I have no idea what is causing your backend timeout, but your VM
config would be useful information, and take a look at xend.log etc.
on the host for any related errors (if you have access to it). I'm
running OpenBSD 6.4 just fine under Xen; however my Dom0 is only 4.4.4
(dmesg attached).
Note that in your 6.0 dmesg, you have "wd0 at pciide0" vs. my "sd0 at
scsibus1" via "scsibus1 at xbf0"; the man page for xbf(4) indicates it
was added in 6.1, and that it takes over all virtual disks. As a
workaround, you might try boot -c and disable xbf, which would
presumably present your disk via the emulated IDE controller.
