VM-100 maximum number of interfaces on KVM

For some reason, after activating the license on VM-100, I still only see 8 interfaces even though I have interfaces configured in the VM settings.

I thought KVM supports up to 25 interfaces.

This is running on KVM on Ubuntu LTS 20.04

@LCMember2099,

25 total interfaces with 24 actually usable for the dataplane, the first interface assigned is the management interface. Judging by what you're reporting I would make sure that you have the interfaces set to e1000 or virtio drivers and not the default rtl8139 driver.

I have 13 vNICs all configured as virtio. Brand new VM setup licensed. Same issue.
