I'm currently evaluating deploying Xen into our environment, and am having trouble with the following issues: virt-manager and xm seem to be very disconnected in their behavior. I stumbled across the problem when I was trying to switch the ISO image presented to an HVM. First, I tried in virt-manager to make the switch while the VM was running. Didn't work - the VM still saw the old ISO image, even though virt-manager had, aledgedly, switched the configuration. So, that didn't work, I thought maybe the VM just needed a reboot, so I shut it down and started it back up. No good - virt-manager showed the configuration as changed, but, once again, the old ISO image was still connected. So, I shut down the VM, removed it from xm (xm delete), added it back to xm (xm new), then went back to virt-manager to start it up. Upon examining the hardware details, I found that the configuration had reverted back to the old ISO image. So, finally, I found that (it seems) the steps I have to take just to switch from one ISO image to another are these:
- Shut down the VM.
- Delete the VM using xm delete.
- Edit the file used to generate the VM.
- Add the VM back using xm new.
- Start the VM.
This seems to be quite a few steps just to switch the media in a drive. Maybe I'm going about this the wrong way and someone can tell me another way to do this. I'm using Xen on SLES10SP1 (3.0.4) and virt-manager 0.3.1. Maybe some of these issues have been fixed in later versions??
