[one-users] edit disks on running vm

[Karsten Nielsen]

OK,

If I am to avoid that.

Then I see my steps as:
1. Create new images from the running vm and make them permanent.
2. Create a new template that has the right bus and target prefixes set
3. Create a vm from that template

Am I mission something ?


If I change the DB then
<DEV_PREFIX><![CDATA[hd]]></DEV_PREFIX><DISK_ID><![CDATA[0]]></DISK_ID><IMAGE><![CDATA[root-20130726]]></IMAGE><IMAGE_ID><![CDATA[49]]></IMAGE_ID><PERSISTENT><![CDATA[YES]]></PERSISTENT><READONLY><![CDATA[NO]]></READONLY><SAVE><![CDATA[YES]]></SAVE><SOURCE><![CDATA[sata/one-49]]></SOURCE><TARGET><![CDATA[hda]]></TARGET><TM_MAD><![CDATA[ceph]]></TM_MAD><TYPE><![CDATA[RBD]]></TYPE></DISK><DISK><CLONE><![CDATA[NO]]></CLONE><CLUSTER_ID><![CDATA[100]]></CLUSTER_ID>

Should be changed to
<DEV_PREFIX><![CDATA[vd]]></DEV_PREFIX><DISK_ID><![CDATA[0]]></DISK_ID><IMAGE><![CDATA[root-20130726]]></IMAGE><IMAGE_ID><![CDATA[49]]></IMAGE_ID><PERSISTENT><![CDATA[YES]]></PERSISTENT><READONLY><![CDATA[NO]]></READONLY><SAVE><![CDATA[YES]]></SAVE><SOURCE><![CDATA[sata/one-49]]></SOURCE><TARGET><![CDATA[vda]]></TARGET><TM_MAD><![CDATA[ceph]]></TM_MAD><TYPE><![CDATA[RBD]]></TYPE></DISK><DISK><CLONE><![CDATA[NO]]></CLONE><CLUSTER_ID><![CDATA[100]]></CLUSTER_ID>
