Is a virtual machine secure?

What is type1 hypervisor?
Type 1 Hypervisor. A bare-metal hypervisor (Type 1) is a layer of software we install directly on top of a physical server and its underlying hardware. There is no software or any operating system in between, hence the name bare-metal hypervisor. … Type 1 hypervisors are mainly found in enterprise environments.
Do virtual machines need antivirus?

Are virtual machines slower?
Quick answer: every time you virtualize something, you get penalty over running it on the bare hardware. That means that the OS running in virtual machine will run slower than if it would run directly on that same machine without virtualization layer.
What are the disadvantages of virtual machines?
Disadvantages: Virtual machines are less efficient than real machines because they access the hardware indirectly. Running software on top of the host operating system means that it will have to request access to the hardware from the host. That will slow the usability.
Do virtual machines have their own IP?
Whether you are using host-only, network address translation (NAT), or bridged networking, each virtual machine must be assigned an IP address. For host-only networking, the host must also be assigned an IP address.
Can Ram have a virus?
RAM Virus Infection Technically, viruses cannot infect RAM because RAM clears itself every time a computer starts up. However, viruses may infect the RAM when they run, bogging down the computer and rendering the RAM ineffective. Some viruses avoid RAM completely and interact with the operating system or hard drive.
