Comment 1 nucleo 2017-07-20 22:10:04 UTC

I don't know what causes this bug.

I assigned it to qemu because downgrading to qemu 2.8.0 fixes bug but maybe this bug should be fixed in xen? Then it should be reassigned to xen.

Comment 2 nucleo 2017-09-10 10:16:53 UTC

Updating qemu from 2.9.0-5.fc26 to 2.9.1-1.fc26 fixes redirection.

Comment 3 Cole Robinson 2017-09-11 18:41:08 UTC

Good to hear, thanks for confirming. Closing this then since 2.9.1 is heading for stable
