Hi Oliver, I read the openqa autoinst-log.txt and reproduced the issue on my local box today, The following are some information for your reference, hoep it can workaround the issue for you: 1. If guest os is leap42.3+ and machine type <=2.3 in qemu cmd line, the issue which mentioned by c16 can be reproduced. 2. If guest os is sles 11sp4,12+ or 15, the issue which mentioned by c16 can NOT be reproduced, whatever the machine type is. 3. This is a new issue, not the same one that described by c1. Is it possible for you that adjust machine type to 2.4+ in openqa environment as a workaround? do you have anyelse testcases which need machine type 2.0?
