Created attachment 133550 [details] xorg log when graphic interface doesn't show Guest failed to start graphic interface when spice-vdagentd started and auto resize enabled with guest os running kernel 4.12. If I disable spice-vdagentd or disable auto resize or revert to kernel 4.11, then desktop start just fine. This has been tested with both fedora 26 guest on gentoo host and fedora 26 host. Also tested with archlinux guest on gentoo host. And both fedora 26 with gnome/wayland and fedora 26 with cinnamon/xorg have the same problem. Related package versions: spice-vdagent-0.17.0-2.fc26.x86_64(fedora) qemu-2.9.0(gentoo) spice-gtk-0.33(gentoo) spice-protocol-0.12.13(gentoo) spice-0.13.3(gentoo) The xorg log is attached.

"Failed to start"? Do you mean that the boot process hangs, and you never get to the login screen window? Or does Xorg tries to start, and then dies? Something else? Is there anything relevant in dmesg?

Or does Xorg tries to start, and then dies? > Something else? Is there anything relevant in dmesg? If I use gdm on fedora 26, then the graphic login screen never shows up. I can only switch to a tty. If I use lightdm on fedora 26, then most of the time I can reach graphic login screen, but never be able to see the desktop after login. Here is some dmesg maybe relevant: [ 4.904916] IPv6: ADDRCONF(NETDEV_UP): ens3: link is not ready [ 4.905183] 8139cp 0000:00:03.0 ens3: link up, 100Mbps, full-duplex, lpa 0x05E1 [ 5.011953] bridge: filtering via arp/ip/ip6tables is no longer available by default.

And AFAIK fedora gdm use wayland and lightdm use xorg by default.
