Can you correlate the issue I believe this has been seen on a range of releases so that includes QEMU 4.2 and 2.12. We do have custom patches but nothing in the SATA/AHCI code. I’m not familiar with the storage backend but in the RCA for one of the incidents the engineer identified an explicit write that hit the MBR. This seems to suggest QEMU is mistakenly
translating a normal guest write to sector 0, probably following an earlier write failure. Regards Simon |
