Thanks for your comment, but nope, this is something that I cannot accept even one bit. The VM is qemu and works flawlessly with all distros I have tried (around 20). Also the damn installer crashes, not the OS. It crashes and I have to double click on the app icon to open it from the live disk. The only time I can accept suspecting VM is when:
1. More than one installer fail
2. The whole live disk gets unresponsive or crashes.
