hi,all
I adjusted time back to year 1900 in windows guest vm. And when i
rebooted the vm, it failed.
It seems that the value of adjustment exceed the range. Any suggestions?
The logs:

You are using Xend which is deprecated and no longer in use. Have you
tried using the latest Xen version and using 'xl' instead?
Thanks.

OK, not sure why you dropped xen-devel (added it on).
I presume you had tried a fix a changed it to a different value?
