I feel like we don't gain much by having an additional warning here. The error from QEMU is already rather clear IMHO. If it's still cheap after deciding which way we go with patch qemu-server 3/4, then we can still go for it, but the warning should mention what the user can do to fix the issue. _______________________________________________ pve-devel mailing list [email protected] https://lists.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
