virt-manager crashed when opening a VM on remote host

[kraynovm]

I've successfully installed virt-manger by the following fix https://github.com/jeffreywildman/homebrew-virt-manager/issues/170#issuecomment-878824365 on BigSur. But when I'm trying to open console or properties window to a VM virt-manager just crashed.

Same scenario for me except I'm on Catalina 10.15.7. Any update on resolution?

[louisza]

Same scenario for me. On Big Sur.

[irtec]

[obazda20]

same on macOS Big Sur Version 11.4

[tinsjourney]

did anyone find a solution for this ? still having the issue even if I'm using repo from @Krish-sysadmin, as mentioned https://github.com/jeffreywildman/homebrew-virt-manager/issues/184#issuecomment-922546389

Issue still persists. Mojave 12.0.1

In my case virt-manager crashed only if a VM with SPICE and VNC graphics was running. If this is the same for you, please test, if this workaround helps:

• stop the VM
• edit the VM settings with virt-manager
• remove the VNC display
• add it again (Listen type: address, only localhost)
• start the VM

The different order of adaptors fixed it for me.

This worked for me also

This has worked very well for me. Thank you!
