Cannot boot installed RHEL 7.1 with extlinux (syslinux) - linux

bootloader --location=mbr --append="console=ttyS0" --extlinux
in kickstart config file. The installation is made on virtual machine QEMU KVM.
No DEFAULT or UI configuration Directive found!

that error tells you that the syslinux configuration file does not define a DEFAULT action neither the UI (i.e. vesamenu) used for displaying a menu.

I can not access my ubuntu in dual boot mode

I had installed ubuntu 18 in my acer aspire. Then i installed windows 10 in dual boot mode. After installing the windows i can not access the ubuntu. The grub loader is not shown.
And there is no way to access my ubuntu.
I even tried to change the path of bootloader to ubuntu in cmd.
But no success. Please help me out.

"YOUR COMPUTER BOOTS DIRECTLY TO WINDOWS
This is a common problem and if you do not get a GRUB menu , re-installing or repairing grub will NOT HELP
Every BIOS is different, it might look like one of the following pictures:
UEFI 1
UEFI 2
Notice the "UEFI Boot Option Priority" or "Boot Option Menu" . Usually Windows is the default and Ubuntu (or as in the second picture elementary OS) will be an option.
Once you select Ubuntu on the UEFI boot menu you will then get a grub menu. You should be able to boot either Ubuntu or Windows from the grub menu.
Another issue that could make the system boot directly to Windows (without even showing the GRUB menu) is if either Windows took hold of the boot manager or after installing Ubuntu, the EFI partition was not properly configured for Windows. To solve this, simply go to Windows and open a terminal, then type the following (Need Administrative Privileges):
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi This will configure the Windows Boot Manager to take into consideration the GRUB Boot Manager. This could still happen even after running the Boot Repair from within Ubuntu. So making sure that Windows reads the Ubuntu EFI partition will solve it."

Using jsvc on aix 64-Bit

After modifying the configure script to add support for AIX6 and changing CFLGAS to add CPU type as PPC64 & adding -maix64 flags I am able to compile apache-commons on AIX6 machine in 64-Bit mode using gcc and IBM JDK 7.
But, i am unable to run jsvc to start any service or tomcat as service. I tried to set LIBPATH to include all JVM library locations and did not see any progress.
Below is the error i observed when running jsvc in debug mode.

This problem is solved by changing the commons-daemon source code. File "location.c" holds search path of JVM library for all operating systems. I added case for AIX in code with JVM library paths and recompiled code. This solved my problem.

Installing Ubuntu on Oracle VM Virtual Box: Failed to open the optical disk file

I need to install Ubuntu 64-bit on Windows 7 64-bit using Oracle VM Virtual Box.
I downloaded Ubuntu Desktop iso file, opened the settings of VM and selected the disk image of Ubuntu.
After this the following error message appears. How to solve this issue?
UPDATE: I tried both 34-bit and 64-bit Ubunto. Both fail.
Either your ISO is broken or you selected the wrong OS when creating the virtual machine. Try to redownload the file from the Ubuntu home page and mount it again.
You can follow the steps from here. Eventhough its for Ubuntu 14.04, the steps will not change.

Installing a .bundle file in Fedora linux

So I am using Ozone OS which is basically just fedora with a cool theme, and a lot less crap installed. I tried installing VMWare Horizon view client from here: https://my.vmware.com/web/vmware/details?downloadGroup=VIEWCLIENTS_LINUX_32&productId=421&rPId=7320
and then i renamed the file to vmware.bundle, when i make it runnable with:
chmod +x vmware.bundle
i ran the file using:
./vmware.bundle
this is what happens in my terminal
VMWare Horizon Client is an x86 application but you are trying to install it to an x64 Linux.
To run this installation, you may need to install 32-bit runtime libraries. Do you want to proceed? (yes/no)yes
Extracting VMware Installer...done.
but when i try going to the application menu, I can find VMware anywhere
There is really no such thing as ".bundle" files on Fedora. The only format for installable software on Fedora are RPM files.
All that this ".bundle" file appears to be, is the vendor's custom installation script, that's all. It's not any kind of a standard packaging format, of any kind.
You will be able to find a newly-installed application on your application menu only if the application correctly installed a .desktop file in the right location. If this installation script did not do so, you won't get anything in the application menu.
It is the application script's responsibility to install a .desktop file in order for the application to appear in the application menu.
try running /bin/vmware
that is the default install location

Unable to Install Maven plugin in Eclipse inside VMWare

I am trying to install maven plugin n eclipse helios. I am doing this setup inside VMWare Linux setup.
I am trying to install the software by providing this url..
http://m2eclipse.sonatype.org/sites/m2e
The eclipse progress bar shows "Fetching Maven Children ( 0%) ".
It doesn't go any further than that..
I tried the same by installing eclipse on the windows environment and it worked fine.
Any suggestions on what could be wrong with my eclipse and VMWare linux setup.
The network connections are fine,I am able to connect to the internet using the firefox browser in my VMWare linux setup. I have applied the same proxy setting to eclipse network settings .
Thanks
Yogi
You might need to set the proxy settings for Maven separately from Eclipse. Have a look here http://docs.codehaus.org/display/MAVENUSER/Using+Maven+in+a+corporate+environment
