Adding more ram solved the issue. I had 4 CPUs 8 Gig, problem raised with 8 CPUS 8 Gig, now I have 8 CPUs and 12 Gigs - no problem: the machine swaps a bit, but no errors. There might be a small bug in the kernel, but I think it is not worth the investigation for a 11.3 release. Or maybe in qemu fake scsi api... In any case, the discussion should belong to virtualization mailing-list. Sorry for the noise, Luciano. -- /"\ /Via A.
