Yes, unlike the Vx310, and it's the same cutoff point as the physical line. To enable it, the virtual machine needs a minimum of 8 GB of RAM allocated, on top of the base resource requirements.

4 CPU cores and 8 to 16 GB of RAM, plus roughly 200 GB of direct-attached disk space. Network-attached storage isn't supported.

VMware ESXi, Microsoft Hyper-V, Citrix XenServer, and Oracle VirtualBox. It's built for on-premises virtualization rather than public cloud platforms.

Concurrent user capacity matches at up to 800 users, but throughput on the virtual edition tops out lower since it shares resources with the host rather than running on dedicated hardware. There's also no Ethernet bridge; it deploys through your hypervisor's virtual network instead.

Yes, as a separate add-on subscription, the same as the physical line. It runs suspicious files through full system emulation and checks them against Barracuda's global threat intelligence.
