[one-users] Attaching second disk

Wed Aug 1 01:48:59 PDT 2012

Hi, 

I had a simular problem, not exactly the same error message, but also related to attaching hot-plug disks to KVM guests. I updated to the latest CentOS version and updated qemu and libvirt to the latest (centos6.2) versions. This fixed one issue. Als as Ruben states SCSI hotplug does not seem to work. I also did not get it to work properly with IDE (hd). With virtio this went without any issues (prefix: vd). 

cheers, 

rogier
