Title says it all. I have Parallels Desktop Pro 15.1.4, running three VMs (Windows 10, Ubuntu 18.04, and CentOS 7). After updating to macOS Catalina 10.15.6 yesterday, all three VMs have been unable to get their networking working. All VMs used the Shared Network setting. Has anyone else experienced this? Or conversely, is using the same versions of Pro and Catalina and not had any trouble? Suggestions for troubleshooting would be welcome!
Disclaimer: Most of my troubleshooting efforts were in an Ubuntu 18.04 VM, because that is the VM I use the most. I did reinstall Parallels Tools, without effect. Changing types of networking (shared, host, bridged) changed nothing. Disabling and re-enabling the network also did nothing. I could find nothing in the Ubuntu logs, other than that the Network Manager failed. I may have just discovered a workaround, however: Changing the Parallels Desktop Network prefs to hand out IP addresses in the 192.168.0.0/16 range instead of the 10.0.0.0/8 range. As of this writing, all three of my VMs have live networks after restarting them. Are there logs somewhere that would help diagnose networking issues at the Parallels Desktop level? Perhaps a setting I can change to enable debug logging?
