[Linux-cluster] Xen Live Migration and iSCSI

[Robert Hatch]

Hi, I am configuring a Xen high availability solution which backs onto a
SAN via iscsi.  I am not sure whether to allow the domU's to swap
locally on the dom0 or have a separate swap partition on the san.  My
main question is: When you perform a live migration are the contents of
the RAM and the swap transferred to the new dom0 or is it just the ram
that is transferred? 

If both are then wouldn't it be best to have local swapping so that the
new state is built on the new node.  Would this also be faster as there
would be fewer loads on the san in the long term?

Or is swapping on the san the best way forward?

Thanks for all your help

Regards

Rob
