Install GNS3 remote server on ProxMox (2022)

** Update 4/25/22 **
There is a known issue with ProxMox 7.1 preventing qemu images from running with this instillation method. There are two current solutions:
1) Solution from @Munandar Addin, Downgrading the host to ProxMox 7.0 appears to resolve this problem.
2) Solution from @Skulltrail, You have to install the latest 5.15 kernel and update Ubuntu to 21.10. Once you've done that and remove the LTS checks in the gns3-remote-install.sh script at the very top, you can continue installation and qemu VMs work as expected.

In this video we will be installing a GNS3 remote server on a ProxMox host.
