I want to feed packets from a mirrored (SPAN) port of Ethernet switch to two monitoring devices at the same time, hence both the monitoring devices gets exact same set of packets.

I can think of using a simple Hub to which the two monitoring devices and the mirror-port of the Switch are connected, but this becomes expensive.
I may need packets from same set of source ports to be copied to multiple destination mirror (SPAN) ports. I am using a Cisco managed switch which gives me option to chose only one destination port and multiple source ports.
Are there any other ways to achieve this?, or can I configure a Switch to choose multiple SPAN ports?.

required disk size is more than 8GB

But got only 2GB

In GNS3 I imported securityonion-16.04.6.1.iso image as new qemu vm, not as existing qemu vm. These is no where an option to change/choose enough disk size, the only option I got is to select RAM size and number of CPU-cores. But the disk size assigned to the VM is just 2 GB, which is not sufficient to install the complete image.

Alternatively, I installed qemu on my host machine, and there I can choose the disk size, ram and number of cores. So the os image installed perfectly. Now I tried importing the VM as existing qemu vm on GNS3. But I could not see it listed.

How can I increase the disk size so that I can complete the installation of securityonion OS on GNS3

Operating System: linux ubuntu 18.04
GNS3 Software Version: GNS3 2.1.18
