I have a serious issue with some Virtualmin installation that today stopped to create virtual server after upgrading Webmin from 1900 to 1910. The issue seems to be related to the fact that the IPv4 address is no more recognized from the Webmin networking manager and than from the Virtualmin virtual server creation process.
Trying to create a new VIrtual Server in the usual way I now get this error: "Failed to create virtual server : New virtual server has no IP address! Perhaps Virtualmin could not work out the system's default IP."
This happens because the configured IPv4 seems to be no more catched by the Virtual Server creation process: going to the "Create Virtual Server" page and than in the "IP address and forwarding" tab, the option "Network interface" -> "Shared, on IP" is cheched as usual, BUT the machine IPv4 is no more listed near it!!
The same option in the "IPv6 network interface" still regularly shows the IPv6 address.
Going to the WEBMIN -> NETWORKING -> NETWORK CONFIGURATION, the NETWORK INTERFACES page says that the network interface I'm using has a 'No address configured' inside the IPv4 Address column, but I can connect to webmin using the IPv4, so I presume that the issue it related to a wrong way Webmin is now using to pass the IPv4 address information to the Create Virtual Server process
Is there a way to fix this issue?
Thank you in advance for any hint
(virtualmin in installed on a CentOS Linux 7.6.1810 virtual machin, on ESXi v 6.5, and all was working normally before upgarding webmin....)
