Hi I''m installing a 3-servers configuration, with iSCSI and Xen, all Gentoo based. I''m using kernel 2.6.29 I''ve got here http://code.google.com/p/gentoo-xen-kernel/downloads/list All the disks are lvm logical volumes shared among the servers and the config files are on a (xfs) volume which is mounted rw on the first server and ro on the others. I''ve managed to build everything, compiled a domU kernel and so on. If I try a migrate I get this: -the original domU gets renamed to migrating-$name -a $name domU appears (paused) on the remote machine nothing else... If I try to suspend the domU I get this: xm suspend test Error: Domain is not managed by Xend lifecycle support. Usage: xm suspend <DomainName> this if I created the domU via xm create. If I use xm new and xm start it just hangs and the domU is not destroyable anymore (had to reboot). Does anyone have an idea? thanks! :) -- Alessandro Storti Gajani Politecnico di Milano - Dipartimento di Ingegneria Strutturale E-Mail: alex@stru.polimi.it alessandro.stortigajani@polimi.it Tel. +39 02 2399 4313 Una vera etica deve essere senza fede altrimenti e'' obbedienza _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

For example, with ext3, when you attempt to mount ro a "dirty" filesystem (like when it''s already mounted rw somewhere else), it''d actually replay the journal, thus possibly making the fs inconsistent for the node that has it mounted rw. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I''m mounting it read-only with the ''noverify'' option just to do some tests. As soon I can find a suitable distributed or cluster filesystem I''ll switch to it. thanks! bye :) -- Alessandro Storti Gajani Politecnico di Milano - Dipartimento di Ingegneria Strutturale E-Mail: alex@stru.polimi.it alessandro.stortigajani@polimi.it Tel. +39 02 2399 4313 Una vera etica deve essere senza fede altrimenti e'' obbedienza -----BEGIN GEEK CODE BLOCK----- Version: 3.1 GITd--s++:aC++USHL++++$P++L+++!EW++N+oK?w---OMV-PS+++PE--Y+PGP+t+++@5--X+Rtv b+++@DI++D+++G++eh---r++y+++ ------END GEEK CODE BLOCK------ _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Ok. I need kernel 2.6.18 on domU. I can have 2.6.29 on dom0 and do the migrations. That''s all I need :) thanks! Alessandro Storti Gajani wrote:> Fajar A.
