We are currently using VMWare Server (with Debian as the host) to perform a restore test service to clients. Basically we take one of their recent backups, and restore it into a VMWare VM to confirm that their backup will produce a working system on restore. VMWare allows exporting the tape drive device into the VM, and so something like the Veritas Backup Exec IDR (Intelligent Disaster Recovery - you build a CD beforehand and just boot that in the event of a disaster and it asks for the most recent tape and rebuilds the system) "just works". There are some very minor problems with going from a physical system to a virtual system, but the process works well. After we have restored the system we then provide access (remote or local as required) to the client for them to confirm that everything looks okay. Is exporting SCSI "generic" devices (eg tapes, scanners, cd burners, etc) on the Xen roadmap at all? I''m pretty sure it isn''t supported currently but please correct me if I''m wrong!

I don''t know if/when single LUN exporting will be supported..

Re: [Xen-devel] Exporting SCSI Tape devices to HVM DomU
Hi. We posted the function of allocating the whole HBA, because we want to use the tape device in HVM domain. see, http://lists.xensource.com/archives/html/xen-devel/2007-07/msg00450.html http://lists.xensource.com/archives/html/xen-devel/2007-07/msg00451.html http://lists.xensource.com/archives/html/xen-devel/2007-07/msg00452.html http://lists.xensource.com/archives/html/xen-devel/2007-07/msg00453.html http://lists.xensource.com/archives/html/xen-devel/2007-07/msg00561.html http://lists.xensource.com/archives/html/xen-devel/2007-08/msg00002.html Best regards, Horikoshi Pasi san wrote:---------------------- Sent: Sun, 12 Aug 2007 18:16:11 +0300 Subject: Re: [Xen-devel] Exporting SCSI Tape devices to HVM DomU> On Sun, Aug 12, 2007 at 10:17:56PM +1000, James Harper wrote: > > We are currently using VMWare Server (with Debian as the host) to > > perform a restore test service to clients.
