Hello,
I'm working on a project involving the dynamic management of Xen domains. I'm using the open source version of Xen (3.2), LVM for storage and Java bindings. I was able to list running VMs by calling VM.getAllRecords(connection). The next thing I'm trying to do is to create a new VM. It's not a problem with the command line tool xm:.

xm create myConfig -c

here are the contents of the config file:

name="debianGuest"
memory=256
kernel="/boot/vmlinuz-2.6.24-18-xen"
ramdisk="/boot/initrd.img-2.6.24-18-xen"
vif=['bridge=eth0']
disk=['phy:/dev/xen-disks/debianGuestRoot,sda1,w','phy:/dev/xen-disks/debianGuestSwap,sda2,w']
root="/dev/sda1 ro"

How am I supposed to do the same thing with Java calls (the problem is with the disk part, other arguments seem rather straighforward)?

       VDI.Record vdirec = new VDI.Record();
        vdirec.location = "phy:/dev/xen-disks/debianGuestRoot";
        vdirec.nameLabel = "debianGuestRoot";
        try {
            VDI.create(c,vdirec);
            //fails: [HANDLE_INVALID, SR, OpaqueRef:NULL]
        } catch ...

Should I create an SR or introduce the partition storing LVM images to Xen somehow? (SR.introduce fails: MESSAGE_METHOD_UNKNOWN)

Regards, Michał Krysiński
