At least part of the problem happens before this log starts.

OK no smart extended test has been done, but also no pending bad or
relocated sectors, and no phy event errors either. So the write (10)
error seems isolated but it's still really suspicious, so I'd start
replacing hardware.

The only thing that suggests it might not be hardware are all the kvm
related messages in the kp. So if you've changed kernels, or VM
configuration recently, then I'd revert. That's the limit of the most
likely software explanation. If there's no recent software changes,
then it must be hardware.
