Yes, I missed something obvious. I was overthinking things.

Boot arguments _are_ passed to the kernel correctly. The part that I
missed is that they are passed literally. I had used the following:
xe vm-param-set \
uuid=$VM_UUID \
PV-bootloader-args="--kernel=/boot/kernel/kernel --args='vfs.root.mountfrom=ufs:xbd0s1a,kern.hz=100,boot_verbose=1'"
This meant that what the kernel saw for vfs.root.mountfrom was "'ufs:xbd0s1a", so it was
ignoring it becuase there is no "'ufs" filesystem type. By removing
the single quotes around the "--args" portion, the kernel boots just
fine. btw: "kern.hz" is 100 by default, so that part isn't needed
either. The following PV-bootloader-args command allows the VM to
boot normally and unattended:
xe vm-param-set \
uuid=$VM_UUID \
PV-bootloader-args='--kernel=/boot/kernel/kernel --args=vfs.root.mountfrom=ufs:xbd0s1a,boot_verbose=1'
So, I'm willing to call it a win!
