TIA. > Yes, I re-tested with latest qemu-kvm.git master branch (commit: 0a948cbb). I found the qcow2 image 'disk error' issue can't be reproduced in latest tree. And, I can still reproduce it against commit e54f008e (May 9) as I reported for this bug. Any recent patch has been checked in to fix this issue? Maybe, Jan's "kvm: i8254: Fix conversion of in-kernel to userspace state"? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
