Re: [Xen-devel] Xen-unstable and Remus

[gilberto nunes <gilberto.nunes@xxxxxxxxxxxxxxx>]

HI again

I recompile xen-unstable, and at this time, I have remus running with 
flag --no-net and everything seems good...
I just see that VM on master node change your state between -b----, 
r----- and ---s--, in feel seconds...
I do not know if this is a desired behavior or not...


Thanks a lot
