Hello. I have installed the virt-manager port on macOS Catalina:
The following ports are currently installed: virt-manager @2.1.0_0 (active) Alas, on launch I only get an error message stating that the display can't be opened. → virt-manager -c 'qemu+ssh://user@host/system?socket=/run/libvirt/libvirt-sock' --debug [Sa, 30 Mai 2020 00:59:11 virt-manager 12280] DEBUG (cli:203) Launched with command line: /opt/local/Library/Frameworks/Python.framework/Versions/3.7/share/virt-manager/virt-manager -c qemu+ssh://user@host/system?socket=/run/libvirt/libvirt-sock --debug [Sa, 30 Mai 2020 00:59:11 virt-manager 12280] DEBUG (virt-manager:176) virt-manager version: 2.1.0 [Sa, 30 Mai 2020 00:59:11 virt-manager 12280] DEBUG (virt-manager:177) virtManager import: <module 'virtManager' from '/opt/local/Library/Frameworks/Python.framework/Versions/3.7/share/virt-manager/virtManager/__init__.py'> (virt-manager:12280): Gtk-WARNING **: 00:59:11.316: cannot open display: I have made sure to enable ForwardX11 and ForwardX11 in my SSH client config, and X11Forwarding in the SSH-Daemon config. I can also use the same connection URL successfully with "virsh". What am I missing? Do I need to install a separate X-Server on my Mac? -Ralph
