HVM migrate failed on both xen 4.1 and xen 4.2
Hi all,
These days I am testing xen live migration with xen.
The result is that:
PVM migration works well all the time.
However, HVM windows vm migration always failed. I'm using xen 4.1
and 4.2 with NFS as shared storage, and both failed with HVM migration.
We are mainly using xend toolstack. After searching for the error messages, I
found lots of people had this problem, and it related to hvm restore function
bug.
Could anyone help us? Thank you very much!
