</div>This looks like the tdb file (the xenstore db backend) has gotten<br>
corrupted somehow causing xenstored to crash (which isn't a terribly<br>
useful reaction).<br>
<br>
Since there is no persistent data in xenstore you could try removing (or<br>
moving aside) /var/lib/xenstored/tdb.<br>
<br>
It might be worth fsck'ing your filesystem and otherwise checking your<br>
disk integrity -- those IO Errors are slightly worrying.<br></blockquote><div><br></div><div>I have reinstalled all xen packages before your response. Now it seems to work fine. What is more I have checked my filesystem. Fsck fixed some issues. I'll understand that in the future I should start with removing tdb file.</div>
