Disclosure: My company does not have a business relationship with this vendor other than being a customer.
We have found VSX solutions to have lot of issues in our customers networks... Also hard troubleshooting and some anomalies are common. More than one customer feel safer with phisical Check Point appliances rather than VSX and decided to roll-back after some time of use (12 months of production). I can't raccomend this product, if you're looking to firewall instance virtualization, look further and you can find more mature solutions.
