Ubuntu Servers :: 10.04 Server Virtual Terminal / Display Not Working

May 4, 2010

Clean install of 10.04 Server 32 bit.Only services OpenSSH Server and Print Server.Machine boots and can be accessed through ssh.Virtual terminals (cntl-alt-1,2,3,4,... do not result in video to the monitor (no sync) or a display.If I type blind, I can log in, ssh back to my other machine, and create a file. So the virtual terminal is there and listening to the keyboard and running, just not creating a display.

This machine has been working fine with 08.10 for quite time up until yesterday, so I don't believe it is a hardware problem.Any ideas why the video on the virtual terminals would not work?

Ubuntu :: Separate Virtual Host To List And Display All Contents In /var/lib/php5?

Apr 3, 2011

I have an ubuntu 8.04 server running a couple of web sites using virtual hosts , apache2, mysql and php. I have noticed that by default php sessions are created in /var/lib/php5 and all stored in plain text.

I have quickly created a php script in a separate virtual host to list and display all contents in /var/lib/php5 , and it seems incredibly easy to see what details the other accounts are storing in sessions.

Ubuntu Multimedia :: Create Virtual Drive From Cd Folders ?

Apr 11, 2010

I have one cd program, but the cd is corrupted (tried to make backup copy in windows xp with alcohol 52%, but got error at about 95%, and i can not use this cd any more in xp - only for few minutes, then it stops...)

I made few days ago one .iso image, but without cd drive i can not run it (has copyright protection).

The only thing i can do now is to copy cd data. But can i make from this cd folder some virtual cd image in ubuntu, which i could transform into .iso image (using alcohol 52% in xp to avoid copy protection and enable to use it without cd drive)?

Ubuntu Servers :: Create A Virtual Host For A Php Project?

Apr 28, 2011

I needed to create a virtual host for a php project I'm working on. Rather than using command line and text editors, I installed webmin to accomplish this and hopefully perform other server configuration in the future. When I created the virtual host and tried applying the changes Apache wouldn't re-start, and still doesn't restart after complete re-boot. It's getting hung up at the end of apache2.conf, which is trying to include /etc/apache2/sites-enabled/000-default.

When I look at 000-default from a File Browser, it's a linked file to etc/apache2/sites-available/default I can open both the linked file and actual file in a text editor, and it looks fine. When I view the directory, /etc/apache2/sites-available from shell, the default file isn't visible. It seems this "invisibility" is probably related to the error, which is preventing start-up. Can anyone explain why the file would be visible from the Ubuntu File Browser GUI but not from the terminal, and how I can fix so apache can recognize this on start-up?

Fedora Hardware :: Multiple Display Drivers For Virtual Machine?

Feb 25, 2010

I have a MacBookPro5,1 system that can boot into Fedora 12 x64 as well as Mac OS X. My installation of Fedora is set to use the nVidia graphics drivers to provide 3D acceleration when running the operating system natively. I have installed VMware Fusion on Mac OS X, and I can use it to boot my installation of Fedora into a virtual machine. However Fedora refuses to go into X Windows and just sits there with a blank screen. I can use Ctrl+F2 to switch to a command line and log into the system through the command line interface.

I'm not exactly sure why this is happening. However, I suspect that it is because when the system runs virtually, it does not make use of the nVidia graphics card. Instead VMware Fusion provides a virtual VMware SVGA 3D adapter. What would it take so that Fedora would use a driver that is compatible with this virtual display adapter when running in a virtual machine, and then use the nVidia driver when the system boots natively?

I tried changing the resolutions, and it does not make a difference. I tried rebooting and the display is still bad.

OpenSUSE :: Cannot Create A New Virtual Machine In Xen

Jan 5, 2010

I have been unable to create any type of Windows VM in Xen. Every time it tells me that the processor(s) in the machine do not support full virtualization. After some research, I found several articles regarding the vmx setting in /proc/cpuinfo not showing up when the xen kernel is booted versus it showing up in the default kernel. Of course, I am not seeing the vmx extension in /proc/cpuinfo after I boot to the xen kernel. In the other posts where other people are in the same situation, the only resolution is to upgrade to the 2.6.16 xen kernel. I am already past that:

linux-vxke:~ # uname -r
2.6.31.8-0.1-xen

yet I am still unable to create any form of Windows VM. I have even seen that some people are able to create a partially virtualized Windows VM, and they report that the message is only a warning. However, I am unable to get past this message. I am running a Dell Optiplex 760 with an Intel Core 2 Duo E7300, and I have the VT-x setting enabled in the BIOS. Has anyone else seen this situation or have any thoughts on why this is happening?

Programming :: How To Create Own Virtual Device

Hardware :: Video Display Goes Blank When Switching From X To Virtual Console / Sort It?

Nov 9, 2010

I am having a problem getting my virtual console back after starting XWindows. The display goes blank when I press Ctrl-Alt-F1. If I press Ctrl-Alt-F7 I get the X session back. I have tried setting vga=x31A on the linux boot up. Also tried rdev -v /vmlinuz -1, and rebooted. I have tried two different monitors, same problem. One is a an LCD (Philips 170S6Fb/27, the other a Samsung Sync Master 750s. Originally the Samsung worked fine. I could switch between X and VC no problem. Now that I have the LCD monitor working after changing the XF86Config, I have this problem.

My kernel is 2.2.15-5.0, Redhat 6.2. Here is the output of lspci for the video card:

00:0c.0 VGA compatible controller: ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB] (rev 9a) (prog-if 00 [VGA])
Subsystem: ATI Technologies Inc: Unknown device 4755
Flags: bus master, stepping, medium devsel, latency 0
Memory at e2000000 (32-bit, prefetchable)
I/O ports at b400
Memory at e0000000 (32-bit, non-prefetchable)
Expansion ROM at 000c0000 [disabled]

Hopefully there is someway to control how linux sets the video mode when switching consoles.

Fedora :: Can't Create Virtual Machine With QEMU/KVM

Nov 8, 2010

I just install QEMU and virtual machine manager to use virtualization, but virt-manager cannot run properly. I can create a VM, then mount CDROM ISO, startup. With Windows installation, it runs well until format partition step, after that it is disconected and exit with error related to VNC. I dont know why have this problem cause the packages that I installed is from Fedora repo and I think they have been tested.

Here are some infos:

Fedora 14 - kernel 2.6.35.6-45.fc14.i686.PAE
qemu-2:0.13.0-0.7.rc1.fc14.i686
libvirt-0.8.3-2.fc14.i686

General :: Create A Virtual Serial / COM Port?

Mar 25, 2010

I'm currently working on a project for university that requires communication, via an RS232 link between a piece of hardware (I have designed and am currently testing) and some software(which need testing).

I was hoping to have my hardware finished by now so I could get on with testing the software over Easter.

The hardware does not work yet but I would still like to test the software.

Does any one know if there a way to make a virtual serial port that I could put data on and read data off while my program accesses it as a regular serial port so I can check my code?

I am using Ubuntu 9.10 and am happy to give any more information on request.

Ubuntu Networking :: Create A New Virtual Network Using A Subnet Of Public Range

Jan 27, 2010

There seems to be a lot written about virtual networking but I am not sure what approach to take in my situation. My local subnet has a public block of 128 addresses. I have a virtual host running on my machine. My machine has a static address and I'd need to assign one to the guest. I have edited the guest's interface file and assigned a public address to it's eth0. However the guest cannot ping out and I can't ping in.

By default the virtual machine manager creates a virtual network (virbr0) and assigned a private address range to it. I have tried to create a new virtual network using a subnet of my public range (/31) but the manager says the range must to a minimum of 16 addresses (/4). It doesn't look possible to achieve my aims using the virtual machine manager.

In the past I have used the procedure laid out here:[URL].. which is to manually create a bridge. I am not sure that is relevant for my 9.10. I think I would have to disable the network manager if I were to do that and I am not sure how to do that.

Ubuntu :: Create A Virtual Machine And Configure The System Through The GUI And Then Dump All Of The Settings?

I'm working on a script. fter it has installed and removed packages, I need to configure a ton of settings. In GNOME, I understand that those settings are kept in "/home/user/.gconf". Can I create a virtual machine and configure the system through the GUI to my liking and then dump all of the settings, so that I can load them on another machine? Is it as simple as copying the directories?

Ubuntu :: Create A Virtual Directory In Apache For One Of Company's Internal Websites?

Feb 22, 2011

I have a need to create a virtual directory in Apache for one of my company's internal websites. I have confirmed that I can create an alias for a local directory: Alias /vdir/ "/usr/share/somefolder/"

So I would get to this virtual directory by going to http://server.domain.com/vdir/. But when I attempt to point it to a shared folder on another server:

Alias /vdir/ "//servername/share/"
or
Alias /vdir/ "//servername/share/somefolder/"

Both return the 404 Not Found error, which I would expect if it is not connecting to the share. I've searched but can't seem to find the correct syntax and I know I am missing something basic. I have searched google and these forums but can't seem to locate the exact syntax. Are there other lines in the config file I need? Permissions should be no problem the shared is EVERYONE has access (for now).

General :: How To Create Virtual Folders From Saved Search

Jan 14, 2011

I would like to have on unix-like platforms, the same functionality as to Windows 7 Library folders (aka virtual folders) you see in Windows Explorer.Gnome Nautilus do that kind of virtual folders through saved search. But I want a system-wide solution, not a gnome-wide solution.Is there a tool that creates virtual folders from the concatenation of multiple search queries (the result of multiple find commands ?). The solution should index files for better performances and you should be able to define the default folder for copy operations.
