[Xen-devel] [PATCH RFC v2 0/9] Preliminary working version of live migration

[Jaeyong Yoo <jaeyong.yoo@xxxxxxxxxxx>]

Hello all,

Me and my colleagues have finally made a working version of live migration
in xen-on-arndale. Using this patch series, we can xl save/restore and 
xl migrate <domid> <ip> successfully. 

I have to further test the stability and the performance, I would like to 
get some comments and reviews if anything may not nicely fit to the xen 
framework. 

It is quite preliminary version, but I hope it could be a start for 
supporting live migration in xen on arm.


Best,
Jaeyong
