Veeam incorrectly displays portgroups in Virtual Lab -> Settings -> Isolated Networks and when trying to add such a port group the following message box is displayed:
Шt is a known VMware SDK limitation where special characters are not escaped when used in names of vSphere entities such as port groups. It might still be possible to add that port group as your production network in the Virtual Lab Properties -> isolated network settings, but the Surebackup job will not be able to match a port group with a special char to the production one resulting a Sure Backup job failure.
It's also true for Hyper-V environments, characters to avoid are:
- the < is assumed to be the beginning of a tag;
- the & is assumed to be the beginning a entity reference.
To resolve this issue, avoid using special characters in the vSphere and Hyper-V entities names.
