How does the latest Intel flaw relate to CentOS 6.x systems that run under VirtualBox hosted on Windows 7 computers? Given the virtual machine degree of separation from the hardware, can this issue actually be detected and exploited in the operating systems that run virtually?  If there is a slow down associated with the fix, how much might it impact the virtual systems?

  • Supposedly a virtual machine can detect and leak out in various ways. Both Xen and qemu are working through patches to deal with this. Other virtual software vendors are probably working on this also. I am not sure why the patches to the operating system do not stop this but it seems to do with how the modern CPU does virtualization which makes the Windows 7 patches not applicable.
