Thank you for the effort to backport this bug fix, I have tested the proposed version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.5) and the crash when changing resolution is no longer happening. Unfortunately, after some time (about 10 minutes, much longer than without this fix), the guest freezes.

I reported that in https:/ /bugs.launchpad .net/qemu/ +bug/1787070
I'll change the tag to verification- done-bionic, as this particular issue was corrected. The other issue still exists in QEMU upstream.
