Sorry for the delayed response. On Tue, Nov 20, 2012 at 11:57 AM, George Dunlap <george.dunlap@xxxxxxxxxxxxx> wrote:
xl remus $domain localhost should work. And xl remus $domain remoteHost will work too. Atleast that was the case, when the patches went in a few months ago. If you are using a 3.0+ kernel for the Guest, things should work. There are no other requirements for the Guest/Kernel - HVM wise it should work, since its basically doing xl migrate -l $domain $host continually (just memory).
As far as the kernel double-fault, I have one possible candidate. The dirty page compression could potentially be causing this - since iirc there were some proposals to re-introduce superpages, etc
which changed a lot of xc_domain_restore code. So try "xl remus -u $domain localhost" [disables checkpoint compression].
Nope. Wish I could though :). shriram
