Hi Jeremy,
These days I tried PVOPS kernel on xen 3.4.3, when do live migration
testing, found
I could not migration back and guest hangs, any access to guest result
in hang.
After 3 to minutes guest seems to come back without doing anything.
Tried older kernel(2.6.32.15) it worked fine, but 2.6.32.16 did not,
after this
release for 2.6.32 stable tree, the first migration guest will hang.
with the latest
PVOPS(xen.git), migrate to remote server worked but migrate back will
failed.
Checked the changes between 2.6.32.15 with 2.6.32.16 and found when
revert the
commit 8a22b9996b001c88f2bfb54c6de6a05fc39e177a in upstream, migration
test work
fine.
Any advice will appreciate.
Thanks,
Joe

2.6.32.16 is quite old, why are you not running the latest stable
release? There have been several fixes to migration since then.
I'm a bit confused though, 8a22b9996b001c88f2bfb54c6de6a05fc39e177a only
went in at 2.6.32.18 (as 9c55fad24be2f417233f5ea3959ade85756fda5f) so
should make no difference to 2.6.32.{15,16}.
Ian.
