Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Fabio Coatti (cova) Assigned to: Nobody/Anonymous (nobody) Summary: qcow2 images corruption Initial Comment: I'm running a 32bit vm under x86_64 AMD host with kvm-74. using raw image all works fine, but with qcow2 image I'm able to get deep fs corruption with a disk intensive operation like kernel compilation. it happened every time I tried, and -no-kvm-irqchip didn't make any difference. I've browsed the archives for hints, but no luck.
