Hi, I set up xen in 2 vmware separate environments and now I want to play with domain migration from one vmware to the other. I don''t want to have external iscsi or nfs or other types of NAS but instead use a small ramdisk. So I will boot a domain xenU with a small ramdisk which will be it''s root, and then I want to migrate this domain from one vmware to the other. In the documentation of xen I could not find any mention of this scenario. Is it supposed to work ? I mean, we have everything we need in the memory of the xenU domain, so I suspect is should work. P.S. I tried with XenCD 1.0 rc1 in both vmware environments, and it did not work, but I suspect there is something else fishy, because "xm save" did not work either. I also saw on the list that some other people have problems with migrating and saving/restoring domains. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

In fact, I''ve been planning on updating the docs to use this as a simple migration example. Cheers, Mark> P.S.

And it did migrated like a charm. Also xm save/restore worked just fine. All in vmware. You definitely should modify the docs, this is the easiest way to test migration.

Could you perhaps describe in more detail what you did (especially with the ramdisk) ? Did you use that as SharedStorage? BTW: If SharedStorage with VMWare (which icsci or special types of NFS are) is an issue (it was till Version 4.x) - there is a recent thread on VMWare mailinglist about SharedStorage with VMWare Workstation (using a virtual SCSI HDD from within two nodes at the same time). Now it seems to works again (via undocumented param diskLib.dataCacheMaxSize = "0"). Unfortunately it`s the Vmware 5 beta board and it`s currently closed to the public - you need an account: http://www.vmware.com/community/thread.jspa?threadID=10731&tstart=30 There is a similar public thread at: http://www.vmware.com/community/thread.jspa?forumID=19&threadID=11257 \ &messageID=109257#109257 regards Roland ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
