Re: [Xen-devel] DomU clock jumps forward then freezes after Dom0 reboot

[CÃdric Schieli <cschieli@xxxxxxxxx>]

Hello,

I can confirm my problem reported here
http://lists.xensource.com/archives/html/xen-devel/2010-10/msg00057.html
is the same.
DomU kernels affected by the migration hang are also affected by the
save/restore hang. Reverting "x86, paravirt: Add a global
synchronization point for pvclock" also fix the save/restore hang.
After doing save/reboot/restore (which led to a hang), migrating it to
a host with a longer uptime will unblock the domain, but the wallclock
will be several hours forward. Migrating back will block again.

Regards,
CÃdric Schieli
