When it comes to scalability, there is no obvious victor, with Hyper-V dominating in some capabilities while VMware benefits from others.
What is better VMware or VirtualBox?
Workstation/Fusion is unquestionably the better choice if you already work in a VMware environment because it has better compatibility with VMware servers and data management tools. Overall, it’s probably a better choice for commercial use. Virtual machines made with VMware run more quickly than those made with VirtualBox.
Can virtual machines infect their host?
It’s highly unlikely that OS-es that pose security risks will use them as sandboxes. However, the shared clipboard is most likely the security risk that is ignored the most. Of course, this functions even with a disabled network. Unintentionally or not, copying an entire infected file increases the risk of infecting the host operating system.
What are the security risks with virtualization?
Top virtualization security issues
- external assaults
- keeping VM snapshots.
