android ubuntu 64bit
I installed Ubuntu 14.04 64 bit and now I can’t start any of my old Android Projects neither from Android Studio nor from the ADT Eclipse Bundle. Even a clean newly created project in either of these two IDEs fails to load on my phone (I did not change anything on the phone). The log from logcat just loops endlessly the following stuff, which I think in essence says “VM aborting” and “A/libc Fatal signal 11 (SIGSEGV)” and a warning “JNI WARNING: input is not valid Modified UTF-8: illegal continu

virtualization hypervisor
Modern hardware-assisted desktop virtualization products (like VMWare Workstation or VirtualBox) normally provide the guest OS with a virtual graphics adapter that has a limited functionality.Is it possible to switch the adapters, i.e provide guest OS with direct access to the real graphics adapter, and assign a virtual graphics adapter to the host OS? Is there any software that has this functionality? If not, is it possible to develop such system? Let’s assume we only have a single guest OS.

windows-7 virtualbox partitioning virtualization xubuntu
Background: I am using VirtualBox installed on Windows 7. From within VirtualBox I am using Xubuntu as a virtual OS. The reason I chose this approach is so that I don’t have to keep turning off Windows and rebooting from Xubuntu every time I needed to switch OSes. And VirtualBox’s seamless mode is pretty amazing to allow me see Xubuntu and Windows 7 all in one screen. Issue: Now I am thinking of a way to have Xubuntu more integrated into my system.

virtualization
This is a hard question to ask as I know very little about this topic. Please bear with me.From my perspective, supporting a relatively small number of machines, the notion of virtualization has one intriguing benefit: hardware independence. Perhaps that’s not the right way of saying it, but I really like the idea of being able to take an entire machine and move it to any adequate piece of hardware.I know this is possible, of course, but things seem to get tricky when it comes to virtual disks

So I was having a problem with my hard disk (I think). Everytime I ran git log commands (when running Windows through VMWare Fusion for Mac) it would throw a fatal error causing VMWare to crash (something about unable to reach disk drive). Even if I booted to Boot Camp natively and tried running git log, I got some error about less.exe failing.I couldn’t copy/delete any files in the git/bin folder without problems (VMWare crashing). So I tried to just install the latest git (1.6.7 from 1.6.4)
