[one-users] FAILED to create VM in iSCSI targets+CentOS6.3 x86_64+KVM

[Jaime Melis]

Hello Lawrence,

could it be that tgtadm got stuck and didn't remove one of the images?
Could you try removing the image manually in tgtd? Off the top of my head,
I think the commands were: "tdt-admin --delete <TID>" and you can get the
TID from "tgt-admin --dump" (I may be wrong, though).

We've found tgtd to hang at times.

regards,
Jaime
