From what I remember of the intel advisory that remixedcat posted, it effects hyperV, virtualbox and nearly every other VM system except vmware.
VMWare isn't immune from host->VM viruses, however: https://blogs.vmware...on-windows.html

NO! People assume a sandbox protects them well NO! IT DOES NOT!
Sandbox ,which protect your host from virus.A sandbox is use for separating two programs , so that one cannot affect the other. It's a form of security for when there is uncertainty of one program's effect on the other.

What? You're thinking of trojans, viruses don't need internet/network connections to operate.
Ok... I got your point..
If virtual machine has no network for access to your host,your host won't get affect by any virus in your guest operating system.

No it's not true, viruses can exploit sandbox/VM things which is why recently as I said on the other page that hyperV, virtualbox, and all the other large-scale VM solutions with the exception of VMware had an exploit leaked that will pass from the guest to the host no problem. You've also got bugs in CPUs that can allow exploits too.
His point was that if the guest can not access host via network, then its not possible to jump from guest to host. Which is true - guest unless setup has no access to host file system, so if no network access it should not be possible for infection to jump from guest to host.
Unless person with access to host filesystem exe something off guest file system.
