https://bugzilla.kernel.org/show_bug.cgi?id=52821 Summary: ata_piix ATA_HOST_IGNORE_ATA for Hyper-V also affects Virtual PC 7 Product: IO/Storage Version: 2.5 Kernel Version: 3.4+ Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: IDE AssignedTo: io_ide@xxxxxxxxxxxxxxxxxxxx ReportedBy: linuxuser330250@xxxxxxx Regression: No [PATCH 2/2] ata_piix: defer disks to the Hyper-V drivers by default Sat, 14 Apr 2012 16:53:16 +0100 https://lkml.org/lkml/2012/4/14/136 This patch apparently also affects Virtual PC 7.0.3 for Mac, with the result that only the emulated CD/DVD drive is visible to the system due to a missing paravirtualised driver for the ATA device. An installation of Linux (with a kernel 3.4 and newer) in the emulated environment of VPC7 is therefor impossible. The problem seems to be that VPC7 also provides DMI 2.3, which also contains the strings "Microsoft Corporation" and "Virtual Machine" -- just like Hyper-V. VPC6 (Connectix Virtual PC 6.0) is not affected. (UNCONFIRMED, but 99% sure: there cannot be "Microsoft Corporation" in it, because it was from Connectix!) I don’t know how, but piix_ignore_devices_quirk should either be more thorough in identifying Hyper-V or it should confirm that it is not running inside Virtual PC. I would be happy to help with inside data, like a DMI dump or anything, but you’d have to tell me exactly what to do. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
