Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Daniel van Vugt (danv) Assigned to: Nobody/Anonymous (nobody) Summary: kvm image corruption Initial Comment: Creating a new bug from my original problems detailed in bug 2490866, because that technically is a different problem. Reproduced with kvm-83 and kvm-82 vanilla. Host: Ubuntu 8.04 amd64, Intel Q6600 Guests: Windows 2003 Server, Windows 7 beta at least. After shutting down the guest cleanly, it's image file is (often but not always) corrupt and unbootable. A fact confirmed by the change in information reported by "qemu-img info" Example 1 (qcow2 image): $ qemu-img info windows7beta.qcow2 image: windows7beta.qcow2 file format: qcow2 virtual size: 20G (21474836480 bytes) disk size: 5.0G cluster_size: 4096 Snapshot list: ID TAG VM SIZE DATE VM CLOCK 1 Fresh_install 1.3M 2009-01-09 15:34:31 00:00:00.000 2 Activated_kvm-82 1.3M 2009-01-09 15:43:27 00:00:00.000 $ qemu -m 512 -usbdevice tablet -redir tcp:3389::3389 windows7beta.qcow2 & (use and then shut down windows) $ qemu-img info windows7beta.qcow2 image: windows7beta.qcow2 file format: raw <---------------------------- INVALID virtual size: 5.0G (5353566208 bytes) <--------- INVALID disk size: 5.0G $ qemu -m 512 -usbdevice tablet -redir tcp:3389::3389 windows7beta.qcow2 -S & (qemu) info snapshots Snapshot devices: ide0-hd0 bdrv_snapshot_list: error -95 (And the image won't boot) Example 2 (raw image converted from Example 1): $ qemu-img info windows7beta.raw image: windows7beta.raw file format: raw virtual size: 20G (21474836480 bytes) disk size: 4.7G (Install and test lots on the guest) $ qemu-img info windows7beta.raw image: windows7beta.raw file format: raw virtual size: 7.5G (8049315840 bytes) <--------- INVALID disk size: 7.5G (And now the image won't boot) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2525768&group_id=180599 -- 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
