+Without this patch, x86_64 images would show invalid EDSCA key errors
+with sshd from openssh (but not dropbear) during init. 
+
+This would cause problems with operation with some distros where EDSCA 
+keys were mandatory. The issue was present in qemu 2.2.1 and not in 
+2.3.0-rc0, bisected to this commit which was then backported.
