But the interesting thing would be, why is there an issue with scsi-generic, i.e., the underlying issue for the two Bugs. IIUC, Dietmar had in mind to try to fix those - and thus help all scsi-generic users, instead of working around the issue. The initial question would be: what does the scsi-hd type differently. (maybe hard to tell if they're both complete different implementations) cheers, Thomas _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
