vnc: 0.669 graphic: 0.308 mistranslation: 0.278 network: 0.273 semantic: 0.270 device: 0.251 other: 0.178 instruction: 0.142 socket: 0.141 boot: 0.009 assembly: 0.007 KVM: 0.003 reverse vnc to unix domain sockets does not work I tried to connect to a unix domain socket, but failed. $ qemu -vnc unix:/tmp/my.sock,reverse connect(unix:/tmp/my.sock,reverse): No such file or directory I guess it is because unix_connect does not remove characters after first comma. Looks like this should work nowadays (of course you need to start a listening program first), so closing this bug ticket now.
