntu. I am running fedora 12 x386 and using it as an Amahi server. Very cool, but it would be extra cool if I had a virtual windows machine startup when I booted up this server. Then I could just rdp into it when I needed something in windows.

OpenSUSE :: Virtualbox Guest Additions: Set A Shared Folder In 11.2 Guest

Mar 4, 2010

OpenSUSE installed in a Virtualbox Virtual Machine and I want to set a shared folder.

1 - Set up a Virtual Machine and install OpenSUSE 11.2

2 - Create a shared folder on host (HostFolder)

3 - Setup the shared folder in Virtualbox Via the Virtual Machine details or via Devices > Shared Folders...

4 - Install dependencies for running the Virtualbox installer You need to install the right development kernelpackage for your machinetype (use 'zypper search -i kernel' to see what's installed) sudo zypper make gcc kernel-source kernel-hosttype/default-devel

5 - Run the Virtual Machine and go to Devices > Guest Additions This mounts an iso image in your OpenSUSE guest.

6 - Open a root terminal and run

cd /usr/src/linux
make oldconfig && make prepare && make scripts && make dep
cp ../linux-obj/$HOSTTYPE/default/Module.symvers .
make prepare

* A commenter on previously mentioned thread says this step is unnecessary but it doesn't work without on my system. I suggest trying step 7 first and returning to step 6 if that fails. *

7 - Run ./VirtualboxLinux yourhosttype .run from the mounted iso image.

8 - Create shared folder in OpenSUSE (GuestFolder)

9 - Test with sudo mount -t vboxsf HostFolder /home/user/GuestFolder It works? Great! Let's set up the system so it automounts for your regular useraccount instead of root-only access.

10 - Add this line to /etc/fstab HostFolder /home/user/GuestFolder vboxsf defaults,uid=1000,gid=1000 0 0

11 - It works for me but if it still doesn't automount after a reboot; sudo mount -a

Fedora :: Installing Guest Additions Virtualbox 13 Guest?

Jun 3, 2010

I had a lot of trouble installing Guest Additions within the Fedora 13 Guest on a Linux host. I had to mount the vboxGuestadditions.iso from the Device --> CD/DVD Devices menu. Then I located the appropriate package for my system. In my case it was the AMD64 Linux version.I ran this as administrator in Terminal. I used the "bash" command followed by the package name. This was after CDing the the appropriate directory. The packaged installed, I then rebooted and it worked fine. (Something that would make this easier is to load a script into nautilus that would allow me to open a locatation as administartor at the open window. I'm sure there is something in Fedora to do this but I couldn't find it in a hurry so I used the command line way).

Ubuntu :: VirtualBox 3.1.8 - Virtual Machine Hangs During Boot?

May 13, 2010

I recently installed VirtualBox 3.1.8 r61349 from the deb file virtualbox- .1_3.1.8-61349~Ubuntu~lucid_amd64.deb onto a recent clean install of Lucid Lynx on my HP p6210f (6144 MB RAM, AMD Athlon II X4 620 CPU). I then imported a friend's VM and tried to boot it. The VM consistently hangs with the following showing on the console (this is the last 3 lines, for context):

NetLabel: protocols = UNLABELED CIPSOv4
NetLabel: unlabeled traffic allowed by default
NET: Registered protocol family 2

I thought initially it was a problem with my friend's VM, so I decided to create a new VM from scratch, and boot from a CentOS-5.4-i386-DVD instead, which I have done before with previous versions of VirtualBox. When I do that, I'm able to select my installation method (so I know it's booting from the CentOS ISO), and then it hangs at exactly the same point. I couldn't find any other mention of this problem, but it's a pretty recent release of VirtualBox - I think just days old.

The VM: OS Type=RedHat (presumed 32-bit), 1 processor, 1024 MB RAM

Ubuntu :: Very Slow Boot Time On AMD 30m / USB Hardware Doesn't Work After Computer Boot?

Mar 21, 2011

I've been a long time Windows user, but I've started a small firm and because of lack of funds, I've decided to install Ubuntu on my company's PCs.I have 8 PCs in total - 6 of them with Intel CPUs, and the last two with AMD CPUs. I bought the extra two computers because I've managed to find an extra two people to work at my company, and AMD-based PCs are cheaper so I've decided to buy them instead of Intel.Long-story short, I've installed Ubuntu 9.10 and boot time takes about half-an-hour. After the computers finally boot, USB hardware doesn't work at all. I was forced to buy PS/2 keyboards & mice and they both work fine after the PCs boot.I don't know what's causing this delay.I've enabled Cool 'n Quiet from BIOS.I've tried several instructions like editing the /etc/modules file.I've installed cpufreqd, tried to configure it, but it didn't work.I've check the CPU stats and my CPUs are running at 800MHz. I can't believe nobody managed to fix the 800MHz problem as I've noticed it's quite common among AMD Ubuntu users. I think I've tried almost anything that I've found on this forum.I can't keep asking my employees not to reboot their PCs. Both Chrome/Firefox crash a lot on Ubuntu so they're forced to restart their computers.The computer specs are: AMD Athlon II X2 240 dual-core @ 2.800MHz, 2GB RAM, 500GB HDD, etc.

Ubuntu :: Slow Boot Time - Boot To Bios And Then The Screen Goes Black With A Blinking Cursor

Oct 14, 2010

I've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.

I have the file, I just need instructions on how to create a bootable dos disk using a USB pendrive.

OpenSUSE Install :: 11.2 - Incredibly Slow HDD And Boot Time Increased

Mar 30, 2011

My hardware:
AMD Athlon X2 4800+ (2,5 GHz) + 2 GB DDR2 memory
MSI K9N V2 (nforce 520)
SAMSUNG HD250HJ (SATA, 250 GB)

I'm using OpenSUSE 11.2 with all the released updates are installed. I've got an Windows Xp SP3 on the same hard drive and it's works fine. S.M.A.R.T. says the hdd is 100%. A few days ago I realized that the boot time increased and the hard drive operations takes way too much time. So currently the boot sequence takes 11-14 minutes.

I've already tried to solve this problem but no effect:
1.) cleaned up the root directory to create more free space
2.) plugged the sata cable to another port
3.) changed from AHCI to IDE and reverse in BIOS settings
4.) added ahci, sata_nv into the /etc/sysconfig/kernel file and created a new initrd
5.) searched for problems in the syslog
Just to imagine how slow is currently the system/hdd:

Ubuntu :: VirtualBox 3.18, XP Guest, No Printers?

May 11, 2010

I'm using the newest VB 3.18 Lucid AMD64 .deb downloaded from Sun. Previous versions have not had USB support in Lucid. Now, when I start the XP guest, all my USB devices seem to be detected. My USB phone is shown as 'busy' as is my mouse. However, both my printers remain greyed out and are shown as being 'unavailable'. I have tried manually adding the printer filters before starting the guest, but no dice. Is anyone else having this problem? Any ideas as to a possible cause?

Ubuntu :: Turn Off Guest OS In Virtualbox

Mar 8, 2011

in my opinion, it's wrong to turn off the operating system by pushing the power off button on the hardware directly but is it okay to do that in the Virtual Machine I am running Windows XP on VirtualBox sometimes I feels lazy to wait for windows to shut down so I just close the window that runs the guest OS will that do any harm to the host system? or the guest system itself? If I saved all the files that is important, I couldn't think of any side effect.

General :: Cannot Ssh Into Ubuntu Guest On Virtualbox 4.0.4 On Windows 7

May 15, 2011

I have an Ubuntu guest installed on Virtualbox 4.0.4 running on Windows 7 Home Premium. I have two firewall rules for Vbox which allow any, any inbound for both TCP and UDP and those rules have edge traversal enabled. I have host ports 9080 and 9022 forwarded to 80 and 22 on the guest. The Win7 box is on an Ethernet connection

After some testing, I have a netbook with a Wifi connection and Ubuntu netbook remix which cannot make an ssh connection to the Ubuntu guest.

But, the same netbook can telnet to port 9080 on the Win7 machine's address and successfully connect to a web server running on port 80 of the Ubuntu guest.

In order to check this out, I ran initctl stop ssh on the Ubuntu guest, verified thagt port 22 had no listeners, and ran ssh with /usr/sbin/sshd -d -e. This shows various bits of debug info from the console. Then I ran Putty on the win7 machine to connect to port 9022 on it's own IP address (that it got from DHCP) and made a successful connection to the guest Ubuntu.

The variable that I don't know much about is the landlord's cable router setup, but I can't figure out why that would block packets to 9022 but not packets to 9080.

Ubuntu :: Using Multiple Monitors With Guest In VirtualBox

Nov 30, 2010

I'm running Ubuntu 10.10 x64 as a guest in VirtualBox on top of Windows 7. I recently bought a second monitor, and I want to set up my Ubuntu guest to use both monitors. I configured VirtualBox to give two displays to the VM, and two windows are displayed when I run the VM, however, the Ubuntu guest only uses the primary screen and does nothing with the second--the second screen is just black.

When I go to the monitor settings, only the one monitor is detected (as an "unknown monitor") I have the latest guest additions installed and the driver under System-Administration->Additional Drivers is shown as installed and working correctly. I don't have any issues with the single display--it shows in the correct resolution, and works fine if I set it to fullscreen or seamless mode. Any thoughts on getting Ubuntu to detect the other screen?

Ubuntu :: How To Stop Disk Check Every Time On Boot Up

Every time I boot up I have to go through a disk check and then restart, how do I stop it from happening? When the disk checks happening I press escape and it usually says its deleted inode something because it has zero Dtime or some thing similar and also a paragraph of repeated lines saying something like all system files need alsa base.cnfg it will be ignored in a future release then the disk check completes and it restarts and is fine then, also sometimes it says dev/sda5 (my ubuntu partition) was not cleanly unmounted check forces. Is their a way to stop this happening as it ends up taking ages just to login.
