Hi,
Thanks for additional information. The engine log actually shows that slclone started ok: "VM slclone c6c56d41-d70d-4b9b-a1cb-8b0c097b89a0 moved from PoweringUp --> Up" Can you explain what problem are you experiencing in that VM? Also, could provide the vdsm log from the same timeframe?
Gianluca
The Vm doesn't boot. As I wrote in the other e-mail:
" The problem is that the cloned VM recognizes the disks in reversed order
See these images where sl1432 is master slcone is the clone
disk layout in details pane seems equal with boot disk the one that appears as the second, but the master boots ok, the slave no. Disks are swapped
Master VM disk details: https://docs.google.com/file/d/0BwoPbcrMv8mvSWNVNFI4bHg4Umc/edit?usp=sharing
Clone VM disks details: https://docs.google.com/file/d/0BwoPbcrMv8mvM1N0bVcyNlFPS1U/edit?usp=sharing
Page with the two consoles where you can see that vda of master becomes vdb of clone and vice-versa: https://docs.google.com/file/d/0BwoPbcrMv8mveFpESEs5V1dUTFE/edit?usp=sharing
Can I swap again in some way? In VMware for example you can see and edit SCSI IDs of disks...
" What is important here is to check the boot properties of both devices as they are configured for the master and clone. They might not be swapped, the order in the console is not necessarily the issue here. Please attach vdsm.log with times of both machines boot. the properties of the devices boot should be part of the startup command so it should help to investigate the issue. Thanks
